My students really enjoy this activity! I use it as a summative assessment at the end of this portion of the unit but it could definitely be used in many other ways as well. Students will choose a favorite cartoon clip or episode (though I allow them to choose clips from multiple cartoons as well if they find that easier). Then, they will find ten examples of energy transformations that take place in the cartoon. Next they will defend their examples explaining how the law of conservation of energy is actually followed in that particular scene. I have students record the time stamp of the scene they are referring to, a snapshot of the scene, and a link to the video - so I can more easily assess their work. Feel free to manipulate your requirements in any way. I often tell my classes that if they pause the cartoon at just about any point you will see an energy transformation happening. Examples include: thermal energy, radiant energy, sound energy, electrical energy, chemical energy, mechanical energy, etc. A rubric is included. I teach in a 1:1 laptop environment but this could be done in a computer lab or adapted as a printed worksheet (likely without the screenshot column).
