Supply and Demand Worksheet

Supply and demand is the concept students hear about the most and understand the least. They can recite the definition, sketch the two crossing lines on a graph, and still freeze up the moment you ask them to point to it happening in the real world. The gap usually isn't comprehension. It's application. Nobody ever sent them out to go find it for themselves.

This supply and demand worksheet fixes that by making research the assignment, not the lecture. Instead of handing students a pre-picked case study, it asks them to predict what supply and demand really means in their own words first, then brainstorm sectors of the economy that might be connected to each other through it. From there, students go looking for real evidence: news, data, anything that shows two industries moving because of the same underlying pressure. Only after they've found something real do they have to explain why the connection exists, which is the step that turns a fact students found into an idea students actually own.

That research-first structure matters for a stock market unit specifically. Students who invest through a classroom simulator will watch prices move for reasons that aren't always explained on a chart. A student who has already gone looking for supply and demand in the real world, in gas prices, in a favorite sneaker release, in whatever sector they picked, has a mental model to reach for when a stock in their portfolio jumps or drops without warning. Rapunzl has introduced more than 150,000 students to lessons like this one since 2018, and the sourcing-your-own-example approach is a big part of why it sticks.

The activity is also built for a real classroom period. Each part is short enough to move through in five to ten minutes, and the final step, sharing findings with classmates, turns five or six individual research projects into a single class discussion about how interconnected the economy actually is. There's no worksheet key to hand back and no single right answer to reveal, which keeps the conversation focused on reasoning instead of grading.

This worksheet comes from Module 1, Welcome to the Stock Market, in Rapunzl's grades 6–12 curriculum.

How Do Supply & Demand Affect The Economy?

The purpose of this activity is for students to research the concept of supply & demand, and identify (in the real world!) how this concept affects stocks of similar, and different economic sectors. With their responses, students will be able to make inferences, and connect their findings to their own personal experiences.

Part 1: What is Supply & Demand?

Make your predictions about what supply & demand really means. Be sure to refer back to your notes from today’s presentation! If permitted, share your ideas with your classmates!

Part 2: Brainstorm examples.

Brainstorm some examples of supply & demand that you can identify on your own! Can you think of any sectors of the economy that can relate to one another in terms of supply & demand?

Part 3: Find evidence of your examples… or create new ones!

Research some real-world examples of supply & demand, whether that is in the economy, or not. Find evidence, even some statistical ties between sectors that can prove these industries impacting one another!

Part 4: Identify why.

So now, you’ve found evidence linking two sectors with one another in terms of supply & demand. Now, we need to figure out why! What makes these sectors connected? Is it the customer base? The production? Explain, and predict why.

Part 5: Share with your peers!

Share what you found with your classmates, and ask any questions that you might have. Be sure to communicate with your classmates, and take note of what they found as well!

Teacher Notes

Part 1 works best when students commit to a prediction before you say anything else about supply and demand that day. If they've just sat through a presentation on the topic, resist the urge to recap it before they write. The prediction is meant to surface what actually stuck, not what they can repeat back.

Part 2 is where groups tend to gravitate toward the same two or three sectors, usually whatever's in the news that week. It's worth pushing at least one group toward a less obvious pairing so the class discussion in Part 5 has more than one example to compare.

Part 3 is the part students most often try to skip by reusing their Part 2 brainstorm as their "evidence." Ask for a source, a number, or a specific event before accepting an example as researched rather than guessed.

Part 4 is the actual reasoning step, and it's easy for students to stop at "they're both affected by the economy" without naming a mechanism. Press for a specific answer: shared customers, shared suppliers, shared raw materials, or something else concrete.
