Unit Question
Unit Question: How does studying chemistry give us a better view of how industry affects the world?
When you study chemistry you learn a lot about Chemical Reactions and what negative effects they could have. In industry you learn about how factories dispose of waste and release chemicals into the air or water. You combine this information and can see how some chemicals destroy the environment and what they can react with. For example, in agricultural pollution I learned how Nitrate and Ammonia effect the environment and the effects they have on humans and animals. Also, when you learn about bonding you can see how easily elements could bond and create a potentially harmful compound or damage another element and ruin an ecosystem. For example, when salts leak into lakes or streams it increases the salt amount in the water so no fish or other animals can live there or rely on that as a source of water. You can also use your knowledge of Chemistry to see how the chemicals in the air cause smog, acid rain, and global warming. Since hydrogen is found almost anywhere on earth, it can bond with every element, but the noble gasses. Also, you can use Chemistry to see how industry makes their products and how they are designed to suit the consumers needs. For example, air fresheners and cleaning products are all made from chemicals by a factory. In conclusion, learning about Chemistry helps us see the effects of industry better.

Current Events: DNA Uncovers One of the World's Rarest Birds
DNA Uncovers One of the World's Rarest Birds
November 23, 2010
University of Adelaide

http://www.sciencedaily.com/releases/2010/11/101123102403.htm
Researchers at the University of Adelaide and the Australian Wildlife Conservancy have recently discovered the difference between Western and Eastern Ground Parrots. Scientists tested samples of DNA (deoxyribonucleic acid) from many samples, some were over 160 years old and found many genetic traits that differed between the two different types of ground parrots. This therefore proves that since their are two different types of ground parrots, one is endangered. The Western Ground Parrots are one of the rarest birds in the world, and according to researchers, there are only about 110 left in the wild. Since most of them live in national parks, scientists say that a wildfire or the introduction of a new predator such as a cat, could push this species to extinction. Overall, this newly discovered species is already in danger of extinction.
This is an important discovery because it could possibly lead to the the discovery of other new species. If we use the technology we could be able to tell the difference between similar animals and could help teach us a lot about our planet. Also, this could help classify the animal kingdom.In addition, if scientists can run theses kinds of tests on plants, they could potentially find cures for diseases by finding certain chemicals. This can also be used to improve agriculture. For instance if a certain species has a trait that others do not, it can be singled out and used to improve plant growth. Western Ground Parrots are currently endangered, if the scientists had done a study a couple years later, the most likely wouldn't have been able to find any specie in the wild. This also shows how we should take care of the environment and preserve our national forests.
All in all, I found this article very interesting and learned a lot about how even the slightest change in an animal or plants genetic code could make it an entirely different species. I found the section about how they tested the DNA of different types of birds especially fascinating and would like to know more about it. This article was written by the University of Adelaid, with information from the Australian Wildlife Concervancy, so you know all of the information is correct and up to date. I found this article very interesting and would like to know more about how the tested the birds DNA.
Overall, this article was very interesting and taught me a lot about how even the slightest change in a group of animals genetics can make it a different specie. This new technology could also lead to the discovery of new species and teach us a lot more about the environment. Also, this new information could help society grow better crops, develop new medicines, and finding new information about the animal kingdom. For hundreds of years nobody knew there was a difference between eastern and western ground parrots, but scientists discovered that they were not the same. In conclusion, Western Ground Parrots are endangered and in need of help, and new technologies make it possible to tell the difference between closely related species.

