River formation experiment!!

Experiment #1:

This was a very interesting experiment. My group (Wyatt, Meg, Neal, myself) came up with the hypothesis of this: We believe that people affect the formation of a river. We figured this because of all the pollution, litter, construction, etc. going on all over the world. We began our experiment. We mixed up the diatomaceous earth first and foremost. Then, we placed toy structures, people, and cars. After pouring water over the diatomaceous earth, we observed. The objects in the earth caused small rivers to form from them. In conclusion, our hypothesis was correct, and people do affect the formation of rivers. We were not surprised by the outcome of his experiment. We figured exactly what happened!

Experiment 2:

In this experiment, my group tested how earthquakes affect river formation. Our hypothesis was this: We believe that earthquakes affect the formation of rivers. Here's our experiment: First, we mixed up the diatomaceous earth until it was nice and smooth once again. Next, we buried magnetic stirrers in the earth. After this, we put the container over the stirring machine, creating an effect much like seismic waves. We stopped the machine, and made observations. We noticed that there were no rivers or streams that were made. Really, there weren't even "lakes" or "ponds." I would describe the change more as some kind of ground level difference such as a crater/rift of some sort. In conclusion, our hypothesis was incorrect. Earthquakes really don't affect the formation of a river. We were very surprised by the outcome. We thought it would create large cracks and lakes, but no. It barely even created a breach in the earth.
