Forensics Case 9 - Killer Cup of Coffee: Using colorimetry to determine concentration of a poison
In this activity, students will use colorimetry to determine the concentration of a colored species in a solution and use a linear relationship to model Beer's law. They use Beer's law to determine the concentration of iron(III)thiocyanate (FeSCN2+) in an unknown solution.https://education.ti.com/en/activity/detail/forensics-case-9--killer-cup-of-coffee-using-colorimetry-to-determine-concentration-of-a-poison
Vernier - How Low Can You Go?
In this activity, students will use an EasyTemp temperature probe to determine the normal melting temperature of ice. They will then study how the addition of salt to the melting ice affects its melting temperature. They will finally formulate a procedure for reaching the coldest melting temperat...https://education.ti.com/en/activity/detail/vernier--how-low-can-you-go
Forensics Case 8 - No Dumping: Using soil characteristics to link suspects to a crime scene
In this activity, students measure pH, conductivity, and water absorbency of different samples of soil. They use these characteristic properties to identify soil samples. They use the physical and chemical characteristics of soil samples collected from suspects to determine whether a suspect had ...https://education.ti.com/en/activity/detail/forensics-case-8--no-dumping-using-soil-characteristics-to-link-suspects-to-a-crime-scene
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
Get on the Stick (Biology Applications)
Students use a motion detector to the measure the reaction time of other students. They graph the data from trials conducted in the class and analyze trends. They then calculate drop distance from reaction time.https://education.ti.com/en/activity/detail/get-on-the-stick-biology-applications
Infinite Geometric Series
Students explore infinite geometric series. They will consider the effect of the value for the common ratio and determine whether an infinite geometric series converges or diverges.https://education.ti.com/en/activity/detail/infinite-geometric-series
