Week 5
This week in science class we have been studying about pH. ph is percent Hydrogyen ions. ph can tell you how much Acid or Base that is in a liqued. An Acid is form 1-6 then a Neutral is exactly 7 and then a Base is from 8-14. On the pH stripes that we were usein were called pH indercater paper. some other papers that there are is Litmus paper. The pink Litmus paper shows a base and th blue Litmus paper show if acid. One thing that we test the pH on was Window cleaner and the Window cleaner was awasa very basic with a pH of 8.0.

Week 4
This week our science class contined to study Ecology. On monday

Week2
1. This week in science class we learnd welll about cell. I relearned that there is a big diffrance between an animal cell and a plante cell. Also this week or whole class leaned more about homeostsais and that homestais is maintaining the internal balence of a cell. Later on in the week I learned more about cell threory and about the people who came you with cell threory. I had a hard time understanding how homeostais work until our teach Mr. Burtis rexplaned it to use.

2. Also this week in science class I also made a comic strip so that for one we could learn more about diffrent cells and for two that other people could learn more about cell. Then wea lso learned about how some of the diffrent organism in the cell do.

Week 1
19 Mar. 2009

1. This week in science class we learnd more about cells.We learn about cells last year but now that we are a grade higher every on thinks that we need to learn more about cells. We learned last year that every thing has to have cell's to live and if you do not have cells then your are nothing. And also we review cell theory and also learned about homeostasis. I don't realy know what homeostasis is. Also we learned more about organization ( cells-tissue-organ-organ syestems) on how they differ and what they are and also what they are made up of.
