We've all made hand shadows with flashlights when the power goes out unexpectedly, but have you tried lowering the lights on purpose for playtime? Light experiments are a magical form of sensory exploration with well-documented developmental benefits for kids, while happening to be deceptively simple for even the laziest parent (like me). Setting up a dark environment and incorporating flashlights into your play unlocks a whole new way of looking at the world, mesmerizes tumultuous toddlers, and brings open-ended process play into your home with minimal effort. Light experiments can even work wonders on children who fear the dark.

So cut the lights and grab your flashlights (check for batteries first, because dead flashlights are a bummer) and try out these 10 easy light and shadow experiments for toddlers and preschoolers.
