A class from the Secondary Program at Perkins School for the Blind wanted to know what materials would stop water from flowing. Each student helped pick the nine materials that they would test. This what they found…

- gutter
- styrofoam
- rocks
- dirt
- noodles
- grass
- rice
- magazines
- oatmeal
- block styrofoam –oasis block, as used in greenhouse
Procedure
1. Set up the gutter for experiment.
2. Fill the bags with each material.
3. Examine all materials.
4. Student chooses which material to trial next.
5. Student sets up the trial by placing a cloth bag into the gutter.
6. Pour water into the gutter.
