Mrs. Meyer’s 4th grade science class has been studying a unit on weather. In order to better understand how rain occurs, the students performed an experiment using 3 simple items: water, shaving cream, and food coloring.
The shaving cream represented clouds, the water represented air, and the food coloring represented the rain. As the food coloring saturated the cloud, it got heavy and could no longer hold the water, so it rained down into the cup. This experiment showed the students how rain actually develops in the clouds and then falls down to the ground.
