Although nearly everyone is familiar with colors from an early age and the fundamentals of color mixing are taught at various abstraction levels throughout kindergarten to high school, we repeatedly observe that our student teachers in physics have problems in explaining the subject. Therefore, we propose an experimental setup that focuses on the…

Arduino microcontrollers are becoming increasingly popular in the physics/astronomy community. These devices can provide more in-depth labs on mechanics, electricity and magnetism, light and optics, etc., in addition to programming. These devices can be readily utilized to reach more non-physics/astronomy majors and underrepresented STEM students.…

The Search for Exoplanets is an interactive computer simulation, the product of a collaboration between the Departments of Physics and Astronomy and Computer Science at Purdue University. Our goal was to create a computer simulation that would introduce students to scientific principles, research methodology, and analysis of data with which…

In this paper, we present activities that help students deepen their understanding of basic electrostatics using an electroscope in combination with the photoelectric effect. The students investigate the behaviour of an isolated electroscope when the metal housing of the electroscope is charged. The activities follow the framework of the…

In this paper, we present three types of activity that we have observed during students' free exploration of a software called "Algodoo," which allows students to explore a range of physics phenomena within the same digital learning environment. We discuss how, by responding to any of the three activity types we identify in the students'…

Kinesthetic experiences in the classroom seek to engage students by muscle movement, touch, or some form of physical activity. In this article, I describe an active learning session wherein students develop a qualitative understanding of center of mass and support forces using their sense of touch. The set of activities detailed here is based on a…

The dynamics of a spring pendulum is an important topic in introductory experimental physics courses at universities and advanced science courses in secondary school education. Different types of pendulum setups with smartphones were proposed to investigate, e.g., the gravitational acceleration, to measure spring constants, or to illustrate and…

Among the many decisions to be made in their teaching practice, physics teachers must decide how to explain each particular phenomenon to students. This study explores student teachers' ("STs") decision-making process when presented with several explanations of a physical phenomenon that might be used for teaching purposes. During…

In this paper, the dynamic case of a system made up of two blocks connected by a string over a smooth pulley is revisited. One mass lies on a horizontal surface without friction, and the other mass has a vertical displacement. The motion equation is obtained and its solution is determined using the "Mathematica" package. Also an…

For conducting laboratory experiments on Fresnel diffraction, the use of a simple point light source from an LED and the application of a modern smartphone for photographing the diffraction patterns are proposed. The developed devices allow the experiments to be carried out under normal laboratory lighting.

The vector of aircraft motion and analysis using FlightRadar24 and Tracker motion analysis has been investigated and studied. The straight, turning and circular aircraft motion were recorded from www.flightradar24.com using a commercial desktop video recording. Then, the video of the aircraft motion was analyzed using Tracker 5.1.1 to determine…

When injecting dye into a vortex, one finds that the dye remains captured around the vortex core over minutes, despite the fact that the vortex (and the dyed region) is strongly time-dependent. According to a recent theory, three-dimensional time-dependent vortices should be defined as rotating, material-holding regions of the fluid. Vortices…

Physics learning cannot be separated from the existence of physics measuring instruments, but their existence in schools are very limited. Therefore, creativity and innovation are needed to develop physics measuring instruments that are easily accessible by schools. This research aims to design and construct a liquid density measuring instrument…

A ball at rest on a surface can be made to bounce up by pushing it down then releasing the downward force as fast as possible. Measurements and calculations are presented to show how it can best be done.

Short videos are widely used in secondary level physics classes, part of a portfolio of strategies for teaching and learning. However, research into how they are used, why they are used and the optimum design for learning is in its infancy. This paper seeks to examine how videos are used in UK physics classrooms for the communication of physics…
