The three (and four) states
Everything around us is MATTER, and this puzzle gathers the forms it takes. You'll be finding the three everyday states — SOLID, LIQUID and GAS — plus the super-hot fourth state, PLASMA, and the tiny ATOM, PARTICLE and MOLECULE that make them all up.
Because every new puzzle reshuffles the lab, no two states of matter word searches are the same. One round a backwards EVAPORATE hides in a corner; the next a diagonal MOLECULE appears across the middle.
Changing from one state to another
Add or remove HEAT and matter changes state, and the words are here. Watch a SOLID start MELTING into a LIQUID, see water reach BOILING and EVAPORATE into VAPOUR and STEAM, then CONDENSE back again, or FREEZE into ICE. There's the rare SUBLIME change from solid straight to gas, the FROZEN and the FLOW, and the way VOLUME and shape CHANGE along the way.
It's a great fit for a science topic on materials. Tracking down E-V-A-P-O-R-A-T-E turns spelling practice into an experiment.
How to play
Drag across a word, or click its first and last letter — both work. Each word you spot locks in with its own colour and ticks off the list, so you always know what's left to find.
