Matter The Atom

2. Matter The term matter describes all of the physical substances around us: your table, your body, a pencil, water, etc.

3. Matter Anything that has mass and takes up space (has volume) It can be a solid, liquid, or gas. Made up of different kinds of atoms Everything is either matter or energy

4. Matter is made of atoms

5. Models In the case of atoms, scientists use large models to explain something that is very small . Atoms are so small, it would take about 1,000,000 lined up in a row to equal the thickness of a human hair. Models of the atom were used to explain data or facts that were gathered experimentally.

9. Heat When molecules of any kind of atoms get more energy in them than they had before, they move faster, and we call that "heat". When the molecules move faster, they hit against each other and bounce apart, and so they end up further apart from each other than they were before. Things are hot if their molecules are moving quickly, and cold if their molecules are moving more slowly. Temperature is a way of measuring how fast the molecules are moving.
