JASON: Potential and Kinetic Energy--A River Study

Published on 06/09/2008

Activity Overview

Disappearing Wetlands: Simulate sediment reintroduction channels using a ramp at two slopes. They will then find the kinetic energy of the ball at different times as it rolls down the ramp.

Before the Activity

See the attached teacher document (pdf file) for notes and guidelines for this activity. The Using DataMate file (pdf file) includes step-by-step instructions on using the DataMate App.

Print and copy the attached activity document and research article (pdf files) for your class. The research article is in the During the Activity section below.

During the Activity

Students will:

  • Simulate sediment reintroduction channels using a ramp at two slopes
  • Roll a ball, which represents water, down the ramp and measure its velocity using a motion sensor connected to a TI CBL 2™ or Vernier LabPro and a TI-73 Explorer™
  • Find the kinetic energy of the ball at different times as it rolls down the ramp


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

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