Bridge Buliding

We have been learning about forces and how they help shape the sort of bridges that we build.  

We learned that there are three main types of bridge design; beam, truss and suspension.  Using this knowledge we designed and built our own bridges.

Miss Fletcher set the challenge that our bridges had to be 30 cm long and strong enough to hold an object.

In my group there were Sienna M and Nicole.  We used ice block sticks to make the ramp and the triangles and egg cartoons for the base to build our bridge.

Here is a photo of our truss bridge that we named Layenna Foster bridge.  What I like best about our bridge is the triangles on the side.
