Human Body Crossword Puzzle | Free Printable Worksheet

A tour of the human body for upper-elementary scientists: the organs that keep us alive, the bones and muscles that move us, and the senses that tell us about the world. Each clue names what a body part does, so students have to connect the word to its job. Ready to print for a body systems unit, a science center, or a review day — no prep beyond hitting print.

Swap this list for whatever body system your class is studying right now — digestion, circulation, or just the skeleton — the same approach works for any science word set. For older students, swap the plain-language clues for textbook definitions. Paste the whole list in at once with the bulk-paste option, or add clues one at a time. Print one copy per student with answers hidden, then flip on Show answers and print a second copy for yourself as an answer key. No login, no student accounts, and nothing about your class gets collected or stored.
