2. Matter
• Matter is all around us.
• Matter is defined as anything that
has mass and takes up space.
• Matter is found in 3 major states; solid,
liquid and gas.
3. Atom
• All matter is made of atoms.
Atoms are the smallest particle of
matter. They are so small that
you cannot see them with your
eyes or even with a standard
microscope.

5. Mass
• MASS is the amount of matter in a
physical body. The standard unit
of mass is the kilogram (kg). One
kilogram is the same as 1000
grams. We can measure the mass of
a body with instruments, like scales
and weighing machines.
6. Volume
• VOLUME is the amount of space that a body
occupies. The standard unit of volume is the
(mᶾ). One cubic metre is the same as 1000
litres.
• We can measure the volume of a solid body by
putting it into a beaker of water. The body
displaces some of the water and makes the
water level rise. This change in the water level
is equal to the volume of the solid body.

8. Solid
• Solids have got
a fixed shape
and a fixed
volume. These
properties can't
change. They
are rigid.
9. Liquid
• Liquids have got a
fixed volume, but
they haven't got a
stable shape. They
take the shape of
their container.
Liquids can flow
from one place to
another.
10. Gas • Gases haven't got a
constant volume or
a stable shape.
They expand to
occupy as much as
space as possible.
They take the shape
of their container.
