This learning resource focuses on a market simulation activity where students, acting as marketing managers in a fundraising event, analyze how price influences the quantity of water bottles bought and sold. The document outlines different price points to test, such as $5, $10, $15, and $20, and encourages students to make predictions about sales at each price. It includes a data table for recording predicted versus actual sales quantities and prompts students to brainstorm reasons for how pricing affects buyer behavior. Additionally, it describes the steps for a classroom market simulation where students engage as buyers and sellers to observe market dynamics in real-time, culminating in reflection questions that help them explore their observations and learning about market strategies and consumer behavior.
