They take up space
They have mass
Mass is how much there is of an object. It is related to how much something weighs, but mass and weight are two different things.
PROPERTIES OF ALL OBJECTS:
Objects that take up space and have mass are called matter.
All matter is made up of lots of tiny particles that are too small to be seen by the eye.

SOME EXAMPLES OF MATTER?
Physical properties refer to the characteristics of an object that can
be seen without changing how that object looks.
Some examples of physical properties are:
Shape
Volume
Movement of particles
Spacing of particles
PHYSICAL PROPERTIES
When we describe matter, we use the physical properties to
talk about the states of matter.For example, if I was
describing a solid I would say that ALL solids have a definite shape and a definite volume.
Notice I didn’t say that they are hard. I didn’t say that because not ALL solids are hard. Think about your hair. Is it
hard?
PHYSICAL PROPERTIES
SolidsEx. Rocks, chairs, clothes, paper, ice, etc.
LiquidsEx. Water, soda, milk, juice, etc.
GasesEx. Oxygen, helium, carbon dioxide, etc.
THE STATES OF MATTER
Ways to describe solids:ALL solids have a definite
shapeALL solids have a definite
volumeThe particles in ALL solids are
packed closely togetherThe particles in ALL solids
vibrate in place.
SOLIDS
There are two ways to find the volume of a solid. You must determine the type of
the solid before you can find the volume.The two types of solids are rectangular
solids and irregular solids.
FINDING VOLUME OF A SOLID
An example of a rectangular solid would be a book. A book has a length, width, and volume.
To calculate the volume of a book, you would first measure the length, width, and height. Then, you multiply those
values together.
Length x Width x Height = Volume
VOLUME OF RECTANGULAR
SOLIDS
To find the volume of an irregular solid, you will need to use water displacement with a graduated cylinder.
Water displacement means that you would put water in the graduated cylinder. Then, drop the solid into the cylinder. Then however much the water rose would be the volume of
the solid.Volume of irregular solid = new water
level – original water level.
VOLUME OF AN IRREGULAR SOLID
Ways to describe liquids:
ALL liquids have a definite volume
ALL liquids take the shape of the container
they are placed in.The particles in liquids
are relatively spread out.The particles move apart from each other and flow
from place to place
LIQUIDS
To find the volume of a liquid, scientists use a tool called a graduated cylinder.
A graduated cylinder is similar to a measuring cup in that it shows measurements in increments on the outside of the
container.
FINDING VOLUME OF A LIQUID
Ways to describe gases:ALL gases have no definite
volume.
ALL gases take the shape of their container, filling all of
the available space.
The particles in a gas are spread out in the available
space.
The particles move easily through the available space.
