Hold the clip
Easy names the sample and the state — Slide heat until fog reads as Gas. Hard names the change: Melt, Freeze, Evaporate, Condense.
Slide heat
The thermometer is a glass rail. Solid at the bottom, Liquid in the middle, Gas at the top. Release the clip when the particles match.
The pan holds
A hit scores Reads and keeps the beaker on that state so you can see why. Tap Next read for the next sample. A miss says Too hot or Too cold — and what the particles need.
Hold the clip
A glass beaker sits on a burner. Slide heat and watch a lattice vibrate, a pool slide, or vapor fill the glass.
The pan holds
A hit freezes the read. Particles stay packed, slide, or spread — then you see why before the next sample.
Next read
Hard is a phase change: Melt, Freeze, Evaporate, or Condense. Three lives. Streak score.
Solid particles stay packed and keep a shape. Liquid particles slide and take the pan's shape. Gas particles spread out and fill the space. Heating or cooling moves matter between those states.
The pan holds
Kids see why the clip belongs there after the read locks — not a flash and a new vial.
A beaker, not a word list
Frost, a meniscus, and steam are the prompt. The clip is fat enough to hold.
No. The board stays on Solid, Liquid, and Gas plus Melt, Freeze, Evaporate, and Condense.
Yes. It is a game slug with scores, the same class loop as the math boards.