Current Event: Genes help plants grow faster
Gene Discovery Suggests way to Engineer Fast--Growing Plants
Science Daily
November 11, 2010
http://www.sciencedaily.com/releases/2010/11/101111121626.htm
Scientists and Duke University have recently discovered how to make perennial (last all year) grasses grow faster. They studied the genes of several plants to they could study the UPB1 gene, which causes cells to become more active when cells divide and cause plants to mature. The Scientists then removed and manipulated the gene so plants would grow faster and have thicker roots . Before they this perennial grasses took two to three years they grow, but this discovery could lead to faster farming that would be more convenient. UPB1 is found in plants such as switchgrass and miscantus, which are used in biofules. Also, removing the UPB1 helps plants convert more Carbon Dioxide into Oxygen, which would help the environment. Overall, speeding up plant growth could help manufacture biofules and help the environment.
If Scientists manipulate the genes of plants it could leave a very positive effect on both society and the environment. First of all, this gene helps plants grow in shorter times. This would help farmers grow more crops to feed the growing population. Secondly, manipulating this gene causes plants to be able to convert more Carbon Dioxide into Oxygen, therefore helping us get rid of greenhouse gasses. Also, removing the UPB1 can help grow biofules faster. There are however some negative effects this discovery could have. For example, if large, industrial farming companies get a hold of this soon, they could rapidly produce crops, running small farms out of business. Also, scientists are still unsure of all the negative effects removing this gene could have. All in all, manipulating the UPB1 gene could have both positive, and negative effects on the environment and society.
Overall, I found this article very interesting. I was especially interested in how they remove the gene and wish they had gone into more detail about it. I am also confused about how removing this gene will help the plant grow faster. Also, how is do they remove the gene in all of the plants, do they have to do it individually or only to a few plants? This article was based on findings at Duke University, as well as published in a scientific magazine, so the information is valid and accurate. I found this article to be very interesting, but I wish they had gone into more detail about some information.
In my opinion, this discovery could be very useful and help the world in many ways. While reading this I learned how removing a one gene could change how a plant looks, or grows. Also, I learned that biofuels take a long time to grow,but last for a very long time. When scientists prefect this new technology it could help produce more food and fuel, as well as get rid of more harmful carbon dioxide. Also, I think removing the UPB1 gene should be heavily tested to make sure that there are no hazards reactions or mutations. In conclusion, manipulating the UPB1 gene could be very useful in industry and farming, as well as help the environment

Current Event: Invisibility Cloak
"Invisibility Cloak Closer with flexible 'Metamaterial'"
Jason Palmer
BBC News
November 4, 2010
http://www.bbc.co.uk/news/science-environment-11686303
Scientists in the United Kingdom have developed a new flexible film they call a "metamaterial" which is a big step towards creating an invisibility cloak. The new material manipulates the light beams and therefore causes the object to appear invisible. Metamaterials interrupt and channel light causing light waves to bounce around. Besides invisibility cloaks, this material can be used for camera and contact lenses since they divert light. However, this material is highly sensitive to motion and manipulation so scientists have a long way to go until perfecting metamaterials. Overall, metamaterials are a new technology that could one day lead to creating an invisbility cloak like the ones in stories.
Metamaterials can help society in many ways. For example, this flexible film can be used in contact lenses which help people see. Also, metamaterial can be used in cameras which could lead to clearer more detailed images. In the future this discovery could lead to the invention of an invisibility cloak which would have a major impact on society. An invisibility cloak would be useful for the military and could be used for spying. Also, invisibility cloaks would be in high demand for consumers and therefore would be good for industry. All in all, the invention of metamaterials could have important effects on society.
Overall, I found this article very interesting and learned a lot about how diverting light can make something appear invisible. However, I am still confused about how metamaterials can turn something invisible by only manipulating the light. Also, I think it is fascinating how using metamaterials can help people who have eyesight problems see better by blocking out some of the light. I would like to know more about how they made it bend while still reflecting light. Overall, I really enjoyed reading this article and found it very interesting to learn about how they have created new technologies that could eventually lead to inventing an actual invisibility cloak.
I found this article very interesting and entertaining because I have read many books with invisibility cloaks in them and was curious to learn more about the technologies being used to create them. By reading this article I learned that bouncing light particles are used to change an objects image and create an illusion. Also, I learned that if you scramble light that creates a better image that you can see clearer while taking a picture or wearing contact lenses. In conclusion, I think this is a very important discovery that could help society in many ways.

