A blank phase-change diagram with an empty box at every label and a word bank of nine terms underneath: solid, liquid and gas, plus melting, freezing, evaporation, condensation, sublimation and deposition. The particle pictures and the solid-or-dashed arrows are clues. The answer key on page two shows every label in red.

Warm up with the simulation and the label quiz in the interactive states of matter, then complete this sheet on paper. For a harder version without a word bank, print the numbered states of matter diagram.

Tips for using it

  • Label the three states first from the particle pictures, then the arrows.
  • Remind your child that solid arrows add heat and dashed arrows remove it.

Questions

What are the nine words on the worksheet?

Solid, liquid, gas, melting, freezing, evaporation, condensation, sublimation and deposition.

Is there an answer key?
