Can't wait to see what the children come up with!
It looks like you were all having to work together to build the bridge. Did each group have the same materials to use? I wonder how you defined strong?
Yes we all had the same materials. We determined if our bridges were strong or not by placing a variety of different weights on them. The more weight our bridge could take, the stronger we thought it was.
What did you use to test the strength of your bridges?
We used a variety of weights such as counters and maths material and lead weights.
