Last Wednesday, our class took a trip to Raheny Library to attend a LEGO workshop as part of Science Week. The workshop was all about renewable energy. We learned about the three types of renewable energy- wind energy , water/ hydroelectric energy and solar energy. We then made our own windmills using LEGO. We attached a battery to our windmills to make them rotate like real windmills. We had so much fun and learned so much about renewable energy.
