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.
