Stand Firm

As our final project for a high school earth science class, a friend and I built a stream table. With extensive help from my father, we built a long plywood box with a hinge in the middle. Then we lined it with plastic and filled it with sand. At one end we attached a hose. At the other end was a drainage hole. After assembling all of it, we raised one end of the stream table, turned on the water, and watched as it created a path directly to the hole at the other end. The next part of the experiment was to place a rock in the stream and watch how it changed the path of the water.
