Launching rockets

We made air rockets this morning.
We were surprised to see that a rectangular card can turn into a cylinder,
and that a circular piece of card can turn into a cone.
Our rockets are made from a cylinder, a cone on the top and triangles for the fins.
Teacher had a big launcher so we could try launching the rockets.
Our best rocket flew 38 strides (we measured this with our feet).

We discovered that the rockets that started by pointing up, flew quite high but not very far.
The rockets that flew the furthest were the ones that pointed out at an angle.
We also saw a push rocket, a stomp rocket and a water rocket in action.
Pumping enough air into the rockets to make them fly well is hard work!
