States of Matter & Phase Changes
We will be observing three states of matter: ___________________, ________________________ and _______________________.
These states of matter are capable of undergoing a change so that they turn into another state of matter. For
example, a solid ice cube can change into liquid water. How and why are these states of matter capable of
changing? Energy! In the upcoming lessons we will learn about energy transfer and how a change in energy can
cause a phase change. A phase change occurs when __________________________________________________________________.
First, we will learn when the 6 phase changes occur: Melting, Freezing, Evaporating, Condensation,
Sublimation and Deposition.
 Draw 9 atoms as a solid, liquid, and gas
 Label the 6 phase changes that can occur.
