Forensics with TI-Nspire™ - Case File: Bouncing Back

Activity Overview

In this activity, students will be using the motion sensor as a sonar detector, through air to locate and identify a missing object in a box.

Objectives

Explore the use of ground-penetrating radar (GPR) to find buried materials.
Detect the presence of an object using a motion detector.
Distinguish between different-shaped objects using a motion detector.

About the Lesson

In this data gathering activity, students will use a motion detector to determine the presence and height of an unseen object.
Students will collect data using a CBR 2™.
The student activity sheet and .tns file contain the complete instructions for data collection. All assessment questions are also included in both places giving you the flexibility to either collect the .tns files with student data/answers (using TI-Nspire Navigator) or the student activity sheet.
