20.3.23 Building Bridges

Which material makes the best bridge?
 
Today we got the junk modelling out to see what materials were best for making a bridge. 
We tried tissue paper, paper, card, plastic and wood. The tissue and paper were too weak, they couldn't hold the objects. The plastic and wood were really strong and could both hold the objects. The card worked well, especially with extra supports to keep it up. 
We got to practise our cutting and sticking skills as well as having fun building our bridges.
