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.
