MATTER
You see many things in this world, like human
beings, animals, plants, air, soil, water, plastic,
metals, wood, paper etc. All these things are made
up of matter. Everything that occupies space and
has weight is matter. There are three types of
matter, that are solids, liquids and gases.
Solid Liquid Gas
(closely packed molecules) (not very close molecules) (loosely packed molecules)
MOLECULES
All matter can be split into tiny units that are not
visible to the naked eye. These tiny units are
called molecules.
Take some grains of sugar. Crush it with the help
of a rolling pin. The sugar grains become powder.
