
All materials exist as a Solid, Liquid or
Gas

All materials are made up of very very
small particles held together by forces!
Solids
In a Solid, the
particles are held
very close together
so they can hardly
move.
 They can just
VIBRATE in one spot.

Liquids

In a liquid, the
particles are not so
tightly packed, so
they can move a
little.
Gases

In a gas, the particles
are spread apart and
can move easily

Particle Theory
All matter is made up of very small
particles
2. All particles in a pure substance are the
same. Different substances are made of
different particles
3. The particles are always moving. As the
particles gain energy (heat), they move
faster
4. The particles in a substance are attracted
to one another.

Elements
Our planet is made up of over 100 different
kinds of elements.
 These elements are organized in a Periodic
Table.
 Elements can join together to make
MOLECULES, or they can exist as separate
particles called ATOMS.
 Each element has a special symbol on the
Periodic Table.

Periodic Table - Handout
Instructions:
Periodic Table
 Draw the "staircase" line that separates the
metals from the non-metals so that it is
easy to see.
 Use the key to shade in the gases, the
liquids and the solids.


Element Word-search – Use your Periodic
Table to write the SYMBOL for the element
beside the word that you are trying to find.

Mixtures
Classification on Matter
MATTER
yes
no
Can it be separated?
MIXTURE
yes
PURE SUBSTANCE
no
Does it look the same
all the way through?
Homogeneous
Mixture
(solution)
Heterogeneous/
Mechanical
Mixture
yes
no
Are the particles made
of more than one kind of element?
Compound
Element
Pure Substances – Two Types
1.
Elements


composed of identical atoms
EX: copper wire, aluminum foil, oxygen gas
2.
Compounds

composed of 2 or more different
kinds of elements

EX: table salt, made from sodium
and chlorine (NaCl)
Mixtures – Two Types

A combination of 2 or more pure substances
that have been mixed together
1. Homogenous

Solutions
 You can only see one "phase"
 This means it looks the same
throughout the whole solution
– EX: Coke
2. Heterogenous

Mechanical Mixture
 Does not look the
same throughout
 Could have more than
one layer
