Year 7 online safety lessons: AI in the classroom and everyday safety
Year 7 starts with the AI tools pupils meet in school and the devices, games and trends in their everyday lives.
AI chatbots: tool, not friend
- 2 minHook
- Show a chatbot reply that asks for your name, school and age. Would you answer?
- 4 minLearn
- Chatbots are not people. What you type can be stored and used to train them. Most mainstream chatbots have a minimum age (often 13) and the school has its own rules on AI tools.
- 3 minDiscuss
- Sort cards: safe or not safe to type into a chatbot (homework question, home address, a photo of yourself, a worry).
1 min · key messageNever type anything into a chatbot that you would not post publicly.
Real or fake? AI images
- 2 minHook
- Show two images side by side. Which one was made by AI?
- 4 minLearn
- AI can create realistic images, video and text. Clues (hands, text, lighting, backgrounds) help, but you cannot always tell. Use a reverse image search and check the source.
- 3 minDiscuss
- Quick-fire spot-the-fake assessment, then discuss: why might someone post a fake image?
1 min · key messageIf it looks too perfect or too shocking, check before you share.
AI and homework: help or cheating?
- 2 minHook
- “AI wrote my homework and I got full marks.” Is that OK?
- 4 minLearn
- The school's rules on using AI. AI makes mistakes and can make things up. Using AI to explain or assess you is different from handing in its work as your own.
- 3 minDiscuss
- Sort examples into helping or cheating (explain a topic, write my essay, check my spelling, answer the test).
1 min · key messageUse AI to help you learn, never to do the learning for you.
Smart devices: who is listening?
- 2 minHook
- “Hey…” Who has a smart speaker, smartwatch or connected toy at home?
- 4 minLearn
- Smart devices use microphones, cameras and location. They can record what you say and send data to companies. Privacy settings and parental controls limit this.
- 3 minDiscuss
- In pairs, list the data a smart speaker might collect in one day and who could see it.
1 min · key messageSmart devices are always collecting data, so check the settings.
Viral challenges and trends
- 2 minHook
- Show a (fictional) viral challenge post with millions of views.
- 4 minLearn
- Trends spread fast because algorithms reward views. Some challenges are dangerous, fake or designed to scare. Do not search for them or pass them on; tell a trusted adult.
- 3 minDiscuss
- Apply the three checks to the trend: Is it safe? Is it kind? Is it true?
1 min · key messageDo not join in or share a trend until you have checked it is safe, kind and true.
Gaming, age ratings and age checks
- 2 minHook
- “Why does this game want to scan my face?”
- 4 minLearn
- Age ratings (PEGI) and platform age checks exist to protect younger players. Chat, friend requests and in-game purchases bring risks. Use privacy and chat settings, block and report.
- 3 minDiscuss
- Scenario: a player you don't know offers free in-game currency if you add them. What do you do?
1 min · key messageSettings, blocking and reporting keep your games safe and fun.
Year 7 end point. Pupils can explain why personal information should not be shared with AI chatbots, check whether an image or trend is real and safe before sharing, follow the school's rules on AI, and manage the settings on their devices and games.
Year 8 online safety lessons: deepfakes, AI companions, scams and algorithms
Year 8 moves AI into pupils' own lives: the people they see online, the feeds they scroll and the messages they receive.
Deepfakes of real people
- 2 minHook
- A video shows a famous footballer saying something shocking. It looks real. Is it?
- 4 minLearn
- Deepfakes use AI to swap faces or clone voices of real people. They are used for jokes, scams and bullying. Creating or sharing fake images of someone without consent can cause serious harm and may be a crime.
- 3 minDiscuss
- Pairs: if a deepfake of a classmate appeared in a group chat, what should you do, and what should you not do?
1 min · key messageDo not create or share fakes of real people; screenshot, report and tell an adult.
AI companions and ‘AI friends’
- 2 minHook
- “My AI friend always agrees with me and is there 24/7.” What could go wrong?
- 4 minLearn
- Companion chatbots are designed to keep you talking. They can feel caring but they do not understand you, can give harmful advice and collect what you share. Real friends and trusted adults are the right people for worries.
