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 hot cocoa steams and cold metal stings a finger, two curious kids dive into the mystery of heat and temperature—learning that heat is moving energy and temperature tells how fast particles are vibrating.
Heat moves in three main ways. Conduction transfers heat through direct contact, like a metal spoon warming in hot soup. Convection moves heat through fluids as warm air or water rises and cool air or water sinks. Radiation sends heat through empty space as invisible waves, like warmth felt from the Sun or a fire.
