Investigating Condensation and the Water Cycle

Step-by-step Lesson and Free Printables 

Most kids are familiar with the terms precipitation, condensation, and evaporation, but very few of them really understand what those words mean. Just ask your students to name three examples of condensation in everyday life and watch their eyes glaze over. Huh??

Most kids understand that precipitation is a fancy word for different forms of water falling from the sky, like rain, snow, and sleet. Most kids also understand that evaporation is what happens when water “disappears” on a warm day, such as a puddle drying up. They know that evaporation means liquid water has become water vapor.

Condensation is a little harder to grasp. If you’ve taught your students that clouds form as a result of condensation, they may think that condensation only happens in the sky. Do they know that condensation happens all around us, every day? If they understand that water droplets on a cold glass are the result of condensation, where do they think the water comes from? Inside the glass?
