SPI 0507.9.3 Describe factors that influence the rate at which different types of material freeze, melt, or evaporate.

Activity 1 - Evaporation PowerPoint Part 2

• Temperature

• Wind - Air Circulation

• Exposed Surface Area

• Humidity

Activity 2 - Create a chart for Science Notebook on Evaporation.

Activity 3 - Experiment for Evaporation

Put 2 teaspoons of water into several pie pans.

1. The control should be placed in the room under normal conditions.

2. Try these variables:

   • Place one in a sunny window.

   • Place one by a fan.

   • Place one by a heater.

 Which pan of water evaporated faster?
