Free Solar System Word Searches for the Space Topic (Printable PDF + Answer Keys)

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.
