OAE Physics (035) case studies
OAE Physics (035) · Put your knowledge to work in context.
The OAE Physics (035) is a subject-matter assessment used in Ohio's educator-licensure process for candidates who want to teach physics. It is typically taken by people completing an teacher-preparation program, by candidates adding a physics endorsement to an existing license, and by out-of-state educators seeking Ohio licensure. The OAE Physics (035) case studies are 5 cases and about 3,896 words.
1When a Student's Planck Constant Is 18% Low
A high school physics teacher is mentoring a student's independent project that estimates Planck's constant from the turn-on voltage of five LEDs. The student measured red, yellow, green, blue, and violet LEDs with a digital voltmeter, took the manufacturer's peak wavelength for each, and plotted V versus 1/λ.

Students drop a tennis ball from a measured height of 1.50 m and record the bounce with a smartphone at 240 frames per second. They track the ball's center frame by frame and compute a rebound height of 0.92 m, giving a coefficient of restitution e = √(0.92/1.50) = 0.78.

A lab group is measuring the current–voltage relationship for a small incandescent bulb and a 100 Ω carbon resistor. Using a variable DC supply, they record for the bulb: 1.5 V, 0.15 A; 3.0 V, 0.22 A; 6.0 V, 0.32 A.

A student uses a diffraction grating labelled 600 lines/mm and a red laser to measure the laser's wavelength. The grating is clamped to a lab bench, and the screen is a sheet of paper taped to a wall 1.20 m away.

Students determine the specific heat of an unknown metal by calorimetry. They heat a 50.0 g sample in boiling water at 98.0 °C, then transfer it quickly to a coffee-cup calorimeter containing 150.0 g of water at 22.0 °C.
