What economic concept can students learn from a project involving buying and selling pencils?

In a project involving buying and selling pencils, students can learn about the concept of supply and demand, which is fundamental to understanding how markets operate. Supply refers to the quantity of a good that producers are willing to sell at various prices, while demand refers to the quantity of a good that consumers are willing to purchase at those prices.

As students engage in this project, they can observe how the price of pencils fluctuates based on how many pencils are available (supply) and how many pencils their peers want to buy (demand). For example, if there are a lot of pencils available but not many buyers, the price may need to decrease to encourage sales. Conversely, if pencils are in high demand but there are only a few available, the price may increase. This direct experience helps them grasp how supply and demand influence pricing and market dynamics.

Other economic concepts such as market equilibrium, price elasticity, or opportunity cost may also be relevant in different contexts, but the essential learning moment in this pencil project is centered around understanding the basics of supply and demand, making it the most fitting choice for what students can learn from participating in such a project.
