Lesson notes

Learning Objectives

Indicator: B4.4.2.2.1 - Identify the basic components of electronic circuits

By the end of the lesson, learners can:

Name at least four basic electronic components (connecting wire, battery/dry cell, switch, LED) when shown the physical item or a picture.
State the function of each basic component in a simple circuit.
Connect a battery, switch, LED and connecting wires in a complete circuit to make the LED light up.
Draw and label a simple circuit diagram showing the battery, switch, LED and wires.
Suggest at least one alternative material that can serve as a connecting wire in the absence of copper wire.

Exemplars (from the NaCCA curriculum)

- Learners are put into groups and each group is provided with connecting wires, batteries (dry cells), switches and LEDs (of different colours).
- Learners are assisted to identify the various components provided.
- Learners observe a demonstration on how to connect the components to light the LED.
- Learners are guided to connect the components to make the LED produce light.
- Engage learners to discuss the use of each component
- Learners draw the circuits they have connected.
- Learners suggest other materials that can be used in the absence of the connecting wire.
- Learners act as electrons flowing in a circuit through the classroom. Learners act out the role of various components (resistor, capacitor, etc) in the circuit.
NB: Build a stock of electronic components from discarded electronic gadgets such as radio and TV sets.
