River Formation

In my 9th grade science class, we are working on the formation of rivers. Are teacher asked us to perform two experiments on river formation. My group chose to experiment underground springs and lake overflow these were the results

Experiment 1-Underground Springs

How to Test It-Using plastic pipping and the soil provided to us we elevated the container because rivers go down hill and, put the pipping under the soil, and connected the pipping to the faucet to create the illusion of an underground spring.

Hypotheseis-I think the water will pass through the pebbles and just become a lake at the bottom because the pebbles have enough space for water to pass through, and i think the sand and diatomaceous earth would form rivers and a lake at the bottom.

Diatomaceuos Earth- The earth made two rivers then at the bottom of the container since its elevated it made a "lake" at the bottom of the container.

Pebbles- The water didnt form any stream, instead it went under the rocks because there is enough space for water to pass through. It created a "lake" at the bottom of the container.

Sand- The water created two streams and created a "lake" at the bottom of the container.

Conclusion-I can conclude that our experiment was successful. We repeated the process of digging a hole for the tubing, packing the soil over the tubing and turn on the water and seeing what happens. From our results we can conclude that the earth and the sand make rivers and the pebbles only make a lake at the bottom.

Experiment 2- Lake Overflow

How To Test It- To create a "lake" we made a pile of the soil and made a hole in that pile to create the illusion of a lake. Then we poured water into the "lake" seeing if the water would force a opening in the "lake" making a "river"

Hypothesis- I think that the pebbles will not create a opening for water to pass through and make a river. I think the sand and the earth will make openings for water to pass through and make a river.

Diatomaceous Earth-when pouring the water into the "lake" the earth made a opening in the "lake" making a "river" going down hill.

Pebbles- In didnt even make a lake the water just passes through the pebbles.

Sand-The "lake" made a opening allowing it to make a river.

Conclusion- In my opinion i dont think this was a good experiment. We didnt elevate the container and rivers flow down hill so it was not accurate on what would actually happen. The experiment was a fail. In conclusion of our results to this experiment, the pebbles didnt even make a river when you pour the water in the "lake". The sand and earth made a opening for a river though.
