How does a microwave oven heat food without burning it?

A microwave oven uses waves to make food hot, just like how a radio makes music come out of your speaker.

Imagine you're playing with a jump rope. You shake it up and down really fast, that's like the microwave waves inside the oven. These waves go through the food and make the tiny particles in it move faster, which means they get hotter. It’s like when you run around a lot and feel warm.

Microwaves have special waves that can pass right through most foods, even plastic or paper plates. This means your food gets hot from the inside out, not just on the outside. So it doesn’t burn like when you use a regular stove.

The waves don't stop moving until they hit something that can hold heat, like the sides of the oven or the food itself. That’s why your soup gets warm all over, but your plate might just get a little toasty. It's like when you sit near a fire, you feel the warmth, but it doesn’t burn you unless you’re too close.

And that’s how microwaves make food hot without burning it!
