Learn how waterwheels operate and how they serve as a source of power.
Students will build a waterwheel and use it to conduct a waterwheel experiment.
- A copy of the Experiment Instruction Sheet for each group
- A copy of the Thinking About Your Waterwheel for each student
- One set of materials for each group of students:
- 2 large paper or disposable plastic plates (plastic is better than paper)
- Small paper or plastic cups
- 2 pencils or wooden dowels
