Our class got assigned to use diatomaceous earth and form rivers. To do this we first needed to form a hypothesis. One of our hypothesis was to see if we lifted up the box of diatomaceous earth and poured water on it if it would form a little stream that later turned into a river. So to test this we patted down the diatomaceous earth and elevated one side of the box. Next we pured water onto it to form a river. Our conclusion was that our hypothesis was correct and it formed and river.
We also tried to form a river with animals tracks. Our hypothesise was to see if we made animal tracks in the diatomaceous earth and then elevate it and poured water on it if it would form a river. So to test this we once again patted down the diatomaceous earth and pressed our fingers in it to represent animals tracks. We then elevated it on one side and poured water on it. Our conclusion was that it form a river very fastly.
