This document discusses the three states of matter: solids, liquids, and gases. It defines each state and provides examples. Solids have a definite shape and volume, while liquids take the shape of their container but have a definite volume. Gases spread out to fill their entire container and their volume changes with temperature. Key tools for measuring the properties of each state are also introduced, such as rulers for solids and measuring cups for liquids.

• When you blow up a ball,
gas fills the inside.
• Gas pushes out the sides
and makes the ball bigger.
• When a gas is heated it
spreads out, it fills more of
its container.
• When a gas is cooled it
fills less of its container.
