Activity Overview
Students physically provide motion data that is collected by a CBL™ and then graph the data. They determine if they "moved in the right directions" by comparing their graph with those printed in the activity.
Before the Activity
Connect the motion sensor to the CBL 2through the SONIC port
Connect the CBL to the calculator using the unit-to-unit link cable
See the attached PDF file for detailed instructions for this activity
Print pages 113 - 122 from the attached PDF file for your class
During the Activity
Distribute the pages to the class.
Follow the Activity procedures:
Examine the provided distance versus time graph
Calculate the slope
Understand that the slope is actually the speed of the walker
Walk in front of the motion sensor at the pace determined from the graph
Observe the distance-time graph on the calculator
Compare the graph generated with the graph provided
Check whether the two graphs are similar
Repeat the activity with different graphs
Use the information on the graph to develop a walking strategy and record it
Start collecting data and compare calculator graphs with the ones provided
After the Activity
Students complete the Questions sheet.
Review student results:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
