Grade Level: High School (9th-12th grade)

Objective: - Students will understand the concept of demand and its role in the economy. - Students will be able to differentiate between demand and quantity demanded. - Students will analyze factors that influence demand and their impact on the market. - Students will apply their knowledge of demand to real-world scenarios.

Materials: - Whiteboard or blackboard - Markers or chalk - Handouts with demand curve graphs - Real-world examples of products or services

Procedure:

1. Introduction (10 minutes): a. Begin the lesson by asking students if they have ever experienced a situation where they wanted to buy something but couldn’t find it in the market. b. Discuss their responses and explain that this situation is related to the concept of demand. c. Introduce the definition of demand as the desire, willingness, and ability to purchase a product or service.

2. Demand vs. Quantity Demanded (15 minutes): a. Write the definitions of demand and quantity demanded on the board. b. Explain that demand refers to the entire relationship between price and quantity, while quantity demanded refers to a specific quantity at a given price. c. Provide examples to help students understand the difference between the two concepts.

3. Factors Influencing Demand (20 minutes): a. Introduce the factors that influence demand: price, income, tastes and preferences, price of related goods, and expectations. b. Discuss each factor in detail, providing examples and encouraging students to share their own experiences. c. Use demand curve graphs to illustrate how changes in these factors shift the demand curve.

4. Analyzing Demand (15 minutes): a. Divide students into small groups and provide them with real-world examples of products or services. b. Instruct each group to analyze the factors that would influence the demand for their assigned product or service. c. Have each group present their analysis to the class, discussing the impact of each factor on the market.

5. Application and Discussion (20 minutes): a. Engage students in a class discussion about the concept of demand and its significance in the economy. b. Encourage students to apply their understanding of demand to various scenarios, such as changes in consumer income or the introduction of a substitute product. c. Facilitate a debate on the potential consequences of changes in demand for businesses, consumers, and the overall market.

6. Conclusion and Reflection (10 minutes): a. Summarize the key points discussed during the lesson. b. Ask students to reflect on how their understanding of demand can be applied to their daily lives as consumers. c. Provide an opportunity for students to ask any remaining questions or seek clarification on any concepts covered.

Assessment: - Observe students’ participation and engagement during class discussions and group activities. - Evaluate students’ understanding through their ability to differentiate between demand and quantity demanded. - Assess students’ application of the concept of demand to real-world scenarios during group presentations and class discussions.
