Kyler Jelonek August 26, 2009 Graphic Orgnizers: All of the three graphic organizers display good and useful information. All would be useful for different types of things. The first one is good because it shows pictures of what the particles look like and it also gives information about it. The second one is good because it makes it easier to remember how to categorize each type. It also shows that the are all matter. Although the first two are good, I like the third graphic organizer the best. One reason for this is the fact that it is like the second one but goes even farther (gives examples of each). I also like it because it's easy to read and very helpful to me in remembering the differences and classifications.

August 29, 2009 Separation of Matter: I found the separation of matter and especially crude oil to be actually quite interesting. It was neat to see how different things can be made depending on the number of atoms and how high the vapor rises. I learned a lot from this topic such as how matter is put together to make more useful things. During our chromatography lab I also learned things. First of all I figured out why there are numbers after the colors in the ingredients section of food. This (along with the lab last year) helped me to understand what chromatography is and how it would be useful. It is very interesting to figure out what each thing is made out of. Filtering separates solids from liquids and distilation separates liquids by boiling.

August 31, 2009 Measurements: Measurement is important to my life in many ways. I use SI unit more than the metric system but both have importance though. One of the major things that I use measurement for is when I re-arange my room and need to figure out if a certain piece of furniture fits somewhere. Another major thing that I use measurement for is when I cook and need to know how much of an ingredient to put in (milk, choc. chips, or something else). One other thing in my life that realizes on measurements is when I tryProxy-Connection: keep-alive Cache-Control: max-age=0 0on clothes or shoes. It doesn't use Proxy-Connection: keep-alive Cache-Control: max-age=0 et, inches, or anything like that but size is still very important because if it doesn't fit then it could be too tight and pinch your neck or something. Without measurements, day to day life would be very difficult. Also, if measurements were incorrect, I would have moved the furniture for nothing, made bad tasting food (unless I get lucky), or have a sore neck from clothes being too tight. All of which would not make me very happy. Kyler

September 4, 2009 Rediefining the Kilogram: After reading the article, I found a few major things to be interesting. The first is that the kilogram is the only unit that is still defined by a physical artifact. I find that interesting, not because I feel there should be more, but because they have not yet changed the way it is defined as well. Another interesting point that I read in the article is that so many units can be converted to each other and how the numbers are equal to numbers in other units (it's kind of hard to explain). FOr example, Avogadro's constant is equal to 6.0221418 X 10^23, which can also be converted to Catoms. One final thing that I found to be interesting in the article is that so much is known about measurements and weight I find it incredible that people can be so smart as to find a way to calculate all of this and invent new and better ways to do things in the fields of science and mathematics. Although this article was a bit over my head, I still found what I could understand to be very interesting.

Good remarks Kyler! MW

September 14, 2009 Airport Security The article that I have just finished reading is very interesting. It described the process of protecting planes, passengers, and crew members by haveing them go through security checkpoints which include metal detectors and machines that you put your luggage though to be xrayed fom bombs, knives, etc. The carryon bag checking machine is quite intesting. The machine scans the densities of all of your carry on items. Any material that has a near or exact density of explosives show up red on the computer screen. This process relates to our class in many ways, especially in dealing with density. In our class, we are learnig how to calulate density when you know mass and volume, calculate volume when you know desity and mass, etc. That is how airport security scanning relates to this class.This article was very interesting to me, I even read the other two pages.

October 7, 2009, Mole Day: After visiting this interesting and semi-humorous website I learned quite a few interesting facts about the mole of chemistry. I learned that it was discovered by a chemist and physics professor named Avagadro. He realized that equal volumes of gas contain the same number of molecules. The mole is very important to the world of chemistry for many reasons. The most important reason is probably that it is now used as a unit of measurement. The mole is so important that in 1991 it was first proposed that there be a national celebration of the mole. And a few years later, it became one. Now, each year October 23 world is recognized as mole day. This date was chosen because of the weight of the mole: 6.02 x **10^23** (10/23 = October 23). I too thing think that the mole is very important and understand why it is such a big deal. After learning about the mole, I now think that it is very important and deserves a day to be celebrated.

Kyler, Interesting to think that when I began teaching there was no mole day!!! MW

November 3, 2009 Dust Explosion: This article was about how a sugar factory had an extremely large set of explosions. This incident killed nine people and injured many more. This explosion occurred due to the sugar and dust in the plant. The explosion is a real life example of a chemical reaction. The air, which contained dust, fed the fire and that played a major part in the explosion being so massive. This type of accident could occur at a numerous amount of places and especially factories. It could occur at anywhere that had dust particles in the air. The sugar helped to fuel the explosion too. Making sugar is very dangerous. Chemistry can explain a major part of this incident at a sugar plant in Georgia. The more flammable materials in the air, the bigger the reaction will be.

December 3, 2009 Surfur Hexafluoride: After reading this article, I now know that breathing inn healium or other tone changing gases can be extremly bad for you. I learned that when you hold your breath, in 15 to 20 seconds, your mind knows to gasp for air, but when you inhale a gas your mnd does not recognize what it needs to do nearly as quick. Although it is dangerous, i is still fun and every once in a whlie, I will still probably breath in helium to make my voice funny. I think that iut would be really cool to breath in a gas that makes your voice deep. I realize that too much of it can be very bad for you though.

I suppose too much of anything is bad for you. :) MW

December 15, 2009 Electrons/Wavelenths/Motion Detectors: As of now in Hon. Chemistry, we are learning about wavelenths, electrons, and quantum physics. This is used in the real world in many ways nowadays. One major industry that uses electrons are companies that produce motion detectors. A motion detector works in one of three ways. One is by sending out rays and when an objects position changes the light knows to come on. Another way that motion detectors can work is by receiving a difference in the incoming information. No matter which way they work, the topics that we are learning in chemistry are part of the foundation of how to build products such as those motion detectors.

Good connection to class. MW
