2. WHAT IS MATTER??
• Matter is all around us. Matter is the air you are
breathing. Matter is the computer you are reading
from now. Matter is the stuff you touch and see. And it
is more. Matter is defined as anything that
has mass and takes up space. Matter is found in 3
major states; solid, liquid and gas.

So what is matter made of? 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.
4. WHAT IS 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
cubic metre (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.
