A. M. Ranjika P. Bopegedera – Journal of Chemical Education, 2023
Calorimetry is a central concept in the first semester general chemistry curriculum, and constant pressure (coffee-cup) calorimetry is a common experiment in the laboratory. However, constant volume (bomb) calorimetry is traditionally reserved for the physical chemistry laboratory. This article describes the advantages of incorporating bomb…

Joseph W. Shane; Lauren E. Shearer; John N. Richardson; Jeb S. Kegerreis – Journal of Chemical Education, 2023
Kombucha, a popular probiotic beverage, contains detectable concentrations of ethyl alcohol. To be sold as a nonalcoholic product, alcohol concentrations in kombucha must be shown to be less than 0.5% by volume. This paper describes the use of an inexpensive, commercially available sensor to reliably and accurately measure alcohol concentrations…

Sangeeta Nischal; Maria Zulema Cabail; Kinning Poon – Journal of Biological Education, 2024
Due to the COVID-19 pandemic and the stay-at-home order implemented by the New York State Governor, the introductory undergraduate biology courses were changed to an at-home remote learning modality. To provide conceptual learning and hands-on experience, the second semester introductory biology laboratory course utilised a multi-modal learning…

Gómez Siurana, Amparo; Font-Escamilla, Alicia – Chemical Engineering Education, 2021
In this work, different alternatives for locating the optimal feed stage in a distillation column as well as the effect of the feed temperature are studied, by solving a classroom problem. The results obtained permit us to select the best way to optimize the feed stage location as well as to detect what thermal feed phase conditions should be…

Lahane, Rohan D.; Bhatt, Harsh R.; Paranjpye, Arvind – Physics Education, 2022
Students are introduced to the term wavelength in optics at school level. In this paper, we present an inexpensive and simple method to measure the wavelength of the light of a light emitting diode using a light depending resistor. This experimental set-up is developed at Science Laboratory, Nehru Planetarium (Mumbai), India. It is useful as an…

Coelho, Ricardo Lopes – Physics Education, 2022
The pendulum was an important scientific instrument in the 17th century. It became a typical textbook problem in the 18th century. After the introduction of vectors in physics in the 1890s, the pendulum problem started to be progressively solved in the manner we know nowadays from introductory mechanics courses. Starting from "F = ma"…

Theilmann, Florian – Physics Education, 2022
Ever since Newton's groundbreaking work on the composed nature of light, additive colour mixing (and its laws) are subject to the interest of physicists as well as other sciences. In this paper, we present a setup for simple lab or home experiments on additive colour mixing and the laws of colour mixing. Students use the screen of a laptop or…

Shannon L. W. Accettone; Cassandra DeFrancesco; Lori Van Belle; Joel Smith; Erin Giroux – Journal of Chemical Education, 2022
The ability of students to perform quantitative analysis is a fundamental aspect of analytical chemistry courses and laboratories. In this laboratory experiment, students quantitatively analyze both liquid and solid samples through the use of internal standard calibration and ATR-FTIR spectroscopy. Using a problem-based approach to selecting their…

Arnold, Julia C.; Mühling, Andreas; Kremer, Kerstin – Research in Science & Technological Education, 2023
Background: Scientific thinking is an essential learning goal of science education and it can be fostered by inquiry learning. One important prerequisite for scientific thinking is procedural understanding. Procedural understanding is the knowledge about specific steps in scientific inquiry (e.g. formulating hypotheses, measuring dependent and…

Özalp, Dilek – Journal of Educational Research and Practice, 2023
Science textbooks play an important role in making scientific knowledge and applications available to learners. In most countries, science curriculum expects to cultivate scientifically literate individuals who are able to use science process skills. Critical analysis of textbooks is therefore crucial to determine whether they can facilitate this…

Gerard G. Dumancas; Noemi Carreto; Oliver Generalao; Guoyi Ke; Ghalib Bello; Arnold Lubguban; Roberto Malaluan – Journal of Chemical Education, 2023
Chemometric techniques such as partial least-squares (PLS) regression have been applied with huge success to a wide array of chemical problems including multicomponent analysis of analytes in complex mixtures. Despite this, there are few examples of laboratory pedagogical exercises that involve students in the acquisition of chemical data from…
