HEREāS WHAT YOUāLL NEED
What you need for the shaving cream cloud experiment (Copyright KSAT 2023 - All rights reserved)
A large mason jar
Water
Shaving cream
Blue food dye
A pipette (if your food dye doesnāt have a dropper)
DO THE EXPERIMENT
Fill the mason jar about 3/4 full with water
Top the jar with a heap of shaving cream
Using a pipette, drip blue food dye on top of the shaving cream. Watch as the drops go through the cloud and into the water
HOW IT WORKS
This is a simplified version of the water cycle, perfect for younger students
The water represents the atmosphere, the shaving cream represents clouds, and the blue food dye represents rain
Your students should be able to understand that clouds (shaving cream) is lighter than the air (water), and rain (food dye) is denser than the atmosphere, so it falls to the ground.
