Tuesday October 18
Today we did an assignment out of our books about the three main cycles, they were the water cycle, the carbon cycle, and the nitrogen cycle. Some people were allowed to check out books over night if they didn't get finished during class. This is due the beginning of class Wednesday.
Some things that I think are good to know are:
-how waste water is filtered and the separate steps taken to purify it
-how plants and animals get nitrogen
-what the difference between free nitrogen and nitrogen already processed by bacteria is
what I wondered was what happens if there is too much or too little free nitrogen in the air.
