Experiment 4: Aquatic Engineer

Question: Is it possible to control the flow of water?

Hypothesis: I think it is possible to control the flow of water because if you use good materials it probably stop it.

Materials:

• Fine sand 
• Ruffle sand
• Clay
• 2 wood pieces
• Sticks
•  5 Paint brushes
• Cup with small hole 
• Ruler
• Sponges
• 7 Small buckets
• Big bucket
• Water
• Stream table
• 2 Popsicle sticks
• Colorful blocks

Procedure:

First we mixed the 3 types of soils and then putted at the bottom of the stream table 1 of the wood piece and then we added all the paint brushes, sticks, the 7 buckets, the Popsicles sticks, the colorful blocks and the sponges to prevent the water from going outside the stream table. After that we added the ruler on top of the stream table and on top of that we putted the bucket with the small hole on the bottom. With the megearing cup we poured in 4 cups of water and putted in the cup. We putted the big cup to hold the water under the stream table. Then we started the experiment.

Observation: 

I saw a big hole creating right under the bucket with the hole. 

The water was staying all in the same place where the Dun was, but then the water started going trough the materials that got put there but just a bit got out.

Conclusion:

My Hypothesis was partly right because at first me and my group members thought that the water would have not made it through but then at the really end some of the water started getting through. I still think that we can control the water from flowing.
