A group of students conducted an experiment to test how water speed affects erosion. They hypothesized that the faster water flows, the more erosion will occur. The students poured the same amount of water down a stream table at three different rates without changing the slope. They found that erosion increased the faster the water flowed, with the most erosion occurring near the outlet tube when water speed was highest. The students concluded that their hypothesis was correct - faster water speeds lead to greater erosion.
