What
is matter?
First let's find out what MATTER
is. Matter is the "stuff"
that every known object around us is made of: anything you can touch is
made of matter ... including you!
What is this "stuff"? It's
easy to think of a wall as made out of bricks, and the sea as made out
of drops of water. In the same way, everything you see around you (including
the bricks of the wall!) are made out of little bricks.
It's like the huge lego constructions
you see sometimes in toy shops: those cars, helicopters, houses and people
are all made the same way, starting from simple lego bricks!
Well, it's the same for our
world: everything is made with bricks, except they are so small you can't
see them. What are these
"bricks"? They are called particles. There are three types,
electrons,
protons and neutrons
(like having three different colors of lego).
