Frank Gregorio has put together some amazing video trailers that are fantastic and inspiring and, I think, are a great way to introduce science topics. Between the stunning video and moving music, they really grab your attention and give enough information that they "hook" you on the subject.
Introduction to Life
Introduction to Biology
Introduction to Biochemistry
Introduction to Cells
Some people have complained about the "bad science" in the Intro to Life video. I saw it as a springboard for discussion. The questions are posed about what makes something alive--movement, reproduction, etc., and then it says, "but water moves," "fire reproduces..." Well, water flows, fire spreads, but this is a great introduction to scientific thinking. What is the difference? Does water act for itself, like something that is alive, or is it acted upon, because it is not alive?
Anyway, I really like these videos for kicking off topics.
