Oliveira, Karol N.; Naujorks, Amanda C.; Freitas, Welica P. S.; Goncalves, Alem-Mar B.; Calheiro, Lisiane B. – Journal of Chemical Education, 2021
The use of radioactive isotopes in radioactive decay studies can be a problem due to the manipulation of radioisotopes, expensive equipment, and the difficulty of finding samples with a reasonable half-life (between 1 and 10 min). In this paper, we present a mock-up of a Geiger-Mu¨ller counter plus three fictitious radioisotopes. They form an…

Pratidhina, Elisabeth; Rosana, Dadan; Kuswanto, Heru; Dwandaru, Wipsar Sunu Brams – Physics Education, 2021
Distance learning in physics is still facing challenges, mainly due to the difficult access to a laboratory for practical work. Practical work is an essential part of the physics classroom because it allows students to interact with authentic physics phenomena and develop their scientific abilities. In this paper, we propose alternative…

Idit Adler; Christopher Karam – Journal of Research in Science Teaching, 2024
Students often perceive school science as purely theoretical, overloaded with facts, and mostly disconnected from their school, home, and community life. One way to bridge the disconnection between school science and lived experiences, and support students in realizing the relevance of science to their everyday life, is by enabling them to…

Manninen, Marianna; Vesterinen, Veli-Matti; Salminen, Juha-Pekka – Journal of Chemical Education, 2020
The autumnal leaf color change is a familiar phenomenon to most students living in temperate climate zones. The extraction and analysis of the pigments of the autumn leaves provide an engaging way to study the phenomenon utilizing both simple as well as more sophisticated analytical methods. In this laboratory experiment, students extract the red…

Christianson, Anna M.; Waters, Carolyn A. – Journal of Chemical Education, 2022
We describe a guided-inquiry laboratory experiment for instrumental analysis in which our students test an improved protocol for the recycling of silver chloride to produce nontoxic waste. Students are provided with samples of silver chloride that they created as waste products in a previous lab experiment and tasked with performing a stepwise…

Phayphung, Wissarut; Rakkapao, Suttida; Prasitpong, Singha – Physics Education, 2022
The article introduces a low-cost Arduino sensor into the Young's modulus determination laboratory for physics university students. A stainless steel ruler is used as a cantilever beam. Its free end attached a mass is slightly bent and released to make it oscillate as a simple harmonic motion. The Arduino sensor detects the moving mass's frequency…
