A Bridge for Crossing
Everyday Discoveries
A bridge lets us cross a river or a road. Its deck, the part we travel on, rests on supports that carry the weight down to the ground.
Did you know?
A bridge’s shape and materials affect how strong it is.
Look together
What holds the bridge up above the water?
An idea to try
Compare flat and folded paper spanning two books.
For the adult reading along
A little more to discover
The picture represents a simplified beam bridge with two bank supports and a central pier. Bridges do not all use these supports. The experiment compares paper bridges over two books rather than testing a real structure’s safety.
