Children should learn early that science is about doing, about experimentation, and not about recalling facts. This article suggests science curriculum ideas that emphasize process and discovery. A sample lesson plan employing the scientific method is given as well as a resource list that contains suggested sources for experiments. (IAH)

Prescriptions for improving student understanding and problem-solving performance related to transmission genetics are discussed. Research on novice/expert problem-solving in transmission genetics is reviewed. (Author/CW)

Discusses how a spreadsheet might be used in an introductory physics laboratory. Describes three categories of spreadsheet uses, advantages of spreadsheet, layout, accuracy, and modifications. Gives an example of the variable mass rocket problem with typical display. (YP)

Introduces a method for two-dimensional kinematics measurements by hanging marbles with long strings. Describes experimental procedures for conservation of momentum and obtaining the coefficient of restitution. Provides diagrams and mathematical expressions for the activities. (YP)

Provides a poster which focuses on how electricity is made, distributed, and used by the community. Includes a vocabulary list with definitions, additional information, and illustrations on topics such as thermoelectricity, static electricity, and electric current. (RT)

Examines the educational value of exhibits for transferring wildlife information to high school students. Reports that the passive exhibitry technique produced increases in the wildlife knowledge of students. (Author/YP)

Describes an exercise in which students use a hydrological instrument in an actual field situation to measure stream discharge. (RT)

Determines how the use of a science education program affected selected ninth-grade students' comprehension of science reading material. The different effects of the program depended on students' reading and mathematics scores. (Author/YP)

Demonstrates the inverted image, the chromatic aberration, and the floaters of the eye using an opaque 35mm film container with a small pinhole poked through the bottom. Describes the observation of Haidinger's brushes using polarized light. (YP)

Described is a curriculum project developed in Germany. The importance of playing and gaming for the acquisition of cognitive and social capacities, the relationships among acting, reasoning, and learning in physics instruction, and the spheres of subjective experience are discussed. The framework and evaluation of the curriculum are outlined. (YP)

Discusses a demonstration of interference phenomena using three sheets of polaroid material, a light source, and a light meter. Describes instructional procedures with mathematical expressions and a diagram. (YP)

Errors in the teaching of the concepts of Charles's Law are traced back through history to a major French physics text published in 1816. Relevant original sources are quoted and remedies are suggested. Five major criticisms are summarized. (Author/CW)

Outlines a suggested scheme for introducing young children to the subject of classification by using pets and an investigatory approach. General objectives and introductory, developmental and culminating activities are provided. (Author/CW)

Describes an air track experiment demonstrating the transfer of mechanical energy from elastic potential to kinetic. Discusses four methods for calculating energy stored in the spring. Included are pictures, typical data, and graphs. (YP)

Describes an exercise in which students convert lithostratigraphic columns into chronostratigraphic columns, infer paleolatitude using paleomagnetic data, interpret depositional environments, determine the timing of deformation and terrane collision, construct models, and synthesize the results into a geologic history. Background data, procedures,…
