What You'll Need
Start by filling a vase with water. Then, add shaving cream to create a cloud. At this point, we talked about how the sun heats water found in creeks, ponds, lakes, etc and the water evaporates, rising up into the sky as vapor. Eventually, the water vapor condenses in the cool air to form a cloud. We then talked about why clouds are white (light is reflected from the sun (rainbow of colors from the sun adds up to be white) and sometimes gray (too heavy or too high to allow light to reflect and pass through).
Next, we slowly began adding the color (water). The basis of this was to explain that once a cloud is heavy enough, it begins to rain. Abby decided she couldn't just go a drop at a time...so she decided to squeeze much of the bottle of food coloring into the cloud, resulting in a torrential downpour. :-)
And..why not add a
The next morning she asked to do it again...this time using diluted food coloring. This project was a fun, yet simple way, to visually explain how rain falls from clouds.
Note: A wide rectangular vase/aquarium would have been perfect for this project to visually show a line of precipitation over a greater area, unfortunately we did not have one on hand.
