Two computer-generated star charts that can be used as overlay transparencies to show an expanding universe are presented. Directions on how to use the star charts to determine the Hubble constant and the age of the universe are provided. (KR)

Describes the organizational framework, didactic and methodological considerations, and the content of a four-day astronomy project in a secondary West German school. Presents information on the media used and related literature. Appended are the instruments of observation. (DB)

Describes some of what a science teacher learned while participating in an amateur observing program that provided access to the Hubble Space Telescope. (ZWH)

Describes types of meteors and micrometeorites that enter the Earth's atmosphere. Presents an activity where students collect micrometeorites with a strip of tape in an undisturbed outdoor area. After 24 hours, they examine the tape by sandwiching it between 2 glass slides and view through a microscope at 100X. (PR)

Presents activities to stimulate the curiosity of grade 10-12 students and introduce them to astronomical observations. Exposes students to the evolutionary theory of stars and the structure of the universe. (DDR)

Contends that storytelling is a device which physics teachers can add to their repertoire for motivating and encouraging students. Presents an example of effective storytelling using the story of the COBE discovery of ripples in cosmic background radiation. (Author/WRM)

Examines third-grade students' ideas on the lunar phases prior to, and following, an instructional period designed to promote students' conceptual change. Demonstrates that students are capable of making conceptual changes. Contains 30 references. (DDR)

Describes a way to demonstrate the causes of seasons and related phenomena by using an umbrella and flashlight. (WRM)

Explains how to create a paper replica of the Bighorn Medicine Wheel, an ancient timepiece thought to have been constructed by the Lakota Indians around 1700 A.D. The Bighorn Wheel uses four key seasonal stars as well as the solstice sunrise and sunset to mark the passage of time through the summer. (WRM)

Outlines a way for instructors to teach astronomy and the nature of scientific inquiry. Highlights a discussion with students during coverage of the Earth-Moon system. (CCM)

Describes a procedure that allows undergraduate students to determine the approximate age of the universe using their own data. The experiment requires a relatively small telescope with a modest spectrograph. Includes sample data and calculations. (Contains 11 references.) (Author/WRM)

Explains how solar eclipses occur and provides information on future eclipse events. Also includes a solar eclipse viewing activity. (DDR)

A longitudinal study of the influence of education on children's ability to define and explain astronomical concepts was conducted with 20 students aged 10 and 11. At 2 months after the lessons, students recalled the explanations they were taught, but 4 years later they provided only everyday and inaccurate explanations. (SLD)

Discusses teaching ethnoscience in the classroom. Presents an activity incorporating an ethnoscience example, Mayan Ethnoastronomy, in the science curriculum. (Contains 12 references.) (ASK)

Reports and analyzes the day and night cycle, the seasons, and the phases of the moon as seen by Norwegian deaf pupils aged 7, 9, 11, and 17 years, and by hearing Norwegian pupils 9 years old. Among the 9-year-olds there was no difference in the inner coherence of the conceptions between deaf pupils. (Author/SAH)
