Year 4's Science Fun

Today in Year 4 we investigated Hydroelectric power and found out how this energy is transformed into electricity. Hydroelectric power is a renewable energy source which harnesses the power of moving water to produce electricity. As the water flows down through a dam of water, its movement energy is used to turn a turbine. The generator converts the turbine's mechanical energy into electricity.

We investigated this outside and made our own hydro water wheels (turbines). We investigated if the number of paddles (spoons) on the wheel made a difference to the speed of the wheel. We found out that the more paddles there were, the faster the wheel would spin, which means more electricity would have been produced if it were a real turbine.
