3. Matter
Definition: anything with the characteristics of
mass and volume
A human is considered matter
because they take up space
(volume) and they have mass.
4. Not Matter
• Definition:
something that is
unrelated to matter,
and it itself is not
categorized as
matter
Thoughts do not take up space
(volume), as well it does not
have mass, it is merely a
concept that someone thinks up,
meaning it is not of matter
5. Pure Substance
• Definition: matter
that has only one
type of particle
Sugar is an example of a pure
substance, as it has only one
type of particle. * Pure
substances are composed of
elements and compounds
6. Element
• Definition: a pure
substance that has
only one kind of
particle, substance
cannot be any
simpler
Silver is a type of pure
substance which is an
element, there for it only has
one kind of particle. Pure
silver necklaces like these are
a good example of an
element.
7. Compounds
• Definition: a pure
substance that has
two or more
elements that makes
up one type of
particle
Salt is a combination of the
elements sodium and chloride,
which makes it composed of two
different elements which equal one
type of particle
8. Mixtures
• Definition: any
substance that has
two or more pure
substances
The substance that makes a T.V
screen glow is made of a mixture
of metal compounds to create
the proper wavelength. One of
the pure substances include
Phosphors.
9. Heterogeneous
Mixtures
• Definition: a type of
mixture in which its
components can be
easily seen
Soda is a type of heterogeneous
mixture because the carbon
dioxide is visible seperated from
the liquid itself.
10. Homogenous Mixtures
• Definition: a type of
mixture in which its
components are well
blended that it
seems as one to the
human eye
Grape wine contains mixtures of
alcohol, grape juice, sugar and
many other components, but it is
so well mixed that the components
can be only seen as a red liquid.
11. Mass
• Definition: the
measure of the
number of matter
contained in an
object, unlike weight
These two beakers are of
the same shape and size,
however they weigh
differently, meaning even if
two objects are similar,
their mass may be different
12. Volume
• Definition: the
amount of space an
object takes up
Without me or the clothes, the
closet is an empty space, but
once the clothes and I are placed
within, we take up the once
available space in the closet,
meaning we have volume.
13. Density
• Definition: mass per
unit volume of a
substance ( ex: its
ability to float)
A person swimming is an
example of density as a
person needs enough
oxygen in their body to
become less denser
(lighter) than water
14. Viscosity
• Definition: the
property of a fluid
that goes against the
force in which
causes the fluid to
flow
Face powder is composed with
miniscule types of fluid which
depends on viscosity to be
applied properly onto the face
15. State
Definition: the states in which matter can be
found, solid, liquid and gas
An ice Water,
cube is

state flows state of water as it

16. Conductivity
Definition: ability of a material to conduct heat or
electricity
A
boiling A wire is
pot can used to
absorb transmit
heat electricity,
and meaning it
use it has
to conduc-
cook, tivity
mean-
ing it
has
conduc
tivity
17. Physical Changes
Definition: the changing of the form or state of a
substance but not the substance itself
The part
of the
paper
Crumpling with
and ripping absorbed
the tin foil water
changes its changes
form, but its form,
not itself as as it is
it is still softer,
tinfoil however
neverthe- it is still
less paper
18. Chemical Changes
Definition: a chemical reaction happening within
a substance which changes it into a new
substance with different properties
Once the Once the
paper is egg is fried,
burned, its it becomes
properties cooked and
or compo- no longer
nents are
liquid, its
changed,
making it components
a new are changed
substance during the
called frying, thus
burnt the name,
paper. fried eggs.
