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.
