This week we did labs (or Mr. Burtis did most of them). We learned the density of water which is 1g per centimeter cubed. Also we learned that dry ice will freeze at -109f or -78c.Dry ice is not oxygen it is made with carbon dioxide that is compressed until it freezes. Then the best of all was the liquid nitrogen. That he froze the carrot and it boils at -320f.

Week 4

This week I learned about the interactions of the animals with thier enviornment. Such as predator & prey, competition, and symbiosis. Also the limiting factors like food, water, shelter, and the population of a species. We also when over the water cycle again, then we went over the carbon cycle.And how the carbon goes through the animals and machines. Close to the end of the week we learned how plant grows from the pioneer plant to the climax plant that appears. That is what we learned about in this week

Week 3

This week we learned about animals and what category they go into. The categories are primary, 1st consumer, 2nd consumer. The primary category uses the sun to produce energy. The 1st consumer eats the primary and the 2nd consumer eats the 1st consumer. Then there are other groups. One is called a scavenger and they eat dead animals. Another one is an omnivore and they eat plants and animal. The other two eat only meat and only plants.
