In analytical chemistry, discussing different method sand techniques of analysis is essential to promote critical thinking and reasoning. Analytical courses in the chemist, pharmacist, and biochemist curricula represent the opportunity to study concepts such as experimental design, sampling, development, and optimization of protocols, data…

Exciting developments in the field of Green Chemistry spur the continuous innovation of experiments in the teaching laboratory. Beyond learning practical techniques, students can critically assess experiments using relevant metrics to propose further improvements and identify the most important interconnected impacts of these alternative products…

This experiment is dedicated to second-year and above undergraduates who are in their experimental session of the analytical chemistry course. Grouped students are required to use a TiO[subscript 2] photocatalytic oxidation process to treat the methanol-containing wastewater that resulted from their previous HPLC experiments. Students learn to…

It was planned to introduce online pre-laboratory session activities to a first-year undergraduate physics laboratory course to encourage a minimum level of student preparation for experiments outside the laboratory environment. A group of 16 and 17 year old laboratory work-experience students were tasked to define and design a pre-laboratory…

Recent emphasis on the science of food and cooking has been observed in our popular literature and media. As a result of this, a new non-science majors course, The Science of Food and Cooking, is being taught at our institution. We cover basic scientific concepts, which would normally be discussed in a typical introductory chemistry course, in the…

It is challenging for biomedical engineering programs to incorporate an indepth study of the systemic interdependence of cells, tissues, and organs into the rigorous mathematical curriculum that is the cornerstone of engineering education. To be sure, many biomedical engineering programs require their students to enroll in anatomy and physiology…

Describes the infrared analysis of geological specimens which can form the basis of a laboratory exercise, allowing some minerals to be identified by "fingerprint" technique. Students can gain insight into the concept of symmetry and environment around an atom. (Author/SA)

Discusses the need for student research-type chemistry projects based upon "unknown" metal complexes. Describes an experiment involving the product from the reaction between cobalt(II) chloride, ethane-1,2-diamine (en) and concentrated hydrochloric acid. Outlines the preparation of the cobalt complex, along with procedure, results and…

Describes an experiment designed to introduce biochemistry students to the specificity of an analytical method which uses an enzyme to quantitate its substrate. Includes the use of toxicity charts together with the concept of the biological half-life of a drug. (TW)

Discusses the need for student experiments involving the complete characterization of "unknown" inorganic compounds. Describes a project employing a complex metal compound. The compound contains six different components in both inert and labile complexions. Outlines the complete procedure and the preparation of the unknown compound. (TW)
