In this math lesson, learners 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, learners graph and write an equation for a line of best fit. Learners 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.