Firework Video Reflection
In this video I learned a lot about how fireworks are made and what chemicals are used in them. For example copper oxide (CuO), strontium chloride(SrCl2), sodium silcate (Na2SiO3), calcium nitrate (Ca(NO3)2), barium actate (Ba(C2H3O)2), Sulfer (S), and potassium nitrate(KNO3) are some of the chemicals used to create these fantastic displays.Since these chemicals are very dangerous, you should always wear safety goggles and use a location fuse so you can set reactions off from further away when you are working with especially dangerous chemicals. The capsules used to set of fireworks are especially designed so that when you light the fuse the fire will ignite the gun powder and then that sets off the delay fuse which lights some more black powder in the middle of the capsule, causing whatever chemicals you are using to create a fireworks display. When you are making a firework you need two things, an oxidizer like Strontium Nitrate and a fuel like charcoal or aluminum powder.The other chemicals used in fireworks are special compounds that cause a bright flame that you see when a firework goes off. The oxidizer and the fuel react to create heat which sets off the explosion. Fireworks are an example of a physical reaction. You can tell this because the chemicals are changing their molecular structure when they are exposed to fire and heat. Overall, this video was very interesting and I learned a lot about how fireworks are made and what chemicals are used in them.

| Kepler |
The photographs and data could have a very big impact on the scientific community.Fist, the photographs of stars could help us understand the universe and lead to important advancements in physics. Another possible discovery would be if the Kepler found life on other planets or planets that humans could live on. If they found alien life if could lead to advanced technology and would add to our understanding of plants, animals, chemistry, and many more areas of science. Also, if the Kepler found a planet that could be inhabited by humans then it could save us if there was some sort of disaster like in 5 million years when the sun expands.Overall, the Kepler could find information that would completely change our understanding of the universe.
This article was written by Iowa State University so all of the information is correct. In general most of the information made sense and most of the concepts were explained very well. One thing I learned was about the Theory of Relativity and what binary star systems were.I however did not completely understand the concept of star quakes and how scientists study them. I would also like to know how the Kepler is sending back information to the scientists when it is billions of miles away. Overall, this artical had lots of interesting information.
This artical was fascinating and taught me a lot about the stars and how measuring the brightness of a star could help scientists figure out if the planet could substain life. Before reading this artical I thought it was impossible for stars to orbit around each other, but now I know that it is possible. I agree with the authors that Kepler could lead to great scientific discoveries and completely change our understanding of the universe. I chose this article because i thought the cocept of using a photometer to determine the temperatures of the planets sounded very interesting because it could help discover life on other planets. In conclusion the Kepler uses new technology to help us learn more about the universe.

Toxic Spill in Hungary
Hungary battles to stem Torrent of Toxic Sludge
BBC news
http://www.bbc.co.uk/news/world-europe-11475361
On October 5, 2010 toxic sludge spilled out of an aluminum plant in Hungary. According to experts 600,000 to 700,000 cubic meters of the sludge leaked out of the plant. The heavy rainfall is suspected to have caused the plant to overflow. This event has killed at least four, has injured 120, and has effected 7,000. The chemicals consist of water and heavy metals. Also 90 people have been sent to the hospital with serious chemical burns from the chemicals in the sludge. So far three countries have declared emergency. In the town where the spill took place the chemical waste is said to be two meters deep. Right now, six emergency teams along with police officers and soldiers are working hard to get rid of this hazardous waste. There have been alerts for the Marcal and Torna rivers and people are trying to keep the sludge from contaminated the Raba and Danube rivers. Experts have predicted that the spill will take at least eighteen months to clean up.

