Lesson Content

Parts of a Computer – Speaker

A speaker is a device that produces sound from a computer. It works by converting electrical signals into sound waves. Sound is produced when it is indeed connected to a computer.

Features of a Computer Speaker

• Volume control:

  This lets you control how loud the sound is.

• Power button:

  This turns the speaker on or off.

• Audio input:

  This is where you plug the speaker into the computer.

• audio output:

  This is where the sound comes from.

Differentiation

For pupils who need more support, the teacher will provide one-on-one assistance.For pupils who grasp the concepts quickly, they can be challenged with additional questions about other computer parts.

Evaluation

1. What is a computer speaker?
2. Name three features of a computer speaker.
3. How does a computer speaker make sound?
4. Why is a speaker vital for a computer?

Observation

• Pupils’ participation in discussions
• Pupils’ ability to identify the features of a speaker
• Pupils’ understanding of how a speaker produces sound

Conclusion

to conclude the lesson,the teacher will summarize the key points about computer speakers and answer any remaining questions from the pupils. The teacher will then assign homework, asking pupils to draw a picture of a computer speaker and label its parts.
