Reflection on Uses of Chemical Studies

Chemistry can be considered a great factor of help, but the real use of chemistry is its study. Chemical studies can tell us a lot about the outside world and industry, as well as make correction and interrogate modern inventions. In this reflection, I will tell you on how chemistry studies affect the modern world.

As we all know, elements make up most of our world, which react in different ways with each other. The first major aspect is safety and security of the world. Chemistry does not allow people to create the absurd and innovative inventions, but limits the resources. For example, there cant be potassium inventions that can interact with water, because that equals to a violent reaction. Can you see the message, chemical safety limits our development. Although our technology is thriving, some inventions are denied due to chemical awareness.

Although the first factor was a con, the secondary aspect is a pro. Chemical studies can also improve technology and development. Chemical reactions also have positive impacts on the world and produce various uses. Therefore, the variety of uses can help in the creation of various instruments and inventions. Industry could also thrive and improve in safety/effectiveness.

For the last factor, I desired to express some facts in attempt to show how big of a role chemistry and its studies play in the real world. When I look at it, chemistry and elements are found everywhere through the world. They actually make up everything around us. Due to this fact, everything is based on it. Chemistry forms the very base of inventions and industry, if it does not pass the chemistry, Access Denied!

In conclusion, I have learned many things from this unit including how chemistry affects the world. There are many other minor factors but in my opinion these three were the main ones. Over all, this unit was really exciting and I look forward with eagerness to the ones that follow.

Chemistry Reflection

Throughout this whole unit, I really learned a lot about chemistry and the ways it can affect our planet. There are some main factors that I want to determine that bounce back and forth throughout the whole unit. The first main aspect would be the covalent and ionic bonds that are formed. An ionic bond is the attraction between two oppositional charged ions. (positive and negative ions get attracted). Unlike the ionic bonds, a covalent bond is where the two different atoms share electrons to satisfy each other. Therefore, these two bonds are a major and crucial factor in the chemistry world. Another important factor and basic aspect of chemistry is the periodic table. The periodic table is the base of chemistry, it lays out everything in a visible point. We started off the unit by learning this table itself. I still remember not having a clue, but now, I fell like an expert in it. It defined for me the atoms and how they are similar or different. How they combine and form specific bonds, as well as the sharing of electrons. I just remember the past, and just now I see how much I have truly learned. I could surely say that this was a topic I learned most from. The next aspect I wanted to share was the acids and bases, which included out last lab. I studied the difference and similarities between acids and bases. I also received a chance to use my knowledge in the last lab.

To conclude this reflection off, I believe that I learned a whole lot from this topic and unit. I enjoyed the activities as well as the experiments that went with them. This unit was a huge success.

In this current event I will be telling you about an unusual event. It will be about the world of animals and what effect they have on the world around us. So here we start. These five species of tree-dwelling snakes are probably the worst nightmare for specific people with great fears for snakes. They have the great ability to “fly”, and they do this by flinging themselves from branch to branch. These are as well very dangerous for animals and our society. Jake Socha, a biologist from Virginia Tech, was the most recent person to study and discover this species. In order to do this, Socha and his colleagues designed an experiment that would include this snake. The forced the Chrysopelea Paradisi snake to leap from a branch, on top of a 15 meter high tower. Four unique cameras filmed this event which allowed Socha to establish a 3-D reference and reconstructions of the animal’s body during this specific flight. His current data were recently presented on the American Physical Society Division of Fluid Dynamics; this fair took place in Long Beach, CA. After all the data was cleanly looked through, the scientists and biologists concluded a very interesting but puzzling discovery. Firstly, the snake never reached gliding state (one in which the forces generated by their undulating bodies exactly counteract the force pulling the animals down, causing them to move with constant velocity, at a constant angle from the horizon) Nor did the snake simply fall and stumble to the ground. This fact drastically puzzled the scientists and they were startled by this intriguing fact. Later on, Socha stated some key factors that determined the facts and finally put the puzzle together. The snake is basically forced upward, stated Socha, the upward aerodynamic force is heavier than the snake’s weight, which therefore allows the snake to be pushed upward. This factor demonstrates that the snake will be continually pushed upward, but newest research has simplifies that is a short lasting component.

In conclusion, this fact about snakes has been very interesting and I look forward to expressing my love for animals. I really hope I read some more exciting articles.

Reflection

I personally believe that this current event can teach people a lot about society and animals although it is very unique and specific. Here are some aspects in which it can accomplish his goal. Firstly, it demonstrates knowledge of animals and the ways their body work and how they are composed. In this case, reptiles would be more appropriate due to the fact we are talking about a snake. Secondly, it partially shoes you some air components and dynamics which allows people to reflect on their aerodynamic skills. Thirdly, it shows how scientists work these days to establish a “safe landing” or “complete mission”. The newest type of technologies enters the spotlight and different problem solving ways are produced.

After all, this is a great way to enhance our learning. I really found this event interesting and hope to learn some more interesting facts along the way!

