We have been learning about energy efficient houses, how to save energy and how to generate clean energy without using fossil fuels such as oil, gas or coal. We made circuits using the energy from solar panels and tested out buzzers, lights and fans and recorded our results. We also left a tap on for two minutes whilst we brushed our teeth and discovered when we measured it that we had wasted a shocking 6.7 litres of clean water. Remember to turn off the tap!
