Introduction
Imagine why the price of gasoline suddenly increases or why gadgets become cheaper after a few months. These changes are not random—they are influenced by supply and demand, two of the most important concepts in economics. In this lesson, students will explore how these forces interact to determine prices in the market and affect everyday decisions.
Task
Students will analyze a real-life product (e.g., rice, smartphones, or clothing) and create a short presentation or infographic explaining how supply and demand affect its price.
End Product:
A visual presentation (PowerPoint, Canva, or poster) showing:
- Definition of supply and demand
- Factors affecting each
- A real-life example
- A simple supply and demand graph
Process
- Understand the Concepts
Study the basic meaning of supply and demand and how they interact. - Choose a Product
Select a common product relevant to daily life. - Research Factors
Identify factors affecting supply (e.g., cost of production) and demand (e.g., consumer preference). - Analyze the Market
Explain how these factors affect the price of your chosen product. - Create a Visual Output
Prepare a presentation or infographic with explanations and a simple graph. - Present Findings
Share your work with the class.
Resources
- Online articles on supply and demand (e.g., Investopedia, Khan Academy)
- YouTube videos explaining supply and demand
- Textbook (Economics Grade 10)
- Graphing tools (Excel, Canva, or paper)

Conclusion
In this lesson, students learned how supply and demand influence prices in real life. By analyzing real-world products, they developed a deeper understanding of economic behavior and decision-making. This activity also encouraged critical thinking, collaboration, and practical application of concepts, helping students connect economics to everyday experiences.
