Balloon Rockets


Super Force from tracey hill on Vimeo.
Can you find my spelling mistake in the movie? Oops!
We carried out an experiment with balloon rockets.

We carefully read the instructions to set up the experiments.
Thread a straw with string.
Attach one end of the string to something.
Blow up a balloon.
Tape the straw onto the balloon.
Count down to blast off.














 We found out what happened when the balloon was filled with different amount of air.
 After we found out that the more air in the balloon the faster it travels because the force is bigger, we got to make up our own experiments.
Some things the children found out: if the force is big enough the balloon will travel upwards, if something gets in the way it will stop the force of the balloon moving, if the string isn't pulled straight there is more friction and it slows the balloon rocket down and if you have 2 balloon rockets on the same string the first one goes faster because some of the air pushes back on the second one and slows it down.
