Dai, Rucheng; Wang, Zhongping; Zhang, Zengming; Sun, Lazhen – Physics Teacher, 2022
In this paper, an experimental setup composed of a color-mixing device, power supply, and spectrometer is developed. This setup is available for students to do hands-on color mixing with red, green, and blue light in undergraduate labs. LED volt-ampere and spectrum characteristics are investigated. The apparatus was used to perform additive color…

Chattopadhyay, Tanay – Science Activities: Projects and Curriculum Ideas in STEM Classrooms, 2022
In this article, simple models of optical computing circuits (1 x 4 demultiplexer (DEMUX), 4 x 1 multiplexer (MUX), Boolean logic, and half-adder (HA)) are shown with mechanically controlled plane mirrors. Photographs of the proposed computational circuits are also shown. It is very useful for the school student to understand optical logic and…

Kamphorst, Floor; Vollebregt, M. J.; Savelsbergh, E. R.; van Joolingen, W. R. – Science & Education, 2023
Einstein's derivation of special relativity theory (SRT), based on hypothetical reasoning and thought experiments, is regarded as a prime example of physics theory development. In secondary education, the introduction of SRT could provide a great opportunity for students to engage in physics theorizing, but this opportunity is largely being missed…

McGregor, Sarah L.; Pleasants, Jacob – Physics Education, 2022
Refraction is a foundational concept within introductory physics. Physics students need a deep understanding of refraction, including Snell's Law, in order to progress towards more complex optics topics such as lenses and images. Unfortunately, many physics students obtain only a superficial understanding of refraction. Although many students can…

Yurumezoglu, Kemal – Physics Education, 2020
In this article, a consecutive series of four hands-on experiments are recommended to teach the colors of paint/pigment and their mixtures. These activities, which are effective in learning about how to make a simple observation and help to build argument-based knowledge about colors, offer an integrated and innovative way of teaching colors of…

Özdemir, Erdogan; Coramik, Mustafa; Ürek, Handan – Physics Education, 2019
Optics is one of the subject areas in which students have difficulty learning. Establishing the right connections between the concepts of optics and daily life supports the learning of the concepts of optics. In addition, this connection increases the students' motivation to learn optical issues. In this study, three activities related to prisms…

Goldoni, Emanuele; Stefanini, Ledo – Physics Education, 2020
In 1919, Eddington and Dyson led two famous expeditions to measure the bending of light during a total solar eclipse. The results of this effort led to the first experimental confirmation of Einstein's General Relativity and contributed to create its unique and enduring fame. Since then, similar experiments have been carried out all around the…

Pössel, M. – Physics Education, 2020
Teaching cosmology at the undergraduate or high school level requires simplifications and analogies, and inevitably brings the teacher into contact with at least one of the pedagogical interpretations of the expanding Universe. The by far most popular interpretation holds that galaxies in an expanding Universe are stationary, while space itself…

de Carvalho, Vinícius; Martins, Victor Hugo; Fabris, Luís Victor Muller; Muller, Marcia; Fabris, José Luís – Physics Education, 2019
This work shows the production steps of two optical fibre sensing setups which were specially designed for the activities of the 2018 Photonics Lab Open Day realized at the Federal University of Technology-Paraná in Brazil as a celebration of the first International Day of Light (16 May). The systems are based on the sensing properties of fibre…

Bensky, Tom; Bensky, William – Physics Teacher, 2016
It never fails: you're in your office and the phone rings. Your department head says, "Hi! Fifty kids are coming to campus in 30 minutes. Can you meet with them and give them a one-hour hands-on activity that will make them excited about physics?" Likely you'll run to your demonstration room and grab anything that'll generate a bright…

Cengiz, Ekrem – Science Activities: Projects and Curriculum Ideas in STEM Classrooms, 2018
The goal of this study is to present and evaluate a different way of teaching concepts related to the reflection of light (incident beam, reflecting beam, angle of incidence, angle of reflection, surface, regular reflection, and diffuse reflection). The participants were 42 sixth-grade students (between the ages of 11 and 12) attending a public…

Ribaudo, Joseph – Physics Teacher, 2016
Without question, one of the most useful tools an astronomer or physicist can employ to study the universe is spectroscopy. However, for students in introductory physics or astronomy classes, spectroscopy is a relatively abstract concept that combines new physics topics such as thermal radiation, atomic physics, and the wave and particle nature of…

Kaur, Tejinder; Blair, David; Moschilla, John; Zadnik, Marjan – Physics Education, 2017
The Einstein-First project approaches the teaching of Einsteinian physics through the use of physical models and analogies. This paper presents an approach to the teaching of quantum physics which begins by emphasising the particle-nature of light through the use of toy projectiles to represent photons. This allows key concepts including the…

Bruxvoort, Crystal; Jadrich, James – Science Teacher, 2016
Science students should undertake engineering design projects and carry out scientific investigations, as recommended by the "Next Generation Science Standards" (NGSS Lead States 2013). However, studies show that students misconstrue the goals of science and engineering and are uncertain about their respective practices (Gilbert and Wade…

Planinšic, Gorazd; Etkina, Eugenia – Physics Teacher, 2015
This is the third paper in our Light-Emitting Diodes series. The series aims to create a systematic library of LED-based materials and to provide the readers with the description of experiments and pedagogical treatment that would help their students construct, test, and apply physics concepts and mathematical relations. The first paper, published…
