If you are interested in the water cycle, you could study the evaporation rate when water is moving and still, investigate the evaporation differences between saltwater and fresh water, or compare how concrete and soil affect the rate of evaporation.

Troubleshooter's Guide

Here are some problems that may arise during this experiment, some possible causes, and ways to remedy the problems.

Problem: No evaporation occurred.

Possible cause: Your containers did not receive enough light or heat for measurable water to evaporate. Try putting all of them in direct sunlight.

Problem: Evaporation seemed the same in all the containers.

Possible cause: There is not enough difference in the surface areas of your containers. Try using larger trays and smaller trays.
