Experiment 4: Dam

Question: Will a dam we create stop the water flow



Hypothesis: I think that the dam will work and hold of the water.




Materials:4 cups of water, Bucket with big hole, Ruler, sand, hard sand, clay, Bucket with 3 pipes and small hole at end, wooden wedge, Cubes, Leaves.






Procedure:Put sand and hard sand and clay in the bucket with pipes. Mix the sand and clay.
make sand 20 cm in the length is the side without the hole. Take the wooden wedge and put it under the sand side. Put the ruler under the bucket in the sand side. Make the dam, Pour water








Observation: The dam easily held of the water for 2-3 minutes. The water tried 2 different ways until it finally went under the dam. It shocked me because I never thought of that. Near the end of the experiment the water also went from the sides.





Conclusion: I think the water outsmarted us because we thought that the dam will hold off the water. But instead the water went under the dam and went normal. This was not easy for the water because for 2 -3 minutes the water was blocked off.
