This is one of many little "commercials" I do with my Social Science class. I find it easier to have students retain knowledge when they "do" something with it. I typically do them at the end of a chapter to review what they know. This particular one was an advertisement format for a product or innovation in history. This was taped in front of a big piece of green construction paper and then chromo-keyed out in Pinnacle, but could be done in a whole host of programs out there.
