Bridges: A S.T.E.M Project Activity and Exploration

Bridges made from straws and tape.

                                  Engineering a Bridge: 

1. Beam bridges are made of horizontal beams supported by piers at each end.

2. Truss Bridges are a combination of triangles made of steel.
3. Arch bridges are made up of arches supporting the bridge and are naturally strong.
4. Suspension bridges are long bridges, such as the Golden Gate Bridge.

Straws taped together to make triangles.

Close to completion of a Truss and Suspension Bridge.

Blocks used to explore Suspension Bridges.

Bridges connect two bodies of land.

Discussion on making the bridge level.
