Clouds in a Jar!

Last week we explored water through experiments of sink or float. This week we created clouds in a jar~this is one of the most exciting things we've done all year! This activity teaches the concept that clouds get so full of moisture, it eventually has to rain. Items needed for this project are: a jar or vase filled halfway with water, a cloud of shaving cream poured on top, a cup with liquid watercolor/water mixture, and a medicine dropper to dispense the liquid color. As the students dropped more and more watercolor into the clouds they saw the trickle through effect, much like how a cloud would rain down on us.

 Our experiment also reminded us about color mixing concepts as each student had two primary colors in their cups. The more that everyone mixed and filled their clouds, the more exciting it was to see secondary colors appear.

 Amazing creations!