Holes In Martian Moon Mystery

Phobos and Deimos are the only 2 moons of Mars. Both of them have been closely observed and studied. Recently, a new and very intriguing discovery took place on Phobos. Following a couple of studies, scientists have concluded that more than 30 % of the moons interior is empty space. This moon seemed to be unusually light. Phobos is 16.8 miles long and has a craves and lumpy surface. This was the first fascinating aspect of this unique moon.

Many people state that now this feature was presented, Phobos can be a space shuttle stop. Sadly for them, this is not yet been confirmed but surely swipes away the fact that Phobos might have been an asteroid, caught in the gravity of Mars. This fact will lead us to our next step of explanation. Many astrologist's have surmised on what Phobos could have been. Some say asteroids while others have totally different perspectives. No one knows, but scientists are sure the final equation is close. Although this discovery does not tell many physical features, it can throw out some conclusion, such as the asteroid one, stated Tom Andert. Andert is a planetary geophysicist. He personally was a part of this research and gave some valuable information to NASA. What made observing and measuring Mars was the spacecraft named Mars Express. This specific craft left Earth in 2003 and since then was orbiting Mars.

Next, a large group of scientists wanted to find out the density of Phobos.If two objects are the same size, but ones more dense, then it will contain a higher mass. This is the base on which the scientists relied on for their tiny experiment. To find density, you need volume and mass. Due to the fact that they already had the volume, the mass was the missing piece to the final puzzle. They accomplished this by studying the gravitational force of Phobos. Once Mars Express neared Phobos, it was attracted from its gravitational pull. By studying the motion patterns of the spacecraft, they could successfully determine the gravitational pull. With that in their hands, now they had the mass on its way. The density of Phobos 1.87 grams per cubic centimeter. This suggests that Phobos s not made of rocks that can be found on the top of Mars. Therefore, the moon Phobos is not a pure asteroid.

In conclusion, this discovery has presented a whole lot of information to the world and I personally hope they will deploy them to some new discoveries.

Reflection

I truly believe that this discovery can teach the world a lot due to the fact that I have learned a lot from this video.

Here are some of the aspects that remained in my mind after this current event. Firstly, I reminded myself about density,

gravitational pull and other components of astronomy. This was truly perfect revision for me because some of the facts were

flowing away. Secondly, astronomy information also caught my mind. Mars and its complex features caught my attention

so the research really helped me flourish. Finally, information about Phobos and its features also rang a bell in my head.

Researching about them was really intriguing and I can assure you I learned a whole lot. I personally adored this topic and it

was another chance to live my astronomy love. After all, this current event was really interesting and I really enjoyed myself

while I was working.

Fireworks Reflection

After exploring this video, I have not only learned about fireworks, but about chemicals and how they combine.

1. How are fireworks capsules designed?

An firework is a very unique shape. It has an aerial car board outside, that is much like a raindrop. At the bottom, there is black powder propellant. In the powder, there is a fuse that finds its way to the center of the firework. This determines the characteristics of the firework and the ways of the explosion. When it comes to the black powder inside, the firework bursts. Along with the black powder, it is surrounded by green pellets on the outside that produce the effects and give off the amazing colors.

2. What safety procedures to they include in the design?

Most importantly, their is a delay fuse. This fuse needs an amount of time to reach the center of the firework and gives people time to run to safety just in case of an explosion. There are two main ways in which a fuse can be lit. Firstly, it can be lit with a fire manually, or electrically from a specific distance. The second main way for safety would be the mortar tube, the place where the firework is released from. Once you lit the fuse, you have enough time to go to safety and the mortar tube shoots the firework in the air, therefore it can not go wild.

3. What are the compounds mentioned in the video? Formulas?

Some compounds in the video might include the following; potassium nitrate (KNO3), strontium nitrate Sr(NO3)2, sodium silicate (Na2SiO3), strontium chloride (SrCl2), copper oxide (Cu2O) and a couple of extra others.

4. Which element is extremely important for fireworks to work properly? What is the fire triangle?

Oxygen is the key element that is important to fireworks. It is the oxidizer, which is necessary to make a fire. Without it, fireworks would not manufacture. The fire triangle basically demonstrates the basic factors of a firework. It shows the three major factors that are needed within a firework. A combustion triangle (another name), basically demonstrates that fuel, heat and an oxidizing agent are a necessary for a firework to work. After all, it demonstrates a fireworks ingredients.

5. What two components do fireworks need in order to produce heat at a certain burning rate?

The two main factors to produce heat at a certain burning rate is an oxidizer and fuel. Without these, there is no reaction. These aspects include potassium perchlorate, potassium nitrate and strontium nitrate. Some of the fuels include sulfur, charcoal, magnesium powder and aluminum powder. As you all may have surmised, the fuel reacts with the oxidizer, in this case oxygen, to create the heat needed. When you differ the fuel, you will get different rates and burning varies. This another example in which the fire triangle comes in handy because it demonstrates the different ingredients necessary for the full reaction.

6. What type of reaction takes place in fireworks?

For every reaction, an chemical reaction occurs. Here is why. In order to include a specific and unique color into the firework, a burning mixture is necessary, which is supplied by the oxidizer and fuel. After this has occurred you can include various colors for effects.

