## What is Matter? What is State of Matter?

Matter is anything that has mass and takes up space.

State of matter is what matter looks like, feels like, and how it acts.

You will learn the three states of matter and how you can recognize each one by its properties.

## Solids

A solid is usually hard but often can be soft. Solids have a definite shape, meaning the shape will not change unless you do something to it . The molecules in a solid are stationary and are packed tightly together. Some examples of solids are: a desk, a ball, a book, and a pillow.

## Liquids

Liquids flow and take the shape of the container they are in. Liquids have a definite volume but not a definite shape. The molecules in a liquid move around slowly and are farther apart than the molecules in solids. Some examples of liquids are: water, the ocean, lava, and honey.

## Gases

Gases do not have a definite shape or volume. Gases can fill a container of any size or shape, no matter how big the container is. The molecules will spread out to fill the whole space. The molecules in gases are moving constantly or fast and are very far apart. Some examples are: helium in balloons, bubbles in soda, and the atmosphere of the earth.
