Can you spot HYDROCHLORIC, AMMONIA and INDICATOR?
PDF + answer keyScienceFree PDFs + answer keys
Download and print free chemistry word searches โ a puzzle for each part of the subject, from the periodic table and atomic structure to bonding, reactions, acids and bases, and the equipment on the bench in front of you. Every puzzle is a free PDF with the answer key included, sized for standard printer paper and ready for a starter, a revision session or a cover lesson.
Each grid is built from its own topic rather than a general science word list. The bonding puzzle hides COVALENT and OCTETRULE. The lab equipment puzzle hides the BUNSENBURNER and the BURETTE. The organic puzzle runs the alkanes and hides DISTILLATION and CRACKING. The vocabulary is the vocabulary a student actually meets in that unit.
For a puzzle built entirely from the periodic table, see the chemical elements word search, a free 15-word printable with its own answer key.

PDF + answer keyThe order follows how chemistry is usually taught: elements and the periodic table first, then atomic structure and bonding, then reactions, acids and bases, mixtures and organic chemistry. A teacher can work down the page across a term and hand out a different grid each week. There are companion hubs for biology and the solar system, plus a wider science collection.
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 โ click a card, print the page.
Use one as a five-minute starter to surface the vocabulary before a lesson, or as a recap at the end of a unit โ the answer key doubles as a term list for revision. Most suit students from about eleven up; states of matter and lab equipment work earlier than bonding or organic chemistry.
