From lakes to oceans and even puddles, if water happens to escape into the air, we can call this process evaporation. Let's learn more about evaporation, how it relates to our body, and some really cool facts!

What is Evaporation?

There are so many bodies of water that surround us. Can you name a few? A lake is a body of water. So is the big blue ocean. If we zap them with heat, what do you think will happen? The water will get really warm. If the water gets too hot, it will leave in the form of a vapor or gas. When a liquid turns into a gas or vapor we call this evaporation.

Why is it important? Evaporation is important to our earth's water cycle. Water falls from the sky in the form of rain (or if it's cold, sleet, hail or snow). The water then evaporates back into the air as it warms up. Later, it falls again as rain, sleet, hail or snow. We get lots and lots of water from this cycle, so let's pat evaporation on the back. It is doing its part to move water around and around and around.

How Does Evaporation Work?

From our school window, let's say we see it raining outside. Everything is soaking wet and there are huge puddles everywhere. If we step in the puddle, we will surely get wet!

Later in the day, the rain ends. We look back through the window and see the bright yellow sun. As the sun shines, the heat from the sun warms the puddles. Because of the heat, water molecules begin to dance around. They're so small we can't actually see them with our eyes, but they have a great time bouncing into each other. Boing! Boing!

All of this dancing produces energy. With enough energy, these molecules leave the puddle of water and travel into the air as a vapor or gas. Even though you can't see it happen, it's easy to tell when evaporation has taken place. Before you know it, the water in the puddle has evaporated. There are no more puddles. Time to play!
