Chemical energy

Okay kiddo, so let's talk about chemical energy. You know how when we eat food, we get energy to run around and play? Chemical energy works the same way but for things like batteries or gasoline in a car.

You see, everything around us is made up of tiny things called atoms. And sometimes, when atoms get together with other atoms, they can make things called molecules. And certain types of molecules can hold energy inside of them, like a little battery.

When we burn things like wood, gasoline, or even candles, we're actually releasing that energy that's stored inside the molecules of those things. That's why we see flames and feel heat coming from them.

But chemical energy isn't just for burning things. It's also used every day in our bodies when we need energy to move and do things. For example, the food we eat is broken down in our bodies into molecules that can be used to give us energy.

So next time you see a fire or a battery-powered toy, remember that there's a little bit of energy stored inside those tiny molecules, just waiting to be used. Pretty cool, huh?
