Scadding, Steven R. – Journal of Biological Education, 1984
A simple method of studying thyroxine-induced resorption of tadpole tails in vitro is described. This procedure demonstrates that resorption is dependent on thyroxine and requires protein synthesis. It introduces students to the use of tissue culture methods. (Author)

Gill, John; Badcock, Margaret – Journal of Biological Education, 1990
Presented is a cytogenic technique which enables students to produce preparations of dividing cells. Described are materials, methods, typical results, and assessment for this activity. The usefulness for a wide range of ages and abilities is stressed. (CW)

Ianuzzo, C. David; And Others – Journal of Biological Education, 1987
Describes an experiment which demonstrates the association of particular metabolic biochemical changes and muscular fatigue. Highlights applications related to cellular energy metabolism, metabolic regulation, and muscle energetics. (ML)

Freeman, H. E. – Journal of Biological Education, 1985
Thin slices of potato can be used to demonstrate the presence of protein, carbohydrates, and nucleic acids at the cellular level. Procedures and materials are provided for these simple tests. Also indicates that the presence of fat can be readily seen by staining avocado with Sudan red or Sudan black. (Author/DH)

Freeman, H. E. – Journal of Biological Education, 1984
Two methods for examining leaf structure are presented; both methods involve use of "superglue." The first method uses the glue to form a thin, permanent, direct replica of a leaf surface on a microscope slide. The second method uses the glue to examine the three-dimensional structure of spongy mesophyll. (JN)

Cochrane, William; Dockerty, Alex – Journal of Biological Education, 1984
Suggests that many textbooks intended as standard A-level texts contain accounts of DNA synthesis which are out of date, and in some cases, contain unhelpful or misleading simplifications. An outline of recommended materials and guidelines on how recent advances aid the understanding of this process are presented. (Author/JN)

Gayford, C. G. – Journal of Biological Education, 1984
Discusses concepts needed to understand plant water relations and results of a study designed to examine the understanding of these concepts by students preparing for A-level examinations. Focuses on students who have learned the topic using the old terminology compared with students adopting the new suggested terms. (Author/JN)

Bery, Julia – Journal of Biological Education, 1985
Describes a demonstration designed to help students better understand the response of plant and animal cells to hypotonic solutions. The demonstration uses a balloon inside a flexible, thin-walled cardboard box. Air going in corresponds to water entering by osmosis, and, like real cells, if stretched enough, the balloon will burst. (DH)

Dreyfus, Amos; Jungwirth, Ehud – Journal of Biological Education, 1989
The results of survey of secondary school biology students used to access misconceptions about cells are presented. A distinction between conceptions, misconceptions, and nonconceptions is drawn in terms of secondary school biology concepts. The resilience of misconceptions is discussed. (CW)

Newton, M. E. – Journal of Biological Education, 1985
Describes procedures (recommended for both secondary and college levels) to study mitosis, Giemsa C-banding, reproductive phenomena (including alternation of generations), and phototropism in mosses and liverworts. (JN)
