Buy Astronomy For Thinkers a coffee


I create resources for science education, with a current focus on astronomy.

I taught science to elementary and middle school students for many years. Along the way, I wrote a great deal of my own material, and designed and developed numerous teaching aids, all with the aim of making science education more about coaching, and less about dogmatic assertion. Now I am attempting to organize, prettify, and publish my best stuff.

In the field of astronomy, I created a number of sundials, compass roses, astrolabes, planispheres, and other makable projects of various kinds. Most of my designs started out as paper handouts, and I make many of these paper creations freely available for kids, parents, and educators on my astronomy website. I am also trying to turn some of these designs into wooden or metal items.

I also run an informal but more general science blog on which I list a few science projects I've tried.
