Part One – What is Matter?
What do these things have in common?
a scooter
your teacher
strawberries
some books
All of these things are matter. Matter is all around you. Any object
you can see, taste or feel is made of matter, including people, things,
food and even water.
Here’s what you need to know about matter:
All matter takes up space. (This part is easy.)
AND
All matter has mass.
So, what is mass? Mass is how much matter an object contains. Objects
that contain more matter have a higher mass.
Mass is measured in grams. We use a balance to measure mass.

Part Two– Matter is made of Atoms
All matter is made of very, very small parts called atoms.
Atoms are too small to be seen with your eyes or even a microscope.
Different kinds of matter are made of different kinds of atoms. Some
matter is made of only one kind of atom. Gold is made up of one kind of
atom - gold atoms.
Some kinds of matter are made of more than one atom. Salt is made up of
two different kinds of atoms.

Different kinds of matter are made of ____________________ kinds of
atoms. Some matter is made of only ____________________of atom.
Gold is made up of one kind of atom - gold atoms.
Some kinds of matter are made of ____________________ than one atom.

Part Three – Using Properties to Describe Matter
How would you describe these objects if you didn’t know what they were?
Write your answers next to the pictures.
(Hint: Use words that tell size, shape, color, or texture.)
When you describe objects by using:
●
●
●
size
shape
color
texture (the way an object feels)
you are talking about an object's properties. A property describes how
an object looks, feels, or acts. Different objects have different properties.

Part Four– Physical Properties of Matter
Size, shape, color and texture are not the only properties of matter. There
are other properties of matter that can be measured without changing how
matter looks - these are called physical properties.
When you look at oranges, you know that they are oranges because of
their color, shape, and smell. You also know they are oranges because of
their mass, volume, and density.
We already know that mass is the amount of matter an object has. It is
measured in grams using a tool called a balance.
Volume is the amount of space an object takes up. Volume is also the
amount of mass that a container will hold. Volume can be measured using
a graduated cylinder. The unit of measure for volume is the liter.
Density is another physical property. Density is the amount of mass in a
given space.

Part Five– Chemical Properties of Matter
Chemical properties are different than the physical properties you can see
just by looking at an object. Chemical properties are properties that can
only be seen when matter changes.
When a piece of paper burns, it turns into a black substance (ashes.) It no
longer looks like paper. After the flame goes out you can no longer burn
the new substance. This is because the chemical properties of the paper
have been changed.
Name:___________________________________________________ Date: _________________________
Listed below are several properties of matter. Use the T-list to sort the
properties into physical and chemical properties. (Remember, chemical
properties have to do with change.)
A jug holds two liters of
water
A paper clip is three
centimeters long
Physical Properties
Cherries are red
Milk can spoil
Paper can burn
Sandpaper is rough
Chemical Properties
Part Six – Properties Can Change
Matter is constantly changing. Ice in your
soda melts, glass breaks, paper is ripped.
When ice in your soda melts where does it
go? What does it become?
When you drop the ice cube into a liquid,
it begins to melt because the temperature
is higher than that of the ice cube. It's like
putting a snowman on your front lawn in
July. The ice cube becomes liquid water.
This is an example of a physical change.
The solid water turned to liquid water. It doesn't turn into soil or macaroni.
It remains water. If it did change into soil or macaroni, your drink would
taste terrible and you would have an example of a chemical change.
Chemical changes are when substances change into
other substances. If it could happen, ice changing into
macaroni would be an example of a chemical change.
A real example of a chemical change is spoiling milk
or burning toast. Milk needs to be in the refrigerator or
else it will go bad. If you've ever seen or smelled
spoiled milk, it is not a pretty sight. The milk gets a
sour odor and becomes lumpy.
Unlike physical changes, you cannot reverse chemical changes. Once
matter changes, it cannot go back to the way it was before. You can melt
ice to get water and freeze that water to get ice again, but you cannot make
milk unspoiled.
