Describes a science activity in which students study stream profiles of an imaginary aquatic environment, measure the stream depth, and graph the cross section both in classroom simulations and on a field trip. (YDS)

Describes a sea-water analysis project that introduces qualitative and quantitative analysis methods and laboratory methods such as gravimetric analysis, potentiometric titration, ion-selective electrodes, and the use of calibration curves. Uses a problem-based cooperative teaching approach. (Contains 24 references.) (YDS)

Describes portable scientific laboratories that allow students to go beyond the classroom to do field work. Presents examples of a curriculum that incorporates portable technology and discusses its advantages in inquiry-based science programs. Includes handheld probes and peripherals. (KHR)

Points out the importance of socioscientific aspects of laboratory activities for the development of understanding of different cultures' contributions to science. Describes a lesson on gene splicing using the 5E Learning Model. (YDS)

Describes classroom-developed science and mathematics backpacks, self-contained educational packets developed around a theme or concept and designed to be completed at home. Presents generalized contents, a sample backpack on colors, and the backpack's advantages, including promotion of active learning, family involvement, curriculum integration,…

Unit of study about rocks and the layers of the Earth focuses on building children's respect for nature by developing feelings of intimate relationship. Lesson plans include science activities (rock gathering, Earth models); "drama from the outside" (ritual to promote respect); literature readings; and "dramas from the inside"…

Addresses the use of computer simulation games and how they can be tailored to fit particular units of study in secondary science education. Focuses on scripted role play simulations and specific purpose simulations. (DDR)

Presents a range of exciting ideas for encouraging active learning, for illuminating new concepts, and for making science lessons fun. Topics include modeling, matter, heat, diffusion, changes of state, heat transfer, energy changes, atomic structure, waves, gravity, enzymes, and habitats. (JRH)

Presents a rationale for including experiences that draw profound reactions of pleasure or revulsion in the science classroom. Provides some suggestions for using them effectively. Discusses content knowledge, process skills, language development, scientific attitudes, tips for using novel experiences, and marveling at mysteries. (JRH)

Investigates students' ideas about gravity beyond the earth's surface. Presents a lesson plan designed to help students understand that gravity can act beyond Earth's atmosphere. Also helps students gain a more adequate intuitive understanding of how natural and artificial satellites stay in orbit. Reports that this strategy changed some students'…

Describes an activity designed to teach students geology vocabulary while challenging them to solve the case of the missing marble. Can be adapted to teach vocabulary for different topics. (JRH)

Details a program sponsored by the Potomac Region Solar Energy Association (PREA) that provides local high school students with access to photovoltaic kits and encourages them to learn more about photovoltaics through a design competition. The purpose of this article is to inspire groups in other communities to initiate similar projects. (DDR)

Reports the results of a survey that assesses the breadth of implementation of environmental education in local public schools, the integration of environmental education within the existing school curriculum, and the impact environmental education has had on the school. (DDR)

Presents an activity in which students investigate the chemistry behind color-changing markers. Includes the objectives, materials, procedures, and follow-up for the activities. (DDR)

Presents an activity that demonstrates how a traditional activity can generate questions not typically raised in a conventional course. In the context of astrobiology, students can connect to an intriguing endeavor, the search for extraterrestrial life. (DDR)
