Cloud Viewer

Cloud Viewer

Hurricanes and Climate
Use this cloud viewer to explore the clouds and sky outside. What type of clouds do you see? What color is the sky? Why do the clouds or colors vary?
The Cloud Viewer was the invention of Teri Eastburn, UCAR Center for Science Education.

Grade Level: Elementary, however, the color-of-the-sky discovery activity that complements the Cloud Viewer is especially worthwhile for primary students.



  • Varies. Cloud Viewers are particularly useful on hikes and during extended car or bus rides.


Student Learning Objectives

  • Students learn to classify clouds based on appearance.
  • Students can also match colors found in the sky to those on the opposite side of the Cloud Viewer.  Why do colors vary by height? Where is the sky most white?  Where do you find the bluest color? This activity is especially successful with younger children who are natural explorers and questioners!
