Hypothesis: Yes it is possible by using a damn.
Materials: 1ruler, one bucket with small hole, 5 sticks, 2 wood pieces, 4 cups of water, 1 tray with hole at the end, 1 bucket to collect the water, 6 small plastic glasses, 5 paint brushes
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 reinforced the built damn to stop water from coming down.
3. We poured the water into the cup with the hole, so the water would slowly spill onto the sand and erode it.
Observation:
1. 20 seconds and water has not passed
2. 40 seconds and water has not passed
3. 60 seconds and small hole has formed under bucket
4. 2 minutes past and there's big hole under bucket, no water passing
5. 2:20 the damn is still holding
6. 2: 30 the water is stuck in the ditch
7. 3:20 and the pool of water is spreading
8. 4:20 water is starting to cover more sand
9. 4:40 more water poured in and nothing changing
10. the water is getting really high, covering more sand
11. 5:50 water barley coming out of ditch
12. 7:00 more water coming down

Conclusion: the damn held for 7 minutes, but then the water slowly came down.
