We will be identifying whether materials are solids, liquids or gases. Can an object be made up of more than 1 state of matter? The three states of matter have different properties. Which one can be poured? Which one fills the container or space?
We will be exploring and observing how materials change state when they are heated and cooled. Materials have different melting points, which means that some melt at lower temperatures than others.
Evaporation and condensation are two processes through which matter changes from one state to another. Matter can exist in three different states: solid, liquid, or gas. In evaporation, matter changes from a liquid to a gas. In condensation, matter changes from a gas to a liquid.
