What is convection?

Hot air rises, and cold air sinks, that’s convection! It’s like when you blow on a hot soup to cool it down, but instead of your breath doing the work, the air itself moves around.

Imagine you’re sitting by a fire. The air next to the flames gets warm. As it warms up, it becomes lighter and starts to rise, like a balloon letting go of its string. Meanwhile, cooler air from nearby comes in to take its place. This moving air is called a current, and it keeps going until everything around the fire feels warm.

Think about when you’re baking cookies. The hot air inside the oven rises, and the cooler air from the bottom moves up to replace it. That’s convection working hard to make your cookies golden and delicious!

So next time you feel a breeze near a heater or notice smoke rising from a candle, remember, that’s convection doing its job! Hot air rises, and cold air sinks, that’s convection!
