Mariur Rodriguez Moreno; Nye C. Johnson; Christopher B. Stewart; Mary L. Setelin; Adam X. Wayment; Braxton M. Felix; Scott R. Burt; David J. Michaelis – Journal of Chemical Education, 2024
We describe a three-day advanced organic laboratory experience that includes the solid-phase synthesis of an unknown three amino acid polypeptide for junior/senior undergraduate chemistry majors. Students conduct a series of 1D and 2D NMR experiments (HSQC, HMBC, TOCSY) and analyze the data to identify the side chain residues of the peptide and…

Michelle Wiebel; Kathrin Bensberg; Luca Wende; Rebecca Grandrath; Kathrin Plitzko; Claudia Bohrmann-Linde; Stefan F. Kirsch; Nils Helge Schebb – Journal of Chemical Education, 2024
Triterpenic acids (TA), a class of triterpenoids, are widely distributed as secondary metabolites in plants. They have a pentacyclic structure and show high structural diversity. In this work, a simple but efficient method for extraction and detection of TA derivatives from apple peels is described. The method is technically straightforward and…

Karen Ho; Yen Luong; Carl Sherwood; Douglas B. Clark – Chemistry Education Research and Practice, 2024
Many students find introductory general chemistry courses difficult because they feel alienated by traditional approaches to teaching and learning. This can become particularly problematic in laboratory sessions where students simply follow processes and procedures that students can view as being mundane and lacking creativity. Contextualised…

Roberts, Andrea; O'Neil, Alison L.; Barlow, Rachael; Keeler, Camille; Nelligan, William S.; Westmoreland, T. David – Journal of Chemical Education, 2021
Developing a broadly based positive culture of safety in undergraduate instructional laboratory settings remains a significant challenge for chemical educators. An enhanced safety component has been developed for an upper-level laboratory course based on earning a Chemical Hygiene and Safety badge. The badge requires student engagement in…

Johnson, Shanina Sanders; Winfield, Leyte; Sung, Shannon H. – Journal of Chemical Education, 2021
The dehydration of 2- or 4-methylcyclohexanol to obtain isomers of methylcyclohexene is a classic organic chemistry experiment. Students perform a distillation, collecting samples to analyze the progress of the reaction. The reaction produces a major product that can be explained on the basis of the regiochemistry of the [pi] bond formation for…

Roy, Brandon G.; Ryndock, Eric; Lappas, Courtney M. – Biochemistry and Molecular Biology Education, 2021
The amplification of nucleic acids is a fundamental tool utilized in various scientific disciplines, including Molecular Biology, Immunology, Microbiology, and Genetics. However, due to the time and technology required for traditional polymerase chain reaction and its derivatives, it is not always possible to include such methodologies in…

Papadimitropoulos, N.; Dalacosta, K.; Pavlatou, E. A. – Journal of Science Education and Technology, 2021
A study with K-9 Greek students was conducted in order to evaluate how the declarative knowledge acquisition was affected by incorporating Arduino experiments in secondary Chemistry Education. A Digital Application (DA) that blends the use of the Arduino sensors' experiments with digital educational material, including Virtual Labs (VLs), was…

Gallitto, Aurelio Agliolo; Battaglia, Onofrio Rosario; Fazio, Claudio – Physics Education, 2021
We describe an educational activity that can be done by using smartphones to collect data in physics experiments aimed to measure the oscillating period of a spring-mass system and the elastic constant of the helicoidal spring by the dynamic method. Results for the oscillating period and for the elastic constant of the spring agree very well with…

Gössling, Alexander; Becker, Sebastian; Kuhn, Jochen – Physics Teacher, 2021
Supersonic free-fall jumps are excellent examples of kinematics in the context of drag. They have attracted a lot of media, public, and scientific interest. In 2012, Felix Baumgartner jumped from a height of approximately 38.969 km. During his flight he reached a top speed of 373 m/s, becoming the first human to travel faster than the speed of…

Bubis, José – Biochemistry and Molecular Biology Education, 2021
Protein molecular weight standards are routinely employed in sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) to estimate the apparent sizes of unknown proteins within a sample. For training students, a laboratory course based on the production of marker proteins is proposed. Following fractionation by column chromatography, a…

McCaughey, Michael Paul; Henderson, Madison – Physics Teacher, 2021
Photogates play an important part of many of today's physics laboratory experiments. They signal when an infrared (IR) beam is interrupted, thus supplying the experimenter with important timing information. Currently photogates use an infrared photodiode (IR transmitter) and a phototransistor (IR receiver). User-built photogates have a weakness…

Dean, Jacob; Rieland, Julie M.; Love, Brian J. – Journal of Chemical Education, 2021
Fiber materials and textiles are topics of much research and study today, with efforts being made to produce fibers that are stronger, more durable, more breathable, and better for the environment. However, the production of fibers at the laboratory scale is uncommon and difficult past the prototype phase, and to a commercial fiber production…
