Presents pendulum lab results as an example for students on the write-up of experiments. (PR)

Describes a program where high school students developed a science presentation consisting of 10 demonstrations on wave motion. It is noted that the presentation was highly sought after by other schools. (MVL)

Provides an introduction to Project WET (Water Education for Teachers). Examines approaches to water education, how the Project WET program is different from other water education projects, how the program is implemented in the classroom, what kinds of materials are available, and how to obtain Project WET. (LZ)

Describes activities that take advantage of heavy snowfalls to study numerous geological concepts including sedimentation, precipitation, morphology and metamorphosis of crystals, compaction and cementation, fossilization, and erosion. (JRH)

Presents a small sample of the lesson plans developed as a result of a summer workshop that allowed a high school physics teacher to explore the uses of satellite-derived sea surface temperature fields in the physical science classroom. (ZWH)

Discusses the use of 40 kHz ultrasonic transducers to study wave phenomena. Determines that the resulting wavelength of 9 mm allows acoustic experiments to be performed on a tabletop. Includes transducer characteristics and activities on speed of sound, reflection, double- and single-slit diffraction, standing waves, acoustical zone plate, and…

Describes a method for capturing a real object and its real image on film. Explains many photography terms related to the experiment. (MVL)

Combines the PASCO Free Fall Adapter with a homemade timing sensor. Provides hints for successful operation of the timer and the Atwood Machine. (MVL)

Discusses activities to investigate rock art in science courses. (MKR)

Perceived risk is a function of information, knowledge, values, and perception. This exercise is designed to illustrate that in many situations there is no correct answer, only best-alternative choices. The exercise has five parts in which students work in groups of five. (LZ)

Describes a constructivist approach to teaching a second-grade science unit focusing on the moon, using student observations and data collection. Lays the foundation for the evolving development of conceptual understandings of earth, moon, and sun interrelationships in other grades throughout the school. (nine references) (JRH)

Presents an experiment to demonstrate the diurnal and seasonal motions of the sun, which can be used in different grade levels, depending on the degree of difficulty required for the analysis, as an effort to generate student interest in the scientific method. Includes an activity to teach students elementary concepts of the sun's apparent motion…

Presents an exploratory experience that allows students an opportunity to practice science process skills and use all of their senses. Describes a fruit study activity, appropriate for grades three through six, that incorporates the learning cycle (exploration, concept development, and concept application) and cooperative learning strategies.…

Kinesthetic apparatus make physics learning experiences stimulating, memorable, and influential in helping students relate natural phenomena to the laws of physics. Describes a number of experiments and demonstrations that are possible with kinesthetic apparatus, which help eradicate some traditional student misconceptions and provide students…

Describes a soap-solution activity involving formation of bubbles encasing the students that requires only readily available materials and can be adapted easily for use with various grade levels. Discusses student learning outcomes including qualitative and quantitative observations and the concept of surface tension. (JRH)
