The Thousand-Yard Model
or, The Earth as a Peppercorn

New edition 2012, amplified and with a variety of illustrations (including cartoons) — making this popular product even more attractive!

Instructions for using common objects such as nuts to make a solar-system model, over a distance of 1000 yards. It could be called a Model, Walk, or Happening. Tested many times with groups of children, who invariably are spellbound by the incredible distances. Since it also leads to a vivid grasp of light-years, star sizes, etc., it is an ideal opener to any astronomy course.

This description was twice printed in magazines, and was revised and reprinted as a booklet because there are so many requests for copies of it. The exercise has been performed annually or monthly by some astronomy clubs and at the American Museum of Natural History, New York; has been proposed as an installation in the city of Portland, Oregon; and we know of it being done in Peru, Guadeloupe, Iceland, Japan, and along a kilometer of the Great Wall of China.

8.5 x 9.5 in., 26 pages, color painting on cover, illustrations; cartoons by Ian Dicks. 1989; 5th printing with revisions 2004; 2nd edition 2012. ISBN 978-0-934546-21-8.
