When a flashlight flickers, a ball rolls, and a bell rings, two curious kids trace the energy that made everything happen—discovering how stored energy transforms and moves from one object to another.
When hauling a stuffed backpack up a steep hill feels impossible, two curious kids discover tricks that make the backpack that felt lighter—learning how ramps, wheels, and spreading force over distance can make heavy loads easier to move.
When warmth from a campfire reaches hands, soup, and the air around it, two curious kids follow the heat that traveled three ways—discovering conduction, convection, and radiation in action.
