Describes an integrated unit on bluebirds that culminates in students building bluebird boxes and creating an informational pamphlet to raise public awareness of the bluebirds' plight. Enables students to become more involved in their community and the environment. (JRH)

Presents an activity that reinforces concepts about plant and animal cells. Also gives students the opportunity to see how a battery works and how a series circuit operates. Allows students to be creative and makes them more receptive to learning about electricity. (JRH)

Describes a study that included classroom lessons on hydroelectric power, the history and construction of a nearby lake, data recording, the use of field guides, and methods of counting natural populations. The study culminated in a field trip to the lake. (JRH)

Presents a strategy that helps students visualize and comprehend moon phase changes through activities that use an Earth-centered point of view along with direct observations of the moon. Describes activities that parents can use at home to help children become familiar with observing moon phases. (JRH)

Describes an activity designed to give students practice in generating, analyzing, and interpreting class data to create a concrete representation of relative mass and atomic mass unit. The activity uses rice, corn, and beans and employs a historical approach to engage students. (DDR)

Describes a "Synthesis and Reactivity" curriculum that focuses on the correlation of laboratory experiments with lecture topics and the extension of laboratory exercises beyond the usual four-hour period. Highlights experiments developed and an out-of-class computational chemistry exercise using CAChe, a versatile molecular modeling…

Describes an inservice professional development program, Project LIFE (Laboratory Investigations and Field Experiences), that has successfully implemented guidelines from the National Science Education Standards. Includes a three-week summer course; an independent science research project; academic year follow-up through workshops, classroom…

Describes an activity in which students apply the scientific method as they explore each step of crystal growing. Students select variables, record daily observations, and participate in discussions about the differences in crystal formation. Crystal recipe and procedures are provided. (DDR)

Describes a strategy that combines a field trip to a pond with technology such as digital cameras and educational software to help children expand their knowledge about ponds. Involves students sharing this new knowledge using computer writing and drawing tools. Lists science software resources and writing/drawing programs. (JRH)

Describes an experiment in the teaching of introductory general physics at the college and university level that focuses on self-directed learning. Discusses the "Standard Model", premises of self-directed learning, classroom implementation, class work, laboratory work, out-of-class work, and assessment. Contains 34 references. (JRH)

Describes an alternative method for exploding hydrogen balloons as a classroom demonstration. Uses the method of igniting the balloons via an electronic match. Includes necessary materials to conduct the demonstration and discusses potential hazards. (SOE)

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)

Explores the results of a study that involved qualitative analysis of students' reactions to a long-term inquiry experience in a freshman biology course. (DDR)

Introduces a science activity on butterflies and their life cycles in which students keep journals of their observations. Explains how to build a butterfly observatory in the classroom. (YDS)

Details the use of tabletop models that demonstrate concepts in direct current electrical resistivity, self-potential, and electromagnetic geophysical models. Explains how data profiles of the models are obtained. (DDR)
