Lesson 3 & 4

Exploring Models for Energy Transfer and Transformations

Overview

Exploring Models for Energy Transfer and Transformations

Throughout this lesson series, students will be introduced to the law of conservation of energy. Using the example of a Rube Goldberg machine, students explore how usable energy is reduced during energy transfer and transformation such that the system is not 100 % efficient. Students will require ready access to ICT at a whole-class, small-group and individual level as well as materials to construct their Rube Goldberg machine.

Lesson Objectives

Students will:

  • Investigate and compare energy changes in examples such as car crashes, pendulums, lifting and dropping of objects.

Evidence of Learning

Can the student:

  • Model energy interactions using simple experiments
  • Explain energy transfer and transformations in these experiments using written language and diagrams.

Example Learning Sequence

  • Investigation of simple experiments to model energy transfer and transformations
  • Construct a Rube Goldberg machine
  • Identify all the energy transfers and transformations that occur to achieve the task as well as the losses of efficiency.
