Matter
Anything that
has mass and
takes up space.

3 basic states of
matter

Mass
Measure of the
total quantity of
matter in an
object.
Measure with a
balance.

Weight
Measure of the
pull of gravity on
an object.
Measure with a
scale.

Volume
The amount of
space an item
takes up.
Measured by
water
displacement.

Multiple Choice

In a lab, a scientist has a beaker of pure water and a battery at the bottom. When he places a lightbulb in the water, the light bulb does nothing. He then adds salt to the water, and places the lightbulb in the water with salt in it, and the lightbulb lights up. What physical property was produced in the water when salt was added to the water?

• solubility

• flammability

• malleability

• conductivity

Multiple Choice

If you poured three liquids (that do not mix completely) into a cup, how could you tell which one is the densest liquid?

• The liquid that is floating on top is the densest liquid.

• The liquid that settles to the bottom is the densest liquid.

• The liquid with the deep red color is the densest liquid.

Element
An substance
that cannot be
broken down
any smaller.

What an atom looks like…

•The center of an atom is called
the nucleus.

• Protons and Neutrons are located

here.

•Electrons are moving around
the nucleus in an empty space
called the electron cloud.

Parts of an atom

•Protons = Positive = inside nucleus

•Neutrons = NO charge = inside nucleus

•Electrons = negative = outside nucleus
