Teaching Tools for Astronomy

A collection of educational materials to help explore the ways of the sun, the moon, and the stars.

This is a collection of printable teaching aids I developed while teaching astronomy to schoolchildren. The collection consists of PDF files that you can download, most of it containing printouts to be labeled, cut out, and used as the basis of some activity or other. Officially, I am making all of these works available under a Creative Commons--Attribution License, which means you may do anything you like with them, as long as you give me credit as the creator. If you find these materials valuable, I'd love it if you'd tell all your friends. I've been working on turning some of them into wooden or metal versions, which I hope to make available for sale, but those aren't ready yet. The astrolabe is a very old creation that I designed specifically for the latitude of our school. Updated versions for multiple latitudes are nearly ready.
