We present our experience with transferring a four-day photometry and dye-adsorption laboratory experiment to the kitchens of students of Applied Thermodynamics from our degree in "Industrial Chemical Process Engineering". The students designed and built a double-beam photometer using their smartphones and household materials, then…

An organic solar cell fabrication kit has been developed for demonstration in both undergraduate teaching classes and high school laboratories to promote the growing field of renewable energy and to facilitate empirical comprehension of solar technology. The laboratory focuses on fabricating organic photovoltaics (solar cells) and testing the…

In 2013 and 2014, over 50% (728 out of 1336 and 778 out of 1491) of candidates enrolled in constituency development fund (CDF) built secondary schools in Rachuonyo South sub-County got E to D grades which are below the acceptable minimum quality grade of C+ that enables candidates pursue competitive courses at tertiary and university levels. It is…

The commercialization of virtual reality (VR) hardware has enabled the use of VR as an educational tool. We describe how a VR platform was used to create molecular visualizations using standard PDB files with the purpose of delivering biochemistry and cellular biology lessons for undergraduates. Specifically, we describe two new software modules,…

The purpose of the current study is to design and develop a sample Mobile Augmented Reality (MAR) application addressing the anatomic structure of the heart in a way suitable for laboratory learning for pre-service science teachers to achieve learning by constructing information in biology instruction. The implementation of the MAR design activity…

Harmful plastic debris found on beaches and in the oceans are not limited to drinking straws or bags. There are several synthetic organic polymers that can be used to make different kinds of plastic materials and have resulted in billions of tons of waste that can reach the aquatic biome and are harmful to freshwater and marine communities as well…

A semester-long research project for second-semester organic chemistry lab sections was developed. Student projects were based on preliminary data from faculty research that suggested the natural product neurolenin B to be a treatment for lymphatic filariasis. Students isolated neurolenins from the Central American plant "Neurolaena…

Previous work at Monash University has shown that students recognise that inquiry-, problem-, context- and industry-based experiments were better contextualised, more open to decision making and aided in the development of scientific and transferable skills. This study investigated whether these gains persisted over a longer time scale, rather…

Techniques are needed to train students in "writing to learn", whose main goal is to "learn to write". This work aims to exemplify how writing can be a teaching learning technique in an example in Chemistry to develop a correct understanding of the preparation of molar solutions in the laboratory. It is essential that this is…

An undergraduate teaching laboratory experiment involving a continuous flow, bleach-mediated oxidation of aldehydes under biphasic conditions was developed that allowed students to explore concepts of mixing or mass transport, solvent sustainability, biphasic reactions, phase transfer catalysis, and continuous flow chemistry.

[superscript 31]P{[superscript 1]H} nuclear magnetic resonance spectroscopy is a particularly useful tool for studying the reactions of P-donor ligands such as phosphines and phosphites with transition metals and other Lewis bases because the reactions take place on the nonbonding pair of electrons on the phosphorus. In addition, [superscript 31]P…

This study aims to review the implementation of a project-based laboratory in a natural product chemistry course in order to isolate secondary metabolites from medicinal plants. Various studies on the isolation and structure elucidation of secondary metabolites can be used in natural products laboratory project. Students are directed to study…

A procedure for the study of structural differences and intermolecular attraction between ethanol and 1-butanol based in laboratory work is described. This study provides comparisons of data retrieved from both a determination of boiling point and gas chromatography traces for the mixture. The methodology reported here should provide instructors…

In this article, we describe how to develop an inductive metal detector that can be integrated to any Android or iOS smartphone with a standard audio port at low cost. The results indicate the metal detector can be used in the physics teaching laboratory as a practical application of principles of electromagnetism. It allows one to differentiate…

A set of biochemistry experiments based on the technique of protein colorimetry is described. Students used the Biuret and Bradford assays to qualitatively and quantitatively assess solutions for protein. Two unique features of these experiments are (1) the use of intentional discrepancies within each experiment to promote critical thinking and…
