We measured how far the balloon rockets would run vs. how much thrust they produced (i.e. how much air was in the balloon). We are learning how to be good scientists by making sure we are testing using 'fair test' principles.

The power of 'Thrust'
We have been investigating the power of thrust. We made balloon rockets that run on a string cable.
We measured how far the balloon rockets would run vs. how much thrust they produced (i.e. how much air was in the balloon). We are learning how to be good scientists by making sure we are testing using 'fair test' principles.
