Experiments are described on collisions between two billiard balls and between a bat and a ball. The experiments are designed to extend a student's understanding of collision events and could be used either as a classroom demonstration or for a student project.

A laboratory experiment is described in which a simple characterization of a historical lime mortar is made by the determination of its approximate composition by a gravimetric method. Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) are also used for the qualitative characterization of the lime mortar components. These…

The measurement of the force acting between two parallel, current-carrying wires is known as Ampère's experiment. A mechanical balance was historically employed to measure that force. We report a simple experiment based on an electronic precision balance that is useful in clearly showing students the existence of this interaction and how to…

Help children identify and use two basic elements in the scientific process. (Editor)

Engaging students in science learning can be challenging, and incorporating new forms of technology into science has been shown to provide creative learning experiences. However most technology enhanced learning and e-Science experiences to date have been designed and run by researchers. There is significant challenge in moving these experiences…

An updated version of "Mr. Wizard" is returning to television three times a week on Nickelodeon, the cable network for children. Highlights the career of Don Herbert (who is Mr. Wizard) and his experiences with "Mr. Wizard" television programs. (JN)

Describes a sequence of experiments developed at Texas A&M University for use in one-semester and two-semester (nonmajors) organic chemistry courses to teach a maximum number of separation and purification techniques such as distillations, recrystallization, liquid-liquid extraction, and chromatography. (SK)

Describes a one-year program in which students are given lectures on instrumentation topics, acquire experience participating in campus and community laboratories, and complete individual projects to receive the master's degree. Indicates a high ability of attacking laboratory problems in students' achievement. (CC)

Describes a chemistry program in which experiments are performed for students in grades one to three. The experiments use only materials and apparatus found in the average home so they can be reported by teachers or parents. Students become involved in the program by asking questions and making predictions. (JN)

In the 20 years since the inauguraion of "Jugend forscht" (Young Researchers) over 26,000 boys and girls have taken part in this annual Olympiad of young innovators. This brochure gives an insight into the diversity of themes dealt with by the "Jufos" (young researchers) and into their ability to achieve astonishing…

The Search for Excellence in Science Education (SESE) project gives national recognition to outstanding science programs. Descriptions of five high school physics programs selected by SESE are provided. Unique aspects of the programs, instructional strategies, and other areas are included. (BC)

Describes the implementation of the National Aeronautics and Space Administration SEEDS Project in a sixth-grade class in Turlock, California. Describes student activities and media coverage surrounding the project. (MDH)

FEMME (Females in Engineering, Methods, Motivation, Experience) is a pre-college summer program for 25 bright and gifted ninth-grade females who like mathematics and science. This program, now in its fourth year, is described, providing information about program goals, operation, trips, student laboratory experiments, and topics discussed by guest…

Traces the history of physiology at the University of Michigan, focusing on facilities, curriculum program and instruction, classic experiments, and faculty. Contributions of Henry Sewall and Warren Plimpton Lombard are discussed at some length. (JN)
