Introduction & Learning Objectives
Learning Objectives
Identify a real-world problem that can be solved using AI.
Define the specific inputs (data) an AI solution would need.
Describe the desired output or decision the AI should make.
Explain the main 'thinking' process or task of their proposed AI model in simple terms.
Sketch a simple user interface (UI) for their AI solution.
Apply the Problem-Input-Process-Output (PIPO) model to structure their AI project idea.
Have you ever wished your phone knew exactly what song you wanted to hear next, or that a game could create a new level just for you? 🤔 Let's learn how to design an AI that can do amazing things!
In this lesson, you won't be coding, but you'll be doing something just as important: being an AI architect! You will learn the...

Key Concepts & Vocabulary
TermDefinitionExample
Problem StatementA clear and simple sentence that describes the specific problem you want your AI to solve.My school friends have trouble deciding what movie to watch on Friday nights.
Input DataThe information or data that you give to the AI so it can make a decision. It's what the AI 'learns' from or 'looks' at.For a movie recommender, inputs could be: favorite genres (comedy, sci-fi), favorite actors, and movies the user has liked before.
AI Process (The 'Thinking')The main task or job the AI performs with the input data. It's the 'brain' of the operation.The AI will process the user's favorite genres and actors to find patterns and then search a movie database for movies that match those patterns.

Core Syntax & Patterns
The PIPO Design Model
Problem -> Input -> Process -> Output
Use this four-step model to structure your AI idea. First, clearly state the Problem. Second, decide what Input data the AI needs. Third, describe the Process the AI will perform. Fourth, define the final Output or result.
User-Centered Design Principle
Design for the user, not for the computer.
Always think about the person who will be using your AI. Is it easy for them to understand? Is the output helpful to them? The best AI solutions are the ones that are easy and useful for people.

Challenging
You are designing an AI to help Grade 7 students choose a book. Which PIPO combination best demonstrates both a specific design and a user-centered approach?
A.P: Help a student find a sci-fi book they will enjoy. I: Student selects 3 favorite sci-fi movies. P: AI finds books with similar themes. O: A recommendation of 3 books with their cover images and a short summary.
B.P: Find a book. I: User's name. P: Search the internet. O: A list of 1000 books.
C.P: Catalog all books. I: A picture of a library. P: AI uses magic to read the user's mind. O: The perfect book.
D.P: Recommend a book. I: The student's grade level. P: AI picks a random book from the Grade 7 reading list. O: The title of one book.
Challenging
A team proposes an AI app to 'improve a person's life.' The user inputs 'their goals,' and the AI's process is to 'figure out a strategy.' The output is 'a better life.' Which critique BEST identifies the multiple flaws in this design based on the lesson?
A.The problem is too big, the inputs/outputs are vague, and the process is 'magical AI thinking'.
B.The user interface will be difficult to design, and the AI will be too slow.
C.The input is too personal, and the AI might give bad advice.
D.The problem is not interesting, and the output is not guaranteed.
Challenging
The 'Safe Route Finder' AI is designed to find the safest walking route based on street lighting. To significantly improve this AI's 'Process' and make its 'Output' more trustworthy, what would be the most valuable NEW 'Input Data' to add?
A.The user's walking speed.
B.The current weather conditions.
C.Real-time, user-reported data on things like broken streetlights or suspicious activity.
D.The user's favorite color for the route line on the map.
