SS 1 Third Term

Lesson objectives

By the end of the week, learners should be able to:

1. Name five ethics rules for computer use.
2. Name five common virus types and their infection methods.
3. Explain why anti-virus software matters.
4. Describe one safe-practice habit for every school lab day.
5. State why schools teach ethics before programming.

Key vocabulary

• Ethics: responsible principles governing computer use.
• Rule: a standard behaviour expected of every user.
• Virus: a malicious programme replicating without permission.
• Infection: the entry and spread of a virus through a host.
• Anti-virus: software detecting and removing malicious programmes.
• Safe practice: behaviour reducing risk during computing work.
• Replication: copying itself into other programmes or files.
• Host: a programme or file carrying the virus.

Common misconceptions

• "Viruses appear only from clicking unknown links." Viruses enter through removable drives and email attachments too.
• "Ethics is optional outside school." Learners face ethical challenges wherever they use devices.
• "Anti-virus alone prevents all viruses." Safe habits matter as much as installed software.

Teacher activities

1. Starter: display a virus infection card and ask where a safe practice would prevent infection.
2. Name five ethics rules and demonstrate each one.
3. Introduce five common virus types and their infection methods.
4. Demonstrate activating anti-virus software on a test machine.
5. Name one safe-practice habit for every school lab day.
6. Close with the infection-scenario task and exit question.

Student activities

1. Answer the starter and state where the infection might enter.
2. Name five ethics rules in their own words.
3. Name five virus types and state each infection method.
4. Describe why anti-virus matters without prompting.
5. State one safe-practice habit for every school lab day.
6. Solve the infection scenario with a corrective action.
7. Answer the exit question in one sentence about why ethics come before programming.

Practical / learning evidence

An ethics rules sheet, a five-virus-type worksheet and a safe-practice checklist. Submit all three for marking.

Resources and preparation

Printed rules cards, virus scenario cards and an activated anti-virus demonstration. Monitor test machines carefully and disable camera capture during demo. Provide an offline alternative set of cards.

Assessment for learning

Inspect the ethics rules for five correct standards. Mark the virus worksheet for accurate type names and methods. Check the safe-practice checklist for a repeated habit. Flag any learner who says viruses come only from links.

Inclusion and homework

Provide the rules cards prelabelled for learners who need scaffolding. Allow oral virus identification. Extend confident learners with seven virus types and two infection vectors. Homework: list two places a virus could enter your school lab and state the safe action for each.