Scientists Discover New Species in the Worlds Deepest Ocean Trenches

For this current event, I will identify and explain to you about the new species that was found on the Peru-Chile trench. This investigation and research was founded by a team of biologists coming from Aberdeen, Tokyo and New Zealand. This new type of snail fish, was supposedly found at a massive depth of 7000 meters. The interesting fact was that also types of crustaceans were also discovered in a new specie. The expedition time period was three-weeks aboard the vessel Solle, which in they explored the deep trenches with modern technologies. One of them included a free falling camera that took 6,000 pictures when falling down. This successful expedition is the seventh one in the organization of HADEEP, which is the cooperation of the Aberdeen University, the Tokyo Ocean Research Institute and the New Zealand National Institute of Water and Atmospheric Research. This team has been exploring great depths for 3 years, but this is the first time of a new specie discovery.

"This expedition was prompted by our findings in 2008 and 2009 off Japan and New Zealand where we discovered new species of snailfish known as Liparids -- inhabiting trenches off Japan and New Zealand at depths of approximately 7000m -- with each trench hosting its own unique species of the fish."

"To test whether these species would be found in all trenches, we repeated our experiments on the other side of the Pacific Ocean off Peru and Chile, some 6000 miles from our last observations." "What we found was that indeed there was another unique species of snailfish living at 7000m -- entirely new to science, which had never been caught or seen before." stated Professor Alan Jamieson.

Back to the second surprising discovery was the crustacean scavengers, that are known amphipods. Many amphipod specialists have stated that many of these creatures are not found in such depths. There must be some sort of secret, because this is the only place where these creatures are found. Dr Toyonobu Fujii stated that fish survival and existence had been an intense question. He also stated that this exploration has provided "deeper insight" into the life of a surviving fish. After, this research has provided many deeper knowledge on survival and will effect the world in a couple of ways and insights.

Reflection

Along with its great facts and meaning, I surely learned a lot from it. This can also affect the world a whole lot. The big affect on society would be a bit about animals and their survival. Although this is not really important, it can be important in some areas. This information can help in survival tips and even affect the human world. I personally believe this article and discovery does affect society, but there is still a lot of research to identify. In my opinion, this article was very intriguing. The facts were really catchy and I thought it would make a great topic. This topic was really interesting and I love it. I really enjoy animals and this was a pleasing experience. After all, it was pleasure reading this.

Bees Reveal Nature Secrets

Bees Reveal Nature Secrets: Extensive Molecular Differences Between the Workers and the Queen

November 2, 2010

http://www.sciencedaily.com/releases/2010/11/101102171606.htm

In this current event, I will be expressing and telling you about the new investigation that has answered very intensive questions. I am sure you will be pleasantly surprised. So come on, keep reading and experience a new adventure through the complex world of science.

This very profound and important investigation was led by Professor Ryszard Maleszka of the Australian College of Medicine, Biology and Environment. He was also accompanied by his colleagues from the German Cancer Institute in Heidelberg, Germany. Their work defines the first details and differences of the “environmentally influenced chemical marking of DNA”. Meaning the difference in DNA and how it affects nature. This specific marking is crucial to brain differences. Now many scientists can notice what genes have to be tuned in order to perform the differences of behaviors between animals and humans. “This finding is not only crucial, but far reaching, because the enzymes that mark DNA in the bee are also the enzymes that mark DNA in human brains,” said Professor Maleszka. This is another important statement that Maleszka pointed out. Due to the fact that the enzymes that mark DNA in the bee are the same with us, people can now deeply study the relationship and tuning of this spectacular find. Another intriguing fact was that more than 550 genes were different in the minds of the workers and the queen. As Malezska states, this is probably the biggest fact that represents the difference in behavior. This specific investigation, also answers one of the biggest questions in life. This study most importantly demonstrates how the outside world is “linked: to the DNA and how the environment can modify our personal “genetic hardware”. These risky and bizarre actions cannot be performed on humans and therefore, humble honey bees are pioneers of this important investigation.

In conclusion, Maleszka has performed one of the most important investigations so far. He has brought research to a whole new level. In my opinion, this specific study can answer life’s most challenging questions and make life easier.

Reflection

For me, this article or investigation, taught me a lot about our complex mind and how it works. Here are some of the main points that stuck in my mind after reading this article. Firstly, due to my curiosity, I researched facts about brain function to make this easier to understand. Secondly, I learned about genes and how the environment can potentially affect. I found this very interesting. Lastly, I learned everything possible about bees and humans and how they connect. This brings up another lesson in which animals are like humans. This is a fact that not many people respect and should be respecting. This topic would connect with animals and survival but at the same time brain function.

To conclude, this article is very catchy and interesting and can be associated mith many different aspects of life.

