Algebraic Thinking Focus
Modeling or simulating real world situations can help students develop the idea of function. Such experiences build an understanding of variable, the relationship between variables, and generalizing these relationships.
Lesson Objective
Students will design and carry out an experiment to model a real world situation. They express their results with multiple representations and use the results to make predictions.
Overview of the Lesson
Students design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak. Using the data they gather in a table, students graph and write an equation for a line of best fit. Students then use their derived equation to make predictions about the amount of water that would be wasted from one leak over a long period of time or the amount wasted by several leaks during a specific time period.
