SHS2 Design And Communication Technology · Semester 2 Week 9: Building Drawing

Lesson notes

Learning Objectives

Indicator: 2.3.1.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 two key differences between them.
Identify and name at least five components commonly found in electrical circuits and five components commonly found in electronic circuits, explaining the function of each.
Sort a given list of components and devices into electrical circuits or electronic circuits, justifying each choice with a reason.
Construct simple working models of both an electrical circuit and an electronic circuit using low-cost materials, and explain how each works.
Analyse a given circuit diagram and classify it as electrical or electronic, defending their classification with evidence from the components shown.