Major Chemical Spill in Hungary

On October 5, 2010 a major Eco disaster took place in Hungary, in the surrounding Budapest area, mostly impacting rural villages and towns. This disaster supposedly happened after a reservoir damn broke and an 2 meter high massive industrial wave flooded the areas and wiped away any materials in its way. This wave flooded many villages and left a number of streets and houses covered with red-sludge. Hundreds of helpless people were evacuated from villages from this terrible wave. This disaster has so far killed 4 people and injured a hundred others. This chemical wave is slowly spreading through surrounding countries including Serbia. There is also instant actions in how we can stop a terrible scene to happen. Some suggest dams while so suggest different types of ideas. In my opinion, safety measures are drastic because of this risky chemical combination. After all, this combination can potentially take away many lives and this is the fact that we are trying to cancel out. To conclude, this drastic chemical spill took place on October 5, 2010 in the surrounding villages of Budapest and has consisted of great attention. I certainly hope that drastic measures be held to prevent this spill from being a world wide issue.

In my opinion, I think this tragic event fits our topic of class in a couple of ways. Firstly, the chemical spill has a lot to do about chemicals and how they cope. This spill also represents the bad ways chemicals can influence our world. Secondly, this event can also combine with the upcoming essay about effects of harmful chemicals. I truly believe that this topic would be a perfect topic for elaborating on. Thirdly, this event elaborates more on compounds and safety measures that have to be taken when referred to chemicals. God knows when something like this could happen again, but much worse. Those are the times where we have to be ready, because as you have seen, chemicals can kill. To conclude, I personally think this video was very tragic but completed the necessary components of a chemical awareness video.

As I mentioned earlier, this video has much to do about chemical awareness, similar to the Blue Gold which is about water awareness. They both try to make the world a better place by taking action. The videos try to raise awareness about a certain topic that needs instant major attention.

Newly Discovered Planet May Be First Truly Habitable Exoplanet

Summary

A specialized team consisting of planet hunters led by the astronomers at the University of California and the Carnegie Institution of Washington have discovered an earth sized planet (three times the size of earth) orbiting a close by star. The discovered planet is in the middle of the planets "habitable zone" where H2O can exist on the planets surface. If authenticated, this planet can be the first potential planet that humans could actually survive on. To astronomers a habitable planet would be a planet that could actually sustain life, not necessarily a planet that could be lived on. These finding were based on the 11 years of observations at the observatory in Hawaii. Paul Butler of the Carnegie Institutions stated the following, "Our ability to find potentially habitable worlds is now limited only by our telescope time." This newly invention will yet be released in public also including many minor names that contributed to this miraculous discovery. It all started when two planets were found around the dwarf star Gliese 581. This improved the number to six orbiting planets which is the second largest system after ours. The most interesting planet, Gliese 581g is three times the mass of earth and as Vogt stated, enough gravity to hold down an atmosphere. This incredible planet is 20 light years away from earth and had practicably enough characteristics as earth. "We had planets on both sides of the habitable zone--one too hot and one too cold--and now we have one in the middle that's just right," Vogt said. This planet is also locked to the star meaning that the planet does not rotate, therefore, one side is always exposed to light and the other is always exposed to darkness. The planets temperatures range from -31 C - -12 C. In one side, its gets really hot while on the other it gets really chilling and cold. It was a really challenging job to find this incredible planet but the researchers are fascinated on how fast they found Gliese 581. Plus, according to the percentages, they have come to an conclusion that there are possibly billions of planets that have the same attributes. Once again, this planet was really special and many researchers and astronomers hope this planet can actually sustain life. This project was financed by NASA and the National Science Foundation.

In conclusion, there are many other planets to be discovered and finally some day, we hope we will be able to take the human civilization and transfer it to another planet.

Reflection

In my opinion, this article was very useful for developing my knowledge and it made the memories from the astrology unit. Firstly, I learned how hard planet hunters work. They never accept breaks and try to discover planets for 24 hours. There hard work payed off with this event and now we possibly have a habitable planet. I also learned a lot about habitable planets and there aspects. Now I know what type of planet is a habitable one and how it becomes a habitable planet. As I said earlier, this project also brought back memories from the astronomy unit. I now know more about the atmosphere and gravity a planet holds and more about the core of the planet. This article mostly connects to the astronomy unit and I personally think it would help students understand planets a little bit better.

In conclusion, I want to state that this article really helped my mind develop and become stronger. I also hope this planet will become a new earth!

Green PLastic

After I finished watching this video, I learned many things, one being that "Green PLastic has a bad and good impact on the world. Firstly, that Green Plastics are made out of corn, sugar canes, sugar beets and other materials. I also learned that PLA is very effective in producing materials such as diapers, socks etc. These plastics are "green" because they do not use any fossil fuels as raw materials to make plastic. They are also green because they can decompose on their own without even polluting the environment.

Green Plastics also has harmful aspects. I look at it as a cycle. To harvest these crops used for plastic, you need fertilizers which contribute to water pollution. Motor vehicles used for harvesting, transporting, planting etc release carbon dioxide which contributes to global warming. Factories used to produce plastics also need electricity which usually comes from fossil fuels.Many trees would also be cut down which would increase deforestation and less oxygen.

