Print Prep

In this lesson, students develop a model to explain how water cycles from the Earth’s surface to the atmosphere and back again. In the activity, Make It Rain, students create simple models of the ocean and sky to see how these two systems interact. Students compare how the temperature of the ocean and the temperature of the sky affect evaporation and condensation.
