🎯 Aim
Today you will learn what Artificial Intelligence is, how AI systems use data to find patterns and make predictions, and why humans need to use AI responsibly.
💡 Be Inspired
Artificial Intelligence is already part of everyday life. It can help computers recognise pictures, understand speech, recommend videos, translate languages and answer questions.
Watch the video carefully. As you watch, think about this question: What makes Artificial Intelligence different from an ordinary computer program?
👀 Check It Out
Let's take a closer look at how an AI system can use data, patterns and predictions.
Your teacher will demonstrate the process using simple examples. Watch carefully and think about what happens at each stage.
💻 Do It Yourself
Now it is your turn to explore how Artificial Intelligence can use data to find patterns and make predictions.
Complete the Code.org AI and Data activity. You will work through a series of challenges where you sort data, make predictions and discover how computers can learn from examples.
Work through the Code.org activity carefully.
1. Explore the data — Look at examples that have already been sorted.
2. Find the pattern — Think about why the items have been placed into different groups.
3. Make predictions — Use what you have learned to predict where new items should go.
4. Test your thinking — Try sorting data yourself and see whether your partner can work out your rule.
As you work, ask yourself:
What patterns can I see?
What information am I using to make my prediction?
What happens if I do not have enough examples?
Could my prediction be wrong?
⭐ Extension
Now think beyond the activity. You have seen how a computer can use examples to find a pattern and make a prediction. But what happens when the examples are limited or do not give the computer enough information?
Imagine you are training an AI system to sort objects into two groups.
You give the AI lots of examples and it finds a pattern. It then uses that pattern to make predictions about new objects.
Now imagine that you only give it a few examples, or that your examples are all very similar.
What could happen?
Think about:
• Could the AI find the wrong pattern?
• Could it make an incorrect prediction?
• Could it struggle with something it has never seen before?
• How could you improve the data you give it?
Explain to a partner why more useful and varied data can help an AI system make better predictions.
Then explain why more data does not automatically mean better data.
Try to use these words in your explanation: data, pattern, prediction, example and accuracy.
A computer does not simply "know" the correct answer. It uses the information and examples it has been given.
If the examples are incomplete, limited or unhelpful, the pattern may not represent the real world accurately.
Good AI depends on good data and careful human thinking.
🏆 Finished!
Well done! You have completed your Artificial Intelligence lesson.
You have learned that AI systems can use data to find patterns and make predictions, but that AI can make mistakes and needs responsible human users.
