During science week, the children were challenged to design and test a paddleboat made from an empty carton and powered by an elastic band. We discussed if anyone had ever been rowing or canoeing or been in a peddalo. All these forms of transport have some form of paddle - but how do they work?
Once they had made a successful boat, the children investigated different questions:
How can you make your boat travel faster?
How can you make your boat travel further?
How can you make your boat travel forwards and backwards?
Can you make a boat with two paddles?
For every action, there is an equal and opposite reaction. The paddle pushes the water (action), the water resists (reaction) and the boat moves forward.
