Lesson notes

Learning Objectives

Indicator: 2.3.2.LI.1 - Distinguish between electrical circuit and electronic circuit.

By the end of the lesson, learners can:

Define electrical circuit and electronic circuit in their own words, stating at least one key difference between them.
Classify given circuit components as belonging to either an electrical circuit or an electronic circuit, justifying their choices with reasons.
Compare the function of electrical circuits and electronic circuits, explaining what each type of circuit is designed to do.
Construct a simple table to organise the differences between electrical circuits and electronic circuits under the headings of components, function, and examples.
Critically evaluate a given circuit diagram and decide, with reasons, whether it represents an electrical or electronic circuit.

Exemplars (from the NaCCA curriculum)

Managing talk for learning: With the aid of real objects, models and board illustration, learners brainstorm to come up with the difference between electrical circuits and electronic circuits. Assist learners to outline the components in electronic and electrical circuits and explain their functions.
