Rubber band cannons - Science with children - ExpeRimental #1
Build a rubber band powered cannon from a crisp tin and a drinks bottle and use it to explore projectile motion and conservation of energy...or just knock down ...
==========
Dead on target. Yes! This is a simple toy cannon that's easy to make. My boys have had loads of fun playing with it. I'll explain how to make it in a moment, but the thing I love about it is the fact that it allows children to explore energy, forces, and motion all while making something. You can fire different things out of it. You can control how much you pull the rubber bands back. You can change the angle. In other words you can explore projectile motion, the way in which things fly through the air. To make one of these cannons, you need to start by cutting off the bottom of one of these crisp tins. So we'll take the scissors and push them through. You'll probably want to do this yourself because it's a little tricky We cut it right the way around. Next yo...
