The Power of Switches: Can They Do More?

The Power of Switches: Can They Do More?

Learning Objective

Understand the different functions of switches in circuits and be able to construct simple circuits and use symbols to represent the components.

What do you already know about switches in circuits?

Prior Knowledge

Discuss with the students their prior knowledge of electricity and circuits. Ask questions to gauge their understanding.

Circuit Construction

Instruct students to build a series circuit with a switch and a bulb or buzzer. Challenge them to draw a circuit diagram of their creation.

Switch Function

Explain how the switch works in the circuit and ask students to provide their understanding of its function.

Types of Switches

Show images of different switches found in common appliances and challenge students to describe and compare their functions.

Electric Toothbrush

Discuss the simple on/off switch that operates a small motor in an electric toothbrush.

Handheld Vacuum

Describe the trigger switch of a handheld vacuum that operates both the suction and a rotating brush.

Oven Switch

Explain the multiple functions of an oven switch and its various modes.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
