Question: Is it possible to control the flow of water?
Hypothesis: I think that it is possible to control water by using a damn.
Materials: 1ruler, one bucket with big hole, 5 sticks, 2 wood pieces, 4 cups of water, 1 tray with hole at the end, 1 bucket to collect the water.
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 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. 40 seconds then the water broke through damn
2. The damn slowed the water, but still let it pass
3. hole forming under bucket
4. canyon forming in front of damn
5. Tunnel dug by water under damn.

Conclusion:
The damn slowed the water but was quickly destroyed.
Great work on your blog Nico!! I have a suggestion.. when writing your conclusion, you should then ask yourself, what did I learn from this? What can I now say that is true or that I can test again to see if it is true? For example, you wrote: The damn slowed the water but was quickly destroyed. Then, you could say something like... Therefore, I learned that the dam we created was not able to hold. I think this is because of ________________. I wonder if we changed ______________, could the dam work then? I can say now that water is able to break through dams created by piling up sand and clay. In the real world this would mean that _________________.
