This document discusses different types of matter. It explains that matter can be solids, liquids, or gases. Solids keep their shape, liquids flow and change shape, and gases have no shape. The document describes how to measure and change the state of matter through heating and cooling. Key terms are defined, including solid, liquid, gas, mixture, and mass.

15. School-Home Connection
Tell a family member what you have
learned about matter. Take turns
naming solids and liquids you use at
home.
Hands-On Activity
1. Make a tracing of your hand.
2. Measure each finger. Write the
length of each finger.
Think About the Reading
1. What questions do you have
about solids, liquids, and gases?
2. What can you do to find the
answers to your questions?
