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 reviewedFalk, Peter – School Science Review, 1973
Describes demonstrations suitable for secondary school biology classes relating to the effects of the hormone IAA on plant growth. Demonstrations illustrate how hormone treatments affect stem elongation, callus formation, inhibition of axillary buds, stimulation of secondary growth and initiation of adventitious root development, root elongation,…
Descriptors: Biology, Demonstrations (Educational), Instructional Materials, Laboratory Procedures
Peer reviewedDonaldson, G. B. – Physics Education, 1973
Describes the construction and operational procedures of a simple setup which enables undergraduate students to conduct experiments on critical phenomena in gases. Indicates that the experimental features are proved comparable to those of the Reamer and Sage apparatus. (CC)
Descriptors: College Science, Electric Circuits, Kinetic Molecular Theory, Laboratory Equipment
Peer reviewedWarren, S. E. – Physics Education, 1973
Descriptors: College Science, Cooperative Programs, Educational Programs, Industrial Training
Peer reviewedCockcroft, W. E. Lawson – Journal of Chemical Education, 1973
