Bridge

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 Andrew and Shiah.
We used cardboard and egg cartons  to build our bridge.

Here is a photo of our bridge. 
What I like best about our bridge is that it worked and it could hold a weight.
