What do you think will happen in a model built using these steps? Predict how erosion and weathering will occur in each container and whether the rate of erosion will be different.
How could she build a model to compare how different forms of water cause erosion on a hill?

Obtain two identical containers and dry sand.
Shape equal amounts of sand into a
slope on the side of
each container.
Spray water on the sand in one container. The sprayed water represents
rainfall
.
In the other container,
place ice cubes to melt on the sand. This represents snow or glaciers.
.

Observe and record the changes in the sand.

Analyze differences between the two containers.
