To Catch A Comet...Learning From Halley's.
National Aeronautics and Space Administration, Washington, DC.
Comet chronicles and stories extend back over thousands of years. A common theme has been that comets are a major cause of catastrophe and tragedy here on earth. In addition, both Aristotle and Ptolemy believed that comets were phenomena within the earth's atmosphere, and it wasn't until the 16th century, when Danish astronomer Tycho Brache carried out his research, that comets were found to reside well beyond the orbit of the moon. More than a century later British scientist Edmund Halley placed comets even further out in space by calculating the orbits of a number of them. He also noted that certain comets had been observed to appear in the same orbital patterns three times at regular 75- to 76-year intervals and proposed that the explanation was that these were not three, but one comet--the comet that was later to be named Halley's comet in his honor. Although Comet Halley has receded into the outer solar system, it still regularly reappears and may still generate excitement for students. It is, in effect, a time capsule, binding grandchildren with grandparents, and scientists in one era with scientists of another. This booklet provides teachers with information essential to the study of Halley's comet when this topic is integrated into existing lessons plans. Because this booklet is designed as a teaching supplement for the classroom, the instructional materials are intended for use in the order presented. The first section includes the following chapters: (1) The Ultimate Time Travelers; (2) Touching Humanity; (3) Halley's History; (4) Where Do Comets Come From; (5) What is a Comet; (6) The Halley Fleet; (7) Through the Halls of Time; (8) Other Heavenly Wayfarers; and (9) Touching the Future. Section 2, which includes 43 classroom activities, is presented as a supplement to the first section. Vocabularies listed in section 2 are taken directly from the background information presented in section 1. The classroom activities are suggested for inclusion within a broad course of study or as isolated exercises, and are not labeled by discipline, grade, or ability level. The individual teacher's creativity and ingenuity can facilitate their application to almost any area of study. (KR)