Some compounds I found were methane, water or H2O, lactic acid and carbon dioxide.

These two videos try to tell us what is going on in the world around us and give us interminable ways on how we could improve on its factors. They talk about polluting and the cycle of polluting. They also raise awareness on how the precious world should be treated.

In conclusion, i want to state that this video was really interesting and helped me understand more about the outside world.

Atomic Theory Reflection

Here is the link to the website containing the video:

http://www.101science.com/Chemistry.htm#Chemicals_and_Interactions

Reflection On What I Learned

In my opinion, this video was very interesting and really helped me sum the information we learned in 21 minutes. Here are some factors that I really picked up during his video presentation.

Firstly, the main factors, such as the protons, electrons and neutrons were explained in great detail. The great diagrams and pictures also helped me stick the basics into my head.

The other important aspect I learned was the one with the organization of the atom. He drew where the protons,neutrons and electrons were. He also greatly defined the orbits and orbitals which really helped me understand the electrons job in the atom.

Next, he really deeply explained the mass, number and weight which allowed me to combine and see how they all connect with each other. One example of this would be the atomic number and mass. He demonstrated how they both are used to fond the amount of neutrons.

After that, he stated some very intriguing facts and comments that I have not heard before. What blew mine and his mind is that actually all the things we look at are not really solids but empty space. They just look the way they are because the way lights reflects on them. There were some other interesting comments along the way.

I also enjoyed how he was using philosophy and the philosophers mind. His thinking and explaining made you ask a lot of inquiry question regarding the topic. I also adored how he kept everything steady and mysterious. This aspect really made me eager to watch the 20 minute video.

In conclusion, I want to state that this video had a positive effect on me and hopefully my classmates. This video also helped pound in the swirling information that was orbiting around my head. After all, this video helped me sum up all the information we have learned about chemicals.

Current Events-Most Penguin Populations Continue To Decline

Summary

This interesting article I read was about how the penguin population is decreasing. Not long ago, over 180 penguin biologists, officials and zoo professionals have come together to discuss this fearing problem. They have come to a conclusion that 10 out of the worlds 18 species have had a decline in their population over these couple of years. There are four main reasons of this intimidating happening. Firstly, the population has decreased because of climate changes. One example of this would be the blockage of cold water currents. These cold currents have brought many schools of fish for the penguins to eat. But now, the cold water currents are permanently blocked. Therefore, the penguins do not have enough food to live. The massive icebergs also cause problems for the helpless penguins.

The second main reason on why penguin population has gone down is because of overfishing. The large amount of fishing going on has prevented the penguins from getting their food so now they are fighting for their own food. The catching of fishes means that the penguins do not have anything to eat so lower breading success and vulnerability is a big problem. Penguins are also caught in various fishing nets.

Thirdly, oil spills and chronic pollution have killed many penguins over this time. This oil usually comes from sunken ships and ships crossing the sea.

Lastly, mammalian predators are also a problem. Till now, penguins have lived in remote areas where there has been no animal predators. But now, the introduction of weasels and foxes in different areas has a had a huge impact on small population of penguins.

In conclusion, penguins are in great danger and this is what the biologists are trying to stop.

Reflection

I chose this intriguing article because of my love for animals. I think I learned a lot from this article. It taught me how small aspects that don't really matter to someone, in this case people, can affect other beings, in this case the helpless penguins. Another valuable aspect I learned is actually how much attention is faced toward this problem. I am actually very glad to see that there are many people out there that want to help these penguins. I am also hoping that this article will raise awareness of the endangered animals, not only penguins. I my opinion, people have faced so much to the natural world and forgot all about the beautiful animals that roam through earth. I personally really enjoyed this article and learned quite a lot form it. I am sure that I will keep all the information about monkeys and endangered animals. People should worry about Global Warming or Water Loss, but they should never forget the beauty inside the animals. Remember people, animals have feelings too. They can feel anger, pain, sadness and happiness.

5 New Facts Regarding Water

1. Once evaporated, a water molecule spends ten days in the air.

Honestly, I did not know this fact about water and I found it very helpful. The moment I read this article I thought of a way it could help us gather water. If we knew how much time the molecules stayed in the air, we could predict where the rain would go and how strong it would be. Maybe be could build some sort of machine who could collect the rain and we could have fresh water. In this way water supply could increase. I think that this perfectly connects with the water video due to the fact that it can help the increase of fresh water. It also can connect with Macedonia. My country could take some risks and try to use this useful fact.

http://www.mamashealth.com/water/waterfacts.asp

2. Drinking 5 glasses of water daily can decrease the risk of breast cancer by 79 %, and one is 50 % less likely to develop bladder cancer.

