Spec & Goals 3 min

AQA Spec 3.8 · Ethical, legal & environmental impacts (whole unit)

By the end of this lesson you can:

  1. Revise and self-check the whole of Unit 8, spotting your weak topics.
  2. Answer exam questions — including extended "Discuss" responses — for the marks on offer.
  3. Make a focused revision plan that targets the topics you got wrong.

Warm-Up — command words & the paper 5 min

This is the last lesson of Unit 8 — and the last unit of the course. First, know the exam.

Command words tell you what to do

Command wordWhat it demands
State / NameA word or short phrase (e.g. the correct Act).
DescribeSay what something is, with detail.
ExplainGive reasons — the how or why.
DiscussBoth sides, across lenses and stakeholders, plus a reasoned conclusion.

Key Concept — your Unit 8 spec checklist 14 min

Tick each spec point. If you cannot do one, that is a topic to revise tonight.

Spec pointYou should be able to…
Types of impactName the five lenses (ethical, legal, cultural, privacy, environmental); define stakeholder.
PrivacyExplain how data is collected and the privacy benefits vs risks.
Ethical & culturalExplain the digital divide, misinformation, bias, censorship.
Data Protection Act 2018State what it protects; give its principles.
Computer Misuse Act 1990Describe its three offences (hacking & malware).
Copyright, Designs & Patents Act 1988Explain what it protects and infringement.
Software licensingCompare open source and proprietary.
EnvironmentExplain e-waste, energy use, and how to reduce impact.
"Discuss" techniqueStructure a balanced, reasoned extended answer.

Worked Example — a full multi-part question 12 min

Here is one question with three parts. We earn the marks aloud.

Part (a) — Name the law broken when someone spreads a virus that deletes files. [1 mark]

The Computer Misuse Act 1990 (unauthorised modification) (1).

Part (b) — Describe two principles of the Data Protection Act 2018. [2 marks]

Data must be kept secure (1); and used only for the specified purpose it was collected for (1).

Part (c) — Discuss the environmental impacts of replacing devices frequently. [6 marks]

Benefits: newer devices can be more energy-efficient. Drawbacks: more e-waste (toxic in landfill), more mining of rare materials, more manufacturing energy. Reduce by recycling, repairing and extending device life. Conclusion: frequent replacement's footprint usually outweighs efficiency gains, so reuse is greener.

Try It Yourself — timed mini-paper 12 min

These questions span the whole of Unit 8. Match your answer to the command word and the marks.

State[1 mark]

State which law controls how organisations handle personal data.

Mark scheme

Discuss[6 marks]

A hospital introduces wearable devices that send patients' health data to doctors. Discuss the impacts on stakeholders.

Mark scheme

Levels-marked (up to 6). Balanced points, e.g.:

  • Benefits — earlier diagnosis, continuous monitoring, fewer hospital visits (patients, doctors).
  • Concerns — privacy/security of sensitive medical data, reliance on devices, who else can access it (insurers), digital divide.
  • Mention the Data Protection Act and a reasoned conclusion for top marks.
