Lesson 5 - 6

Explain water wheels and wind mills

Lesson Overview

Explain water wheels and wind mills

Using the example of water or wind, students explore how usable energy is transformed into useful energy through a simple device. They will construct and conduct performance tests on their device as well as investigate the effect of a variable on this performance. Students will require ready access to ICT at a whole-class, small-group and individual level.

Lesson Objectives

Students will:

  • Investigate the factors that determine performance of a wind mill or water wheel.

Evidence of Learning

Can the student:

  • Explain how a variable changes the performance of a water wheel or wind mill.

Example Learning Sequence

  • Start with a working wind mill or water wheel.
  • Collect baseline data of its performance by measuring the maximum weight that can be lifted.
  • Identify variables that could affect the performance.
  • Choose one variable to investigate.
  • Keeping all other variables the same make a series of tests with incremental changes to the chosen variable.
  • Collate results and graph the data.
  • Analyse the data to find the relationship between the variable and the performance.
