Water Erosion: Experiment One

Title

Question: What happens to land when water flows over it?

Hypothesis: I think the land will get soft and flat and wet, also the water will make a canyon.

Materials: 1 ruler, 1 bucket with a hole, one bucket without a hole, measuring cup, rough sand, clay, fine sand wood piece.

Procedure:
1. Set up experiment by: having one side higher than the other, a ruler holding up a cup that the water was falling from, and a hole at the end of the tray where the water came out from.
2. We poured the water into the cup with the hole, so the water would slowly spill onto the sand and erode it.
3. every minute we wrote down what was different than the minute before.
4. When the first 2 cups of water ran out we filled up the cup again.
Observation:

1. The sand slowly curved in to make sand deeper.
2. Water started to flow to the right.
3. Water is making a little a valley in the sand, causing sand to fall down.
4. The valley has turned into a canyon
5. More water is coming down the hill faster.
6. The canyon is getting wider.
7. The canyon is so wide that the water has split into two streams.
8. The canyon is much deeper than before.
9. The two rivers have split into four.
10. the hole where the water drops in is much deeper than the rest of the canyon.
Conclusion: My hypothesis was correct and I learned how water erosion works.
