This activity package is designed as a resource for the classroom teacher. It contains numerous activities, experiments, and demonstrations in environmental education for the elementary grades. Numerous field trips are described. Each activity includes: objectives, suggested materials, suggested methods, and a description of the activity. Where…

Ten experiments and 27 activities are presented in this handbook. The experiments are related to collisions, energy conservation, speed measurements, thermometry, calorimetry, gas properties, wave motions, and acoustic problems. The activities are concerned with stroboscopic photographs in collision, elastic impact, mass conservation, exchange of…

Up-to-date knowledge about Skylab experiments is presented for the purpose of informing high school teachers about scientific research performed in orbit and enabling them to broaden their scope of material selection. The first volume is concerned with the solar astronomy program. The related fields are physics, electronics, biology, chemistry,…

This paper outlines a project for developing a comprehensive volume devoted to concrete teaching ideas, resources, strategies, and activities relating to science education for elementary school students and teachers. An extensive bibliography of existing references on science activities and resources is included. (SL)

This freshman chemistry lab relates stoichiometric problems to real situations. It requires students to measure the Fe impurity in reagent grade calcium chloride. (BB)

This experiment provides an excellent practical application of computer-controlled spectrometers. (BB)

Discusses briefly Piaget's views on intellectual development as related to science teaching. Describes intellectual activities observed in science classrooms and shows how specific science lessons can be designed to encourage cognitive development. (GA)

In this experiment, the observation that, for meta- and para-substituted styrene derivatives, the magnitude of the C-13 shielding value for the beta-carbon is linearly related to sigma for the ring substituent is used to determine sigma. (BB)

In one option for this project, the rotation-vibration infrared spectra of a number of gaseous diatomic molecules were recorded, from which the fundamental vibrational wavenumber, the force constant, the rotation-vibration interaction constant, the equilibrium rotational constant, and the equilibrium internuclear distance were determined.…

Explains a laboratory exercise where 2-methylpyrazinepentacyanoiron (II) is synthesized by thermal and photochemical pathways. (GA)

Describes three simple experiments using Fermat's principle; a single reflection, Schwarz's triangle problem, and light triangle inscribed inside a circle. (GA)

Presents the following chemistry lecture demonstrations and experiments: (1) a versatile kinetic demonstration; (2) the Bakelite Demonstration; (3) applying Beer's law; and (4) entropy calculations. (HM)

Video cassette demonstrations are useful in teaching experimental techniques and instrumentation. This article describes how the recorded demonstrations save instructor and student time, how they can be integrated into a multimedia teaching format, and how recordings support student independence. (Author/BB)

Describes an experiment based on Faraday's one-piece generator, where the rotating disk is replaced by a cylindrical permanent magnet. Explains the apparent paradox that an observer in an inertial frame could measure his absolute velocity. (GA)

Describes an electroplating experiment which utilizes photovoltaic (solar) cells to drive the chemical reaction. (SL)
