What to know Melting changes solid ice into liquid water. Evaporation changes liquid water into water vapor at the surface. Boiling changes liquid to gas throughout the liquid when enough heat is added.
🔎 Think like a scientist An ice cube melts into liquid. A puddle slowly evaporates, while heated water may boil rapidly.

What to know Freezing changes liquid water into solid ice. Condensation changes water vapor into liquid droplets. Cooling removes heat energy from water.
🔎 Think like a scientist Droplets outside a cold cup form when water vapor in the air cools and condenses; they did not leak through the cup.

What to know Heating and cooling can reverse water’s changes of state. The process name describes the change, not merely the starting state. Look for evidence: droplets, disappearing liquid, bubbles, or solid ice.
🔎 Think like a scientist Solid → liquid is melting; liquid → gas is evaporation or boiling; gas → liquid is condensation; liquid → solid is freezing.
