Lesson notes

Learning Objectives

Indicator: B3.4.2.1.1 - Identify different sources of electrical energy

By the end of the lesson, learners can:

Name at least four different sources of electrical energy, including hydro, solar, thermal, and batteries
Match each source of electrical energy to where it is commonly used in Ghana (e.g., Akosombo Dam, Aboadze Thermal Plant, solar panels, torch batteries)
Explain in simple terms how a dry cell (battery) produces electricity to light a bulb
Describe how electricity gets from a power plant to their home or school
Sort pictures or cards of electrical sources into renewable and non-renewable groups with teacher support

Curriculum details

Strand: Forces and Energy (Strand 4)
Sub-strand: Electricity and Electronics (4.2)
Content standard: B3.4.2.1 - Demonstrate knowledge of generation of electricity, its transmission and transformation into other forms of energy
Indicator: B3.4.2.1.1 - Identify different sources of electrical energy
Suggested placement: Term 3, Week 1 (Week 25 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.
Source document note: The official curriculum document has a fault in this entry, so the curriculum text above is transcribed exactly as printed:

indicator text - p.58: the page carries a bare "SUB-STRAND 1" heading in the content standard column and the real heading "SUB-STRAND 2.: ELECTRICITY AND ELECTRONICS" part-way down the indicator column; the bare one names nothing and is dropped

Exemplars (from the NaCCA curriculum)

- Before the lesson, let learners investigate to find-out where they get electricity for their home and school. e.g. Aboadze Thermal Plant, Akosombo and Bui Hydroelectric plants.
- Learners listen to a story on the history of how electricity was first produced.
- Learners watch a video or look at a poster on how electricity is produced from various sources. E.g. batteries, solar, hydro, thermal and generators.
- Learners demonstrate how to produce electricity from simple sources such as dry cells (batteries) to light a torch or a lamp.
- Ask learners to discuss the sources of the electricity they use at home
