OA4.1 Understand properties of
matter
Word
Definition
Matter that is made of
1. Element Only one type of atom
Cannot be broken down
Can exist as atoms or
molecules
Carbon, hydrogen, and oxygen are all
elements.
The picture is of the element zinc in
hydrogen chloride.

periodic table
• Scientists use the
periodic table to
organize elements.
• Each element has its
own special place on
the table.
• The places are decided
by the characteristics of
the element.
Word
2. Molecule
Definition
Two or more atoms
of the same element,
hat are chemically
bound together.
Hard to separate
Example: Oxygen gas (2
oxygen atoms), Ozone (3
oxygen atoms), Nitrogen
gas (2 nitrogen atoms)

Compounds
Definition
Atoms of two or more
different elements
bound together.
Hard to separate
Example: Water
(hydrogen and oxygen),
Carbon dioxide (carbon
and 2 oxygen), carbon
monoxide (carbon and 1
oxygen)

Word
4. Mixture
Definition
A substance made of 2
or more elements or
compounds that are
mixed together
Easy to separate
Example: mud (soil and
water), concrete
Picture
Concrete mixture:
The thing to remember about mixtures is that you
start with some pieces, combine them, and then you
can do something to pull those pieces apart again. You
wind up with the same molecules (in the same
amounts) that you started with
Word
5. Solution
Definition
A mixture where one
substance dissolves,
(seems to disappear) when
it’s put into another.
Easy to separate
Example: salt water,
kool aid

Salt
Made up of Atoms

Closure: five finger summary
Trace your hand on a separate sheet of paper.
In the palm of your hand write the word
“MATTER”
Write a sentence about what you learned
today…one in each finger. So you will have a
total of 5 summary sentences written in each of
your fingers (+ thumb).
