Mr. Williams I have no idea what happened to my page. It was there one minute and gone the next. I just don't know. 8/27/09- I believe that the first graph is most beneficial to me for various reasons. First off, the pictures in the first graph show me the differences between elements, compounds, and solutions at the particle level. Secondly, I think that the first graph will be more beneficial down the road but the other two graphs are helpful also. The two tables will be helpful when choosing mixtures and pure substances. I would use all three tables but would prefer the first graph over all three. Andrew Guinan

8/28/09- Today when watching the movie I found the refining of crude oil to be very interesting. Seeing that I have used all types of fuels ranging from jet fuel to diesel fuel it was useful to see how everything was made. I was blown away to see that all these different things were made from plain crude oil. I also saw the connection between are small lab and the mass production of oil into gas, diesel, jet fuel and a number of other things. Previously I thought that these fossil fuels were mixed together with a number of flammable liquids to produce a final solution but I was incorrect in my assumption. Andrew Guinan

Andrew, Isn't it a good feeling to clarify your knowledge on a topic? MW MW, Definitely! Andrew

8/31/09- Measurement is used everyday in my life in various ways. I use it when reading my fuel gauge on my mower or truck. This becomes very useful and if I were to measure incorrectly I could run out of gas and be in a big pickle. I also use measurement when adding ingredients when I do any kind of baking. If my ingredients aren't correct I could have a bad tasting result and have to throw out my cake or whatever food I attempted to make. I also use measurement when I am building or fixing anything. If my measurements are off it could collapse or fall apart and my hard work would be all lost. Measurement is definitly a big part and important part of my%2Proxy-Connection: keep-alive Cache-Control: max-age=0 ife. Andrew Guinan

9/7/09- This article was very interesting to me for a number of reasons. I thought that it was very interesting that the there is one piece of metal that is the basis for all measurements of a kg. I also thought that is was interesting how there is a replica in a vault in Maryland also. I do wonder why the replica is kept in Maryland? Why not somewhere else? I wonder the same for the original piece in Paris. Why not somewhere else? Overall I thought that the article was both interesting and filled with information. I do think that we as a class should talk about why the replica lost weight over time. Andrew Guinan

Andrew, Good thoughts! Not sure about the page. Hmm. Anyway I like your idea of having a classroom discussion. MW

9/14/09- This article was particularly interesting to me because I was just recently traveling via plane and I know how long the line was to go through security. I also know that the machines that are being used are state of the art and they are highly sensitive. Even the smallest piece of metal can set off the machine and then it takes even longer! I know this is for our safety and I greatly appreciate it. I also think that it is amazing and terrible that terrorists would take household chemicals and try to make bombs out of them! This is a chemical reaction that we study in class and people use to try to harm others. This article was very beneficial in understanding how chemicals and compounds we use everyday in class can result in dramatic measures. Andrew Guinan

10/6/09 - The Mole website to me was very interesting for many reasons. It helped me to understand that the Mole Formula is very important in Chemistry. I also didn't know that Mole Day officially starts at 6:02 AM and ends at 6:02 PM. Mole Day starts and ends at these times because of the formula 6.02X10 to the 23rd power. And then they get the actual Mole Day from the 10 to the 23rd power in the formula. I also learned that Mole Day was created to help bring interest into Chemistry. Finally I learned that Mole was created by Amadeo Avogadro and that he only received credit for it until after his death in 1858. I wasn't aware that Mole Day was so popular!!! I didn't even know that there was a Mole Day till Mr Williams Honors Chemistry Class!!!

Andrew,

No one suspects mole day!!! :) MW

11/7/09 - This article was very interesting to me in a series of ways. First, I was drawn into it because of its very distinct topic. I mean how could you get an explosion out of a factory that manufactures sugar? This is very weird but interesting. I learned that old sugar that has been laying around for a while can be ignited from static electricity or a spark. This is pretty sad for the factory and the dead workers, but cool on the chemistry side of it. I did not know that when ignited a fire ball moves and tears through the factory with no one to stop it or stand in its way!! I also found out that everything in these factory's that were used to produce sugar are now helping to destroy it like conveyor belts, transfer lines, and ducts! I learned that the dust gets stirred up, thrown into the air, and it reacts with the oxygen in the air and kaboom! A fireball appears. Finally, Stoichiometry is important to these reactions because it finds out how much of a substance is reactive to form an explosion. - Andrew Guinan

12/4/09 - I loved this article on Sulfur Hexaflouride and its affects on our body. I mean by way of the vocal chords. If you breath it in it lowers your voice and you sound like a creeper! I also found Sulfur Hexaflouride interesting because in class you talked about a heavy gas like Sulfur Hexaflouride making a ballon expand over time instead of ballon deflating if would contain a lighter gas like helium. I also found it interesting how the two elements separate are dangerous, but when they are put together they form a stable bond that compares to a gas like helium. I have never tried to inhale Sulfur Hexaflouride but I have inhaled Helium and it is a very funny gas to play with. I'm sure Sulfur Hexaflouride would be the same but I think it would be a little strange feeling when it stays in your lungs for a while and you have to breath it out deeply. -Andrew Guinan

Andrew, Solid post! Funny too. :) MW

12/15/09 - In this article about motion sensors I learned that their are many different types of motion detectors and that they each work in different ways. Motion sensors can use radio waves that travel from the main unit to a sensor on the ground and when something comes between the unit and the sensor, the light turns on. Another type uses infrared sensors that sense the when something moves in the dark and it triggers the light to turn on. The third kind of motion detector uses a laser and when an object passes through the laser it tells the light to turn on. Motion detectors in my mind are just a hazardous and annoying thing. Not because I sneak out, its because any little movement at night sets it off and it becomes annoying. -Andrew

Andrew, I agree! They are a pain... especially on an outside light! MW
