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…

Educational robotics activities are gaining in popularity. Though some research data suggest that educational robotics can be an effective approach in teaching mathematics, science, and engineering, research is needed to generate the best practices and strategies for designing these learning environments. Existing robotics activities typically do…

Here, we describe a laboratory experiment as part of an upper-level vertebrate physiology course for biology majors to investigate the physiological response of vertebrates to osmoregulatory challenges. The experiment involves measuring plasma osmolality and Na[superscript +] -K[superscript +] -ATPase activity in gill tissue of teleost fish…

The academic needs of gifted students are qualitatively different from those of regular students. This document describes a course that is differentiated for gifted students in the areas of content, process, learning environment, and product. Emphasis is placed on higher order thinking skills through independent study dealing with real world…

Describes the goals, procedures, and activities of a Computers in Chemistry course for undergraduate chemistry majors. Provides a listing of topics which have user-friendly programs and of representative activities which have been incorporated into the course. Also includes suggestions for student assignments. (ML)

Describes problems with teaching embryology in the traditional manner. Presents a new approach where students prepare presentations, questions, and discussion topics. During laboratory periods, students conducted their own long-term research projects. (PR)

An introductory Natural Science course with a focus on the laboratory is described. The main function of the course is getting students prepared for required individual projects in science. A copy of the syllabus, a description of laboratory experiments, and the context of the course are included. (KR)

The development of a spaceflight simulation program as part of a research and development course is described. Topics such as space exploration, design, propulsion, aerodynamics of space craft, robotics, communication, construction, medicine, lasers, hydroponics, geology, chemistry, and space physiology are emphasized. (KR)

Describes using the course question: "How does chemistry (or biology) impact my personal life and society?" This course question is presented to students and forms the basis of the final exam. Students evaluate a current-events article using the question as a framework. Students explore the relationship between chemistry (or biology) and their…

The National Council of Teachers of Mathematics, the National Science Teachers Association, and the American Association for the Advancement of Science present compelling arguments for teachers to make connections with other disciplines. This document describes integrated mathematics and science courses developed at North Georgia College. Appendix…

During a time when the values in society are changing, knowledge is rapidly expanding, technology is changing, and the use of science and technology is increasing, there is a need to review the role and nature of a biology program for the schools. Such a review was conducted by the K-12 Science Working Party of the Manitoba Department of…
