Demonstrating Water Erosion Of Land Masses


  • Dirt
  • Small gravel
  • Sand
  • Deep baking dish or pan
  • Book
  • Pencil
  • Paper cups


  1. Start by pouring sand, dirt, and gravel in layers at one end of the dish. This is your “landform.” Use your hand to smooth the land. Leave the other end of the dish empty.
  2. Dip your fingers into the water and slowly drip water over the land. Repeat this until the land is wet. What do you observe about the water that falls on the dry land? Record your observation
  3. Slightly pick up on the end of the dish with the land in it. Place a book under that end.
  4. Use a pencil tip to poke a tiny hole in the bottom of a paper cup. Hold the cup above the land. Slowly pour water into the cup and watch what happens to the land while the water drains onto it. Observe what is happening to both the land and the water.
  5. Once the water has stopped draining, record your observations and include a drawing of your land’s new form.
  6. Add another book under the land end of the dish. Repeat the water draining activity. Observe what occurred with the land and water this time. Record your observations including a drawing.
