Experiment: Runoff

Hypothesis: I believe that when the lake overflows that it will runoff and form into little rivers and then runoff and make another lake.

Set up: First we put diatomaceous earth in a tub, then added water and mixed. Then we scooped out a little hole in the middle of the diatomaceous earth then put a cup in the middle of the scooped out hole then build around it and then pulled the cup out. Then we poured water to hole even with the rim.

Experiment: We poured water in slowly and it didnt do anything. Then we filled the graduated cylinder with more water and poured it at a faster pace. Then it started to see that it was overflowing and it branched off and then ran off to the outside of the of the tub.

Conclusion: Are concluuton was that if it rains a ton it will overflow and runoff into a lake, but if it doesnt rain a ton it wont overflow and make river.

science 9

Well today in 6th period science i worked on the computers and on the gizmos. the three gizmos i worked on were: density experiment: slice and dice, density via comparison, and determining density via water diplacement. at www.explorelearning.com. in my opinion the water displacement gizmo was the hardest.

diatomaceous earth with glacier expirement

I recently conducted an experiment on the affects of glacier runoff being related to erosion of earth and the creation of rivers. to test this my group members and I used a giant ice cube and a plastic tub with about a quarter inch layer of diatomaceous earth at the bottom. we hypothesized that the runoff would only create one small river. We started the experiment by propping the tub up at one end and placed the ice cube on it. we started waiting and soon enough we had runoff creating one large river down the middle, and several smaller tributaries along the way.

making rivers

we made a tiling system to prevent erosion. the tiling would prevent over flow water. the water will flow in the tile and go into a pond or a stream.

earth project

during the diotomacious earth project i learned that rivers can be formed many ways. such as glaciers, running water, or and earthquake. for the project all of the students got a bucket of diotomacious earth, and an idea. then all of us had to test our ideas with the earth.

Science 9 River Formation Expiraments

We tested erosion for our first river formation test. We took the sand and we piled it up on one side forming a downhill slope. Then, we took a graduated cylinder and poured water down the slope and observed that the water split off into two different streams but it didn't have enough room to join back together. I concluded that rain could possibly form a river under the correct circumstances.

We also tested the effects an earthquake would have on river formation. We used the magnets in the dieatomaceus earth and used the magnetic machine to spin the magnets and simulate what an earthquake would do. All it did was create small dips in the surface so it most likely wouldn't be able to create a stream, but it could help to start a pond or lake.
