I use this as a choice for my energy task. It is also sold on TpT, but you can use this as a separate activity. In middle school, students get stuck on learning the forms of energy, but for High School and to really be distinguished at a middle school level, student must be able to understanding the transformations of energy. This graphic organizer allows them 6 boxes to illustrate and provide dialog about how energy is transformed. I make them label PE and KE too. The first box is always a power plant (hydroelectric or nuclear) or solar panels or wind farm. I model a cell phone or kitchen appliance and they have to come up with their own example.
