Solids, liquids and gases

Today in science the children were learning about different states of matter and reversible changes. We had fun seeing liquid evaporate to a gas,steam condense into a liquid, water freezing into ice and melting again, and a solid turning straight into a gas, missing out the liquid stage entirely! Can anyone remember the name of this process? They then made some lovely posters explaining the properties of solids, liquids and gases, and how they can change state.
