JASON: Mixing Soil And Water--Let's Settle This?

Published on 06/09/2008

Activity Overview

Disappearing Wetlands: Investigate how particles settle by measuring the amount of light passing through the water as particles settle. Make connections to the process by which sediment settles out of the Mississippi River to form coastal wetlands.

Before the Activity

See the attached teacher document (pdf file) for notes and guidelines for this activity.

Print and copy the attached activity document and research article (pdf files) for your class.

Refer to Appendix A Using Datamate for instructions as needed.

During the Activity

Students will:

  • Perform an experiment to simulate sediment deposition in still water
  • Examine the settling of sediment from two different types of soil; sandy soil and potting soil
  • Investigate how sediment particles settle
  • Measure the amount of light passing through the water as particles settle using a Light Sensor
  • Make connections between the sediment settling in the experiment and the process by which sediment settles out of the Mississippi River to form coastal wetlands


  • Directions
  • Distribute the actviity document and research article to your class
  • Read and discuss the research article
  • Follow the activity procedures
  • After the Activity

  • Students complete the data analysis section of the activity.
  • Discuss the results of the data analysis with your students.
