This teaching case highlights the complex and unique strategic issues facing social media platform companies, using Facebook as the primary, motivating example. The case centers on the breach of trust that occurred when Cambridge Analytica acquired user data from 87 million Facebook accounts and then attempted to sway the 2016 U.S. Presidential…

Using a computer and thermistor probes, students analyze graphs of temperature versus time. The experiment demonstrates phase changes in water, which can lead to a broader interpretation of matter, its properties, and the laws of thermodynamics. (Author/AIM)

Describes the building and testing of a robust pressure sensor suitable for use in schools that produces an output that can be fed into a standard computer interfacing set. (Author/NB)

Describes the application of an integrated-circuit (IC) chip which provides an easy-to-use, inexpensive, rugged, computer-interfaceable temperature sensor for calorimetry and differential temperature measurement. Discusses its design and advantages. (JRH)

Describes the use of magnetic field probes interfaced to a microcomputer in measuring the magnetic field in and around a solenoidal "Slinky" spring toy carrying a current of a few amps. (JRH)

Describes a simple, inexpensive system that allows students to have hands-on contact with simple experiments involving forces generated by induced currents. Discusses the use of a dynamic force sensor in making quantitative measurements of the forces generated. (JRH)

Presents a simple but effective experiment that uses ultrasonic transducers and some basic electronics to study the speed of sound using the Doppler effect. Eliminates the noise problems associated with most sound experiments. Discusses the theory, and describes the apparatus and procedure. (JRH)

Describes a teaching method using computer probeware to enhance students' laboratory experiences. Discusses the role of computer probeware in the science classroom, how probeware affects learning, and how it affects efficiency. (KHR)

Presents experiments that avoid using mercury by using pressure transducers to investigate the gas laws. (Author/JRH)

Describes hardware that enables the use of an IBM PC microcomputer as a frequency meter or a counter by using the parallel printer port. Eliminates the 16-bit time-day counter through the use of an external time base that can be conveniently set depending on the desired frequency range. (JRH)

Describes a measurement system for recording the frequency response of acoustic systems. The computer interface detects the characteristic modes, their relative strengths, and resonant shapes over a broad range of frequencies. Includes experimental data for tubes and analyzes the data to determine the optimal functional form for the resonant…

Presents three motion experiments that use magnetic switches for marking position and time involving an inclined plane, an air track, and sprinting. (JRH)
