McDonalds© informed us that
its Big Mac® is made of: two all beef patties, special sauce, lettuce,
cheese, pickles, onion on a sesame seed bun! What does this have to do
with matter? Well, a Big Mac®, like most matter in the world, is made
up of smaller parts which makes the whole. All matter is made up of atoms
that are far too small to see.
In this unit you will learn that atoms are in perpetual motion, and
the more energy atoms contain the faster they move. You will also explore
how atoms combine to form molecules. All matter is made up of atoms and
molecules with measurable mass, volume, and density. Density is a measure
of the compactness of matter. Have fun as you explore the structure of
matter in this section.
