Forensics Case 5 - The Ink Is Still Wet: Using colorimetry to identify an unknown ink
In this activity, students identify the ink of a ransom note to match suspects. They identify an unknown ink by its light absorbance characteristics. The experiment set up used is to measure a solutions absorbance of different colors (wavelengths) of light.https://education.ti.com/en/activity/detail/forensics-case-5--the-ink-is-still-wet-using-colorimetry-to-identify-an-unknown-ink
Forensics Case 3 - Name That Tune: Matching musical tones through waveform analysis
In this activity, students analyze sound waves to calculate the frequency or pitch of musical notes. They use a Microphone to detect the waveform of a musical note. Students calculate the frequency of a musical note from the period of its waveform and use this knowledge to identify the musical n...https://education.ti.com/en/activity/detail/forensics-case-3--name-that-tune-matching-musical-tones-through-waveform-analysis
Forensics Case 12 - Hit and Run: Using information from an event data recorder to reconstruct an ac
Students learn how distance traveled, velocity, and acceleration are related to one another and how the appearance of an acceleration, velocity, or distance vs. time graph can be used to predict the appearance of the other graphs. They show how accident scenes can be recreated through an analysis...https://education.ti.com/en/activity/detail/forensics-case-12--hit-and-run-using-information-from-an-event-data-recorder-to-reconstruct-an-ac
TI-89 Riemann Sum Activities for Calculus
In this Computer Algebra System (CAS) activity students use Riemann sums to estimate the distance traveled on a trip at various speeds. They utilize the concept of Riemann sums to calculate the area under a curve. Students find limits of Riemann sums, and also convert Riemann sum limits to defini...https://education.ti.com/en/activity/detail/ti89-riemann-sum-activities-for-calculus
