Breaking Strain - Room on the Broom

Today we read Room on the Broom and talked about breaking strain. 
We learnt about the Space Elevator. 

This is an elevator that goes all the way into space. It can't be built because of the breaking strain of the metal.

We worked out the breaking strain of the broomstick by estimating the weights of the animals and adding them up
