SHS2 Engineering · Semester 1 Week 18: Circuits and Machines

Lesson notes

Learning Objectives

Indicator: 2.2.1.LI.1 - Explain the functions of the basic components of analogue electronic circuits.

By the end of the lesson, learners can:

Identify at least five basic components of analogue electronic circuits (resistor, capacitor, diode, transistor, inductor) from physical samples or images.
State the function of each basic component in their own words, citing at least one practical use for each.
Distinguish between active and passive components, giving two examples of each.
Explain how a given component affects the behaviour of a simple analogue circuit (for example, how a resistor limits current or a capacitor stores charge).
Respond respectfully to questions about their findings during group presentations, showing tolerance and open-mindedness as they discuss component functions.

Exemplars (from the NaCCA curriculum)

Initiating Talk for Learning: In different task groups, each group researches the functions of a particular basic component of analogue electronic circuits. Learners share findings with the class and take comments and criticisms in a tolerant manner.
Experiential Learning: Learners watch videos on the uses of basic analogue electronic circuit components and share observations with the whole class

Assessment (2.2.1.AS.1). The document marks these depth-of-knowledge levels for this indicator: Level 2 Skills of conceptual understanding; Level 3 Strategic reasoning.

Teaching and Learning Resources:
