Free Worksheets: Gravity & Orbits for World Space Week
The Moon is falling right now. So is Earth. So is everything orbiting anything. That's not a typo, it's literally what an orbit is, something falling forever and just barely missing.
World Space Week runs October 4-10, and that's the kind of thing these worksheets get into. If your kid has already memorized the order of the planets a dozen times over, these go somewhere different, into the kind of concepts usually saved for high school, orbital mechanics, gravity as a force that actually varies planet to planet, why orbits aren't circles. None of it requires algebra to understand, and all of it is genuinely reachable well before high school.
Two versions, free, pick the one that fits.
Grades 1-3: Gravity as a pulling force, heavier-or-lighter comparisons between planets, true or false, fill-in-the-blank, and a draw-it activity.
Grades 4-8: Why orbits are ellipses instead of circles, why Jupiter's gravity would crush you even though it has no solid ground to stand on, and how a planet made almost entirely of gas, Saturn, somehow doesn't out-pull Earth. Diagram work, planet matching, and real think-it-through questions.
Grab whichever one fits your kid and go.
Looking for more this week? Two of my free async classes line up perfectly with Space Week:
The Real Science in Bradbury's All Summer in a Day (Venus's atmosphere, and why it's basically a pressure cooker).
The Martian Potato Problem (what it would actually take to grow food on Mars).