- 3 minDiscuss
- Compare an AI companion with a real friend: what can each one actually do for you?
1 min · key messageAn AI that always agrees with you is not a friend; talk to real people about things that matter.
Algorithms and your feed
- 2 minHook
- Why does your feed show you more of what you watched last night?
- 4 minLearn
- Recommendation algorithms learn from likes, watch time and searches to keep you scrolling. This can create echo chambers and push more extreme or upsetting content. You can reset, mute, select “not interested” and set time limits.
- 3 minDiscuss
- Map how one video watched to the end could change a feed over a week. How would you break the loop?
1 min · key messageYou can train your feed; do not let your feed train you.
AI-powered scams
- 2 minHook
- Play a (fictional) voice message from a ‘parent’ asking for money urgently.
- 4 minLearn
- AI makes scams more convincing: cloned voices, perfect-spelling phishing messages and fake giveaways. Warning signs are urgency, secrecy and requests for money, codes or passwords. Check using a different, trusted channel.
- 3 minDiscuss
- Spot the scam: rank three messages from most to least suspicious and explain the clues.
1 min · key messageIf it is urgent, secret or asks for money or codes, stop and check another way.
Filters, edits and body image
- 2 minHook
- Show a before-and-after AI beauty filter. Which is ‘real’?
- 4 minLearn
- AI filters and editing apps change faces and bodies in seconds. Constantly comparing yourself with edited images can affect self-esteem. Many influencers' images are filtered, edited or AI-generated.
- 3 minDiscuss
- Discuss: how might seeing only filtered images every day change how someone feels about themselves?
1 min · key messageMost of what you see is edited; compare less and be kind to yourself and others.
Your digital footprint and AI
- 2 minHook
- “I deleted it, so it's gone.” True or false?
- 4 minLearn
- Posts, photos and location can be screenshotted, saved and used to train AI. Old posts can be found by schools, employers and strangers. Review privacy settings, turn off location sharing and think before you post.
- 3 minDiscuss
- Audit a fictional pupil's profile: what could a stranger learn about them in 60 seconds?
1 min · key messageAssume anything you post is permanent and public.
Year 8 end point. Pupils can recognise deepfakes and AI-powered scams and know how to report them, explain why AI companions are not a substitute for real relationships, take control of their feeds and settings, and manage their digital footprint.
Year 9 online safety lessons: misinformation, AI bias, sextortion and the law
Year 9 widens the lens to democracy, fairness, extreme views, the law and pupils' rights online.
Misinformation, deepfakes and democracy
- 2 minHook
- A fake AI video of a politician goes viral the night before an election. What happens next?
- 4 minLearn
- AI makes it cheap and fast to produce fake news, images and audio at scale. Misinformation is false; disinformation is false on purpose. Lateral reading means checking other trusted sources, the original source and fact-checking sites.
- 3 minDiscuss
- Pairs: fact-check a (fictional) viral claim using lateral reading. What would convince you it is true?
1 min · key messageCheck the source and look for other trusted sources before you believe or share.
Bias in AI
- 2 minHook
- Facial recognition works well for some faces and badly for others. Why?
- 4 minLearn
- AI learns from data. If the training data is biased or incomplete, the AI's decisions can be unfair, for example in facial recognition, job shortlisting or content moderation. People must check and be accountable for AI decisions.
- 3 minDiscuss
- Discuss: should AI decide who gets a job interview? What checks would make it fairer?
1 min · key messageAI is only as fair as its data and the people who check it.
Influencers, algorithms and extreme views
- 2 minHook
- Show a (fictional) influencer clip promising ‘the truth they don't want you to know’.
- 4 minLearn
- Algorithms can push people towards more extreme content, including misogynistic, hateful or radicalising material. Warning signs include us-versus-them messages, blaming groups and pressure to keep it secret. Report concerns to a trusted adult.
- 3 minDiscuss
- Identify the persuasion techniques in the clip. Who benefits if you believe it?
1 min · key messageQuestion who is persuading you and why; extreme content is designed to hook you.
Sextortion, nude images and AI
- 2 minHook
- “Someone has made a fake image of me and is threatening to share it.” What should they do?
