You will need the following materials:

2 cake pans
10 cups of sand
a spray bottle with water
4-6 ice cubes
a straw
a pair of goggles
a blow dryer
newspaper or other table covering
four pans partially filled with sand, one with a spray bottle, one with ice cubes, one with a straw, and one with a blow dryer

Hypothesis and Data Collection: Water (Pans 1 and 2)
Divide the sand into two equal parts. Put one part of the sand in pan 1 and another part in pan 2. In each pan, push all the sand to one end, as shown in the image.

Part A
In pan 1, you’ll spray the sand with water. In pan 2, you’ll set ice cubes on the sand to melt. Predict what will happen in each pan.
Part B
Now, spray the water on top of the sand in pan 1. Then set the ice cubes on the top of the sand in pan 2. Wait for the ice cubes to start melting. Then write down your observations about the sand in each pan.
