Confusing Evaporation and Condensation in the Water Cycle

Students say water vapor forms by condensation and liquid water forms by evaporation.

Quick check

Why students make it

Students often match evaporation with clouds because water seems to disappear upward. They also think condensation means water is leaving a surface because droplets show up on the outside of a cold cup.

The rule done right

Evaporation is liquid water changing into water vapor gas. Condensation is water vapor gas changing into liquid water droplets.
