OSAT Physics (OK114) case studies
OSAT Physics (OK114) · Put your knowledge to work in context.
OSAT Physics (OK114), also listed as CEOE Physics 114, is a subject-area certification assessment used in Oklahoma's teacher-credentialing pathway for candidates who want to teach physics at the secondary level. It is intended for people preparing to demonstrate physics content knowledge to a state-approved educator preparation program or certification authority, not for students seeking a general science endorsement. The test spans foundational scientific inquiry, mechanics and motion, energy/work/momentum, thermodynamics and kinetic theory, waves/sound/optics, electricity and magnetism, modern and atomic/nuclear physics, and laboratory safety, measurement, and data analysis. Expect conceptual reasoning alongside quantitative problem solving: interpreting graphs, selecting the right relationship, estimating, and explaining laboratory design choices. The OSAT Physics (OK114) case studies are 5 cases and about 2,984 words.
1Incline Data That Do Not Give g
A physics class uses a 1.20 m aluminum dynamics track, a 0.250 kg cart with low-friction wheels, and a motion sensor at the top of the incline. Students set the track at angles from 5° to 25° and release the cart from rest.

A student heats a 52.3 g unknown metal sample in boiling water at 98.5 °C, then transfers it quickly to a coffee-cup calorimeter containing 100.0 g of water at 22.4 °C. The mixture reaches 26.1 °C.

A group uses a helium-neon laser (λ = 632.8 nm) and a double-slit slide labeled d = 0.250 mm. The screen is 2.00 m from the slits.

Students are given a nominally 1.5 V D-cell, a small incandescent bulb labeled 1.5 V, 0.30 A, an ammeter, and a voltmeter. With the battery disconnected, a high-impedance voltmeter reads 1.58 V.
563 words, about 3 min5Density Data, Air Bubbles, and an Unknown Solid
Students receive an unknown metallic solid, a 100 mL graduated cylinder with 2 mL graduations, a balance reading to 0.01 g, and water. They are told to identify the metal from its density.
