river formations

on Tuesday, September 20th, we did river formations. at first, our experiments didn't work out so great. but we eventually got the hang of it.

we had to write down the experiment, procedure, hypothesis, and our conclusions. we did 2 experiments. we tried underwater springs, and mudslide.

underwater springs: experiment #1.

Procedure: first, we took a bin of rocks, and put a small plastic tube underneath the rocks. my hypothesis was that it was going to come up from under the rocks and form a path. once we turned the water on, nothing happened for a moment. we looked closer, and saw that the water was running under the pebbles. it didn't form a path above the rocks.

mudslide: experiment #2.

Procedure: we used a container of sand/dirt, and buried the plastic hose underneath the sand. my hypothesis was that the water would flow down, carrying the mud with it. we observed it closely, and the hypothesis was right. the water flowed down the slope, carrying the mud along.
