This paper discusses historical events responsible for public awareness of the theory of evolution. Particular attention is placed on the discovery of a coelacanth (a type of fish), since it may have the greatest significance in convincing the public of the reality of evolution. Discusses implications for the teaching of evolution. (LZ)

Discusses the biodiversity crisis. Presents a simple invention to examine and photograph fish. (ASK)

Describes the care and breeding of zebra fish, suggests various experiments and observations easily performed in a classroom setting, and provides some ideas to further student interest and exploration of these organisms. (DDR)

Explains the fight or flight reaction and presents a hands-on activity for high school students. Uses crayfish behavior as an example. (Author/SOE)

Describes the construction of an inexpensive recirculating aquaculture system that can hold up to 46 pounds of fish, invertebrates, and mussels for classroom use. The system is versatile, requires little maintenance, and can be used for both teaching and research purposes. (WRM)

Discusses findings that suggest that mating preferences of female mottled sculpins (small North American fish) are influenced by at least four major factors, and that the relative importance of these factors changes through time. The type of choice that a female makes thus depends on time of breeding. (JN)

Describes a series of four experiments designed for small group involvement (each requiring 6 days) emphasizing students' scientific methodology. Topics include: feeding behavior; light/temperature effects on reproduction; effect of density on feeding; and altered male/female ratios on male behavior. Each experiment includes introduction, material…

Investigations that facilitate experimental design, the concept of replication, data analysis, and other aspects of scientific study are described. A list of materials, the recommended plants, and the directions for building the hydroponics unit are included. (KR)
