I believe that the second and the third charts are very similar. They both have the same structure as a graph. The first image is not like the others. They all give the same information, The Classification of Matter. The second and third graph are “tree” graphs while the first one is not.

The graphic that I like the most would be the second graph because its very simple but also very informational at the same time. The second graphic is very easy to understand and easy to read. It also, classifies matter.

While experimenting for separation of matter I have discovered that there are many different dyes and lakes in the candy coating of M&M’s, and Skittles. I learned that if you put the dye from the candy onto a special paper and then submerse the very bottom of the paper into a 1% salt solution that it will climb up the paper and reveal what color that is in the dye of the candy. This was very interesting to learn.

An area that measurement is important to me would be in baseball. Measurement has a lot to do with baseball, such as, the bats must be a certain depending on how long your bat is. The bases have to be exactly ninety feet apart, and the pitchers mound must be sixty feet six inches away from the back part of home plate. Also, there are different sized gloves that you by depending on which position that you play, an example would be if your an outfielder you will have a larger glove than an infielder would.

Austin,
I can tell you are a student of the game of baseball. Good! MW


After reading the article on redefining the kilogram,I have learned that there are seven base units of SI measurement. Before reading this article I have only heard of two of the seven units of SI measurement. The two that i knew before were the kilogram and the meter. There were also things that i didn't understand such as, you are not allowed to touch it now%Proxy-Connection: keep-alive Cache-Control: max-age=0 oxy-Connection: keep-alive Cache-Control: max-age=0 roxy-Connection: keep-alive Cache-Control: max-age=0 Proxy-Connection: keep-alive Cache-Control: max-age=0 Proxy-Connection: keep-alive Cache-Control: max-age=0 Proxy-Connection: keep-alive Cache-Control: max-age=0 ven though they have many, many copies of%2Proxy-Connection: keep-alive Cache-Control: max-age=0 he kilogram. I'm a little confused on why they have it encased in two jars, I'm guessing to keep it from contamination.

Austin,
I think it is safe to say you are correct on the contamination thing. MW


After reading the article on the airline security, I have now realized that, that job is an intense and a very important job. That job is much more diffilcult than i have expected. I believe that it is very interesting on how people try to smuggle bombs onto planes. But, after every successful attempt on their part and even failed attempts, the TSA gets a plethera of information on how to be able to stop future attempts on bombs being brought onto aircrafts.

Austin, Good thoughts. The word is spelled plethora - but good word choice

One thing that I found interesting on the Mole Day site was that the reason they started this was to get more people interested in chemistry. I also think that it is cool how they have a mole person of the year. I think that is a great way to get people to visit their site and get people to register and read their information on the website. I also enjoyed looking at the pictures of the mole theme for each year from 2001-2009.

Austin,
Did you find anything scientific?? 4 stars. MW

One thing that I have found interesting from this article would be that when dust of any kind brakes down small enough it should be considered combustible. I also found that one eighth of an inch of dust is considered combustible. Also, that some work shops or plants that have a half of an inch of dust! That's just amazing that no one would recognize that and clean it up. The dust won't catch fire or combust because there is no oxygen mixed in with it but when one explosion erupts then all the dust is thrown into the air and just like the lycopodium power when Mr. Williams blew it through the funnel it combusted in a big fire ball.

This article on Sulfur Hexafluoride is very interesting, if you breathe it in it has the opposite effect on you as helium. Helium as you probably know makes your voice high pitched such as, a chipmunk. But Sulfur HexaFluoride makes your voice very low. I learned that if you breathe in one of the two and then most people laugh and do it again you are actually suffocating yourself because you aren't replenishing your body with oxygen. Your getting rid of the bad carbon dioxide but not getting any oxygen.

Austin,
OK. Looks good. MW

This article on Motion detectors was very interesting in learning the ways that they work. The three ways that motion detectors can work are, one is a heat sensor, it picks up infared radiation that is given off by heat. For example, human body is around 37 degrees C but the skin is close to 34 degrees C and that gives off IR wavelengths of 9-10 micrometers. Another way Motion Detectors work is how a bat is able to fly with such bad eye-sight. it sends out signals and it reads the return signal patterns. When someone of something walks or moves in front of the detector it will recognize that it is not the normal reflection pattern as normal and therefore know that something is infront of it. Lastly, some detectors use a light source. It is placed across from the detector and when something moves infront of it the light signal then becomes blocked and then it recognizes that something is there. This article goes to show that chemistry is prevalent in everything in our everyday lives nad that it is important. Motion Detectors are cool contraptions and have a very interesting background on how they work.

Austin,
Good job! Very thorough! BTW your famous now! Easy theft in the lower left.;) MW
