Bridge Building

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 a track

In my group there were (name who was in your  Mikayla, Ella and Olivia .  We used egg cartons, ice block sticks, a box and hot glue  to build our bridge.

Here is a photo of our truss bridge.  What I like best about our bridge is the triangles.
