What Is Conduction? — Reading Comprehension

Have you ever touched a metal doorknob on a cold day and felt the chill? Or grabbed a metal spoon from a hot pot and uickly pulled your hand away? That feeling comes from conduction—the way heat moves through solids.

Conduction happens when heat passes from one particle to another. In solids, the particles are packed very close together. When one particle gets warmer, it starts to move faster. It bumps into the particles next to it, passing the heat along. This is how the heat moves through the material.

Metals are some of the best conductors of heat. That’s why pots and pans are made of metal—they heat up uickly and cook food evenly. Other materials, like wood or plastic, are poor conductors. They do not let heat move through them easily. These materials are called insulators.

Think about cooking. If you stir soup with a metal spoon, the spoon gets hot because heat from the soup travels through the spoon to your hand. But if you use a wooden spoon, it stays cool because wood doesn’t conduct heat well.

Conduction is important in many parts of our lives. Engineers think about conduction when they design buildings, cars, and even space rockets! They choose the right materials to either move heat around or stop it from moving.

Fun Fact: Some animals, like polar bears, have thick fur that acts like an insulator. This helps them keep their body heat from escaping into the cold air!
