Download and print free solar system word searches — a puzzle for each part of the space topic, from the planets and the Sun to the phases of the Moon, constellations, comets and the astronauts who went there. Every puzzle is a free PDF with the answer key included, sized for standard printer paper and ready for a science lesson, a space week or a rainy afternoon.
Each grid is built from its own subject rather than one generic space word list. The Moon puzzle runs the phases. The asteroids puzzle separates meteors from comets. There are grids for Mars and Jupiter on their own, for the International Space Station and the James Webb telescope, and an easier one made for younger children.
For the Space Topic at School
Space is taught in primary and middle school almost everywhere, usually across a few weeks covering the planets, the Sun and Moon, and space exploration. These puzzles follow that shape, so a class can take a different grid each lesson. For the wider subject there are companion hubs for biology and chemistry, plus the full space collection and a broader science collection.
What’s in Every Puzzle
Each download is a two-page PDF: the puzzle grid on page one, the completed answer key on page two. Fifteen words per grid, hidden in every direction. Nothing to sign up for and nothing to install — click a card, print the page.
How to Use These Solar System Word Searches
Print a set at the start of a space topic and hand one out per lesson, or use them as an early-finisher activity. They also work well before a planetarium visit — the planets, constellations and Moon phases grids cover most of what a child will see in the show. The Space for Kids grid suits solvers from about six; astronomy and the James Webb telescope will stretch older students.
