Week 5: On wendsday we did some exparaments with nitorgin. Becaues it expands at 800 times it wil make a tea kettle screech. Then we put it on a some ledace and it breaks like glass if you drop it. Same with a carrot.later he hit a penny with a hammer and it shatterd. And today we talked about aicds and base. On pH paper, red means very strong acid, orange means a storng acid, yellow means a weak acid, green is a weak base, and blue is a storng acid.

Week 4: Just now we learned a liitle bit about the plates and how they move. also were studding ecology now, the differnt types of organsmis interacting together coevlolution symbosiys, compation. And land biomes all over the world. And primary succession and secondery. Secondary is when something growers where it was before. priamry is when something growes that has never grown there.

Week 4 Entry 2: Land biomes costus of: temperate deciduous forest mostly found in europe, coniferous forest what we have in wyoming, tropical like rain forest like in South ameraica. as for grasslands: temperate grassland where bufflo are like paries, savannas afirca. and desert self expalnatory, tundra

Week 2: This week we learned all about cells. like the organelles mitochondria which makes ATP, ribsosomes which make protines, nucleus thah is like the brain of the cell the cell membrane which all cells have but only plants have a cell wall, that stuff.covered all the that chapter in our book. we study this last year and now were doing it again this year.

Week 2 Entry 2: all this week but thursday we made the cartoons on toondoos.com we started this like last thursday where we ha ve to make an account on the site. then we made are frist cartoon about a organal the a 2nd on monday about the beafits of beging multicellular. and 3rd about anotyher organlle on tuesday. then we printed all 3 and turned them in.

Week 2 question: how do the mitochondria and the chloroplast make food and ATP the chloroplaste ueses sunlight to make food but how? it seems like it just does? and the mitochondria makes ATP form protin and the same thing? how it just does or what.mr burtis said well learn about this next year guess i just have to wait.

Week 1: For this week we learned about cells and how they differ. We learned about this in 6th grade but now were going farther in cytlogy the study of cells. We made a four colem pice of paper to write about cell theory, parts of a cell, kinds of a cell, and eukaruyotes. What i kenw in 6th grade i have mostly forggotten like Robert Hooke was the frist to look at cells and not all cells have a cell wall or a nucleas but they all have a cell mebran which protects the cell. Eukaruyotes are the largest cells and humans are made of eukaruyotes they have membrane bound organalls and there usally bigger than singal celled organsmis.

Week 1 Entry 2: Yesterday and the day befor we learned about wikipages. Frist talked about how to get to this page the we had to creat and acoount on this wiki so we could talk on this it's not hard and anybody can do it provied you have a email account then once everyone got on. Mr. brutis told us some things like how to opperat this website and change font/color and the rules like not posting pichers of yourslef then and if you do make sure its of two people and then we wrote a pratice entry.

Week 1 Question: one question i have is that how are cells formed? the can't reproduce like humans do the just appear or do the come from other cells? no doubt we will learn about this later. i would guess that the just brake appart form others but im just not sure. If they break appart form others where did the frist cells come from?

Practice entry 3/17/09 Today in science class we learned about wiwikispaces. I learned how to post on this website, and how to join this site

I dont understand how will all these messages be sperated.
