windmill

This week’s class, we introduce the conservation of energy.  We build a windmill which will transfer wind energy to rotational energy and use rotational energy to lift heavy blocks.  It just gives them an idea of use renewable energy to save slow down climate changes.  It was not super challenging to build the windmill but to line up the fans properly and have the block system on the right side caught them off guard.  Once they realized it, the experiment went smoothly, and big thank shut out to Daniel who was a fantastic helper that day.
