Matter Solids, Liquids, and Gases START END

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

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?

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

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. • Can you think of another example?

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!

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.

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.

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.

Can you think of an object that can act as a solid, liquid, and a gas?

Conclusion • Now that we have reviewed solids, liquids, and gases it is now time to work in the Lab and understand how matter behaves more concretely. START END