Brain Cell Communication: Why its so fast
Science Daily
http://www.sciencedaily.com/releases/2010/09/100921111000.htm
Scientist from the universities of Copenhagen have been studying brain cell communication. When you nerve cells transmit signals slowly this can lead to mental disorders like schizophrenia, Parkinson's Disease and attention-deficit hyperactivity disorder. The scientists have discovered how brain cells transmit signals and interacts with each other. The cells use small neurotransmitters that pass on molecular messages. The scientists have also discovered that cells with only one set of SNARE (linking bridges) can connect with each other, but it takes a lot longer. According to Professor Jakob Balsev Sørensen they are going to study why some reactions are slower and if our cells do that on purpose and what kind of affect it has.
This is a very important discovery that could have a great influence in medical history. If they can figure out how to add more linking bridges in cells than that could help cure some genetic diseases and sharpen peoples reflexes. This discovery could be used in the military to help train soldiers to have quicker reflexes so they can react faster if they are in danger. Lots of genetic problems cause difficulties for many people all over the world, this new technology could help cure them.Right now these experiments are in the early stages, so it will take a while to develop the technology, but when they do it could have a very big affect on society and medicine.
This article was based on studies at the Universities of Copenhagen, Göttingen and Amsterdam. I learned that the nerve cells have could several SNARE bridges in them that transport biochemicals to the bran using neurotransmitters. While this article was very interesting I'm still not sure what SNARE stands for, I know they are little "bridges" that the information is sent through. I also learned that the number of bridges influence how fast cells can fuse and send signals. Also, can you insert the connector bridges into other cells, or is that impossible? Overall this was a very interesting article with lots of fascination information.
I chose this article because I am really interested in genetics and the nervous system as well as recent developments in medicine. I never knew that some cells had multiple bridges to other cells and that that causes the speed of the reaction. I agree with the author, this discovery has a lot of potential. If it is studied enough it could possibly increase our understanding of the nervous system and help cure many diseases. In conclusion, this discovery could help save lives by curing diseases.

Bioplastics
Bioplastics are a different variation of plastic, that are more environmentally friendly than regular plastics. Instead of using crude oil to create plastic, bioplastics use corn and other organic materials to create plastics. Also, Bioplastics are combustable, which means they can decompose instead of slowly rotting in a landfill. One example of a Bioplastic being used today is in Sun Chip bags. Theses are biodegradable bags can decompose and therefore not cause any pollution and is made completely of bioplastic.These However there are many problems with the manufacturing of bioplastics. In order to grow the organic plants needed for green plastics farms use a lot pesticides and crude oil to power the tractors and other equipment. Also, the factories use a lot of electricity which is made using crude oil. Another concern is taking up land to farm products for plastics could effect the world food supply, possibly causing a worldwide food shortage and could harm the rainforests because of cutting down trees and destroying land. You cannot combine different types of plastics because their melting points are different and the plastics are a lot less strong and break easily. Polyactic acid is a type of bioplastic that is made by combining Lactic acid oligemers which are turned into Lactide and become Polyactic acid. To create normal plastic you combine diffrent Monomers for RO2H2 and create Polymers that release H2O (water) when they combine. When you create Bioplastic CO2 (carbon dioxide) is released. This video connects to Blue Gold because it shows the importance of keeping our environment clean and using new technology to stop polluting the water by stopping our dependence on mining for crude oil. Overall bioplastics show promise for helping create a more environmentaly friendly industry.

Atoms Video
http://www.101science.com/Chemistry.htm#Chemicals_and_Interactions
Overall I found this video very informative. Atoms don't orbit around the nucleus, they have orbitals. This means that electrons can be found anywhere in an atom and there is just the probability of where electrons can be. Atoms can have diffrent shapes depending on the number of electrons and the charge of an electron is stronger the further away it is from the nucleus. One thing I found shocking is the fact that 99.99% of atoms are just free vacuum space. This means that even solids aren't completely solid since only 0.01% of atoms take up space. Also in an atom the number of protons can change, but it will still remain the same element. These are called isotopes, which are diffrent variations of an element. The atomic weight is the average weight of the isotopes. Also, one proton or neutron is equel to 1 atomic mass unit (AMU) which is used to measure the atomic weight. One proton is equel to 1836 electrons. In conclusion this video was very interesting and had a lot of important information.

