Predator-prey dynamics are an important concept in ecology, often serving as an introduction to the field of community ecology. However, these dynamics are difficult for students to observe directly. We describe a methodology that employs model caterpillars made of clay to estimate rates of predator attack on a prey species. This approach can be…

Reptiles and amphibians are a diverse and interesting group of organisms. The four activities described in this article take students' curiosity into the realm of scientific understanding. The activities involve the concepts of species identification; animal adaptations, communication, and habitat; and conservation. (Contains 1 table and 2…

Inspiring students to learn about birds can be a daunting task--students see birds just about every day and often don't think twice about them. The activity described here is designed to excite students to "become" birds. Students are asked to create a model and tell the life story of a bird by mapping its migration pattern. (Contains 6 figures, 6…

In this inquiry-based activity, Roborovsky hamsters are used to provide students with an opportunity to develop their skills of analysis, inquiry, and design. These hamsters are easy to maintain, yet offer students a means to use conventional techniques and those of their own design to make further observations through measuring, assessing, and…

In contemporary science education, the trend is to engage students in hands-on activities in which they must manipulate equipment and gather data in an effort to answer questions. Hands-on experiences may turn out to be meaningless unless the experiences are well designed, planned, and focused so that students are guided to construct accurate…

Describes having a pot-bellied pig in a classroom. Students learned how to care for the pig and train it. Describes other animals in the classroom and the class putting on shows for other students. (PR)

Describes a laboratory exercise in ethology that has proven to be successful in teaching the analytical power of biological observation to students at the University of Wisconsin. (JR)

Describes some ways that poetry can be used to present information about animals, enhance appreciation for animal habits and roles, and promote empathy for animals. Gives examples of and work sheets for the development of limericks, cinquain, haiku, and free verse. (TW)

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

Describes behaviors of the domestic cat in terms of developing students abilities to observe. Discussed are play, territoriality and pecking order, catnip, feral studies, and chasing. (CW)

An indirect procedure that uses the foraging behavior of animals at experimental food patches to address questions in animal behavior is discussed. Suggested projects that include the concepts of predation risk, harvest rates and metabolic costs, missed opportunity costs, and competition are described. (KR)

Summarizes how a group of teachers prepared a series of elementary-level inquiry experiences that focused on the study of land snails. Recommends and describes the K-W-L and Four Question inquiry strategies for younger and older students respectively. (WRM)

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.…

Activities are included that acquaint students with the parts of birds and the structure of feathers; that identify the prey of owls by opening owl pellets; working with information about threatened and endangered species of birds; and follow-up activities for bird study. A list of state and provincial birds of the United States and Canada and…

Discussed are the division of labor, defenses, genetics and evolution, communication, and navigation power of honeybees. The scientific and cross-curricular themes that can be offered using the economically important honeybee are described. Research that suggests that bees may be flying magnets is also discussed. (KR)
