Contains information on rain sticks and other similar musical instruments. Describes procedures for making rain sticks and using them in the study of sound. Discusses the physics of sound and how to utilize computers to study sound with rain sticks. (DDR)

Whether boys and girls shared equally in performing behaviors required in hands-on activities in the performance-based science classroom was studied over the school year with 165 students in grades five through eight. Being actively involved predicted students' year-end science attitudes, and boys tended to handle the resources more often. (SLD)

Investigates how museum visits can be used to meet the goals of practical work. Introduces a framework to facilitate student learning in museums. Contains 31 references. (DDR)

Presents an exercise in which cutouts or outlines of dinosaur footprints placed independently or in sets on the floor and laboratory benches are used to model dinosaur trackways. The nature, size, speed, and specific behavior of the trackmaker are determined from the trackways and from student-derived data as well as from diagrams and models based…

Frogwatch is a volunteer monitoring program developed in response to worldwide concern about declining populations of amphibians. Outlines a frog-monitoring program and a wetland study to be conducted alone or together. Explains the basics, including choosing a frog, introducing the topic, mapping, recordkeeping, equipment, survey procedures, and…

Designates Frank Halliwell as an inspiring science teacher who employed the demonstration lecture method very effectively. Traces the origin and development of this method to John Tyndall and provides numerous examples of his work. (DDR)

Explains the development of an interdisciplinary unit in which students learn basic chemistry and laboratory techniques while practicing English, mathematics, art, social studies, and leadership skills. Includes details about lab activities, assessment strategies, and science extensions. (DDR)

Details an activity in which students are challenged to consider real-world problems. Students collect and organize data on two fish species, examine the data mathematically, draw conclusions about the organisms with which they work, and extrapolate the results to other environments. (DDR)

To experience the world of professional science, students must have access to the scientific community and be allowed to become real scientists. A partnership involving the National Aeronautics and Space Administration, the Jet Propulsion Laboratory, and the Lewis Center for Educational Research has produced Jupiter Quest, an engaging curriculum…

Discusses reasons why inservice workshops often fail to impact science teaching. Describes restructuring of a workshop series so that teachers become real science learners, struggling with their own ideas about different scientific concepts as they design experiments and share theories with their peers. (JRH)

Outlines the evolution of environmental education in Russia, based on authors' experiences in transforming curricula in the Republic of Bashkortostan. Summarizes changes adopted in the secondary school and in three regional universities. Evaluates specific problems of introducing environmental education at the pedagogical and engineering oriented…

Discusses the categories of spatial thinking and explains methods for helping students develop spatial thinking skills, ask open-ended questions, and choose student-centered activities. Provides activity examples that involve spatial thinking for elementary grades. (YDS)

Describes the famous swing bridge in Belize. Students build bridges from a variety of materials and answer the questions, What are different types of bridges?, How do bridges work?, How can you tell if a bridge design will be safe?, and What is the best way to build a bridge over a river while still allowing boat traffic? (SAH)

Describes historical precedents and current trends in the incorporation of gardening into the school curriculum in South Carolina and California. In these outdoor classrooms, children plan and implement specific projects related to nutrition, environmental awareness, and community beautification, as well as an appreciation for nature. (SAS)

Reports on a student's research project on the degree of genetic diversity within the trout lily species. Enables a rough prediction of the continuance of the species and provides insight into how to manage plants that might be endangered. Contains 16 references. (DDR)
