How to Use This Chapter

This chapter is unlike the previous two. This is not information to absorb; it is exercises to complete. You will see specific prompts to copy, paste into your AI tool, and execute. You will observe the results. You will try variations and see how outputs change. You will document what you notice. This is active learning, and it is how you build intuition.

Here is the workflow for each exercise:

  1. Read the exercise description and understand what you are testing.
  2. Open your chosen AI tool (ChatGPT, Claude, Copilot, or Gemini).
  3. Copy the prompt exactly as written and paste it into the AI tool.
  4. Review the AI's response. How good is it? What are its strengths? Its weaknesses?
  5. Document your observations in a notebook (digital or physical).
  6. Try a variation or follow-up prompt suggested in the exercise.
  7. Compare results. What changed? Why?

Time recommendation: Spend 40-50 minutes on these exercises. Do not rush. The value is not in completing them quickly; it is in noticing details and building intuition.

Exercise 1: Professional Email Drafting

Objective

Discover how well AI handles professional communication and what tone adjustments are possible.

The Prompt

I need to send an email to a client who has been waiting a long time for their project to be completed. The delay was due to unexpected technical challenges on our end. I want to apologize, explain briefly what happened, and give them a realistic timeline for completion. The tone should be professional but warm. Write the email for me.

What to Observe

  • Does the email feel appropriately apologetic without being obsequious?
  • Does it explain the issue clearly without making excuses?
  • Is the tone professional yet warm?
  • Does it include all necessary information (acknowledgment, explanation, timeline)?
  • Would you actually send this, or does it need editing?

Variation to Try

Copy and paste the original AI response back into the chat, then send this follow-up:

Can you rewrite it to be more casual and less corporate? I want it to feel like it is coming from a real person, not a PR department.

Compare: How does the casual version differ from the original? Is it better? What did the AI change, and what stayed the same?

Exercise 2: Document Summarization

Objective

Test AI's ability to extract key information and condense lengthy content accurately.

The Prompt

For this exercise, you will need to provide a document. Use any of these options:

  • Option A: Take a recent article from a news source. Copy the full text and paste it into the AI.
  • Option B: Use this sample text (expand below):

Renewable energy adoption has accelerated dramatically over the past decade. Solar photovoltaic costs have dropped by 90% since 2010, making solar competitive with fossil fuels in most markets. Wind energy capacity has more than doubled globally. Electric vehicle sales have grown exponentially, particularly in Europe and China. Battery technology has improved substantially, with new solid-state batteries offering higher energy density and faster charging times. Grid modernization efforts are underway in most developed nations, creating smart grids that can balance intermittent renewable sources more effectively. However, significant challenges remain. Energy storage at scale remains expensive and technically difficult. Grid infrastructure in many regions is outdated and insufficient for distributed generation. Supply chains for critical minerals (lithium, cobalt, rare earths) are concentrated in a few countries, creating geopolitical risks. Public acceptance of renewable infrastructure, particularly wind farms, remains mixed in some regions. Transmission infrastructure from renewable-rich regions to population centers is often inadequate. Despite these challenges, projections suggest renewables will comprise 50% of global electricity generation by 2050, up from 30% today.

Your Task

Please summarize this document in 2-3 sentences, capturing the main point and most important details.

What to Observe

  • Does the summary accurately capture the main points?
  • Are important details included or excluded? Should they be?
  • Does the summary feel balanced (both progress and challenges)?
  • Could a non-expert understand this summary? Is it accessible?
  • Is there information in the summary that is not in the original? (This would be an error.)

Variation to Try

Now create a bullet-point summary instead—five key points I should remember from this document.

Compare: Is the bullet-point version better or worse than the paragraph summary? Why? Which format is more useful to you?

Exercise 3: Data Analysis and Pattern Recognition

Objective

Test AI's ability to analyze structured data, identify patterns, and make observations.

The Data

Here is sample sales data for a small business:

Month, Product A Sales, Product B Sales, Product C Sales, Marketing Spend
Jan, 45000, 32000, 18000, 5000
Feb, 48000, 35000, 20000, 6000
Mar, 52000, 38000, 25000, 7000
Apr, 51000, 40000, 28000, 8000
May, 54000, 42000, 30000, 8000
Jun, 56000, 45000, 32000, 9000
Jul, 55000, 44000, 31000, 7500
Aug, 58000, 47000, 35000, 9500
Sep, 60000, 49000, 37000, 10000
Oct, 62000, 51000, 39000, 10000

Your Task

Here is 10 months of sales data for our company. Please analyze the trends and tell me: (1) Which products are growing fastest? (2) Is there a relationship between marketing spend and sales growth? (3) What patterns do you see? (4) What recommendations would you make going forward?

What to Observe

  • Does the AI correctly identify trends (all products growing)?
  • Does it recognize that Product C has the highest growth rate?
  • Does it notice that marketing spend correlates with sales growth?
  • Are the recommendations reasonable and grounded in the data?
  • Does the AI acknowledge limitations or caveats (e.g., small sample size)?
  • Are there patterns the AI missed that you notice?

Variation to Try

What would happen to sales if we doubled marketing spend? Can you project sales for November and December based on current trends?

