Lesson 1.1 Matter has mass and volume

Matter has mass
and volume.
All objects are made of
Matter makes up all of the objects
and living organisms in the universe.
Matter is anything that has mass and
takes up space.
Matter is made of the particles called
atoms, which are to small to see.
Your body is matter
The air is matter
Water is matter
All objects are made of
Not everything is
 Light is not matter
Light does not take up
any space
 Sound is not matter
Mass is a measure of the
amount of matter
Different objects contain
different amount of matter.
Mass is a measure of how
much matter an object
Ex: a metal spoon vs. a plastic
Ex: an elephant vs. a mouse
Measuring Mass
When measuring mass you
compare the mass of the object
with a standard amount, or unit,
of mass.
How can you compare the masses
of two objects?
A pan balance
Measuring Weight
Weight is the downward
pull on an object due to
Weight is measured using
a scale.
The standard unit for
weight is the newton (N).
A common unit for weight
is the pound (lb.).
Measuring Weight
Mass and weight are similar but not the
Mass describes the amount of matter
an object has.
Weight describes how strong gravity
pulls on matter.
Ex: The Moon has less gravitational pull
than Earth so an object will weigh less on
the Moon.
The same object will have the same mass
on the Moon or on Earth.
Volume is a measure of the
space matter occupies.
 Matter
takes up space.
 The
amount of space that
matter in an object
occupies is called the
object’s volume.
 The
tubes on the right all
have the same amount of
Determining Volume by
 There
are different
ways to find the
volume of an object.
Volume = length x width
x height
Measuring Volume by
Although a rock has a regular
shape, a rock does not.
There is no simple formula for
calculating the volume of
something with a irregular shape.
The method of measuring the
volume of an irregular shape is
called displacement.
Measuring Volume by
Add water to a graduated cylinder.
Note the volume of the water by
reading the water level on the cylinder.
Submerge the irregular object in the
water. The water will be displaced, or
moved upward. Note the new volume
of the water with the object in it.
Subtract the volume of the water before
you added the object from the volume
of the water and the object together.
The results are the volume of the object.
Measuring Volume by
You measure the volume of liquid by measuring how
much space it takes up in a container.
The volume of a liquid is usually measured in liters (L)
or milliliters (mL).
1 liter (L) = 1000 milliliters (mL)
Milliliter is equivalent to cubic centimeters.
1mL = 1 cm
If you had a box with a volume of one cubic
centimeter and you filled it with water, you would
have one millimeter of water.
