Using the CBR

This resource provides educators with a structured agenda for utilizing the CBR (Calculator Based Ranger) in teaching physics concepts with the TI-73 and TI-83+ calculators. The activities include a motion detection experiment where students analyze a real-world scenario involving distance and time. Students will engage in creating graphs based on their movements and will have the opportunity to visualize their first initials using CBR data collection. This hands-on approach fosters understanding of motion concepts and promotes active participation in learning.

  1. Using the CBR Lisa M Suarez-Caraballo LisaS@copper.net http://education.ti.com

  2. Using the CBR with the TI-73/83+ Agenda APPlications on the TI-73 • Using the CBR – Motion Detector • Pre Test • Your Name’s the Game • Sample Student Responses to PreTest

  3. Pre Test Jose’s mother sent him to the store to buy some things that she needed. Half way to the store Jose realized that he had left the money sitting on the table. He turned around, went home, got the money and returned to the store where he bought the items his mother had asked for and went back home.

  4. Make a Distance vs. Time graph of Jose’s Motion. Distance Time

  5. Using the CBR

  6. Your Name’s the Game! • Using the CBL/CBR APP and moving with or in front of the CBR try to “draw” the first letter of your first name on the screen.

  7. Run the CBL/CBR APP

  8. Choose SET DEFAULTS to run CBR and follow on screen directions Select Ranger

  9. Press Enter to begin collecting data and make a graph • To try again, select 3: Repeat Sample from the Plot Menu

  10. What letters could you make? • M • N • W WHY??

  11. Student Pre Test Responses

  12. Thank You!!
