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

In the present study, we analyze activities on the topic of sound, which are performed in the science education laboratory lessons in the third-year students of the Department of Early Childhood Education at the University of Ioannina. The analysis of the activities is based on one of the most modern learning theories of CHAT (Cultural Historical…

Details construction of an inexpensive electronic auditory device in which the resistance in parallel with the device is inversely proportional to the frequency of sound produced. (CP)

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)

Describes a student investigation of a reverse flame in a atmosphere of methane that won second place in the physics division of the International Science and Engineering Fair. Includes a discussion of falling and fracturing behavior, specifically dealing with chimneys, trees, pencil point, stirring rods, and chalk. (BT)

We describe a third-year undergraduate course that focuses on multiscale modeling and protein folding and has as its primary goal the encouragement of students to integrate thinking across and beyond disciplinary boundaries. The ability to perform innovative and successful research work in STEM (science, technology, engineering, and mathematics)…

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

Discusses the educational values of participating in science fairs, and outlines the procedure used at Saint Ursula Academy, Toledo, to interest each biology student in an individual investigation. (JR)

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)

Describes two experiments in physics, using the same inexpensive apparatus, that may be performed as projects by high ability secondary science students. (JR)
