Dear Learners,

We’re investigating the relationship between Earth and the sun, but because those things are so massive and so far apart from each other, we do it by observing something much simpler, smaller, and closer to home: our shadows.

And that shadow that you’ve been dragging around with you your whole life has a lot to tell us about how the solar system works. Yet you’ve probably taken it for granted or never even noticed it.

Knowledge is everywhere; everything is ripe for study. And no matter what you study, if you look closely enough, it will reveal something true and important about the bigger world.

Sincerely,

Mr. Heimbuck
