Challenge Question:
As a group, can you make a Lego bridge to cross a river as wide as your hand?
Your bridge must stand ONLY on dry land, without any part sitting in the river.
We will test our bridges for strength. If you press on your bridge with your hand, does it break? If so, how can you make it stronger?
Brainstorming
-
What is a bridge?
-
What shape do we usually see for a river?
-
Can we add other plants or designs to our drawing?
