Rube Goldberg machines in Year 4

Year Four started their 'A bridge too far' topic with a bang. Or to be more specific, rather a lot of bangs and the odd ring of a bell! 
First we learned a little about forces and watched some cool examples  of these 'domino effect' machines on the Internet (this one was our favourite!).

The chldren were set the task of making a bell ring without touching it directly (from a metre away if they could). Their imaginations ran wild and they worked brilliantly in teams to create some fabulous, if rather eccentric designs!

The photos below show how much fun we had and the video link shows our final attempts at ringing the bell. Great work by everyone and lots of fun and laughter. Well done Year 4!
