Lenning, Elizabeth; Rudge, David – American Biology Teacher, 2023
The discovery of and research into penicillin resistance by Sir Edward Abraham and Sir Ernst Chain can be used to teach the concept of natural selection and also multiple nature of science (NOS) objectives associated with Next Generation Science Standards, such as "scientific knowledge is based on empirical evidence" and "science is…

Work, Kirsten A.; Gibbs, Melissa A.; Friedman, Erich J. – American Biology Teacher, 2015
We describe a card game that helps introductory biology students understand the basics of the immune response to pathogens. Students simulate the steps of the immune response with cards that represent the pathogens and the cells and molecules mobilized by the immune system. In the process, they learn the similarities and differences between the…

Valauri-Orton, Alexis; Bernd, Karen K. – American Biology Teacher, 2015
For many middle school students, connections between their lives and concepts like chemical reactivity, microbial contamination, and experimental sampling are not obvious. They may also feel that, even if there were connections, understanding the monitoring and quality of natural resources is something for grown-ups and beyond their…

McKernan, Lisa N. – American Biology Teacher, 2015
The challenge of teaching in the sciences is not only conveying knowledge in the discipline, but also developing essential critical thinking, data analysis, and scientific writing skills. I outline an exercise that can be done easily as part of a microbiology laboratory course. It teaches the nature of the research process, from asking questions…

Lennox, John; Ashe, Jeffrey – American Biology Teacher, 2009
In a climate of increased concern for the environment and its protection, teachers in disciplines as diverse as biology, microbiology, environmental studies, and environmental engineering may be seeking teaching materials and laboratory exercises that will enable them to introduce these new concepts into their classrooms and laboratories. The…

Johnson, Nancy C.; Chaudhary, V. Bala; Hoeksema, Jason D.; Moore, John C.; Pringle, Anne; Umbanhowar, James A.; Wilson, Gail W. T. – American Biology Teacher, 2009
Biology curricula cover fungi in units on bacteria, protists, and primitive plants, but fungi are more closely related to animals than to bacteria or plants. Like animals, fungi are heterotrophs and cannot create their own food; but, like plants, fungi have cell walls, and are for the most part immobile. Most species of fungi have a filamentous…

Serafini, Amanda; Matthews, Dorothy M. – American Biology Teacher, 2009
Natural selection is the mechanism of evolution caused by the environmental selection of organisms most fit to reproduce, sometimes explained as "survival of the fittest." An example of evolution by natural selection is the development of bacteria that are resistant to antimicrobial agents as a result of exposure to these agents. Triclosan, which…

Ross, Pauline M.; Tronson, Deidre A.; Ritchie, Raymond J. – American Biology Teacher, 2008
Cellular respiration and metabolism are topics that are reportedly poorly understood by students and judged to be difficult by many teachers. Although these topics may not be required learning areas in some high school biology curricula, a grasp of fundamental concepts of cellular metabolic processes is advantageous for students undertaking (or…

Dahl, John; Mixter, Phil – American Biology Teacher, 2008
In delivering a core science course to pre-health-related majors, the authors sought ways to engage students, make material relevant to life-long learning, and present it in a memorable way. Their goals were to present scientific content fused with history, ethics, public policy, and art in such a way that the students would be provided a unique…

Dunnivant, Frank M. – American Biology Teacher, 2006
Most chemistry and biology teachers will agree that students have a "disconnect" between these two disciplines. This likely results from the categorization of the topics into two classes or two separate years of study. In this article, the author provides one example of how the two disciplines can be related in an environmental application that…

Woolverton, Christopher J.; Woolverton, Lyssa N. – American Biology Teacher, 2006
Toilet paper (TP) composition and physical characteristics were used to model scientific investigations that combined several "National Science Education Standards." Experiments with TP permitted the integration of TP history, societal change resulting from invention, mathematics (including geometry and statistics), germ theory, and personal…

Wassmer, Gary T.; Kipe-Nolt, Judith A.; Chayko, Catherine A. – American Biology Teacher, 2006
We present an effective, engaging, and fun method for teaching how the use or misuse of antibiotics can select for resistant strains of bacteria. This method uses candy as a substitute for strains of bacteria varying in resistance to a given antibiotic. Results and discussion are presented in the context of this emerging healthcare crisis.

Mott, John E. – American Biology Teacher, 1984
Examines heterologous expression in Escherichia coli and the role of regulatory sequences which control gene expression at transcription resulting in abundant production of messenger RNA and regulatory sequences in mRNA which promote efficient translation. Also examines the role of E. coli cells in stabilizing mRNA and protein that is…

Russo, A. J.; And Others – American Biology Teacher, 1984
Background information, list of required materials, and procedures are provided for an immunological assay which has been modified for use as a classroom/laboratory demonstration of antigen-antibody reaction. The assay is designed for a two and one-half hour laboratory period but may be modified for one hour laboratories. (JN)
