To start our science topic on the skeleton and movement, we used dog biscuits to demonstrate our understanding of the human skeleton.
Roald Dahl Science – Rocket Balloons
We worked in teams.
We observed what made our balloons move – the power of air pushing the balloon as the air rushed out.
We learnt how hairy string slowed down the balloon. “This is friction,” said Alfie.
“By blowing more air in, the balloon will travel faster and further,” explained Peter.
Peter also observed that the sellotape and the more air could weigh the balloon down and also slow down the balloon.
We put what we had learnt about the power of air into action.
We built a vehicle and tried to use trapped air in the balloon to power it.
