The whole periodic table of ideas in one grid
Chemistry is the science of what everything is made of, and this puzzle bottles up the essentials. You'll be hunting for the building blocks — the ATOM, MOLECULE and ELEMENT — the particles inside them, from PROTON to ELECTRON, and the lab kit that brings it to life, like the BEAKER and FLASK.
Because every new puzzle runs a different experiment, no two chemistry word searches are the same. One round you're tracking a CATALYST through the diagonals; the next a backwards REACTION is fizzing in the corner.
A perfect fit for the classroom
Chemistry vocabulary can be tricky, and a word search is a friendly, low-pressure way to make it stick. It's a popular choice for science lessons, revision warm-ups and homework clubs.
With no timer, it's a calm bit of study disguised as fun. Spotting PERIODIC tucked diagonally into a corner is a small, satisfying breakthrough.
How to play
Drag across a word, or click its first and last letter — both work. Each word you find locks in with its own colour and ticks off the list, so you always know what's still in the flask.
Want a bigger challenge? Switch to Medium or Hard for a larger grid with diagonal and reverse words. Stuck on one? Tap Hint for a nudge, or Solve to complete the experiment at once.
