Reports and discusses observations of three confident, experienced teachers organizing investigative science in their classrooms. The teachers wore microphones and the recorded data coupled with field notes formed a record of what happened that could be negotiated with the teachers. (DDR)

Describes an activity in which students make milk solids separate from the milk. Provides background information, a series of questions that students should be asked as they approach and perform the activity, and ideas for extension projects. (DDR)

Describes an earth science unit in which students study soil from their own backyards through a series of integrated activities. Introduces several earth science concepts, including local geology and the development of different types of geological regions. Presents activities to make a county soil map, measure moisture in soil, and measure the…

Describes activities using sensors connected to a computer via a data-logger. Elementary students investigated several scientific questions of sound, light, and temperature sensors including: What is the effect of putting a coat on a snowman? How can you make a hot drink cool down quickly? Do sound, light, and temperature vary in different…

Describes a science program called "Environmental Science on the Three Rivers" which coordinates hands-on water-ecology experiments for local schools on a modified Navy training vessel. The vessel holds 35 students and stops at three major sampling stations during a four-and-a-half-hour class. The program is conducted by people with…

Delineates four elements of successful student-scientist partnerships: (1) use of an inquiry-based approach; (2) employment of authentic, community-based investigations; (3) student in the role of scientist; and (4) student in the role educator. Contains 17 references. (DDR)

Describes the Earth Day-Forest Watch Program which introduces kindergarten through high school level students to field laboratory and satellite-data analysis methods for assessing the health of Eastern White Pine forest stands. (DDR)

Describes a South Carolina family-science program featuring nongraded recreational weekend programs conducted by experts at their facilities. The format allows in-depth presentation of topics using community resources, lets elementary students experience real applications of science and see scientists as role models, and strengthens parent/child…

Presents an excerpt from "Network Science, A Decade Later: The Internet and Classroom Learning", a publication based on four years of research that examines the role of technology in fostering inquiry-based approaches to learning. (Author/NB)

Argues that the life sciences offer potential for practical work to be undertaken outside the classroom. Explores a rationale for such work and draws on reported studies from a number of countries. Contains 44 references. (DDR)

Describes the Proffit Mountain project, part of a senior-level class in applied geophysics that provides students with hands-on experience in applying principles and techniques learned in class. Students conduct magnetic, gravity, and radiometric studies over a diabase body which intrudes rhyolite at Proffitt Mountain in southeast Missouri.…

Describes River Watch, an award-winning floating river study project that gives students continuous contact with the river environment. (PVD)

Presents a water-quality monitoring project in a Denver school that has evolved into an experiment using a constructed wetland system to treat the acid-mine drainage from an abandoned gold mine. (PVD)

Describes two science activities concerning water density and shares an idea for combining these activities into a third, completely new activity. Demonstrates the joy of rekindling the spirit of scientific thinking in a typical classroom. (PVD)

Reports on a case study that examines the beginnings of gender differentiation during a naturally occurring academic activity designed to support and guide young children's interest in doing science. Contains 25 references. (DDR)