Current Events: Firefly Stem Cells
"Firefly" Stem Cells may help Repair Damaged Hearts
University of Central Florida
Science Daily
http://www.sciencedaily.com/releases/2010/09/100928111122.htm
"Firefly" stems cells were created to help doctors monitor the activity of the stem cells. According to Steve Ebert, the scientist who engineered the firefly cells, they got their name because they grow brighter and brighter if they are working. These stem cells are currently being used to help heal hearts. They are very helpful because the doctor doesn't have to cut open the chest to monitor the activity. Instead you can tell how the cells are working by using a special light. Overall Firefly stem cells could help save many lives and be an important part of stem cell research.
In a way this connects with what we are studying in class. The scientists who developed firefly stem cells combined many chemicals to make them glow brighter under a light without harming the patient. Firefly stem cell could have a very important roll in modern science. If this works, then more people's lives will be saved because stem cells could help heal organs. Scientists still don't know why stem cells morph into organs, but because of this new technology they can now watch the firefly cells in action so they can better understand how they work. Overall firefly stem cells could help save many lives.
This article was written by the University of Central Florida so the information is valid. While the article is very interesting it still leaves you with a few questions. How do they monitor the stem cell without cutting the person open? Are they able to see through their skin or do they have to use a MRI or X-ray? Also it is very possible this new discovery could have some side affects, but so far they have not shown. Could Firefly stem cells also be used to heal diseases or other organs? Overall Firefly stem cells are a new technology that is still being developed and studied.
I chose this article because I find stem cells to be very interesting and could help save many live. One day stem cells could help sick patients grow a new organ, repair damaged tissues, or even grow a new joint. I agree with the authors, I think Firefly stem cell could be a major discovery and make it possible to monitor and study the effect stem cells have on human beings. Overall, firefly stem cells could help increase our understanding of stem cells and be an important advancement in the medical industry.

"Firefly" stems cells were created to help doctors monitor the activity of the stem cells. According to Steve Ebert, the scientist who engineered the firefly cells, they got their name because they grow brighter and brighter if they are working. These stem cells are currently being used to help heal hearts. They are very helpful because the doctor doesn't have to cut open the chest to monitor the activity. Instead you can tell how the cells are working by using a special light. Overall Firefly stem cells could help save many lives and be an important part of stem cell research.

Facts about Water
20 Things you don't know about water by Rebecca Coffeyhttp://discovermagazine.com/2010/may/20-things-you-didn.t-know-about-water
1.) I found it really interesting that scientists found water under the ocean floor and think there may be more water under the oceans than in it. This could help humans obtain more water if the water turns out to be fresh. Also, there could be new organisms in the water under the ocean and could help make important scientific discoveries and further our understanding of the environment.
2.) I didn't know that watering plants during they day could actually harm them. Water droplets on the leaves focus the suns rays and cause the plants to burn. This knowledge could help farmers grow more crops and therefore help produce more food for the worlds population.
3.) Some Scientists think comets brought the first water to the solar system. This could mean that 4.5 billion there were other life forms living on the comets. Also, this information implies that it is very possible for other life to exist in the universe.
4.) The water recovery system on the international space station could help us conserve water. If you recycle water, it would help conserve all of the water we have, as well as decreasing the amount of pollution. Also, we wouldn't wast nearly as much water as we do now if we reused it. Although it may seem disgusting, recycling water could help save the planet.
5.) I was shocked to read that before 2009 it was not against the law to sell bottled water that contained ecoli. Until a year ago the companies that bottle and sell water did not bother checking for the deadly disease. It is very important to monitor the cleanliness of our water.
Information from other websites.
1.) Water dissolves more substances than any other liquid. This means that there are lost of chemicals nutrients, and minerals in water. This can be either good or bad. It there is a perfect amount of nutrients in water than ecosystems can thrive. On the otherhand, if the water has too many nutrients this can cause serious environmental problems such as alge blooms. Chemicals from factories or farms also can harm ecosystems and leave negetive effects on our environment. (20 interesting and useful water facts. http://www.allaboutwater.org/water-facts.html)
2.) On January 1, 2013 the Safe Drinking Water Act (SDWA) will be enforced in Canada. This act assures Canadian citizens that their drinking water will be clean and disease free. It is very important because humans must drink water to survive, but if the water is polluted and carrys diseases than it could end up killing someone. (Safe Drinking Water Act, 2002 http://www.e-laws.gov.on.ca/html/statutes/english/elaws_statutes_02s32_e.htm)
3.) On March 22 the world celebrates world water day. This holiday was created after the 1992 United Nations Conference on Environment and Development. World water day is important because it creates awareness of all of the pollution and other problems that affect water. If the world knew more about what may happen if we don't stop wasting water they would make more of an effort to help concerve and protect our worlds water sources. (World Water Day Help Make a Diffrence http://www.worldwaterday.org/page/135)
4.) According to the United Nations in 2025 forty-eight nations will face scarce supplies of water. This is not good, right now many people don't even have enough water. If we continue polluting water with hazardus chemicals and waste the world could face a water shortage. Overall we need to save water now to help the world survive. (Water Facts http://water.org/learn-about-the-water-crisis/facts/)
5.) The earhs atmosphere contains about 13,000 cube killometers of water. This water can be used to create humidity and clouds. This proves that not all water is found on or in the ground, but also in the air. If we continue releasing greenhouse gasses this pollutes the air and causes acid rain. (UN Water Statistics Graphs and Maps http://www.unwater.org/statistics_res.html)
Overall water is a precious and usefull resource and should not be wasted.

