Real or fake? Deepfakes, cloned voices and AI scams

Students try to tell human texts from AI ones, then study scam message cards to spot the pressure tricks, and plan what to do, including a family safe word.

Students will be able to

  • explain that AI can copy voices, faces and writing well enough to fool people
  • spot four pressure tricks in scam messages: hurry, secrecy, money and codes
  • describe safe steps: stop, hang up, check through a known number, tell an adult
  • explain what a family safe word is and how to use it

Prepare

  • A projector and one teacher device with internet, or a few devices for pairs
  • The ManuAI page /play/lab/catch-the-bot loaded in advance (free, no account)
  • One set of six scam message cards per group (see the plan)
  • One worksheet per student

A fake video, photo or voice made with AI to look or sound like a real person.

Catch the bot, then catch the scam

The class plays /play/lab/catch-the-bot together, guessing whether ten short texts were written by a person or an AI, and finds it hard. Groups then read scam message cards and mark the pressure tricks, which show that the safest test is the pressure in a message, since fakes can look and sound real.

The 45-minute plan · 45 minutes

Warm-up6 min

Person or AI?

  • Open /play/lab/catch-the-bot on the projector. Read each text and let the class vote: person or AI.
  • Count the class score at the end. Ask: "Was it easy?"
  • Explain that AI can also copy a voice from a short clip and make fake videos of real people.
Activity18 min

Scam message cards

  • Give each group six cards. 1: "Mum, I dropped my phone, this is my new number. Send 2 million dong now, don't tell Dad." 2: "You won an iPhone! Pay 300,000 dong delivery within 30 minutes."
  • 3: A caller says he is a police officer, your family's account is linked to a crime, and you must move money to a safe account and keep it secret. 4: "Your bank: your account will be locked today. Reply with the OTP code we just sent."
  • 5: A blurry video call from a friend's account asking to borrow money for an emergency. 6: "Reminder from school: parents' meeting on Saturday at 8 am in room 7A."
  • Groups circle the pressure tricks on each card: hurry, secrecy, money, codes. They find that card 6 has none.
  • Share answers. Point out that the voice, the face or the friend's account can all be faked, while the pressure tricks stay the same.
Practice16 min

What would you do?

  • Write the safe steps on the board: stop, do not reply or send anything, hang up, call back on a number you already know, tell an adult.
  • Give the facts: police and banks never ask you to move money to a safe account. Nobody real needs your OTP code. For bank worries, call the official hotline printed on the back of the bank card. In danger, call 113.
  • Explain the family safe word: agree a secret word at home and ask for it if a call sounds strange.
  • Students complete the worksheet in pairs.
Wrap-up5 min

Pressure is the warning sign

  • Ask the class to say the four tricks together: hurry, secrecy, money, codes.
  • Suggest they tell their family about the safe word tonight. Offer the family printouts.
  • Hand out the exit ticket.

Teacher tips

  • Some students or families may have been scammed already. Keep the tone kind: scammers fool clever adults too, and telling someone quickly is the right thing to do.
  • Make sure the advice is exact: the bank's number is the one printed on the back of the card, never one given in the message. In an emergency, 113 is the police.
  • Mixed levels: stronger students can design a one-page poster of the four tricks for younger classes. Students who struggle with reading can work on the cards with a partner reading aloud.

Exit ticket answers

  1. Which message is most likely a scam? B. "Send me your OTP code in 5 minutes and don't tell anyone"
  2. Why can you not always trust a voice or video call, even if it looks and sounds like someone you know? A good answer: AI can clone a voice from a short recording and make fake video of a real face. Check by hanging up and calling back on a known number, or by asking for the family safe word.
  3. Someone on the phone says they are from your bank and asks you to move money to a "safe account". What is true? D. Real banks and police never ask this. Hang up and call the hotline on the back of the card.
