Concord Consortium: Stem Resources: Phase Changes

This activity reviews of states of matter, then relates them to atomic movement as it is affected by attractions between atoms and the addition of energy. Latent heat and evaporative cooling are also topics covered. Multiple-choice and short answer questions are found interspersed with interactive media and short text. Teachers have the opportunity to register, granting them access to students' progress, pre- and post-tests, and a full teacher guide/ answer key.
