Class 4 Bridges

For our D&T project this term, Class 4 are building bridges. We’ve been exploring different ways to stiffen and reinforce cardboard. A simple flat “beam” of paper can’t support much weight on its own, but add a curved “arch” underneath and suddenly things are much stronger! We’ve also been exploring corrugation and lamination techniques to further reinforce the structures we have been building. Check out some of our prototypes below!
