Activity Overview
In this activity, students will determine the coasting distance of a toy car if it is rolled down from different fixed distances down an inclined plane.
Before the Activity
Install the CBL/CBR Application on the students' graphing calculators using TI Connect™ or TI-GRAPH LINK™, TI Connectivity cable, and the unit-to-unit link cable
Connect the TI-73 to the CBL 2 and CBR 2
See the attached PDF file for detailed instructions for this activity
Print pages 117 - 127 from the attached PDF file for your class
During the Activity
Distribute the pages to your class.
Follow the Activity procedures:
Position the CBR at the bottom of the ramp to measure the distance the car coasts after leaving the ramp
Hold and release the car 0.5 m from the starting line on the top of the ramp and record the coast distance
Repeat for all seven cars
Repeat the activity releasing the cars 1 m and then 1.5 m from the starting line
Record the data and create a bar graph
Understand the relationship between the starting point and the distance traveled
Analyze the data and identify the car with the greatest coasting distance and relate it to the car design
After the Activity
Students will fill in the Student Data Collection and Analysis Sheet and answer questions in it.
Review student results:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
