1. Click the green flag to start the project. 2. Click the Snackbot and it will ask you to input your snack. 3. Type the name of a snack into the chat box (example: “apple”). Press Enter to see how Snackbot responds. 3. Click the Snackbot again to try different snacks (like “carrot,” “pizza,” or “cookie”). Notice which snacks Snackbot calls healthy and which it calls unhealthy. Keep testing to figure out the rules. Want to make your own? Remix here: https://scratch.mit.edu/projects/1226651765
Purpose: This activity uses Snackbot to introduce students to foundational concepts in Artificial Intelligence by exploring Reactive AI, a type of AI system that responds only by following predefined rules. Students discover that Reactive AI cannot learn or adapt independently; instead, it relies entirely on rules created by people. As students test Snackbot with different snacks and develop new classification rules, they experience the role of a programmer in designing and refining an AI system. The activity reinforces key computer science concepts such as algorithms, conditionals, and rule-based decision-making while building AI literacy by demonstrating that AI systems depend on clear human instructions and carefully designed criteria to make accurate decisions.
