Tiano, Martin – Journal of Chemical Education, 2020
We adapted a classical asymmetric Michael addition for a 1 day experimental session (6-8 h) for third- or fourth-year undergraduate students. The experiment contains three steps: synthesis of a chiral Lewis acid, LiAl((S)-BINOL)[subscript 2], then its use as a catalyst in the Michael addition of diethyl malonate on cyclopentenone, followed by…

Baqi, Younis – Journal of Chemical Education, 2022
A fast, operationally simple, and reproducible synthetic protocol for anthraquinone dyes (AQDs), suitable for upper-division undergraduate industrial and organic chemistry laboratory courses, has been developed. This experiment is composed of three stages; the first step deals with the synthesis of AQDs, followed by a purification step, and…

Johnson, Bettie Obi; Golonka, Annette M.; Emmanuel, Khalisha A.; Ponnarasu, Jeffshan J.; Pryor, Joseph E. – Journal of Chemical Education, 2022
A novel undergraduate analytical chemistry experiment involving the identification and quantification of linalool in essential oils was developed. The experiment uses the internal standard method with headspace solid phase microextraction (SPME) and gas chromatography--mass spectrometry (GC-MS). This method is applicable to any linalool-containing…

Khalid, Habiba; Amin, Farrukh Raza; Chen, Chang – Biochemistry and Molecular Biology Education, 2022
An integrated laboratory experiment was designed for introducing biochemistry students to basic static biochemistry to deepen their understanding on the properties and analysis of biomolecules such as total carbohydrates, lipid, protein, and protein-constituent amino acids. Food represents a very important source of biomolecules of technological…

Ha, Hye Jin; Jang, Taehun; Sohn, Sang Ho – Physics Education, 2022
In this study, we derived several formulas for the currents induced in a circular loop by a magnet connected to a spring-based simple harmonic oscillation system. In addition, we conducted an experiment for measuring the induced currents and compared the results with the theoretical prediction. It was confirmed that the prediction from the derived…

Danielle L. Pearson; Russell R. A. Kitson – Journal of Chemical Education, 2022
An introductory normal phase column chromatography experiment is described and evaluated for second year undergraduate chemistry laboratory class. The experiment involves a nucleophilic substitution yielding a crude mixture of reactant and one product, both of which are brightly colored and contrasting, creating a clearly visual separation when…

Sarah Ritter; Liza Abraham – Journal of Chemical Education, 2022
This project introduces green chemistry to the undergraduate laboratory through two pedagogical techniques: undergraduate research and guided-inquiry. Through these two learning activities, an efficient synthetic procedure for the PRINS cyclization of citronellal into isopulegol, focused on minimizing negative environmental impact, was developed.…

Mark F. Mechelke – Journal of Chemical Education, 2022
A drug discovery project has been successfully implemented in an advanced undergraduate organic chemistry laboratory. In the laboratory, a five-step synthetic sequence is used to prepare five analogues of 13-phenyl-1-tridecanol. These compounds are key precursors in the synthesis of 2-oxo-14-phenyltetradecanes. This class of compounds, isolated…

Meryssa Piper; Jessica Frankle; Sophia Owens; Blake Stubbins; Lancen Tully; Katherine Ryker – Journal of Geoscience Education, 2025
Rock and mineral labs are fundamental in traditional introductory geology courses. Successful implementation of these lab activities provides students opportunities to apply content knowledge. Inquiry-based instruction may be one way to increase student success. Prior examination of published STEM labs indicates that geology labs, particularly…

Yannik Hilla; Maximilian Stefani; Elisabeth V. C. Friedrich; Wolfgang Mack – Cognitive Research: Principles and Implications, 2025
Whether or not it is possible to predict military performance using laboratory measures constitutes an important question. There are indications that humans possess a common multitasking ability enabling them to perform complex behaviors irrespective of task requirements. Working memory processing abilities likely illustrate cognitive substrates…

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…

Qi Zheng – Journal of Microbiology & Biology Education, 2024
The importance of teaching the Luria-Delbrück experiment to biology students is increasingly recognized by educators, and improved pedagogical methods for teaching the classic experiment have been proposed and tested in the classroom. However, there are still obstacles that impede the proper teaching of the classic experiment. This note proposes…
