Assessment

1. Have students, either individually or in teams, propose a theory in answer to the questions: “How does the speed of the current affect the type of sediments that are carried and deposited by a river? When water moves quickly, what happens? When water moves slowly, what happens? Why?”

Going Further

1. Bring the conclusions of this experiment into the real world. How are different sediments distributed at a real creek? What causes the variance? See the Sediment Study Project for a detailed description.
