ab: From the text: Planning by a community includes predicting the availability
of water resources. In this modeling activity, students will find an
approximation for average rainfall and total volume of water based on
readings from rainfall gauges. Lesson outcomes include the realization
that the placement of gauges must be considered and a weighted average
utilized. In the course of the lesson, students will have an
opportunity to make a connection between the construction of the
perpendicular bisector of a line segment and finding the solution to a
real world problem.
