- cup for water
- small cup with holes poked into the bottom (can use pushpin for this)
- Place your paper plate on top of your plastic plate.
- Create a hill atop the paper plate using your cornmeal land. Form with your hands.
- Decide what design and materials you will use to prevent your landslide.
- Create your design. Draw what it looks like pre-rainstorm.
- Hold your plastic cup with the holes atop your hill. Slowly fill with water (to create a rainstorm) and observe.
- Draw your hill now. Did it stay in tact during the rainstorm?
- Decide on how you will revise your design and test again!
