Simple, often artificial problems are normally preferred for introductory lab courses and are restricted to indoor participation. Microtitrations make it possible to leave the lab and study water chemistry directly in the natural environment. An exemplary outdoor challenge is presented here: travertine formation is context-rich, has to be examined…

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 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)

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)

Explores the selection, source, funding, time constraints, and community support involved in developing carefully planned and executed science projects. Lists 21 kinetics experiments noting the instrumentation needed and the original references. (MVL)