- 4 minLearn
- Creating, sharing or possessing sexual images of anyone under 18 is illegal, including AI-generated images. Sextortion is blackmail: do not pay or send more, keep evidence, block and tell an adult. Report Remove (Childline and IWF) and CEOP can help.
- 3 minDiscuss
- Agree a step-by-step plan: what to do in the first 10 minutes if this happened to a friend.
1 min · key messageIt is never your fault; do not pay, keep evidence and get help straight away.
AI, creativity and copyright
- 2 minHook
- An AI-made song wins a competition. Who owns it: the AI, the user or the artists it learned from?
- 4 minLearn
- Generative AI is trained on existing work, which raises questions about copyright, credit and consent. Using AI openly and honestly is different from passing off work as your own. Always check rules on AI use for coursework.
- 3 minDiscuss
- Debate: should AI-generated work be labelled? Should artists be paid if their work trains AI?
1 min · key messageBe honest about when you use AI and respect other people's work.
Your rights and the law online
- 2 minHook
- Who is responsible for keeping you safe online: you, the platform or the government?
- 4 minLearn
- The Online Safety Act 2023 requires platforms to protect children, including age checks. UK GDPR gives you rights over your personal data. The Computer Misuse Act makes hacking illegal. You can report harmful content to platforms and to Report Harmful Content.
- 3 minDiscuss
- Match scenarios to the law or right that applies, then decide who to report to.
1 min · key messageYou have rights online; know them, use them and report harm.
Year 9 end point. Pupils can evaluate AI-generated misinformation using lateral reading, explain how bias and algorithms shape what they see, recognise radicalisation and sextortion warning signs and know where to get help, use AI honestly, and describe their key rights under UK law.

Teaching the sensitive lessons
Lessons on AI companions, body image, extreme views and sextortion can raise disclosures. Check them with your DSL and PSHE/RSHE lead before teaching, and make sure pupils know who to talk to afterwards. Help for pupils: Report Remove (Childline and IWF), CEOP and Report Harmful Content. Review the examples each September so they stay current.
Online safety lessons FAQ
What are 10-minute online safety lessons?
They are short, ready-to-teach online safety lessons for KS3. Each one follows the same four steps: a 2-minute hook, 4 minutes of direct teaching, 3 minutes of discussion and a 1-minute key message pupils say back or write down. There are six lessons a year, one per half term, for Years 7, 8 and 9.
When should I teach them?
They are designed for lesson starters, tutor time or the last ten minutes of a Computing lesson. Teaching one each half term keeps online safety current all year rather than leaving it to a single unit in September.
Do the lessons cover AI and deepfakes?
Yes. Every lesson brings in current AI and emerging technology: chatbots, AI-generated images, deepfakes, AI companions, AI-powered scams, recommendation algorithms, bias in AI and AI-generated indecent images, alongside smart devices, gaming and viral trends.
Do they meet the RSHE 2025 guidance?
Each lesson is mapped to the revised RSHE statutory guidance (DfE, July 2025; statutory from 1 September 2026), including the new online content on AI chatbots, deepfakes, scams, fake accounts, misogyny and incel culture, and the law on indecent images. The mapping uses topic headings, so check the exact wording with your PSHE/RSHE lead.
How do they link to the KS3 Computing curriculum?
Every lesson meets NC9 (using technology safely, respectfully and responsibly). Lessons also cover NC8 on trustworthy content, NC5 in the smart devices lesson and NC7 in the bias in AI lesson.
Is the Year 9 sextortion lesson safe to teach in ten minutes?
It is written to be taught calmly and factually, with a clear message that it is never the victim's fault and where to get help, including Report Remove (Childline and IWF) and CEOP. Check sensitive lessons with your DSL and PSHE/RSHE lead before teaching, and make sure pupils know who to talk to afterwards.
How do you keep the examples up to date?
The scheme is reviewed every September using current trends and pupil voice, so the hooks and examples stay relevant to what pupils are actually seeing online.
Check what pupils actually understood
Pair the lessons with Teach io assessments. Every wrong answer is mapped to the misconception behind it, so you see who still thinks a chatbot is a friend, and why.
