On Monday this week, we had Gina (Education Officer from Hydro Tas) come to talk to us about water and its importance for all living things. She kindly answered the questions we had written and sent to her before the visit. She explained to us how the turbine and generator worked from the force of the water dropping from the dams and used Lego characters so that we could understand the size of the turbines, generators and pipes at the power stations. She showed us what happens when you rub a very strong magnet along a bar of copper. We all took a turn so we could feel the force and movement of the electrons. The bar of copper that was wrapped in yellow tape was so heavy.

We then went out onto the deck to watch and learn from a series of experiments. We made predictions before each experiment. We did three experiments to see if the amount of water in each bottle, the size of the holes and the height from which the water dropped made a difference to the power behind the water making the turbines spin. Our inquiry on the importance of water continues…
