ARE TWO EYES BETTER THAN ONE?
We've been thinking scientifically conducting fair tests and re-checking test. We have used our collected data to make conclusions.
We used paper clips to test which eye could replace the clip in a specific position. We checked which eye or both could thread best/quickest through a hole in paper.
To understand the bones and joints in our hands, we examined an x-ray then built a model of our hand using straws and pipe cleaners.
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.
