Published on 01/14/2014

Activity Overview

In this lesson, students will collect data using a light sensor and analyze the effect of soil run-off on the turbidity of water.

Objectives

  • Make a model that demonstrates storm water run-off.
  • Analyze the relationship between local water turbidity and storm water run-off.

Vocabulary

  • exponential function
  • light intensity
  • particle
  • run-off
  • soil
  • turbidity

About the Lesson

In this data collection lesson, students will use a light sensor to analyze the effect of soil run-off on the turbidity of water.

 As a result, students will…

  • Measure the light intensity through a container of water with various amounts of soil in it.
  • Analyze the exponential relationship between storm water run-off and water turbidity.
