A technique is presented which utilizes wax moth larvae in a laboratory investigation of an insect virus. Describes how an insect virus can be used to introduce undergraduate biology students to laboratory work on viruses and several virological concepts. (SA)

Describes a rapid staining technique for investigating the anatomical expression of two recessive genes. The demonstration is intended to stimulate students who are interested in the practical applications of genetics. (Author/SA)

Basic marine aquaria equipment, techniques for maintenance, specimens and food for the marine organisms are discussed. Several sources of specimens are included. (SA)

Background information and procedures for demonstrating physical phenomena to groups are described: a red plastic sheet that changes to blue, a group activity for understanding energy transfer, and hanging a spoon from one's nose to illustrate forces involved in static equilibrium. (SK)

Outlined are procedures for using satellites including the mechanics (plotting satellite positions and obtaining readable signals) and secondary and college activities (using Oscar 8 data telemetry, obtaining weather pictures, using a computer). (DC)

Provides background information and teaching suggestions for collecting and using lichens in the classroom and for conducting field investigations. Focuses on structure, reproduction, photosynthesis, and effects of air pollution. (DC)

Reviews a K-6 elementary science program entitled "Health Science" (D.C. Health), describing the content and format of student texts and teacher's guides and the nature of the activities. (DC)

Five atomic theory activities feasible for high school students to perform are described based on the following models: (1) Dalton's Uniform Sphere Model; (2) Thomson's Raisin Pudding Model; (3) Rutherford's Nuclear Model; (4) Bohr's Energy Level Model, and (5) Orbital Model from quantum mechanics. (SK)

Presents 15 suggestions for planning successful science fairs with younger children. Includes a list of ways in which the library can help. (SK)

Describes a lysozyme assay for use in the biology classroom to teach enzymology. Provides background information, materials and methods, sources of lysozyme, and evaluation of the assay. (DS)

Presents a new department in this journal titled "Biology Olympics." Presents justification for this department and discusses the first three "challenges" focusing on: (1) model-building, (2) plant biology, and (3) human biology. (DS)

Materials and methods for studying the functioning and responses of stomatal guard cells are described. (PB)

Outlined is a water ecology unit included within a one-semester field biology course for upper level high school students. Activities described include a visit to a water treatment plant, an abiotic stream study, a biotic stream study, interactions and questioning topics, and individual projects. (CS)

Discusses the use of games in the classroom. Describes two games involving the identification of Australian animals including complete instructions and rules for each game. (DS)

Presents a method for calculating age specific expectation of life for human populations by examining obituary entries in newspapers, tombstones, and parish records. Examples are given which illustrate large differences between the sexes, social classes, and dates at a given locality. (Author/CS)
