Matter
True or False?

Water, clay, rocks and trees are all
examples of matter.
TRUE
True or False?

Matter is anything that takes up
space and has mass.
TRUE

Can you think of six different
properties of matter? (Hint: One of
the properties is “color.”)
1.) color
2.) size
3.) shape
4.) texture
5.) flexibility
6.) luster

What is luster?
These pearls
have luster.
Luster is how an object shines in
the light. A gold ring has luster. A
piece of notebook paper does not.

What is volume?
Which has the
greatest volume?
Which has the
least volume?
Volume is how much space an
object takes up.
A beach ball has more volume
than a bowling ball.

What is density?
Density is how close the
particles are packed
together in an object.
Madison’s lead bar is
more dense than the
plastic gram stacker that
we passed around.

Which is more dense water or
oil?
Water

What is mass?
Mass is how much
matter is in an object.
A bowling ball has more
mass than a beach ball.
Mass and Weight

Miss Henry keeps telling me that
mass and weight are not the same
thing. Why does she keep saying
that?
Remember: Mass is how
much matter is in an
object.
Mass and Weight

If a cat has a mass of 6 kilograms on
earth. It will still have a mass of 6
kilograms on the moon. The matter
of the cat doesn’t change.
Mass = 6
kilograms
Mass = 6
kilograms
Mass and Weight

Have you ever seen astronauts jumping
on the moon? They seem to be light as
feathers. Their mass didn’t change.
Something else changed. What do you
think changed?
Weeeeee! My
mass didn’t
change. Why
can I move like
this?
Mass = 6
kilograms
Mass = 6
kilograms
Mass and Weight

If a cat has a mass of 6 kilograms on
earth. It will still have a mass of 6
kilograms on the moon. The matter
of the cat doesn’t change.
Mass = 6
kilograms
Mass = 6
kilograms
GRAVITY CHANGED!

Weight depends on gravity.
(In science, weight can be measured in
Newtons.)
Mass = 6
kilograms
Weight = 58
Newtons
Mass = 6
kilograms
Weight = 9
Newtons
