World of Change      by Jeffrey Hale ©1999

These are the states of matter... solid, liquid, and gas.
Under certain conditions the state may not last.
It's a cha-a-ange It's a physical change

Have you seen a physical change?
When molecules go through a phase
Solid to liquid, liquid to gas
It's the heat of matter that matters in a physical change

Here's an experiment that can't be beat
Turn milk into ice cream for a tasty treat.
It's a cha-a-ange It's a physical change

Have you seen a physical change
when molecules go through a phase
Solid to liquid, liquid to gas
It's the heat of matter that matters in a physical change

Mix baking soda and vinegar then stand back
These are two chemicals that will react.
It's a cha-a-ange It's a chemical change

Have you seen a chemical change?
When molecules rearrange.
Compounds change into something new.
It's the kind of matter that matters in a chemical change.

C₆H₁₂O₂ is a very sweet sugar molecule.
For some energy it will do when it breaks on down to CO2

 repeat chorus.. ...It's the kind of matter that matters-repeat 3X in a chemical change.
