JHS3 Science · Term 2 Week 11: Conversion and Conservation of Energy

Lesson notes

Indicator: B9.4.3.1.1 - Describe how energy can be converted from one form to another and show how conservation of energy occurs.

By the end of the lesson, learners can:

Define energy conversion and energy conservation in their own words and state the key difference between the two concepts.
Identify and describe at least five examples of energy conversion in everyday life, naming the initial and final forms of energy for each.
State the law of conservation of energy and explain what it means using a simple example.
Trace the energy conversions that occur in common Ghanaian devices and systems, such as a torch, an electric iron, or a water heater.
Demonstrate, through a simple activity, that energy is not lost but changes form, and account for where “lost” energy goes.
