I'm a middle school science teacher over in Australia and there is a strong push towards using STEM project based learning rather than conventional chalk and talk. I'm all for it, but a little bit stumped for ideas. I want students to be engaged but they need to meet the curriculum standards. I would like to start a project in a few months on Energy - the types of energy, how energy can be transferred or transformed. I have gotten my students to build Rube Goldberg machines before to show their understanding of the types of energy and how it can be changed into other types, but I was hoping if any Science teachers here could give me some ideas?