I chose this fact because I found the information very interesting. I could not believe that drinking water can actually decrease the likability of getting cancer. I am really curious why this information is not so known because I believe it can help many people that fear these types of cancers. I am really interested in how the water banishes these cancers. I personally think this is a very important fact and sooner or later it should appear on the news. This can connect to the video because it is one way fresh water is wasted but it used for good deeds. Macedonia could also acquire this fact and start putting it into use.

http://www.all-creatures.org/health/inter.html

3. A human being can go without food for a month, but can go without water for a week.

This fact really sums up the whole problem with water. It basically states that food is much less important than water and sadly, we have much more food than water. Our water resources are slowly going down by the numbers and soon finding water will become an impossible task. This is why the conservation of water is a crucial thing in the world. I my opinion this fact is basically what the whole movie is trying to tell you, to preserve the water!!! This information should also quickly spread through Macedonia and more people should value water more than anything else.

http://www.strange-facts.info/interesting-water-facts

4.There are about 70000 contaminants of water.

This article was very interesting it blew my mind with what I actually already knew. Its complicated to explain. As we all know, there are many pollutants of water but no one would say there are 70000!!! I think this is absurd and whoever those pollutants are, they should be stopped. Awareness of these contaminants should arise and people should start paying attention to the water. I think this is also a perfect match with the topics we are learning in class. I think that Macedonia should also raise awareness and pay more attention to the Macedonian bodies of water.

5. 70 % of the worlds fresh water is devoted to agriculture.

I finally chose this one because I wanted to state how the fresh water is not organized. As we all know, water is a necessity to life. Now if we use this water for agriculture, there is not gonna be enough for the world. Due to this fact, the fresh water should be divided into proper groups so their is enough for everything and everybody. I think this fact connects to the video in a way of organization and how the fresh water of the world should be divided. Macedonia also has many farms and agriculture and this fact is pointed toward my country. People should start thinking of how they treat the FRESH water.

5 Things I Didn't Know About Water

http://discovermagazine.com/2010/may/20-things-you-didn.t-know-about-water

1. Water is everywhere—there are 332,500,000 cubic miles of it on the earth’s surface. But less than 1 percent of it is fresh and accessible, even when you include bottled water.

I thought this fact was really intriguing but at the same time fearful. I chose this fact because this fact has many changed aspects than what we learned in class. Firstly, it states that only one percent of the earths water is fresh, including bottled water. I found this very interesting because many people have been stating that there is only 3 % of fresh water. This relates to our class because we are currently learning about water and how it has affected the world. This fact also relates to my country, Macedonia. Many people do not know these type of facts and in my opinion this is a really important one on the conservation of drinkable water.

2. Cheers! The new Water Recovery System on the International Space Station recycles 93 percent of astronauts’ perspiration and urine, turning it back into drinking water.

I also chose this fact because I thought of it being quite innovative and it brought up a fact I didn't know before. What surprised me in this fact was that I did not know that urine can be turned back into drinking water!?!? I was totally stunned by this comment. I never knew you could turn urine into water. Believe it or not, I am really curious on how they do this. This fact sort of connects with the unit we are studying but could be a real hit on the astronomy unit. Although Macedonia doesn't have much astronauts, the conversion could be widely studied and it could bring us fresh water.

3. Good gardeners know not to water plants during the day. Droplets clinging to the leaves can act as little magnifying glasses, focusing sunlight and causing the plants to burn.

I was personally really amazed by this fact. It added information to my head that would have almost never come to my brain. I did not think of this "formula" this way in the past but his comment really lit up my brain. I am sure many farmers have asked themselves why their plants were burning but its too bad for them, they did not go to a good science class :) But now that I think of it I ask myself, can plants survive the day with no water? We all know that plants need water to survive so this is the only question I have. I also think this fact relates to our topic and it can help the farmers in Macedonia keep the business going.

4. Although many doctors tell patients to drink eight glasses of water a day, there is no scientific evidence to support this advice.

I also chose this fact because the actual message of it was very interesting to me. I have been told many times to drink eight glasses of water per day and I thought the doctors were of it. I guess this fact states the opposite. I am really curious on how many doctors have come to the same conclusion due to the fact that their is no proof. I guess after reading this very persuasive fact I will doubt some other specific thing in life. I think the only connection this fact has is with the world. I think that it is fatal for doctors to be giving such prescriptions if they do not know the outcome over time.

5. Recent evidence suggests that when the solar system formed 4.5 billion years ago, comets had liquid cores. If so, life may have started in a comet.

As soon as I read this miraculous fact it totally blew my mind. I have always been told that life had started on earth after the big bang, but turns out it is a possibility that life started in a comet. If this was actually true I believe that research and investigations would be all over the place. Maybe dinosaurs weren't the first creatures. I really have a lot of questions to ask about this fact and I am sure many people do to. Once again this fact would totally fit in the astronomy unit more than the chemical unit. I really look forward to reading some more information about this fact.

Glogster For Pottasium

My poster on Glogster:

http://dave9.glogster.com/pottasium/

This online Glogster really helped me understand pottasium and the world of elements. Firstly, it explained to me how elements combine on order to form compounds. Finding all the compounds for my element showed me combination and how the valence electrons mix. Secondly, this poster taught me a lot about the whole basic chemical point. I learned how they interacted and their use and chemical properties. Most importantly, I learned about Potassium which was my element. In conclusion, I want to state that making this online poster allowed me to understand the secrets of the chemicals.

