Science fair projects are fun for middle and high school students. Weather is a great topic for science fairs and clouds are fun to study.

Fun experiments, real life observations, thunder, ​and lightning... clouds are very cool!

Interesting Facts About Clouds

We see clouds every day in the sky and they change rapidly. Some bring bad weather and others are simply beautiful to look at. Clouds are the foundation of Earth's weather and that is what makes them so interesting.

  • Clouds are a visible body, usually white or gray, of fine water droplets high in the earth's atmosphere.
  • They form through a process of evaporation of the earth's water that then condenses in the atmosphere.
  • There are 10 main types of clouds, but there are actually more than that!
  • Clouds form on three levels: low, medium and high. A cloud's height is measured by where its top is in the atmosphere.
  • Clouds that are higher in the air move faster because they are pushed by the jet stream.
  • Fog is a cloud that is close to the ground.

Cloud Science Fair Project Ideas

  1. Make your own cloud. It is easy to make a cloud in a bottle and use it to demonstrate how clouds form. This project involves matches, so get permission from your teacher first.
  2. Study your local clouds. Take pictures of different clouds in your area for a month. Note the temperature and other weather conditions for each picture. Then describe the type of cloud and give the reasons it formed at that time.
  1. What does a thunderstorm cloud look like? Explain the difference between rain clouds and thunderstorm clouds.
  2. Explain the different cloud shapes. Use diagrams or pictures to explain the difference between clouds and their height. Cotton balls can be used to make life-like clouds pop out of a board.
  1. How do clouds form? Draw diagrams to show how a cloud forms.
  2. How fast do clouds move? Take a video of clouds floating across the sky and explain why some clouds move faster than others.
  3. How does fog form? Take pictures in the fog and explain why it often occurs early or late in the day.
  4. Can clouds predict the weather? Explore this question through photographs and your own observations from watching clouds and noting the weather that followed each.
