Honeybees provide a convenient source of insect flight muscle, a tissue especially rich in mitochondria. These organelles are easily isolated using simple laboratory equipment and their metabolic activity readily measured colorimetrically with the dye 2,6-dichloroindophenol, which changes from blue to colorless when reduced by the electrons produced during respiration. This system is well-suited for studying cell fractionation, experimental isolation of the major subcellular components responsible for glycolysis and the Krebs cycle, and the role of oxygen in respiration. It can also be used for simple enzymology experiments using the Krebs cycle enzyme succinic dehydrogenase. (less)

This course covers specialized and somewhat advanced topics in the fields of cellular biology, molecular biology, biochemistry, and genetics. It does not cover organismal biology or taxonomy. The course is carefully planned to provide the background that biology students will need for advanced biology classes. Non-biology majors will also find this course useful as it explains many of the concepts and techniques currently discussed in the popular press. This course is built around six key concepts that provide unifying explanations for how and why structures are formed and processes occur throughout your study of biology. Because it is not possible to cover the breadth of modern molecular biology in one semester, an understanding of these key concepts will provide a basis for extension of your knowledge to biological systems beyond the specifics covered in this course. One of the major goals of the course therefore is for you to not only learn the definitions of the concepts but also learn to recognize when they are operating the process being studied. Topics covered include: Biological Chemistry, Cell Biology, Molecular biology, and Metabolism. (less)

This is a companion website to a NOVA television series investigating strange life-forms found in toxic caverns. The program reviews the traditional theory of cave formation; introduces new theories of microbial sulfuric acid production; examines the role of oil-feeding microbes in dissolving limestone; presents the discovery of microbes in caves that live solely on chemical nutrients; and reviews other extreme environments. The site offers an interview with a microbiologist, an essay by a caver, a slide show of decorated caves, a teacher's guide including the classroom activity entitled "Microbial Townhouse," and interactive animation about cave formation.

This workshop demonstrates on-line use of the national electronic bulletin board, complete with electronic mail started in 1987 by the National Association of Biology Teachers. Once on-line, 14 special interest areas are available, such as AP- Biology, magazine and book reviews, ABT Journal, NABT membership services, question and answer forum, software reviews, and swap/sale of used equipment. Also available for downloading onto your computer are extensive files of labs, graphics, and handouts. Discussions of this and other databases will emphasize the power of these new professional communication tools.

This protocol represents a cost-effective modification of the Ames Test that allows students to investigate the mutagenic potential of various common substances. Potential mutagens are tested using well-characterized auxotrophic strains of Salmonella typhimurium. By analyzing the results, students determine if any of their compounds may be mutagenic. Follow-up experiments are designed to determine the dose response of these potential mutagens. Using this protocol, we have achieved reproducible results with several known mutagens, including sodium azide and ultraviolet irradiation. This approach enables faculty to control costs and results to improve student understanding of mutagenesis, biochemical pathways, experimental design, and data analysis. (less)

Astrobiology in the Classroom leads students in the exploration of the limits of life on Earth to extend their beliefs about life to include its possibility on other worlds. In this four-part activity, students first explore the environments of several mammals and birds to better understand how living things and their environments interact and depend on each other. In the second part, students match bacterial types with their more extreme environments. Students discover that an environment's temperature, salinity, pH, and sources of carbon and energy are important for what can live there. Next, students are given readings on life in extreme environments that cover the latest scientific findings in this field and are asked to answer reflective-questions. With their new understanding of the limits of life on Earth, the final part guides students in the exploration of environments on other planets and moons in our Solar System. Word is required for opening this document. (less)

In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity. Learners will calculate how many Calories a typical teenager needs every day, known as Basal Metabolic Rate or BMR, as well as their own baseline Calorie needs based on gender, age, height, and weight. Learners will calculate this using the Harris-Benedict Equation. This guide includes background information, setup and management tips, extensions, and handouts. (less)
