Billingsley, Brianna R.; Christenson, Cory W. – Physics Teacher, 2022
A popular introductory physics laboratory experiment is one focusing on Snell's law. This is straightforward to complete with lasers and prisms, but here we present an alternative version that guides the students through some of the major historical developments, recreating and analyzing significant experiments. The discovery of Snell's law has a…

Polley, J. P. – Physics Teacher, 2021
While the three laws of conservation of energy, momentum, and angular momentum are all mentioned in introductory textbooks, there are few experiments through which students can investigate the conservation of angular momentum. Most experiments consist of collisions between rotating disks, in which one disk is dropped on another, or in which the…

Vandervoort, Kurt – Physics Teacher, 2020
Newton's law of cooling describes an object whose temperature decreases exponentially with time. Because of its many applications, it is a frequent topic of introductory physics labs. In this article, I describe an experiment designed for the freshman year algebra-based physics course that applies this law to answering the question, "Why…

Galeriu, Calin – Physics Teacher, 2018
The recent use of Arduino Uno microcontroller boards for automated data acquisition has revolutionized physics education. The Arduino-based physics labs have dramatically lowered the cost of the experimental equipment, while at the same time replacing the commercial apparatus with open hardware and software. Students benefit greatly from rigorous…

Lane, W. Brian – Physics Teacher, 2019
In tabletop games involving dice, it is important to ensure randomness of the dice rolls and to protect other gaming elements from being scattered by rolling dice. One way of ensuring random rolls and protecting gaming elements is to drop dice into a dice-rolling tower ("dice tower"). A dice tower is usually small (20 cm by 20 cm) and…

Liu, Dan; Duan, Zhuojan – Physics Teacher, 2021
Equilibrium is an essential concept in undergraduate physics curriculum as it integrates Newton's laws and torque. The importance also comes from its wide applications in mechanics and biomechanics. Simulations of Back and Arms are developed mainly for the undergraduates who major in physical therapy and health sciences. They are implemented as…

Kutzner, Mickey D.; Bryson, Michael – Physics Teacher, 2018
There remains a strong movement for Introductory Physics for Life Sciences (IPLS) courses to better integrate physics and biology. Part of the challenge for IPLS educators is to introduce fundamental physical law while simultaneously establishing the relevance of physics to biological science. Life science relevant laboratory experiences are…

Lincoln, Don; Stuver, Amber – Physics Teacher, 2016
In a deep and dark corner of space, a cataclysm loomed. Two cosmic nemeses circled one another, locked in a macabre dance of death. Unfolding over millennia, the deadly waltz began leisurely enough. But with the dance came radiation and the energy loss that it implies. Orbit after orbit, the distance between the two protagonists shrank as their…

Kaar, Taylor; Pollack, Linda B.; Lerner, Michael E.; Engels, Robert J. – Physics Teacher, 2017
The use of systems in many introductory courses is limited and often implicit. Modeling two or more objects as a system and tracking the center of mass of that system is usually not included. Thinking in terms of the center of mass facilitates problem solving while exposing the importance of using conservation laws. We present below three…

Saviz, Camilla M.; Shakerin, Said – Physics Teacher, 2014
Many students have owned or seen fluids toys in which two immiscible fluids within a closed container can be tilted to generate waves. These types of inexpensive and readily available toys are fun to play with, but they are also useful for provoking student learning about fluid properties or complex fluid behavior, including drop formation and…

Doran, Patrick; Hawk, William; Siegel, P. B. – Physics Teacher, 2014
Maxwell's discovery of the relation between electricity, magnetism, and light was one of the most important ones in physics. With his added displacement current term, Maxwell showed that the equations of electricity and magnetism produced a radiation solution, electromagnetic (EM) radiation, that traveled with a speed of c=1/v(e0µ0). The…

Nelson, Jim; Nelson, Jane Bray – Physics Teacher, 2015
In this paper, a discrepant event is used to initiate a learning cycle lesson to help students develop an understanding of the concept and equation for buoyant force. The data are gathered using readily available equipment and then graphically analyzed using a four-step analysis consistent with the modeling instructional approach. This laboratory…

Countryman, Colleen Lanz – Physics Teacher, 2014
"The Physics Teacher's" "iPhysicsLabs" column has been dedicated to the implementation of smartphones in instructional physics labs as data collection devices. In order to understand any data set, however, one should first understand how it is obtained. This concern regarding the inclusion of smartphones in lab activities…

Stout, Roland – Physics Teacher, 2011
After finding Moloney and McGarvey's modified adiabatic compression apparatus, I decided to insert this experiment into my physical chemistry laboratory at the last minute, replacing a problematic experiment. With insufficient time to build the apparatus, we placed a bottle between two thick textbooks and compressed it with a third textbook forced…

Kranjc, T.; Razpet, N. – Physics Teacher, 2011
Many physics textbooks start with kinematics. In the lab, students observe the motions, describe and make predictions, and get acquainted with basic kinematics quantities and their meaning. Then they can perform calculations and compare the results with experimental findings. In this paper we describe an experiment that is not often done, but is…
