Forensics Case 12
Hit and Run: Using information from an event data recorder to reconstruct an ac
 


Activity Overview

Students learn how distance traveled, velocity, and acceleration are related to one another and how the appearance of an acceleration, velocity, or distance vs. time graph can be used to predict the appearance of the other graphs. They show how accident scenes can be recreated through an analysis of the data that are gathered by an event data recorder (EDR).

Before the Activity

  • Use TI Connect™ to download Vernier EasyData™ application
  • Connect the CBR 2™ to the calculator with the unit-to unit link cable
  • See the attached PDF file for detailed instructions for this activity
  • Print pages 106 - 110 from the attached PDF file for the class
  • Print sample data and student work pages
  • Set up the calculator for data collection

    		•

    		During the Activity

    		Distribute the pages to the class.

    Follow the Activity procedures:
  • Place the CBR 2 on the floor (or table) facing the toy car
  • Push the car away from the CBR 2 and start taking the distance readings
  • Examine graphs of distance versus time and velocity versus time
  • Note the time when the car began to move
  • Record the maximum velocity of the car, time when the car attained its maximum velocity, and the distance traveled before attaining maximum velocity
  • Examine the EDR data and reconstruct the events of the accident
  • Identify if the EDR data supports the suspects stories and find the culprit

    		After the Activity

    		Students analyze the results and answer the Case analysis questions on the Evidence Record sheet.

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