Presents a student simulation activity based on the dideoxy chain termination method of determining the nucleotide sequence of DNA fragments developed in 1977 by Fred Sanger. (JRH)

Suggested are activities using a Polaroid camera to illustrate the capabilities of remote sensing. Reading materials from the National Aeronautics and Space Administration (NASA) are suggested. Methods for (1) finding a camera's focal length, (2) calculating ground dimension photograph simulation, and (3) limiting size using film resolution are…

Describes activities that allow students to work cooperatively to analyze and study evidence from crime scenes and archaeological digs. The activities demonstrate to students the interdependence of a variety of disciplines in the real world. (ZWH)

Describes an environmental simulation exercise conducted at an outdoor camp in Colorado. The two simulations involved the physical, social, political and environmental factors which might influence construction of an airport in the Rocky Mountain National Park and factors associated with a nuclear generating plant. (BR)

Presents a predator-prey simulation which involves students in collecting data, solving problems, and making predictions on the evolution of prey populations. Provides directives on how to perform the chi-square test and also includes an Applesoft BASK program that performs the calculations. (ML)

Presents a nuclear power plant simulation game which is designed to involve a class of 30 junior or senior high school students. Scientific, ecological, and social issues covered in the game are also presented. (HM)

Argues the pros, cons, and alternatives to animal dissection. Discusses several cases involving student objections and the enactment of a California state law which upholds the right of a student to conscientious objection to dissection involving the harmful or destructive use of animals. (RT)

An apparatus simulating residential thermostat control was developed to test claim that lowering house thermostats saves energy and to give students a better understanding of how thermostats work. The apparatus (includes diagram of same) and student activity are described. (JN)

Describes ways that computer-assisted instruction (CAI) is used in a high school biology course, including: (1) mastery of specific objectives; (2) CAI as a self-check; (3) computer games; (4) laboratory simulations; (5) genetics instruction; (6) writing programs; and (7) remedial assistance and testing. (CS)

Presents a simulation activity that allow students to work through the exercise of DNA profiling and to grapple with some analytical and ethical questions involving a couple arranging with a surrogate mother to have a baby. Can be used to teach the principles of restriction enzyme digestion, gel electrophoresis, and probe hybridization. (MDH)

Presents a simple activity that simulates natural selection working on random mutations through many generations. (PR)

Suggests cooperative learning projects if only one microcomputer is available for a large class. An example of such a project using a program dealing with correlating sedimentary rock layers through cross-sectional analysis is described. Instructional strategies and academic objectives of the three-module program are included. (JN)

Describes an activity to simulate the geometries of a spreading pathogen such as HIV throughout a generation. Students exchange "bodily fluids" three times and are then tested for the presence of "infection." Materials used include base solutions (NaOH or KOH), phenolphthalein (pH indicator), clear plastic cups, and an eye dropper. (PR)

Presents a general step-by-step description of how classroom games for science can be developed. Examples from the slim chance game from the Health Activities Project of the University of California at Berkeley are included. (HM)

Several types of physics activities that use real-world problems to motivate learners, use computers to assist in developing conceptual understandings, connect problem situations to mathematical models, and use the models to analyze other real-world problems are presented. The topics of racing sports, sailing, and damped harmonic oscillations are…
