Describes chemistry laboratory experiments that can be done with student-designed investigations. Suggests approaches for restructuring traditional chemistry laboratories. (DKM)

Describes a series of hands-on experiments that engage students in hypothesis testing and promotes active learning of the concepts of evolution and adaptation. Laboratory exercises demonstrate how features of the hands and eyes distinguish primates from other mammals. (SOE)

Presents 12 points about experimentation all teachers concerned with evidence-based reading instruction should keep in mind as they evaluate assertions about literacy education. Reflects on how responsible experimenters who wish to inform literacy instruction should communicate research results to classroom practitioners. Concludes that educators…

Uses a university campus as the focus for a study of the entire watershed. Presents a context for incorporating pedagogical elements, interdisciplinary teaching, research experience, and active, collaborative strategies into a useful framework for undergraduate science education. (Author/KHR)

Introduces chemistry laboratories in which students have the opportunity to conduct laboratory projects in multiple sessions that promote planning, thinking, technical performance, and responsibility. Defines the process of experimentation and its applications to science laboratories and describes successful project applications. (YDS)

Examines the psychology of learning and its application to work in the laboratory. States that the working memory capacity of students is limited; therefore the amount of information they can process needs to be controlled and "recipe following" in the laboratory is perfectly reasonable. (RT)

Describes an inquiry activity in which students explore the variables that influence the amount of time it takes a ball to roll down an inclined plane. Relates features of the activity to recommendations in the NCTM Standards. (MKR)

Describes the activities of the kNights of Physics, a group of preservice teachers, whose goal is to spread the knowledge of the fun of physics to elementary students and their parents. (JRH)

Describes a system that demonstrates how a color may be generated and specified in mathematical terms. Illustrates the mixing of primary colors as well as the concepts of saturation, luminance, and illumination. (JRH)

In four experiments, college students acting as teachers to a simulated class of six students adopted a policy to balance achievement means and variances, allocating about 50 percent of the time to group instruction and the remainder to individual instruction. Results indicate that simulations can help teachers improve instructional decision…

Describes an experiment where students test the furcula or wishbone of a bird for its springlike properties. (PR)

Presents the general theory to explain chemical movement in soil. Describes classroom demonstrations with visually stimulating results that show the effects of soil structure, soil texture, soil pH, and soluble organic matter on that movement. (MDH)

Science fair mentorship programs let students investigate a wide variety of science topics under the guidance of interested community members. These programs enhance the relationships among school, community, and home. (PR)

Describes an Introduction to Chemical Engineering course with particular reference to the development, use, and evaluation of four simple experiments centered around the fundamental principles of heat transfer, mass transfer, reaction kinetics, and momentum transfer. (WRM)

Describes an early childhood educator's approach to teaching children about rain, rainbows, clouds, precipitation, the sun, air, and wind. Recommends ways to organize study topics and describes experiments that can help children better understand the different elements of weather. (MOK)
