Illert, C. – South Australian Science Teachers Journal, 1973
Discusses phenomena relating to the nature of soap films and describes soap film experiments suitable for secondary school science students. (JR)
Descriptors: Laboratory Experiments, Laboratory Procedures, Physical Sciences, Physics
Peer reviewedTait, A., Ed. – Australian Science Teachers Journal, 1973
Descriptors: Biology, Chemistry, Instructional Materials, Laboratory Experiments
Peer reviewedBergsten, Ronald – American Journal of Physics, 1974
Discusses the production and structure of a sequence of optical crystals which can serve as one-, two-, and three-dimensional diffraction plates to illustrate diffraction patterns by using light rather than x-rays or particles. Applications to qualitative presentations of Laue theory at the secondary and college levels are recommended. (CC)
Descriptors: College Science, Demonstrations (Educational), Equipment Utilization, Instrumentation
Peer reviewedHart, Francis X. – American Journal of Physics, 1974
Discusses an experiment which introduces students to the effects of electrical forces on the motion of macroscopic objects. Included are the proecedures of measuring the charge-to-mass ratio from deflections of charged water drops in horizontal fields and the overall charges delivered in a Faraday cup. (CC)
Descriptors: College Science, Instruction, Instructional Materials, Laboratory Equipment
Peer reviewedKiszenick, Walter; Wainfan, Nathan – American Journal of Physics, 1974
Descriptors: College Science, Instructional Materials, Laboratory Equipment, Laboratory Experiments
Peer reviewedHeald, Mark A. – American Journal of Physics, 1974
Discusses a simplified Millikan oil-drop experiment which emphasizes the enplanation of basic concepts in mechanics and electrostatics, the use of home-made apparatus, the request for an individual's observation of his own drop, and the application of statistical analysis in data interpretation. (CC)

Peer reviewedGarmendia, Angel A.; And Others – Journal of Chemical Education, 1973
Descriptors: Chemistry, College Science, Instructional Materials, Laboratory Experiments
Peer reviewedSchmidt, Hans-Jurgen – School Science Review, 1973
Discusses the importance of ethene (ethylene) in industry and the pipeline grid in western Europe for transporting ethene. Describes methods for investigating organic compounds in school laboratories using ethene as the key compound. (JR)
Descriptors: Chemical Analysis, Chemistry, Laboratory Experiments, Laboratory Procedures
Peer reviewedRobinson, M. L. A.; Saunders, A. P. – School Science Review, 1973
Discusses holography, a process by which a three-dimensional image of an object can be completely recorded on a photographic film or plate. Introduces hologram theory with a view to presenting it to senior high school students, and explains how the apparently very great experimental difficulties can be overcome. (JR)
Descriptors: Holography, Laboratory Experiments, Laboratory Procedures, Lasers
Peer reviewedWilliams, R. J.; Ladd, G. F. – School Science Review, 1973
Describes animal behavior experiments that can be easily performed by secondary school students. The experiments illustrate territorial behavior, social order, and exploratory behavior in Mongolian gerbils. (JR)
Descriptors: Animal Behavior, Behavior Patterns, Biology, Laboratory Experiments
Peer reviewedRose, T. L.; Seyse, R. J. – Journal of Chemical Education, 1974
Discusses the development of a one-year laboratory course in an effort to provide a link between traditional laboratories devoted to a single area of chemistry and the total involvement of a single narrow research project. Included are outlines of 32-hour lectures and 11 experiments performed in the integrated course. (CC)
