Division of Academics -Department of Science

Properties of Matter Benchmarks• SC.2.P.8.2 Identify objects and materials as solid, liquid or gas.• SC.2.P.8.3. Recognize that solids have a definite shapes and that

liquids and gases take the shape of the container.• SC.2.N.1.1 Raise questions about the natural world, investigate

them in teams through free exploration and systematic observations, and generate appropriate explanations based on those explorations.

• SC.2.N.1.3 Ask ”how do you know?” in appropriate situations and attempt reasonable answers when asked the same question by others.

• SC.2.N.1.5 Distinguish between empirical observation (what you see, hear, feel, smell, or taste) and ideas or inferences (what you think).

• LAFS.2.RI.2.4Determine the meaning of words and phrases in a text relevant to a grade 2 topic or subject area

• LAFS.2.SL.1.1 Participate in collaborative conversations about topics and texts with peers and adults in small and larger groups.

What is matter?

Matter is everything around us. Including you and me.Matter is the material or “stuff” everything is made of.Matter is anything that mass and takes up space.

Look around the room and identify some matter. How can we tell the matter apart?

By its properties.

What are some properties of matter?Color, texture, shape, size, odor … What are the three states of matter?

solid, liquid, and gas

What is Matter?By Pam Dillier

What is matter?What is matter?

A solid, liquid, or a gasA solid, liquid, or a gas

It takes up space and weighs something, too.It’s everywhere - that includes you and me.

Did you ever think such a thing could be true?That is matter.That is matter.

What’s a Solid?A solid’s a solid.It doesn’t change shape.It can’t move around;It stays in one place.

Your desk is a solidAnd so is your chair.Just look in the classroom—Wow? They’re everywhere.

What properties do all solids have in common?

• A solid has its own definite shape and definite volume.

• A solid keeps its shape even when it moves.

• The particles in solids are fit together very tightly and vibrate in place. Click on link below: Properties of Matter: Particle Simulator

What’s a Liquid?

A liquid moves smoothly.We say that it flowsFrom one place to another—How quickly it goes.

We know that most liquidsAre easy to see.With no shape of their own.They not like you and me.

What properties do all liquids have in common?

• Liquids have a definite volume.• Liquids take the shape of their

container.• Liquids can be poured. • The particles in liquids are not

as close together as the particles in solids and move more freely than particles of solids. Click on link below: Properties of Matter: Particle Simulator

What’s a Gas?

Air is a gas.We can’t see it, that’s true:But often we feel itIn things that we do.

It keeps up a kite.Air fills up a bubble.Without it to breatheWe would be in BIG trouble.

Department of Science

What properties do all gases have in common?

• Gases have no definite size or shape.

• A gas takes the shape of its container.

• A gas will fill all the space inside a container.

• The particles in gases move freely in all directions.

Reflection

1. What is a solid? Give two examples.Answer: A solid is a state of matter with a definite size and shape. Examples will vary.2. What is a liquid?Answer: A liquid is a state of matter with a definite size but no definite shape. Examples will vary. 3. What is a gas?Answer: A gas is a state of matter with no definite shape, size, or color. Examples will vary.

• How can matter change form?• Answer: Matter can change form in different

ways based on temperature and the Sun. Some examples are when ice melts or water evaporates.
