Presents five plant science stories and examines the real truth behind them. (Contains 28 references.) (ASK)

Discusses the use of small enclosures for experiments in a local lake. Describes the effects of lake inhabitants grazing on small zooplankton such as Daphnia, copepods, and rotifers. (ASK)

Presents a quick and easy demonstration of species-area relationships. Focuses on common cynipid rose galls which can be found over much of North America. (ASK)

Describes a laboratory experiment in which students explore how a microbe makes cellulose. (ASK)

Presents an experiment that teaches the evolutionary approach to the study of animal behavior. (ASK)

Provides an exercise to promote students' understanding of the commonality of certain basic questions to all of biology and demonstrate the power of using different approaches with very different assumptions. (Contains 15 references.) (ASK)

Reaction stoichiometry calculations have always been difficult for students. Offers the use of a mole ratio flow chart (MRFC) as a logistical sequence of steps that incorporates molar proportions as alternative problem solving techniques to improve student understanding. Indicates that MRFC users performed as well on exam problems covering…

Describes the mentoring relationship between George Washington Carver and Henry Agard Wallace who later became a great scientist and Vice President of the United States. Explains what mentoring is and discusses classroom implications for mentoring. (PR)

Presents scientific and technical information related amateur radio operation, commonly called "ham" radios, and radio astronomy. (PR)

Presents a laboratory experiment showing the properties of smooth muscle using the crop and gizzard of the earthworm. (ASK)

This study investigated the effects of peer collaboration and discourse patterns on conceptual change in the context of high school students learning from incompatible scientific information. Findings suggest that peer effects may vary depending on collaborative interactions and that students need help to engage in productive discourse. (Contains…

Changes in the concepts of kingdoms of organisms are substantial and Protozoa is loosely characterized. Presents a case explaining how Protozoa interface with other kingdoms of organisms now recognized. (Contains 55 references.) (ASK)

Presents an activity that is suitable for a high school chemistry or introductory college chemistry lab in which students create their own Fizzie-style carbonated beverage and use stoichiometry to calculate the correct mix of citric acid and baking soda. (Author/ASK)

Teaching Earth science without exposure to rock outcrops limits students depth of understanding of Earth's processes, limits the concept of scale from their spatial visualization imaging, and distorts their perception of geologic time (Totten 2003). Through a grant funded by the National Science Foundation, an artificial rock outcrop was…

Thinking about macroscopic phenomena in terms of models based on the idea of microscopic particles (i.e., the particulate theory of matter) is one of the important goals for student learning in chemistry around the world. However, previous research suggests that students do not easily understand phenomena from a particle perspective, although such…
