This booklet was designed as an aid for elementary and secondary school teachers. It is divided into two distinct parts. Part I is a brief tutorial which introduces some of the most important concepts about comets. Areas addressed include: the historical importance of Comet Halley; how comets are found and names; cometary orbits; what Comet Halley will look like; how and when this comet can be viewed; the nature of comets; and Comet Halley in 1910. Part II contains a number of suggested activities built around the comet. These include both classroom exercises and carefully described field work to observe the comet. Guidance is provided on where to look for the comet, how to observe it, and how to photograph it. Virtually every exercise can be done without special equipment; all that is needed is some thought on the part of the teacher to adapt the activities to the appropriate grade level. A list of selected readings is provided at the end of the booklet for those who desire a more in-depth treatment of the subject. (JN)
