The chemistry of materials has shaped our past past because it has brought to where we are today in many different categories. During WWII chemistry created the nuclear bomb, had that not happened who knows what life today would be like. chemistry helped scientist find the right materials to put on the space ship to send the first man up into space, a huge moment in our history. In the Present day we have been able to make medicines that help people get over illnesses some that at one time were deadly. “How does the structure of matter on the atomic, molecular, microscopic and macroscopic levels determine a material’s properties?" the structure of matter always determines the materials properties. on the atomic level the way the way the atoms are lined up and put together determines if the material is a solid liquid or gas. the closer the atoms are together the harder they are. The electrons are swapped in covalent and ionic bonds between two atoms affect the two atoms and bring them together to make a this is the same for the other structures to, the way they are a- lined affects its properties. with polymers the way the molecules hook up together affects its strength, if you have a chain-linked polymer the longer the chain is the stronger it gets. Energy and Place and essential Questions Opening and closing statement Joint Scientific Statement Link to Debate Video Link to humanities page My partner and I argued against the motion for Natural Gas and oil because of the environmental and social risks that it brings. My original opinion was that i didn't really have a problem with hydraulic Fracturing and using natural gas. After the debate i see that there are still many flaws in this method of energy. I think that it is good that our country is more independent for energy but there are a lot of risks that come with it as well. I came to this opinion because i was moved by the amount of crime and violence that happened when workers for the drill site started to show up. i think the strongest piece of evidence that i used for the debate was the methane emissions from natural gas. It helped me explain that there were still problems with natural gas even though there wasn't any CO_2 emissions. I would like to do more research for the ground water contamination issue. it seems like it would be really hard for there to be a leak in the pipe because it is so far underground. I argued a position that i was not really in agreement with. It was hard for me to find evidence and a good argument because i didn't know how well i could argue it if i don't agree with it. it did help me see both sides though so i am glad I was given this role. In humanities my sense of place made me think of how hard it would be if there was a sudden increase of people that came to work at a drill site. after i read about all the crime and violence in these areas i think it would be really hard to accept the change in culture and environment. I think i had a strong argument, I did a lot of research and built up what i think was a really good and refined argument. however i was really nervous during the debate and stammered a bit during my presentation. this made my argument sound a little weak and not as confident as much as i would have liked. Our Fact check. Fact 1: Methane has seen as increase at drilling sites. it is believed that methane is escaping through tiny leaks in the pipes. many drill sites are burning the methane off that's why there are torches on the top of these drills. Fact 2: Crime has seen an increase at these drill sites because of the people that come to work. police departments have seen as much as 8x the amount of crime in three years. Opposing Fact check. Fact 3: natural gas is a cleaner way of getting energy then Coal. natural gas has about 30% less emissions of CO_2 then coal. Fact 4: Ground contamination cannot occur from leaks in the pipes that are underground. the area where the drills collect the gas is about a mile and a half underground or about five emperor state buildings. |
