Potions and going back in time to see how science started!!

This is a video put together in response to some questions from Gus at St. Michael's! It shows a bit about potions, and a little on two early scientists, Aristotle and Galileo. Galileo especially helped start modern science because of his use of observations and experiments. Prior to Galileo, Aristotle (from ancient Greece) had made use of philosophy to think about how the world works...this is not entirely how modern science works, but it began a way of thinking about Nature and how it works!
