Waterwheels and Waterpower Experiment

Grades:

4-12

Objective:

Learn how waterwheels operate and how they serve as a source of power.

Method:

Students will build a waterwheel and use it to conduct a waterwheel experiment.

    Materials:

  • 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
    • 1 rubber band
    • 1 round piece of paper
    • Scissors
    • Stapler
    • A water source, such as a faucet or hose

    Time:

  • Preparation Time: 15 minutes
  • Class Time: 40 minutes

    Procedure:

  • Divide students into groups of two or three.
  • Give each group a copy of the instruction sheet.
  • Ask the groups to use the instructions to construct their waterwheels.
  • Use the water source to test the waterwheel.
  • Ask each group to work together to answer the questions on the “Thinking About Your Waterwheel” sheets.

    Assessment:

  • Ability to follow directions
  • Completed experiment
  • Class participation (speaking and listening)

    NYS Learning Standards:

  • ELA Standard 1
  • Math, Science and Tech. Standard 1
  • Math, Science and Tech. Standard 4