Robotics breakthrough: Scientists make artificial skin

Summary

In this fascinating article, it explains how biotech wizards and engineers have successfully created electronic skin that can sense touch. Many people state that this invention will be a great step in the field of robotics. This exuberant new invention reacts the same like human skin when put under different pressures.

Along with this, come very challenging boundaries along the way. One of them is producing a robot with more sensitive arms so I can do everyday tasks and throw away the clumsy robots. “Humans generally know how to hold a fragile egg without breaking it”, said Ali Javey, an associate professor at the University of California. These are the types of things we want to get robots doing to. Another problem of robots is smell and taste but touch is one of the greatest problems every scientist faces.

The “e-skin” made by Jarvey’s team was made by germanium and silicon rolled onto a sticky polyimide film. Using many types of measurements and machines, they have created an invention that can detect pressure enough for daily activities such as typing.

Another aspect that many engineers want to change is the ability to connect the skin to the nervous system. Because of that, we can pain and pressure and this is the ultimate goal for the future.

This is a very intriguing invention that has astounded the entire world. Now I will tell you the major uses this robot may have. Firstly, these robots may help us in the future and in everyday life. For example, robots may do the house work and help you defeat everyday tasks. The second reason for why this e-skin is very effective is because it can send information from nature. For example, we could send one of the robots into space and the information sent back is actually how a person would feel. Remember this e-skin can also feel pressure, humidity and temperature. In fact, it can feel much more than that.

In conclusion I think this invention will really affect society and is a great step in the field of robotics as well as electronics.

Reflection

After all I have read, I am very curious and amazed how much technology has advanced. Although this topic doesn’t have much to do with chemistry, chemistry is a big aspect of the creation of this fascinating invention. As I mentioned earlier, the e-skin was created by mixing germanium and silicon which are to elements on the periodic table. This explains that although the elements are not the center focus, without them, there would be e-skin. What I wan to say is that there is not only the main factor but the secondary factors. This article can also be used as a morale point. Never look at the big, but also look at the details. There is always something more, more detail. I really learned a lot from this article, scientifically and logically.

Finally, I want to state that I am very impressed by this invention and using this article my view towards chemicals and their reactions changed. I am very impressed and I look forward to learning more about the world of chemicals.

Further Inquiry

Here are some questions that I am still curious about.

• How do the filters successfully clean the polluted water?
• What are the major pollutants of the clean lakes and rivers?
• What do people do in order to stop this evil polluting?
• Does polluting kill the food chain as well as plants and how?
• Are there any options that factories can use instead of dumping everything in the lakes and rivers?

Macedonia's Bodies of Water

• What rivers flow through your country?

The main river that flows through the land of Macedonia is Vardar. This lake is also the longest lake that runs through Macedonia. Another river that flows through Macedonia is the Black Drin and is the closest to the border with Albania. Treska is another river that can be found and covers the western part of Macedonia. The Radika also covers western Macedonia and is a tributary to the Black Drin. These are some of the most important rivers but along with them, Macedonia has many artificial lakes. The Ohrid Lake is obe of the most famous and a tourist attraction. This lake is the deepest lake of the Balkans and covers an area of 358 km². Believe it or not, Ohrid Lake covers most of the underwater food-chain.

• Where do the rivers come from? (Include the countries that it flows through)

The Vardar river rises in Vrutok, north of Gostivar, passes through most of Macedonia and finally empties into the Aegean Sea. The Black Drin is a river that runs through Albania and Macedonia and empties in the Adriatic Sea. This river runs out of the famous Ohrid Lake. Treska is a tributary to Vardar. This river rises in the mountain Stogovo and flows through Kicevo to get to Vardar. The Radika rises in the Vraca mountain and flows into the Black Drin. This river is also found in Southern Kosovo.

• Are there any blockages? (Dams, hydroelectric plants

Although Macedonia doesn't have many blockages, a small number of dams can be found in Macedonia. A more known dam in Macedonia is the one on Mavrovsko Ezero or lake. This lake was created when the dam was built up. Another dam that can be found is the one in Matka. Although Macedonia doesn't have much dams, it does have plenty of water conservation laws. The Law on Water protects the rivers and lakes and states the causes of water contamination. Although many factories still contaminate the water, I hope that this law will prevent this ugly cause of water contamination.

• What forms of industry are located on the rivers?

The types of industries that lay near Macedonian rivers have not been specifies yet but I am sure that many factories and even homes pollute the river. At this point, not even the Law of Water can prevent these factories to pollute. In my opinion, it is just a matter of time when factories realize there is less drinking water by the day.

• What springs/natural reservoirs are there in your country? (Lakes, aquifers, watershed)

As I mentioned earlier, Macedonia has a wide variety of lakes. Starting from the Ohrid lake to Prespa. From all I have heard and seen, the lakes have turned out to be more important than the rivers. As I have mentioned earlier, the Ohrid Lake is the most famous lake in Macedonia and maybe in the Balkans. It is well preserved and thousands of tourists visit this famous deHow do you get water to your house?stination. Another important lake is Prespa, and reserve for animals and plants. This lake has been preserved by all the countries it can be found in, Macedonia, Greece and Albania.

