Matter and it's Physical Properties
Remember what Matter is?
 Anything that takes up space and has mass
Do you remember your
States of Matter?
 Solid
 Liquid
 Gas
 Plasma
(we don’t worry
about plasma in
5th grade)
So what are all the physical
properties of matter?
 Remember that when we learned about traits, physical traits
were those that were part of the body of the organism – not
behaviors.
 So physical properties of matter are simply the properties
that are part of the substance without changing it into a new
substance (no chemical changes).
 These are things you can detect with your senses or measure!
Examples of physical properties
We will spend most of our time on:
 Density
 Solubility
 Conductivity
 Magnetism
You should already be able to find the following using your
measurement skills!
• Length
• Mass
• Volume
Physical Properties of Matter
 Boiling Point – The temperature at which liquid matter turns
into a gas.
 The boiling point of water is
100oC.
Physical Properties of Matter
 Melting Point – The temperature at which solid matter turns
to liquid
 Freezing Point – The temperature at which liquid matter
turns to solid
 The freezing/melting point
of water is 0oC.
Physical Properties of Matter
Mass
 The amount of matter in an object
 The gram is the metric unit for mass
Physical Properties of Matter
Volume
 The amount of 3-dimensional space an object occupies. Also
known as Capacity.
 Can be measured by the amount of water an object can move
or displace.
 All states of matter have
volume, but only solids
have a set shape.
Physical Properties of Matter
 Density – The amount of matter within a certain amount of
volume. We will focus on relative density in water.
 Which do you think has a greater density?
Bowling Ball or Soccer Ball
Physical Properties of Matter
 Density – The more dense an object the more it will sink and
the less dense an object the more it will float in water.
Physical Properties of Matter
 Solubility – The ability for a substance to dissolve
 In a solution ingredients of a mixture are spread out evenly
throughout. You usually cannot see the dissolved ingredients
(other than through color change).
Physical Properties of Matter
 Magnetism – Property of attraction to a magnet.
 The entire Earth has a magnetic field!
Physical Properties of Matter
 Conductivity: Ability of a substance to allow electricity or
heat to pass through it.
 Metals are good conductors of heat and electricity.
 Materials known as insulators block heat or electricity.
Thermal (heat) insulators are things like styrofoam
Electrical insulators are things like: rubber, plastic, cotton
