Little Scientists: Rain Cloud

June 4, 2020

A classic Museum weather activity that teaches about rain and clouds.

Messy level: 2
(5 = Super messy. 1 = Not messy at all.)

Materials

  • Clear jar
  • Small cup
  • Shaving cream (not the gel or thick versions)
  • Food coloring
  • Water
  • Dropper/pipette

Instructions

1. Mix your food coloring with some water in a small cup. This will be your rain.

2. Fill jar with water until about 1/2 or 3/4 full.

3. Cover the top of water with shaving cream.

4. Using the pipette, gently squirt your colored water on top of our shaving cream cloud.

5. Watch what happens when your “rain cloud” gets heavier and heavier with rain!

But why?

The shaving cream represents the clouds and the water represents the air. The colored water represents rain. As the “rain water” saturates the “cloud”, it gets heavy and eventually is so heavy that it can no longer hold the water. It “rains” down into the jar – through the “air.”
