Nitrogen Cycle 

In class today, we were doing this activity, where Mrs. Smith made us to be cute tiny little nitrogen atoms. We were to travel from stations to stations that were labelled different each. 
Why didn't everybody go to the same station in the same order?
In the real nitrogen cycle, not all of the nitrogen atoms clump up together in a group and travel together. Some of the nitrogen atoms are on one "stations" and some on other "stations".
Did you go to the same  station twice? If so, what does this tell us about cycles?
It tells us that in a cycle, you can go back repeat part of a cycle. 
Was there one station that seemed to have a lot of people at it? Why or Why not?
Yes, sometimes, people roll the dice and have the same number as some other people. Then, people crowd around that area. 
What do you think that the point of this activity was?
I thought that the point of this activity was to let us see how it is in a cycle. And to teach us about cycles, that cycles doesn't have a specific chronological order. You can repeat some of the stations. And, maybe, Mrs. Smith wanted to see Juegan be the poop and see his reaction. :P
