Learning Objectives

Indicator: B7.4.2.2.2

By the end of the lesson, learners can:

Use the correct Ghanaian English names to identify the P-region and N-region of a P-N junction diode.
Explain in their own words what happens inside a simple circuit when the switch is closed and when it is opened.
Describe the role of the battery, the switch, and the LED in a complete electronic circuit and state how they depend on one another.
Work in small groups to dismantle a spoilt electronic gadget, name the visible parts, and sort them into components they can identify.
Present a clear oral explanation of how a switch controls the LED in a circuit, using correct and orderly speech.
