We brainstormed a list of everything in our classroom that required energy to operate. We sorted items by which type of energy they used, then we used a Venn diagram to further sort items as "wants" or "needs". We decided that we would like to give up something that would really make a difference, so we turned off all the overhead lights for the day. We realized that there was enough light from the sun to do our schoolwork. We enjoyed this challenge so much that we have decided to continue for the rest of the week and hopefully even longer!
