What does the CBR 2™ sonic motion detector do?
With the CBR 2™ motion detector and a TI graphing calculator, students can collect, view,
and analyze motion data without tedious measurements and manual plotting.
The
CBR 2™ motion detector lets students explore the mathematical and scientific
relationships between distance, velocity, acceleration, and time using data collected from
activities they perform. Students can explore math and science concepts such as:
0 motion: distance, velocity, acceleration
0 graphing: coordinate axes, slope, intercepts
0 functions: linear, quadratic, exponential, sinusoidal
0 calculus: derivatives, integrals
0 statistics and data analysis: data collection methods, statistical analysis
0 Physics: motion, use with dynamics tracks, pendulum analysis, position, velocity,
acceleration
0 Physical Science: motion experiments
What’s in this guide?
Getting Started with the CBR 2™ Sonic Motion Detector is designed to be a guide for
teachers who do not have extensive calculator experience. It includes quick-start instructions
for using the
CBR 2™ motion detector, hints on effective data collection, and five classroom
activities to explore basic functions and properties of motion. The activities (see pages 10–
31) include many of the following:
0 teacher notes for each activity, plus general teacher information
0 step-by-step instructions
0 a basic data collection activity appropriate for all levels
0 explorations that examine the data more closely, including what-if scenarios
0 suggestions for advanced topics appropriate for precalculus and calculus students
0 a reproducible student activity sheet with open-ended questions appropriate for a wide
range of grade levels
