After learning about the different states and properties of water and the water cycle, P2/3 are now busy looking at how water can be used as a renewable source of energy. On Monday we made mini water turbines using bottles, canes and a lot of water. Back in class we then looked at pictures and video clips of hydro-electric dams. We discovered that the higher the water falls the faster the bottle spins around and in a hydro-electric dam the spinning would create the energy.
