This paper focuses on the search for electromagnetic induction from 1820 to 1831 and the efforts by Augustin Fresnel's colleague, Andre Marie Ampere, in electric and magnetic induction. Faraday's work is discussed with excerpts from his diary on electromagnetism. A variety of different experiments by researchers including Francoise Jean Arago,…

This paper focuses on Michael Faraday's experimental research in electricity in the 1830's. Historical notes related to his work are included as well as experiments, his objectives, and illustrations of equipment for the experiments. Examples from his diary are given so that students can attempt to emulate his honest and systematic manner of…

Reported is a study to investigate the effects of a free-choice program on children's ability to interpret experiments, design simple investigations, and recognize variables that could affect the outcome of observed events. (Author/SA)

This study describes children's learning in a free-choice environment. Teacher controlled instruction is minimized and children participate in a wide variety of science activities with equipment that is selected by each individual student. The study occurs within an elementary school's Science Enrichment Center and the children work on the…

A SERIES OF EXPERIMENTS WAS CONDUCTED TO TEST THE EFFECTIVENESS OF TELEVISED INSTRUCTION. THIS STUDY, THE SEVENTH IN A SERIES, EVALUATED THE EFFECTIVENESS OF THREE PROCEDURES TO STIMULATE STUDENT EXTRACURRICULAR SCIENCE ACTIVITIES. IN THE FIRST PROCEDURE THE PRESENTATION METHOD, ADULT INSTRUCTORS PERFORMED THE EXPERIMENTS IN ONE VERSION AND…

In the Skylab student project, high school students submitted proposals for experiments that could be performed on board Skylab by the astronauts. This book describes the experiments designed by the students and reports what happened to those experiments in the space laboratory. The student experiments included studies of the central nervous…

Basic knowledge about Skylab experiments is presented in this book for the purpose of informing high school teachers about scientific research performed in orbit and enabling the teachers to broaden their scope of material selection. The seventh volume deals with the ability of the Skylab crew to live and work effectively in space. The content is…

Presents a list of Biology-A level projects submitted for the Oxford and Cambridge Board examination by pupils of Uppingham School in the United Kingdom. (HM)

An experiment is described which uses lead sulfide to illustrate the concept of definite proportions as well as the union of atoms to form compounds. This experiment has been successfully used with ninth graders. The advantages of this experimental procedure over available alternatives are listed. (MR)

Describes a junior high school level exercise using plant pigments as acid-base indicators. (SL)

Discusses the range of wavelengths of the electromagnetic spectrum considered to be the visible portion. Describes a demonstration designed to help students understand the relation between the wavelength measurements on a spectrophotometer such as the Spectronic 20 and the actual colors of light being used. (TW)

Explains: (1) use of piezoelectric film (connected to power supply and oscilloscope) to reveal force-versus-time curves of bouncing balls; (2) use of bound wood splints or meter sticks to illustrate tree or tower stability; and (3) apparatus of co-axial discs with connected linking rods and suspended bobs to simulate waves. (DH)

Discusses electron-loss spectroscopy and the experimentally observed excitation energies in terms of qualitative MO theory. Reviews information on photoelectron spectroscopy and electron transmission spectroscopy and their relation to the occupied and unoccupied orbital levels. Focuses on teaching applications. (ML)

Describes a physical organic experiment in thermodynamics and kinetics for undergraduate courses in organic chemistry, biochemistry, or physical chemistry. Details background information, solution preparations, equipment and methods, and the suggested experiments such as determination of general-base-catalytic coefficients and the Bronsted…

Describes two introductory exercises designed to teach the fundamental ideas and methods of crystallography, and to convey some important features of inorganic and organic crystal structures to students in an advanced laboratory course. Exercises include "The Crystal Structure of NiO" and "The Crystal Structure of Beta-Fumaric Acid." (CW)
