Part three of a series on the teaching of evolution, this installment focuses on the Scopes trial and litigation in other states and courts. Contains 46 references. (DDR)

Discusses some new evidence for evolution that might be useful in persuading students who question the scientific basis for evolution. Draws on findings from the fields of molecular biology and genetics. (DDR)

Provides directions for the construction of giant plastic cells, including details for building and installing the organelles. Also contains instructions for preparing the ribosomes, nucleolus, nucleus, and mitochondria. (DDR)

Describes an extended role-playing game for middle school to post-secondary students centered around the sale of a forest and farm in Costa Rica. Takes an in-depth look at the question of what it takes to purchase and protect a tropical forest. (DDR)

Reports on the development of a laboratory exercise that would allow students to explore the concept of genetic drift. Discusses the concept of genetic drift that is coincident with natural selection and that closely models the real world. (DDR)

Details the active-learning approach to teaching cellular respiration in an introductory, one-semester course for nonmajors. Focuses on a laboratory exercise designed to answer the question of what happens to food when eaten. Contains 19 references. (DDR)

Presents an activity that involves the collection and analysis of biological data, research into the social and medical history of a community, and the development of skills in oral and written communication. (DDR)

Describes a laboratory procedure using vanilla and chocolate sandwich cookies that can be used to illustrate independent assortment either during meiosis or during a dihybrid cross. (DDR)

Argues for the use of procedures known as clearing and double staining to clear soft tissues and differentially stain cartilage and bone in specimens. Describes each step of the process. (DDR)

Discusses an 84-question survey administered to a random sample of Pennsylvania school districts focusing on the Christian community which has voiced the most concerns about teaching evolution in the schools. Thirty-nine percent of responding high school teachers felt creation science should be taught in the public school. Comparisons are also…

Reports on the attitude variations between students who had direct experiences with another living thing and those who did not. All students who had direct experiences with another living thing showed a higher mean value in all the attitude categories that showed more concern for another species. Confirms the importance of students having direct…

Describes a laboratory project for first-year biology students that examines competition among various cellular slime molds. After a brief introduction to the topic of competition and basic life history information about cellular slime molds, students choose a question and design original experiments to seek an answer. (Author/AIM)

Describes an experiment using a plant pathogenic fungus in which students learn to follow aseptic techniques, grow and produce spores of a fungus, use a hemacytometer for enumerating spores, prepare serial dilutions, grow and inoculate plants, isolate a pure culture using agar streak plates, and demonstrate the four steps of Koch's postulates.…

Explains the allium test in which roots are excised from onion bulblets grown in aqueous solutions of a test agent. Root tips are then isolated and stained with aceto-orcein, and chromosomal aberrations are microscopically observed. (Author/AIM)

Presents an exercise to demonstrate two fundamental concepts of fluid mechanics: the Reynolds number and the Principle of Continuity. The exercise demonstrates flow in a major blood vessel, such as the aorta, with and without a stenosis. Students observe the transition from laminar to turbulent flow as well as downstream persistence of turbulence.…
