Ditch your watch and use the sun to tell time

This is a really cool project for older kids. I’d love to try it with Cedar, but he’s still little enough that he measures everything in “Spongbob episode” time. Time makes him fuzzy.

Make your own sundial: 

Nasa offers one of the better make your own paper sundial pages I’ve seen.  Not only do they offer full instructions for both an easier paper sundial and a more sturdy version, but they include complete explanations behind how and why a sundial works. Information on accuracy, history, latitude, and further resources are all covered.

This is just one more cool way we can use the power of the sun.
