Thread:Question about the Lesson Plan (1)

I set up the lesson plan so there was a "teacher set up" and then the students doing the rest of the experiment. The teacher set up was cutting the soda bottles. I didn't know if I should just put that in the part that the students do or not. Do you think it would take up a lot of time to have the students cut the bottles during the class time? Just wondering what you guys think. -Beth
