Intro
Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do scientists call heat energy on the move?
The Big Idea
Heat is energy that moves from a warmer thing to a cooler thing. That is why scientists call it energy on the move. Let's watch it travel!
Jiggling Particles
Step one: jiggling particles. All stuff is made of tiny particles that jiggle. The more they jiggle, the more thermal energy the thing has.
Energy Flows
Step two: energy flows. When you touch something hot, its jiggling particles pass some energy to your skin. Heat always flows from the warmer thing to the cooler thing.
Same Temperature
Step three: the same temperature. Energy keeps flowing until both things are at the same temperature. Then the flow slows down and stops.
A Closer Look
Let's take a closer look! The hot thing has fast jiggling particles. The cool thing has slower ones. Energy flows from hot to cool. Soon both feel the same.
Quick Facts
Quick facts! Heat is energy on the move, while temperature tells how hot something is. Hotter things have faster jiggling particles. Heat always flows from warmer things to cooler things. It stops when both things are the same temperature.
Think Like a Scientist
Now, think like a scientist! Hold an ice cube in your hand for ten seconds. Notice how your hand feels. Which way does the energy move? From your hand to the ice, or from the ice to your hand? Then tell a friend what you found out.
Outro
Heat is energy moving from warmer things to cooler things until they match. Science is amazing! Stay curious! The more you look around, the more wonders you will find, so keep your eyes open!
