Three States of Matter

Learning objective: Students will be able to classify the pictures as solids,

liquids, or gases.

Student goals: I will know what matter is.

I will know what the three states of matter are and their properties.

I will know how to classify items as solids, liquids, or gases.

What is Matter?

The basic definition: Matter is anything that takes up space.

What are the States of Matter?

There are three states of matter: solids, liquids, and gases.

What is a Solid?

A solid is the simplest state of matter.

A solid has these three main properties: It has a definite shape.

It has a definite mass.

It has a definite volume.

A solid will always look the same and take up the same amount of space.

Examples of Solids:

Colored Pencils

Basketball

Chair

What is a Liquid?

A liquid is the most fluid and ever-changing state of matter

A liquid has these three main properties: It does not have a definite shape. It has a definite mass. It has a definite volume.

A liquid will always take up the same amount of space and take the shape of its container.

Examples of Liquids:

Orange Juice

Cough Syrup

Salad Dressing

What is a Gas?

A gas is the most complex and difficult to understand state of matter

A gas has these three main properties: It does not have a definite shape. It does not have a definite mass. It does not have a definite volume.

A gas does not always weigh the same or take up the same amount of space.

However, like a liquid, a gas will always take the shape of its container, no matter the size or shape of that container.

Examples of Gases:

Smoke

Air

On your worksheet, decide whether these items are solids, liquids, or gases.

Key Points: Matter is anything is anything that has mass and

takes up space. The three states of matter are:

solids, liquids and gases.

Solids: have a definite shape, mass and volume.

Liquids: have a definite mass and volume, but not shape.

Gases: do not have a definite mass, volume, or shape.

NASA Mission

NASA Mission: Prompt

A spaceship has arrived back home in Florida from its latest exploration to Mars.

The astronauts have brought home several items that they wish for scientists to

classify. NASA has asked for you to classify these items into groups based on

what you think they are. So that other scientists can understand your work,

NASA is asking that you name each item and sketch a drawing of these items.

Below is the chart that NASA has requested you to use. They believe that these

items are going to fit into three different groups: solids, liquids, and gases. There

are five case files for you to sort through with your team. Will you figure out

where the items belong? Happy classifying!