• Where does your country get their water supplies from? If it's from your country, do you ship/export water to different countries?

Each city in Macedonia get its own water. When the river water enters the filter, the water is being tested. When the water reaches the certain level of cleanness, the water is let go and flows through pipes into peoples homes.

• How do you get water to your house?

As most of the other people in this community, I get the water to my house using pipes.

Evidence of a Chemical Reaction

In order for this chemical reaction to you have to wait for a couple of seconds. After that, you cam see the chemical reaction developing. First you can see a red eruption on the bottom of the glass. After that the liquid inside turns red. After that, bubbles start forming and an interesting sort of gas is released. This is a chemical reaction because the Bromine and Alcohol combine and make a specific reaction that cannot be replaced.

When the lithium is put into the water it instantly lights on fire. After it has made its drastic way through the base, the fire goes and way and the lithium helplessly floats on the top. This is a chemical reaction because the atoms mix and no physical change is located. It also cannot be replaced, therefore its a chemical reaction.

http://www.youtube.com/watch?v=896vJj6eWYw&feature=related
The minute the cesium is put into the water, there is an instant explosion, sort of like a firework. At the very instant the cesium falls in the water, there is a firework explosion. In the picture at the end you can see how the cesium exploded and it separated into bits. This is an chemical reaction because the change occurs on the inside. It cannot be described in "physical language".

http://www.youtube.com/watch?v=qRmNPKVEGeQ&NR=1
This chemical reaction is very similar with the lithium one its just this is potassium. When it firsts catches on fire there are a few sparks and the fire continues making its way on the water. Its stays on fire for a little while and the fire disappears. The same like the rest, this is also an example of a chemical reaction.

http://www.youtube.com/watch?v=vJslbQiYrYY&NR=1
At the beginning you can see a small fire building up in the bottle. After the fire comes a massive explosion which is why they had protection. After the explosion everything calms down and you can notice only the disturbed water. This is once again a chemical reaction.

This video is my favorite. There is this person with a bowl filled with liquid nitrogen. Now this person pours the nitrogen into the pool. And a sort of cloud forms but disappears and all is left is a very thin layer of liquid nitrogen. As all the rest, this is a chemical reaction.

http://www.youtube.com/watch?v=5n7kBkBcXgo&NR=1

At the beginning of this video there is a long wait. After that you can actually see some bubbles start to form and the bubbles start rising and at one point the jar overflows. The really interesting thing i noticed the more time passed by, the darker the color got of the overflowing liquid. After that there were overflows but instant ones. Like bubbles popping. This is also a chemical reaction because this cannot be returned into original state.

This video was kinda unclear so I will do my best to explain it. The moment he puts the gummy bear the gummy bear next to the tube lights on fire. This intense fire lasts for a pretty long time and finally calms down and returns to its starting position. This is once again a chemical reaction.

http://www.youtube.com/watch?v=zrNA8-eipGE&feature=related

fter the glass was put under the light and all the needed materials were included (salt crystals, turpentine, food dye) you have to wait 2-5 seconds for the chemical reaction. When it actually happened, I was startled. To me, it looked like some magical moisture and you could actually see the water moving magically. I also noticed there was a sort of gas released from the top of the glass of water. This is once again a chemical reaction, a magical one.

What I Learned:

• I learned about the Lewis Dot Diagram and what they represent. Which is the valence electrons of an element or atom.
• About the attachment of chemicals and how chemicals combine.
• I learned the condition the atoms have to be in order for them to be able to combine. For example, -1 can only combine with 1.
• How many electrons each shell should contain. And what is the best fit for shells.
• I also learned what a val ant electron is and how it is expressed in the Lewis Dot Diagram.
• The biggest reason that I learned many points is because all the diagrams we drew in class.

Whats Still Not Clear:

The only thing thats not clear to me is the periodic table itself. I just need a little more help on the translation of the periodic table.

What I know:

• Some chemicals can be hazardous when interacted with each other.
• When two chemicals interact, the have a specific and unique reaction.
• Chemists study these interaction and chemicals.
• Mixing dangerous chemicals requires a wide amount of perfection and safeness.
• Some chemicals are too dangerous to be mixed (can cause explosions and other hazardous reactions)

Want To Learn:

• How the molecules and atoms mix to make the explosions.
• The combinations between chemicals.
• More about the people who study atoms and chemicals.
• Hopefully, I would really enjoy if we created an experiment requiring mixing of chemicals.
• More about the elements and what happens when they interact.

My Goals In Science:

1. To keep up the good grades and expand my knowledge throughout the whole year.

2. Always be prepared for class and most importantly be eager to learn.

3. Treat my classmates and Mrs.M with respect so they can treat with with respect too.

4. Never give up on any assignment and hand in all homework assignments on time.

5. Cooperate with all my classmates so we can be more effective.

6. Finally make this year an year to remember all your life.
