A laboratory experiment was developed to enable students to investigate the use of smart hydrogels for potential application in targeted drug delivery. This is challenging for students to explore practically because of the extremely high risks of handling cross-linking agents such as glutaraldehyde. Genipin is a safe and green alternative that has…

In general, laboratory experiments focus on traditional chemical disciplines. While this approach allows students the ability to learn and explore fundamental concepts in a specific area, it does not always encourage students to explore interdisciplinary science. Often little transfer of knowledge from one area to another is observed, as students…

Students should enjoy their laboratory classes and for this purpose a project-based activity is added to a conventional physical chemistry laboratory. Students were given project work instead of conventional experiment and then they had to make progress in the project according to instructions and then carry out experiments related to the project.

Describes the synthesis of a sweetening compound that requires seven laboratory periods of three-hours duration. (MLH)

A scanning tunneling microscope (STM) project designed as a module for the undergraduate physical chemistry laboratory is described. The effects of van der Waals interactions on the condensed-phase structure are examined by the analysis of the pattern of the monolayer structures.

Describes a chemistry project in which lichens are identified by the analysis of the phenolic substances that they biosynthesize. (MLH)

Suggests that the Friedel-Crafts reaction, used for synthesizing a wide range of aromatic compounds, is an ideal vehicle for extended senior high school project work in chemistry. Provides a theoretical discussion of the reaction, suggests a number of suitable investigations, and outlines the experimental details. (JR)

Provides abstracts and materials requirements for 20 chromatography projects. Experiments range in complexity; some require synthesis steps, apparatus construction, or special preparation techniques. (MLH)

Feeling that projects in chemistry could be used effectively to enhance appreciation of chemistry, a project-based course for the first-year sixth formers was developed in 1973 and because of its success another was organized. Projects from both courses are described. (EB)

An experiment is described in which undergraduate students can optimize the relative yield of sec-butylbenzene by varying molar ratio and temperature. (Author/SA)

Describes a project-oriented high school chemistry course that utilizes laboratory units in which the students make a practical product, such as soap, thus exposing them to career possibilities. (MLH)

Introduces an interdisciplinary activity using a cola drink. Describes the lesson plan, including objectives, procedures, evaluation, projects, and conclusions. Provides two laboratory sheets containing problem, hypothesis, materials, procedure, observations, and conclusions, vocabulary table, and data table. (YP)

Describes an advanced NMR project that can be done with a 60-MHz continuous-wave proton spectrometer. Points out the main purposes are to give students experience in second-order NMR analysis, the simplification of spectra by raising the frequency, and the effect of non-hydrogen nuclei on proton resonances. (MVL)

Discusses a laboratory technique of enzyme purification by affinity chromatography as part of an undergraduate biochemical methodology course. Provides preparation details of the rat muscle homogenate and reagents. Proposes column requirements and assaying information. (MVL)
