Food and the Columbian Exchange
Human vs. AI Research Battle: The Significance of Foods
- Have students list foods that spread during the Columbian Exchange, then prompt AI to expand it.
- Then, have students ask AI which one food had the greatest historical impact.
- Finally, challenge students to do some of their own research to evaluate and critique the AI response.
What makes this effective? Students get to learn about historical significance using AI as a research partner. But rather than simply accepting the AI results, they use their own research to challenge or confirm its responses using evidence they gather, providing a valuable exercise in information literacy.
