Science: Balloon Rocket

Balloon Experiment


In room 15, we have done a balloon experiment for our science rotation. We visit every class for a different experiment.


Equipment:
  • 3 balloons
  • String
  • Straw
  • 2 chairs
  • Tape


Prediction:
I think when I blow the balloon and let go of it, it’s going to fly down the other end of the string hitting the chair.


Observe:
When I blew the balloon. Marcus taped it to the straw and I let go of the balloon and the balloon went flying down the string and hit the chair.


Explanation:  
When you blow the balloon up, all the air inside the balloon wants to go out. So when I let it go, all the air bursts out of the balloon causing it to move along the string to the other end.
(Balloon) I believe I can fly!
