Activity Overview
In this activity, students will investigate modeling the motion of two people to find where they will meet and at what rate each was walking.
Before the Activity
Connect the one calculator to one CBR 2™ unit
Download the TI Connect™ software to analyze data on the computer
See the attached PDF file for detailed instructions for this activity
Print pages 27 - 32 from the attached PDF file for your class
During the Activity
Distribute the pages to your class.
Follow the Activity procedures:
Run the Ranger program
Collect data as two people walk toward each other and away from a wall
Observe the distance versus time graphs
Determine the slope and y-intercept for each line
Use the sign of the slope to identify the direction of motion
Find the velocity for each walker
Enter the two equations in the slope-intercept form in the calculator and graph them
Determine the point of intersection of the two lines
After the Activity
Students will complete the Data Collection table and answer questions listed in it.
Review student results:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
