Materials, and how they are put together, are very important when making a bridge.
Investigate the best way to build a bridge between two supports by making a bridge out of your chosen materials and then put enough weight on it to break it. Then try to make another bridge by either using a different materials or by using the same material and making it differently.
A worksheet for this activity can be downloaded here and there is also an accompanying video.
