Revised Laws

Station One:
I think that this station would be Boyles Law because the only thing constant was the temperature because it didnt change when the syringe was being pulled out & pushed in. When the syringe was being pulled out the molecules had more room which caused less collision. which caused less pressure. The volume in the syringe changed everything it was released & pushed in. When the pressure of the air was increased because of the syringe being pulled back out, the marshmallow expanded because the molecules had more room to move instead of collliding. So thats why the marshmallow shrunk when the syringe was being pushed in.

Balloon Station:
I think this station would be Gay-Lusacas Law because the temperature clearly was hot which formed fast moving hot molecules & that effected the pressure of the balloon forming to the flask. because the heat made it vacuum into the flask as far as it would go & the pressure pushing the ballooon into the flask was caused by the heat. So the temperature & pressure are directly related. The volume was constant because when the balloon was formed over the top of the flask the molecules were causing collisions.

Pippett Station:

I think this station is Boyle's Law because the pressure was all of the books on top of the pitppett to show how far it would push the liquid through the tube. The volume is how much liquid was being moved by the pressure of the # of books. so the pressure & volume are inversely related. The pressure was the books on top of the pipette. The liquid inside was tightly compressed and couldnt move when the pressure was on top of it.

  1. You quickly presented your points and then proceeded to back them up. Some spelling mistakes :( but all around good job!

  2. I liked how you got to the point on what you were trying to say, then went on and explained. On station one you did a good job on asking yourself 'why?'. You had a couple spelling errors, and punctuation errors as well. But overall very good!
