Quadratic Equations with the CBL 2

Published on 03/23/2005

Activity Overview

Students will generate parabolas using the motion sensor.
They will then determine the vertex form of the equation and compare it to the regression equation from the calculator.

Before the Activity

Set up the CBL 2™ and the motion sensor.
Plug the motion detector into the DIG/SSONIC port of the CBL 2, use the unit to unit cable to connect the calculator to the CBL 2.
Turn on the calculator and start the datamate software. Press clear to reset the data.
Zero the motion sensor so that the detector’s origin will be the floor by selecting setup from the main screen then select zero from the setup screen the select dig-distance from the select channel screen.
Then press enter to zero the sensor.

During the Activity

Please see attached Word .doc for more details for this activity.

After the Activity

Review student results:

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
