1 Exploring Matter Unit Review

2 What is Matter? Matter is anything that takes up space and has weight. Matter has three forms. Matter can be a solid, a liquid, or a gas. Matter is made up of tiny particles called molecules.

3 What do we know about solids? Solids take up space and have mass. Solids have a shape of their own. Solids can be described by their physical properties. Solids can be measured.

4 What do we know about liquids? Liquids take up space and have mass. Liquids do not have a shape of their own. Liquids take the shape of their container. Liquids can be measured (mass and volume).

5 What do we know about gases? A gas takes up space and has mass. A gas takes the shape of its container. A gas is the only kind of matter that always fills all the space inside a container. The mass of a gas can be measured.

6 Physical Changes in Matter Cutting Mixing Shaping Changing from one state of matter to another. Melting Freezing Evaporating

7 Other changes in matter Some changes in matter are reversible. Some changes in matter are irreversible. Rusting, burning, and cooking are irreversible changes.

8 Wonderful Water Water can be a solid, a liquid, or a gas. Water as a solid may be ice or snow. Water as a liquid may be drinking water. Water as a gas is water vapor. Heat changes water from one form to another. Water in all three states make up the water cycle.

9 This concludes our study of matter.
