Description:

This three-part activity consists of an activity that student groups develop themselves, a given procedure, and an optional demonstration. First, students discuss examples of evaporation and then design and conduct their own test to find out whether heating water has an effect on the rate of evaporation. While waiting for their results, students conduct another evaporation activity using single drops of water on 2 paper towels, one of which is heated. The optional demonstration compares the rate of evaporation of hot and cold water using a sensitive scale or balance. In each of these experiences with evaporation, students will identify variables, consider how to best control them, and use their observations to conclude that heating water increases the rate of evaporation.
