Science Nspired - Forensics - Case Files by Texas Instruments

These engaging activities have students solving crimes with TI-Nspire™ technology and Vernier Software & Technology™ data collection sensors! As students explore the case files, they become student investigators- solving mysteries by collecting and analyzing data with the built-in Vernier DataQuest™ app for TI-Nspire™. These highly engaging activities will not only spark curiosity, but will challenge students to use math and science to solve real-world problems.

Forensics with TI-Nspire™ - Case File: Bouncing Back 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. Standards Textbook		Download424
Forensics with TI-Nspire™ - Case File: Name That Tune In this activity, students will analyze sound waves to calculate the frequency, or pitch, of musical notes. Standards Textbook		Download329
Forensics with TI-Nspire™ - Case File: Flipping Coins In this activity, students will explore the concept of density and use it to distinguish between pennies minted in different years. Standards Textbook		Download375
Forensics with TI-Nspire™ - Case File: The Ink is Still Wet In this activity, students will use colorimetry to identify inks as unique mixtures of pigments. Standards Textbook		Download401
Forensics with TI-Nspire™ - Case File: Drug Tests In this activity, students will attempt to identify an unknown “drug” as they explore the differences between chemical and physical properties and between qualitative and quantitative observations. Standards Textbook		Download405
Forensics with TI-Nspire™ - Case File: No Dumping In this activity, students will investigate the importance of soils and other trace evidence in connecting victims, crime scenes, and suspects. Standards Textbook		Download407
Forensics with TI-Nspire™ - Case File: A Killer Cup of Coffee In this activity, students will use colorimetry to calculate the concentration of an unknown solution by measuring how it absorbs a specific wavelength of light. Standards Textbook		Download520
Forensics with TI-Nspire™ - Case File: Dropped at the Scene This lab introduces students to the science behind blood spatter analysis. It also provides an opportunity for students to explore curve fitting and can extended to use r² values (optional) to determine the most appropriate curve fit for the data set. Standards Textbook		Download485
Forensics with TI-Nspire™ - Case File: Ashes to Ashes In this activity, students will learn that evaporation rate is a characteristic property of a liquid. Based on this fact, they will identify the solution and the likely accelerant in a case of arson. Standards Textbook		Download368
Forensics with TI-Nspire™ - Case File: Hit and Run In this activity, students will learn displacement, velocity, and acceleration are related quantities. Students will explore how patterns in one measurement can be used to predict patterns in the others. Standards Textbook		Download655
Forensics with TI-Nspire™ - Case File: Life in the Fast Lane In this activity, students will investigate the coefficient of friction and use it to determine the speed of a vehicle from the distance of its skid. Standards Textbook		Download448
Forensics with TI-Nspire™- Case File: Hot Air, Cold Body In this activity, students will use Newton’s Law of Cooling to determine the time of death at a crime scene. Standards Textbook		Download720
