Overview: In today's episode, Maddie is having fun outdoors. First, she's in a playground learning how we keep swinging on a swing and how gravity helps us slide down a slide. She uses a special camera to show us how friction stops us from going too fast. Next, Maddie goes to a factory where plant pots are made. She finds out how clay and shale from a quarry are mixed, shaped and baked into plant pots, then uses a special thermal camera to show us how hot the plant pots get when they travel through a kiln!
