Materials
- 3 2-Liter Plastic Bottles
- Soil/mulch/soil with dead leaf cover (enough to fill one of the 3 bottles)
- 3 plastic cups
- 2 wire hangers
- Blocks (to support bottles)
- Watering can
- Tape
- Scissors or utility knife
Students build a variety of different soil models inside 2-liter bottles that have been cut in half. They then sprinkle water on top of the soil until it runs of into the plastic cup. They then examine the contents of the plastic cup to find what type of soil resists erosion the best.
