In the present study, a preparation of frog skin was presented, which can be used to demonstrate the basic concepts of blood flow regulation in a very clear and attractive way to high school and university students. In a freshly euthanized "Xenopus," a patch of abdominal skin was exposed from the internal side and viewed with a USB…

In this article, the authors describe their ongoing experience with the Herpetology Project. Through this field study, students catch and track amphibians and reptiles in the Assabet River area, record and analyze data, share their findings with the community, and ultimately, work toward protecting turtles' habitats. The authors chose to focus on…

Understanding how geckos--small lizards belonging to the family "Gekkonindae"--can "defy gravity" and walk across a ceiling provides a fascinating frame through which students can not only learn valuable content about electrostatic forces, but also engage in authentic scientific practice and explore new technologies based on gecko adhesion. In…

The distinctive character of this work consists in the treatment of the whole Animal Kingdom as a unit; in the comparative study of the development and variations of organs and their functions, from the simplest to the most complex state; in withholding Systematic Zoology until the student has mastered those structural affinities upon which true…

Recommends that teacher and student be provided with the broadest possible spectrum of meaningful and feasible experiments in which the comfort of the experimental animal is protected by the design of the experiment. (BR)

Provided is a dichotomous key to the families of marine fish commonly taken aboard the Orange County Schools Marine Science Floating Laboratory. This key has been designed for use by junior and senior high school students. Diagrams and drawings are provided which indicate diagnostic characteristics of various members of the fish families included.…

Information on the morphology of tapeworms (cestoidea) is provided. A transparency master illustrating the general structure of the worms is also provided. (JN)

The study examines the interests and attitudes of school students toward biology: through their interest in out-of-school activities and their attitude towards lessons as measured by interest, importance and difficulty. Biology lessons were relatively popular with the greatest preference found among students learning zoology. Girls showed…

The relationship between tadpoles, algae and drinking water for wildlife is discussed. Six projects that students can do to learn more about the ecological benefits of tadpoles and frogs are described. A bibliography is included. (AJ)

Provides examples of animals in which growth occurs without cell division. Indicates that this phenomenon (called cell constancy or eutely) is an oddity of development that has arisen independently in several animal groups. (JN)
