Learning Goals
5 minBy the end of this lesson you can:
- Name at least three AIs you use in everyday life.
- Describe the job each one does in a few words.
- Explain that all of them learned from data.
Warm-Up · Already This Morning?
8 minLast lesson we learned that a machine is "smart" when it learns from examples.
Which of these do you think used AI this morning?
- Your phone unlocking when it saw your face
- A toaster popping up the toast
- An app suggesting the next video to watch
- A torch turning on when you pressed the button
Reveal the thinking
Face unlock and video suggestions learned from data — your face, your past choices. That makes them AI.
The toaster and torch follow fixed rules. Same press, same result, every time. Not AI.
New Concept · The Invisible Helpers
18 minAI is mostly invisible
When we think of AI we picture talking robots. But most AI has no face at all.
It hides inside apps and devices as a quiet helper that makes a guess for you.
Where you meet AI every day
- Recommendations — YouTube, TikTok and Spotify guess what you will like next.
- Voice assistants — Siri and Google understand what you say.
- Photos — your gallery groups pictures of the same person.
- Maps — traffic predictions pick the fastest road to Ipoh.
- Translate — Bahasa Melayu to English in a tap.
- Spam filters — junk mail is caught before you see it.
- Games — enemies that play smarter the more you play.
Every one of these learned its job from data — lots of examples of what people watched, said, or clicked.
These helpers make guesses, and guesses can be wrong. A recommendation is a suggestion, not a command.
Worked Example · How "Up Next" Knows
18 minAiman opens a video app and the "Up Next" list already looks tempting. How?
Step 1 — It collected examples
The app watched what millions of people viewed, one video after another.
Step 2 — It learned a pattern
People who watched a sepak takraw clip often watched football tricks next. That is a pattern.
Step 3 — It made a prediction
Because Aiman just watched sepak takraw, the app predicts he might like football tricks — so it puts them next.
Nobody typed a rule for Aiman. The app learned from everyone's choices, then guessed his.
Try It Yourself
20 minUse your worksheet. These are thinking tasks — no computer needed.
List five AIs you have used this week. Next to each, write the job it does in a few words.
Hint
Think phones, video and music apps, games, maps, photos, and online shops.
For three AIs from your list, write what examples (data) each one probably learned from.
Hint
A music app learns from "songs many people played one after another".
Mini-Challenge · AI Scavenger Hunt
12 minHunt around your classroom, home or phone for AI in action.
Find three different kinds of AI — for example one recommender, one that sees or hears, and one in a game.
It works if for each one you can name the job it does and guess the data it learned from.
Show one example find
Photos app — face grouping. Job: gathers pictures of the same person. Learned from: many photos of faces. Kind: a vision AI.
Recap
5 minAI is all around us — usually invisible, inside apps and devices. Each one does a job by guessing, and each one learned that job from data.
Vocabulary Card
- recommendation system
- An AI that guesses what you might like next, from what people chose before.
- virtual assistant
- An AI you speak or type to, like Siri or Google Assistant.
- everyday AI
- The hidden AI in apps, phones and games we use without noticing.
Homework · One-Day AI Diary
≤ 20 minFor one whole day, jot down every time you meet an AI. For each, write the time, the app or device, and the job it did.
Aim for at least five entries. Bring your diary to the next lesson.
Just watch and write — no need to sign in to anything. Never type personal details into an app.
Sample · AI Diary
- 7:10am — Phone face unlock — opened my phone by seeing my face.
- 7:40am — Maps — picked the fastest route to school.
- 1:00pm — Video app — suggested the next clip to watch.
- 6:30pm — Keyboard — predicted the next word as I typed.
- 8:00pm — Music app — built a playlist it thought I'd like.
Yours will be different — any five honest entries with the job each AI did are perfect.