Current Events: Dry Water
Dry Water could make a big Splash Commercially
by the American Chemical Society
sciencedaily.com
According to The American Chemical Society dry water could help stop global warming, make an alternative energy source, transport chemicals, and be used in industry. According to Dr. Andrew Cooper who is in charge of new research dry water is a powder that is 95% water and 2% silica and it got its name because even though it is mostly made up of water the substance is a dry powder. Scientists have discovered that dry water absorbers more carbon dioxided, which is one of the main causes of global warming. Dry water can also be used to speed up chemical reactions, which would help produce consumer goods faster. Also, dry water is ideal for transporting chemicals such as carbon dioxide and methane. Overall scientists have discovered many new uses for dry water.
There are many ways dry water connects to what we are studying in class. Dry water can be used to speed up chemical reactions and remove greenhouse gasses from the ozone, which would affect the environment and aquatic ecosystems. Also, dry water is a chemical compound that can prevent gasses from escaping if they are contained in dry water. Dry water affects society because it is making if easier and faster for facotries to manufacture items and transport hazardus chemicals. Also, dry water can help prevent global warming. This would be a great help to society because there wouldn't be as many tropical storms and unusual weather patters, as well as help preventing droughts. All in all, I think dry water is a very usefull substance.
Event though this artical was very interesting I still have a few questions about dry water. I still don't understand how dry water can be used to contain chemicals. Do they add water to the powder to make it sturdy ot add some other chemicals so it can contain gasses without releasing any? Are their any negetive qualities of dry water and are their certin elements they would react with? Scientists at the American Chemical Society are still hard at work learning about all of the qualities of dry water.
I chose to read about dry water because it sounded interesting and was a new way of fighting global warming. The world is struggeling against greenhouse gasses, and dry water could help contain them and help heal the ozone. I learned a lot about how new chemicals could be used in industry and help saving the world and that dry water is a powder, even though it is 95% solid. It was interesting how dry water used to be used in cosmetics and now it is being used to contain chemicals and speed up reactions. Overall dry water is a very intersting substance that could help save the world.

Water
Ohio has many rivers and lakes including Lake Erie and the Ohio river. In total Ohio has 1,050 dams, many are along the Ohio river which flows through Ohio, West Virginia,Indiana, Kentucky Illinois, and Pennsylvania. A major source of water is the O'Shaughnessy reservoir and is also used to produce electricity. There are many industries that dispose of waste in the Ohio river. Most of the pollution is caused by animal waste and chemicals from farms contaminating the water. Lake Erie borders northern Ohio and there are many smaller lakes all over Ohio as well as a lot of water underground. All of the runoff drains into the Ohio River Basin.To get water to the houses the water is first cleaned then sent through pipes to the houses. Overall Ohio has many water resources including lakes and rivers.

You can tell this is chemical reaction because the color changes and the chemicals
Watching the videos I have noticed that the reactions stop after awhile when some of chemicals have spilled over the edge. During the reactions the color changes and there is smoke. In order to guess what chemicals are mixed you should see if it expoded or there was any smoke.

Todays Lesson
Though todays lesson was confusing, I now understand it. You combine atoms to complete the number in the outermost ring and then you have a compound. I'm still a little confused about the rules for combing atoms (1,2,
-1,-2 etc.).
