This study aimed to develop, introduce, and conduct an inquiry-driven creative drama activity. The activity, for elementary students, related to the transmission of light and full shadow. In the activity, which consisted of a warm-up, dramatization, and evaluation stages, two inquiry-based experiments were added to the dramatization stage. Thus,…

Analyzing evolutionary relationships requires that students have a thorough understanding of evidence and of how scientists use evidence to develop these relationships. In this lesson sequence, students work in groups to process many different lines of evidence of evolutionary relationships between ungulates, then construct a scientific argument…

The ocean provides humanity with many services and goods, including clean air, minerals, and food. Sustainable use and management of our marine resources are important to ensure that these resources are available for future generations. The turn-based activity presented in this article teaches students the challenges of managing a sustainable…

"Yuuuck!" "Gross!" "Cool!" The response to slugs is never indifference. These slimy creatures are perfect for captivating students' imagination and curiosity, and they are ideal subjects to introduce investigative science. This article describes a classroom activity in which students design a research investigation to answer the question: "Is slug…

There is a particular need for inquiry-based lessons in the early elementary grades, when students are starting to develop their analytical skills. In this article, the authors present a 2-tiered inquiry-based lesson plan for 1st and 2nd grades that has been successfully used by graduate teaching fellows involved in the National Science Foundation…

Mutational inactivation of a specific gene is the most powerful technique to analyze the biological function of the gene. This approach has been used for a long time in viruses, bacteria, yeast, and fruit fly, but looked quite hopeless in more complex organisms. Targeted inactivation of specific genes (also known as knock-out mutation) in mice is…

Cognition is a general term describing the mental capacities of an animal, and often includes the ability to categorize, remember, and communicate about objects in the environment. Numerous regions of the telencephalon (cerebral cortex and limbic system) are responsible for these cognitive functions. Although many researchers have used traditional…

Presents activities that use marine organisms with plant-like appearances to help students build classification skills and illustrate some of the less obvious differences between plants and animals. Compares mechanisms by which sessile plants and animals deal with common problems such as obtaining energy, defending themselves, successfully…

Describes a sophisticated version of the fruit fly experiment for teaching concepts about genetics to biology students. Provides students with the opportunity to work with live animals over an extended period. (JRH)

The main objective of this class experiment is to measure the activity of two metabolic enzymes in crude extract from bird pectoral muscle and to relate the differences to their mode of locomotion and ecology. The laboratory is adapted to stimulate the interest of wildlife management students to biochemistry. The enzymatic activities of cytochrome…

Accidentally killed animals provide biology classes with excellent study material. (Editor)

Animals Alive! is designed to help teachers develop an inquiry-oriented program for studying the animal kingdom in which, whenever possible, live animals are collected locally, studied, observed, and then released completely unharmed back into their natural habitats. By careful selection and modification of the chapter questions, activities, and…

Describes content and conduct of a course that deals with animal use. Exposes students to a variety of perspectives from extreme to moderate concerning uses and abuses of animals. Appendix lists resources for animal uses and abuses seminar. (JRH)

Presents three science activities targeted to help urban students learn about nature: (1) observing coloration patterns of pigeons; (2) measuring local rainfall and comparing it to other areas; and (3) conducting a biodiversity study by observing a patch of lawn. (YDS)

Nine lessons which involve the use of marine organisms in the classroom are presented in this seventh-grade biology unit. The unit offers instructors alternative ways of meeting common life science goals. It is not meant to be an extra curriculum added to the normal course load, but was developed to consolidate a group of activities designed for…