Compare: How confident are you in the projections? Are they reasonable extrapolations from the data, or are they speculative? This is a good test of AI's ability to distinguish between data-based and speculative analysis.

Exercise 4: Creative Brainstorming

Objective

Test AI's ability to generate creative ideas and explore new possibilities.

The Prompt

I run a local coffee shop in a medium-sized city. I want to increase foot traffic and build community. What are 10 creative ideas I could try? They should be realistic (not requiring huge budgets) but memorable. I want to attract both regular customers and new people.

What to Observe

  • Are the ideas genuinely creative, or just generic suggestions?
  • Are they realistic for a small business, or are they pie-in-the-sky?
  • Do any ideas surprise you—things you would not have thought of?
  • Are any ideas clearly bad or impractical? Does the AI seem to know which are better?
  • Do the ideas demonstrate understanding of your business context?

Variation to Try

Pick your favorite idea from the list and ask:

Let's develop [IDEA] further. What would be the first three steps to implement it? What could go wrong? How would I measure if it worked?

Compare: Does the AI help you think through the idea in depth, or does it stay at surface level? Does working with the AI help you refine the concept, or do you end up doing most of the thinking?

Exercise 5: Research and Information Synthesis

Objective

Test AI's ability to help with research, synthesize information, and answer complex questions.

The Prompt

I need to understand the key differences between React and Vue.js for a project decision. I have not used either before. Can you explain the main differences in a way a beginner can understand? Include: (1) learning curve, (2) community and ecosystem, (3) performance, (4) job market demand, (5) use cases where each excels. Keep it concise—I do not need deep technical details.

What to Observe

  • Does the AI explain technical differences in accessible language?
  • Are the comparisons balanced, or is there bias toward one option?
  • Does the information feel current, or outdated?
  • Are the recommendations clear, or does the AI hedge too much?
  • Does the answer help you make a decision, or does it add confusion?

Variation to Try

I have already decided to go with React. What are the best resources to learn it quickly if I am an experienced JavaScript developer? Books, courses, tutorials—what do you recommend?

Compare: Does the AI provide genuinely useful recommendations, or are they generic? How current are the resource suggestions? Does the AI acknowledge that its knowledge might be outdated?

Documenting Your Observations

As you complete these exercises, keep notes in a simple format. You can use the template below, or create your own. The goal is to capture patterns and insights so you can reference them later.

Exercise Template:
  • Tool used: ChatGPT / Claude / Copilot / Gemini
  • Task: [Brief description]
  • What worked well: [What did the AI do particularly well?]
  • What was disappointing: [What did not work as well as expected?]
  • Surprises: [Anything unexpected or insightful?]
  • Would I use this tool for this task again? Yes / No / Maybe
  • Tool I would recommend for this task: ChatGPT / Claude / Copilot / Gemini / Multiple equally good

What You Should Notice

After completing these exercises, you should have observations like these:

  • AI is fast but needs review. Every AI output, from emails to analyses, should be reviewed before use. The AI got it mostly right, but refinements were necessary.
  • Different tools have different strengths. One tool excelled at email drafting; another was better at data analysis. You now know which to use when.
  • Follow-up questions matter enormously. The first response was good, but refined follow-ups dramatically improved the output.
  • Context and specificity yield better results. Vague prompts got generic answers. Specific, detailed prompts got better results.
  • AI is good at certain tasks, still developing at others. Email and summarization felt polished. Creative brainstorming was useful but sometimes generic. Data analysis was helpful but should be verified.
  • AI is a thinking partner, not a replacement. The best results came when you used AI as a starting point and then applied your own judgment.

AI Limitations to Keep in Mind

These exercises should reveal consistent limitations across all AI tools:

  • No access to real-time information. If your question required current events or recent data, the AI might not have it.
  • No verification of factual claims. AI sometimes confidently states things that are incorrect. It does not check its own facts.
  • No understanding of your specific context. The AI does not know your budget constraints, organizational culture, or historical situation unless you explicitly state it.
  • No accountability. If the AI's advice is wrong and you follow it, the responsibility is on you, not the AI.
  • Sometimes too agreeable. AI tends to be diplomatic and agreeable rather than giving you the hard truth.
  • Sometimes confidently wrong. The AI presents incorrect information in the same confident tone as correct information. You cannot tell from tone whether something is accurate.

Key Takeaway

These exercises are not about getting perfect results. They are about building intuition through direct experience. You now understand, at a practical level, what AI tools are good at, what they struggle with, when to use them, and when to be cautious. You have moved from "I have read about AI" to "I have worked with AI and understand its strengths and limitations." This practical experience is the foundation for everything you will do with AI going forward.

Beyond This Lesson

You have now completed Lesson 3. You understand how AI tools work, you have set them up, and you have worked with them directly. The next lesson (Lesson 4: AI for Work) builds on this foundation by exploring how to integrate AI into your actual job. Lesson 4 moves from learning and practicing to productivity and real-world impact.

But before you move forward, consider revisiting these exercises in a few weeks. As you become more familiar with AI tools, you will notice new things and have deeper insights. Learning is not linear; repeated exposure builds understanding over time.
