1. □ Make a hypothesis (guess) – What kind of land shows the most erosion?
2. □ Locate sloped pan with dry sand.
3. □ Fill a graduated cylinder with 100 mL of water.
4. □ Pour water at a medium speed onto top middle.
5. □ Watch the water erode the sand.
6. □ On page 1, describe the erosion using pictures and/or words.
7. □ Locate sloped pan with wet sand. 8. □ Fill a graduated cylinder with 100 mL of water.
9. □ Pour water at a medium speed onto top middle.
10. □ Watch the water erode the sand.
11. □ On page 1, describe the erosion using pictures and/or words.
