5-21-09 During this week our science class learned about Dry ice Liquid Nitrogen and also pH predictions. First off we watched Mr. Burtis use dry ice ibn other chemical based water. We also watched Mr. Burtis freeze different things such as a carrot, pennies, and lettuce. The carrots and the lettuce broke as well as the penny. Finally today we We did exeriments with pH based chemical change and are doing this stuff as homework.

4-30-09 This week in science class I learned about Interactions about living things. One was competition, which is when 2 or more individuals or populations that try to use the same resource or that happens in the same population or happens between two populations. A second one that I learned about is symbiosis. Symbiosis means a close long-term association between two or more species. The three types of symbiosis are mutualism, commensalism, and parasitism. In conclusion these are just a few things I learned this week in science class.

4-9-09 In week 2 we have been talking about cells. I learned that Shwan was one of the founders of the cell theory. I also learned about Homestasis which means maintaining body temperature. During this week we also learned about how to make my own toondoo. My toon was about the nucleus. I used a football player to express the nuleus.
