World of Change     Jeffrey Hale ©1999

These are the states of matter... 

solid, liquid, and gas.

Under certain conditions the state may not last.

It's a change 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 change 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 change 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

It's the kind of matter that matters-repeat 3X

In a chemical change
