This lesson has always worked very well for me. It is a science themed lesson framed around various superheroes and their abilities. There is a segment on physics for Superman and Magneto, genetics for Spiderman, and robotics for Ironman. It works better for upper level classes or kids that are old enough to already have been exposed to these concepts in their normal classes, but it is dumbed down enough so that even the youngsters like it. I have highlighted some potential vocabulary words in red throughout the lesson. If you have small class sizes and can get a hold of some magnets, that is an easy way to make the lesson more hands-on.
