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…

With 101 easy and inexpensive activities to do on school grounds, "Schoolyard Science" can help students develop their observation and inquiry skills as well as an appreciation of their outdoor environment. Covering topics such as lower plants, gardens, insects and other invertebrates, energy, and Earth science, Thomas Lord and Holly Travis…

In this activity, Namib and Antarctic arthropods are used to illustrate several important biological principles. Among these are the key ideas that form follows function and that the environment drives evolution. In addition, students will discover that the climates of the Namib Desert and the Antarctic Peninsula are similar in several ways, and…

Provided are suggestions for student investigations of life in swift stream communities, in slow stream areas and near a spring. (PEB)

Presents a laboratory experiment that examines the aggressive behavior of male paradise fish. Students design the experiment, collect data, and analyze and interpret the results. This activity is appropriate for biology, ecology, and animal behavior classes and allows students to be involved in the entire scientific process. (Author/NB)

The recent promotion of inquiry-based learning techniques (Uno, 1990) is well suited to the use of animals in the classroom. Working with living organisms directly engages students and stimulates them to actively participate in the learning process. Students develop a greater appreciation for living things, the natural world, and their impact on…

Provides (1) background information on the many ways birds keep fit and are adapted to survive; (2) student activities on this topic; and (3) ready-to-copy materials (a game, worksheet, and coloring pages). Each activity includes an objective, recommended age level(s), subject area(s), list of materials needed, and procedures. (JN)

"Bug City" is a video series created to help children (grades 1-6) learn about insects and other small critters. All aspects of bug life are touched upon including body structure, food, habitat, life cycle, mating habits, camouflage, mutualism (symbiosis), adaptations, social behavior, and more. Each program features dramatic microscopic…

Described is the use of praying mantises as organisms to illustrate the concept of predator. (PEB)

Describes procedures for collecting and using cryptozoic invertebrates in introductory biology classes to develop interest in invertebrate ecology, behavior, physiology, morphology, and taxonomy. (PEB)

Mammals that tolerate the winter cold and stay active all year exploit the harsh northern climate to their advantage. By simple experiments and observation you can better understand their adaptations which include furry bodies, snowshoe feet, extra blubber, light coloration, and strategically distributed food caches.

All aspects of bug life are touched upon including body structure, food, habitat, life cycle, mating habits, camouflage, mutualism (symbiosis), adaptations, social behavior, and more. Each program features dramatic microscopic photography,…

Discussed is an activity designed to teach small mammal ecology and the scientific method using fluorescent dyes and pigments. Procedures for analyzing home ranges and social organizations are described. A list of 16 references is included. (CW)
