Matter is anything that has mass and takes up space. It exists in three states - solid, liquid, and gas. All matter is made up of tiny particles called atoms that are too small to see with the naked eye or a standard microscope. Mass is a measure of the amount of matter in an object, measured in kilograms. Volume is the space an object occupies, measured in cubic meters. Density measures the amount of mass concentrated in a given volume, with denser materials having more mass in the same space.

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. 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.

5. VOLUME
• VOLUME is the amount of space that a body
occupies. The standard unit ofvolume 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.

6. DENSITY
• DENSITY is a measurement of the
amount of matter, or mass, in a
particular space, or volume.
• Ex. Steel is dense because it
concentrates a lot of matter in a
small amount of space.Chalk and
cork are not very dense. They are
light, with lots of air spaces inside
them.
