National Curriculum Links

Computing Programme of Study (Key Stage 4) – England

• Subject content:
  • “understand the concepts of confidentiality, integrity and availability”
  • “understand how to investigate and analyse digital security threats and risks”
  • “explain how cyber threats can impact hardware and software”
• Key stage 4 knowledge, skills and understanding:
  • “analyse the risks and threats posed by cyber security”
  • “understand measures to protect computer systems”

This lesson links explicitly to the national curriculum aims to understand risks and security threats to digital systems and their impact.

---

Learning Objectives (WALT)

• WALT identify common digital security threats including malware, phishing, and unauthorised access
• WALT describe how these threats affect system hardware and software performance
• WALT understand why digital security is essential for protecting data and system integrity

---

Success Criteria

By the end of the lesson, students will be able to:

• List and explain at least three types of digital security threats
• Give examples of how each threat can harm hardware or software
• Participate actively in discussion and activities, demonstrating understanding of security threats
• Use technical vocabulary correctly (e.g., malware, phishing, cyber attack, unauthorized access)

---

Resources Needed

• Large poster paper and markers
• Printed dyslexia-friendly fact sheets on malware, phishing, and access control
• Interactive quiz app or platform (e.g., Kahoot, Quizizz – teacher choice)
• Example phishing emails (simulated, carefully designed for awareness)
• Laptops/tablets (optional) for research or quiz participation
• Projector or smartboard for presentation

Lesson Structure

1. Starter (10 mins) – Engage and Activate Prior Knowledge

• Activity: Brainstorm: “What types of dangers do computers or digital devices face?”
• Write responses visibly on the board/poster paper. Use keyword prompts for dyslexic learners (also provide word banks).
• Briefly clarify through questioning the difference between physical dangers and digital security threats.

Differentiation:

• Support learners who find spelling tricky by providing printed keyword cards.
• Advanced learners can be asked to categorise threats into ‘hardware’ or ‘software’ impacts.

---

2. Input (15 mins) – Introduce Digital Security Threats

• Present a short teacher-led talk with slides covering:

  • Malware: viruses, ransomware, worms
  • Phishing: fake emails, scams, social engineering
  • Unauthorised Access: hacking, weak passwords, insider threat

• Use dyslexia-friendly fonts and coloured overlays on slides to assist reading ease.

• Provide printed fact sheets summarising key points for each threat.

• Explain impact on hardware (e.g., malware causing overheating, permanent damage) and software (e.g., corrupted files, stolen data).

Extension for advanced learners:

• Challenge them to think about how these threats could affect organisations differently than individuals.

---

3. Activity (20 mins) – Interactive Group Task: Spot the Threat

• Students split into pairs or triads (2–3 per group, maintaining 6 in total)
• Each group receives 3 case studies (short scenarios) describing a security incident.
• Task: identify the type of threat, explain the impact on hardware/software, and suggest one immediate measure to reduce the threat.
• Groups illustrate their findings on posters or digital slides (depending on available tech).

Differentiation:

• Provide sentence starters to scaffold explanations for learners needing support.
• Encourage advanced learners to include technical detail (e.g., ‘Trojan horse malware’, ‘phishing URL analysis’).

---

4. Plenary (10 mins) – Review and Reflect

• Groups share their findings with the class; teacher facilitates discussion, affirming correct answers and addressing any misconceptions.
• Conduct a quick interactive quiz (via Kahoot or printed quiz) to consolidate understanding. Questions focus on definitions, impacts, and examples of threats.

Success check: Students use thumbs up/down or mini whiteboards to answer, allowing rapid assessment of confidence.

---

5. Extension/Homework (optional)

• Research: Write a short paragraph on a recent cyber security attack in the news and describe what type of threat it was and its impact.
• Design a ‘digital security tips’ poster aimed at year 7 pupils, explaining how to avoid common threats.

---

Differentiation Strategies Summary

Learner Type	Strategy
Dyslexic learners	Dyslexia-friendly sheets, word banks, oral explanations, use of supportive visuals
EAL learners	Vocabulary support, paired/group discussions for oral practice
Advanced learners	Extension tasks, technical terminology, deeper implications of threats
SEN (cognitive)	Simplified scenarios, sentence starters, one-to-one support if possible

---

Assessment and Feedback

• Formative: Observation during group activities, participation in discussions, and quiz performance
• Summative (for later lesson): Short written assignment or digital portfolio entry describing threats

Teacher to provide written and verbal feedback emphasising correct use of terminology and logical explanations.

---

Reflection for Next Lesson (Lesson 2 Focus)

• Building on identified threats, next lesson will explore strategies to protect digital systems (e.g., authentication, encryption) in line with national curriculum content on safeguarding digital systems.

Summary

This lesson blends clear curriculum alignment, active learning, and inclusive teaching approaches, providing Year 10 students with a foundational understanding of digital security threats relevant to everyday technology use. Through multimodal delivery and scaffolded tasks, the lesson supports diverse learners and incorporates interactive elements designed to engage and 'wow' teachers seeking creative, dyslexia-friendly, and curriculum-focused lesson plans.
