Kurkdjian, Armen; And Others – American Biology Teacher, 1974
Describes several simple and inexpensive experiments designed to facilitate the study of normal and abnormal morphogenesis in the biology laboratory. Seedlings of the common garden pea are used in the experiments, and abnormal morphogenesis (tumors) are induced by a virulent strain of the crown-gall organism, Agrobacterium tumefaciens. (JR)

Coppage, Jo; Hill, T. A. – Journal of Biological Education, 1973
Experiments conducted on wheat and barley grains to analyze activities of alpha- and beta-amylase enzymes. Gibberellins were used exogenously. Techniques are described in detail. Results on different cultivars revealed that beta-amylase was not an invariable result of imbibition. Techniques employed can be used by school students. (PS)

Castellion, Mary E.; Bailar, John C., Jr. – Journal of Chemical Education, 1982
Clarifies misunderstanding of Millikan's experiment measuring charge on electrons. Most books describing the experiment indicate ionization of air in the apparatus caused liberation of electrons, and that these electrons were picked up by oil droplets. However, in Millikan's discussion, it is stated clearly that ions were attached to oil droplets.…

Grenville, H. W. – Journal of Biological Education, 1983
Offers suggestions for teaching some aspects of water economy in plants. These include diffusion/osmosis, water transport, the part played by turgor in structural support, and its implications for plant organs or whole plants. Several practical demonstrations/experiments are also described. (JN)

Brunet, Juan E.; And Others – Journal of Chemical Education, 1983
The continuous measurement of oxygen consumption in an enzymatic reaction is a frequent experimental fact and extremely important in the enzymatic activity of oxygenase. An electrochemical system, based on a polarographic method, has been developed to monitor the oxygen uptake. The system developed and electrode used are described. (JN)

Mathias, Lon J. – Journal of Chemical Education, 1983
Suggested guidelines and representative experiments for a one-semester introductory polymer chemistry laboratory course are provided. Experiments, which provide students with both synthetic and characterization experiences, require a minimum of special equipment and student skills. Includes list of 83 experiments, demonstrations, and reference…
