Why Do Puddles Dry Up?

Bring evaporation right into the hands of young scientists with an entertaining, hands-on activity. Investigators view videos and images while participating in class dialogue focused on water evaporating from surfaces. A short experiment allows group members to make predictions about water's behavior before the activity concludes with a discussion connecting observations to the water cycle.
