Peter Nagy; Areej Mawasi; Ed Finn; Ruth Wylie – Science & Education, 2025
In this paper, we present findings from an exploratory qualitative study that investigated how hands-on activities can help learners think of socioscientific issues more concretely. These activities borrowed themes, such as the responsibilities of creators and limits of scientific exploration from the culturally ubiquitous Frankenstein story to…

Petra Dunkel; Bence Kontra; Barnaba´s Gere; Vuong Tran; Zolta´n Kaleta – Journal of Chemical Education, 2025
A simple demonstration adaptable to classroom conditions is presented, which involves the preparation of raffle tickets using filter paper and the solution of selected fluorophores. With an appropriate dilution, the text written on the tickets is not visible to the naked eye; however, it becomes readable once put under a UV lamp. Besides being a…

Thomas S. Kuntzleman; Andrea Matti; Dajena Tomco – Journal of Chemical Education, 2024
A mixture of salt water and isopropyl alcohol is immiscible, forming two separate liquids with the organic layer on top and aqueous layer on bottom. When universal indicator is added to such a mixture, all of the indicator compounds in the universal indicator preferentially dissolve in the alcohol--except for phenolphthalein at high pH. Mixtures…

Teng Wang; Jingjing Liu – Journal of Chemical Education, 2023
A model kit consisting of magnetic rods and steel balls, which is generally sold as a desktop toy, has been utilized to construct physical models for teaching packing arrangements of metallic crystal. All four basic metallic crystal structure models are easily constructed layer by layer, and corresponding unit cells can be naturally derived from…

Meng Wang; Jingwen He; Wei Lei; Qianfu Luo; Wenjun Wu; Wei-Hong Zhu – Journal of Chemical Education, 2024
The essence of university courses lies in their scientific rigor, while the enjoyment of learning serves as a motivation. In this regard, we have developed a comprehensive experiment project by incorporating dithienylethene-based photochromic units into sensitizers for renewable energy, specifically dye-sensitized solar cells, through organic…

Courtney Devera; Cassidy Fine; Kerri L. Shelton; Rajeev B. Dabke – Journal of Chemical Education, 2025
Many simple chemical reactions produce an audible fizz due to the formation of gases, such as oxygen, hydrogen, or carbon dioxide. A hands-on activity based on perceiving these audible chemical changes is presented. The relative quality of fizz due to the formation of gases in a chemical reaction was determined by visually impaired middle and high…

Oyama, Hiroshi; Nabeshima, Yuka; Morimoto, Koichi; Sugimura, Yukio – Biochemistry and Molecular Biology Education, 2023
Coagulation is an important process in the context of water purification; and the seed protein of the moringa tree ("Moringa oleifera") is a remarkably effective coagulant. The laboratory course described here is designed to provide high-school students with a stepwise, hands-on experience in investigating the protein-rich coagulant…

Michelle Garcia; Frances A. O'Leary; Daniel J. O'Leary – Journal of Chemical Education, 2023
This report outlines an approach for preparing 5-color 3D printed plastic models of molecular orbitals and electron density surfaces using a hobby-grade 3D printer. Instructions are provided for preparing 3D orbital and electron density surface (EDS) models using solid or mesh representations in ground state and transition state structures. We…

Dorji Tenzin; Karma Utha; Kinley Seden – Research in Science & Technological Education, 2024
Background: Electric circuit concepts in physics are abstract in nature and students find it difficult to comprehend. Purpose: This study was designed to compare the impact of three different strategies: simulation, hands-on and a combined strategy in enhancing conceptual understanding on electric circuit for class X students. Design: A mixed…

Williams; Zachary Conley; Hinton Antentor Jr. – Advances in Physiology Education, 2024
Physiology is an important field for students to gain a better understanding of biological mechanisms. Yet, many students often find it difficult to learn from lectures, resulting in poor retention. Here, we utilize a learning workshop model to teach students at different levels ranging from middle school to undergraduate. We specifically designed…

Martin Schwichow; Anastasios Zoupidis – Journal of Research in Science Teaching, 2024
Floating and sinking (FS) is a key topic in science education, both at primary and secondary levels. The interpretation of FS phenomena, however, is challenging due to the difficulty of the scientific concepts and explanatory models involved (e.g., density, buoyancy), along with students' everyday experiences, which conflict with scientific…

John O'Donoghue; Natalia Garci´a Dome´nech; Fiona McArdle; Mary Connolly; Yvonne Lang; Niamh McGoldrick – Journal of Chemical Education, 2023
Over the course of the COVID-19 pandemic, school students suffered from a reduction in opportunities to connect with higher education institutions, meet scientific role models in person, discuss scientific career options, and carry out hands-on practical laboratory activities. Current Chemistry Investigators (CCI) is a successful…
