Today we looked at different kinds of bridges, some have wires, some have arches and some have towers. We tried to make a bridge using a sheet of paper between towers of blocks. We discovered that the bridge was too weak with just paper so somebody decided that we needed to use something stronger as the road over the bridge. Here are the things we tried and the results we got:
The lid of the block container............................ very strong
Paper by itself....................................................very weak
Paper with the sides turned up........................... very strong
Paper with an arch under it.................................very strong
Card .................................................................weak
Move the tower blocks a little closer and use the card................................strong
Have a look at the photos to see our results
