Gases

2. Matter
• Matter is anything that takes up space.
• Everything on earth is matter.
• Matter exists in three states:
• Solids
• Liquids
• Gases

3. Solids
• A solid does not change size or shape
when it is moved.
• You can measure the shape and the
mass of a solid.
• Examples: book, apple, shoes
• Can you think of anymore?

4. Liquids
• Liquids do not have their own shape.
• They take the shape of its container.
• Examples: water, juice, milk
• How do liquids look and feel?

5. Gases
• Gas is matter that is all around you and
fills many kinds of things.
• For example, bubbles, balloons, and balls
are filled with gas.
• Air is also a gas.
• Gas takes the shape and size of the
container
• Can you think of another example?

6. Molecules
• Solids, Liquids, and Gases are made up
of tiny particles called molecules.
• As a class we can act as if we are the
molecules that make up solids, liquids,
and gases!
• Everyone stand up and get ready to
have some fun!

7. Solids
• Get as close as possible to one
another and hold hands.
• The molecules in a solid are very close
together and do not move very much.

8. Liquids
• To act as a liquid we still hold hands,
but we spread out some and move
together.
• The molecules of a liquid are loosely
tied together and flow freely.

9. Gases
• Everyone let go of your neighbor’s
hands and spread out.
• Walk around the room and slightly
bump into one another, like bumper
cars.
• The molecules in a gas have a lot of
space between them and move freely.
