GENERAL INFORMATION

Title:	Drip, Drop, Drip, Drop
Resource ID:	4681
URL:	http://www.pbs.org/teachers/mathline/lessonplans/atmp/dripdrop/dripdrop_procedure.shtm
Resource Description:	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.

Instructional Component Type(s):

Problem-Solving Task (Primary Type)

Keywords:
