Warm Me Up!

You have been learning about factors that affect climate. You and your family members can observe why a large body of water can affect climate.

Materials

A family walking at the beach.

Procedure

Ask an adult to help you fill one pie pan with water. Fill the other pie pan to the same level with sand. Place the pans on a flat surface and let them stand for about 2 hours to make sure they are both at room temperature. Transfer the pans to a sunny windowsill. In a chart record the temperature of each pan every 5 minutes for 30 minutes.

Results

Which heated up faster—the water or the sand? Suppose the sand-filled pan represented a beach and the water-filled pan represented the ocean. Using what you know about weather, how would this uneven heating affect climate?
