Describes three experiments for undergraduates which illustrate associations of parasites with their host. Includes a table of parasite-induced alterations of selected host species. Instructional suggestions are also provided. (ML)

Background information on the biology of aphids is supplied. Using this information in a wide variety of investigations, many involving equipment and techniques available in the school laboratory, can be carried out. An appendix lists possible projects. (Author)

Presents a set of hands-on, outdoor science experiments designed to teach elementary school students about animal adaptation. The experiments focus on: how color camouflage affects an insect population; how spiderlings find a home; and how chameleons camouflage themselves by changing color. (SM)

Suggests using African-clawed frogs (Xenopus laevis) for conditioning (behavior) experiments. Other experiments using these easy-to-care-for frogs are outlined. (JN)

Presents 2 activities for students aged 8-12 in which students determine (1) whether or not earthworms can see white light; and (2) how an earthworm moves without legs. (MDH)

Provided is a high school activity in which students observe the filter feeding of barnacles and the effects of a variety of changing parameters upon their feeding process. Includes list of materials needed and procedures necessary to accomplish the activity. (JN)

The carabid beetle (Notiophilus) preys readily on an easily-cultured collembolan in simple experimental conditions. Some features of this predator-prey system are outlined to emphasize its use in biology instruction. Experiments with another potential collembolan are described in the context of developing the method for more advanced studies.…

Ideas related to including ethology in high school biology programs are given. The methods of ethology and tips on how to communicate observations are briefly explained. (SA)

Described are the basic materials and procedures used to study defensive burying behavior and suggested laboratory projects. Discusses live targets, non-living targets, social variables, and previous experiences of the subjects. (CW)

Describes ways platyfish can be utilized in biology activities and experiments. Includes an account of the animals' care, unique anatomical characteristics, reproductive behavior, and genetics. (DS)

Provides examples of several classroom activities utilizing the American horseshoe crab (Limulus Polyphemus), including raising fertilized eggs, fertilizing eggs in vitro, and testing water samples. Includes background information on the natural history, life cycle, and breeding habits of this animal. (DS)

Use of motion pictures and videotape recordings to analyze animal behavior is described. Indicates that accuracy/amount of data available is greatly increased and that simultaneous behaviors of different animals can be studied or individual behavior patterns increased/decreased, providing observers with temporal perceptions similar to the animals…

Presented are five ideas for A-level biology experiments using a laboratory computer interface. Topics investigated include photosynthesis, yeast growth, animal movements, pulse rates, and oxygen consumption and production by organisms. Includes instructions specific to the BBC computer system. (CW)

The use of live animals in the secondary school laboratory is discussed along with suggestions for increasing the use of live animals and challenges to those teachers who restrict this use. (SA)

Describes a number of laboratory experiments using woodlice as experimental animals. Includes topics such as physiology of water relations, behavior, and rhythmic activity. (CS)
