Teaching Science When You Don’t Know Diddley-Squat is a series of science lessons that can be taught with no science background and materials you probably already have at home, or with a quick shopping trip. If you have a club meeting coming up tonight, and don’t have much time to prepare – these lessons are for you. They are designed to get young people thinking using their natural curiosity. Science isn’t about memorization; an internet search can give you facts. It is about using critical thinking to ask questions and discovering answers on your own. (and determining whether those internet answers are correct)
