Time to play! Open any free AI chatbot (ChatGPT, Grok, Gemini, or Claude) and try these experiments one by one. Write down or remember the differences in answers.

Experiment 1 – Length control Prompt A: “Tell me a joke about cats.” Prompt B: “Tell me one very short joke about cats (maximum 20 words).” → Notice how B forces a quick, punchy joke.

Experiment 2 – Tone change Prompt A: “Describe a rainy day.” Prompt B: “Describe a rainy day in a romantic way like a poet.” Prompt C: “Describe a rainy day in a scary horror story style.” → Same topic — completely different feelings!

Experiment 3 – Role play Prompt: “Act as a friendly science teacher. Explain why the sky is blue to a curious 8-year-old using easy words and one example.” → AI becomes your personal teacher!

Experiment 4 – Comparison Prompt: “Compare Grok and Gemini in 3 bullet points: strengths, weaknesses, and best use cases in 2026.” → AI gives you a quick summary to help choose your favorite tool.

Bonus challenge: Ask the same question to two different chatbots (e.g., ChatGPT and Claude). See how their personalities and answers differ slightly.

Do at least 5 experiments and notice: Small changes in your prompt = big changes in output. This is the magic of prompt engineering!
