Describes a lab activity in which yeast is used as a model system for human digestion. Uses Smith fermentation tubes to measure carbon dioxide released from fermentation. (Author/KHR)

Students make connections in their social lives and expect teachers to do the same at school. Advocates connecting physics and biology in teaching as they are connecting more in research. Discusses some physics-based techniques used in biology and medicine. (YDS)

Presents an activity called "The Hardy-Weinberg Equilibrium, Founder Effect, and Evolution" to allow students to learn about evolution in an engaging, constructivist manner. The activity also uses the tools of mathematics to learn several related biology concepts. (Author/SOE)

Describes a unit to study the cycling of matter and energy through speleology using cooperative learning groups. Integrates the topic with zoology, biogeochemistry, paleontology, and meteorology. Includes a sample rubric for a salt block cave presentation, unit outline, and processes for studying matter and energy processes in caves. (Author/KHR)

Discusses the use of epidemiology as an introduction to useful aspects of biology, mathematics, and simulation skills for kindergarten through university undergraduate students. (Contains 20 references.) (ASK)

Presents an exchange of the views of six professional educators on the place of reading in science instruction. (AEA)

Describes an activity which connects mathematics and science by using data analysis and studies of animal camouflage. Includes a reproducible student worksheet to be used for data collection. (11 references) (MKR)

Describes an activity that demonstrates catalysis of chemical reactions by ultraviolet (UV) light using one of the earliest photographic processes, the cyanotype process. (CCM)

Describes a teaching tool that helps students understand that science is not a fixed body of knowledge but a continuous, dynamic process of human searching for answers often over a very long period of time. Using historical vignettes (short stories), teachers can help students make connections between the past and the present. (ZWH)

Describes a program designed to make physics more accessible to students. Entails extracting articles from newspapers (compiled to form a journal named "Exaktueel") and using them as a source of ideas for classroom activities. (ZWH)

Describes activities designed to give summer school students an appreciation of the value of an integrated approach to scientific investigation. (JRH)

Presents an activity that integrates mathematics and science and focuses on estimation, percent, proportionality, ratio, interconverting units, deriving algorithms mathematically, energy transformation, interactions of energy and matter, bioavailability, composition, density, inferring, and data gathering through scientific interpretation.…

Suggests activities that could be incorporated into a study and actual viewing of a total solar eclipse, including student involvement in real research projects. Lists related websites. (Author/WRM)

Explains how the muscle and bone arrangement of the human body can be used in teaching the principles of simple machines. Presents an activity that investigates the lever system of the forearm. Includes background information on levers and suggests questions for classroom discussion. (ML)
