PHYSICAL CHANGE
CHEMICAL CHANGE

1

Any characteristic we can observe or measure without changing the chemical composition of the substance

Required

1

Changes to a substance's appearance/form but not its chemical composition

1

A characteristic of a substance that can only be seen by changing the chemical composition of a substance

1

These changes impact a substance's chemical composition, causing a new substance to be created

EXTRA CREDIT: When bubbles form in a liquid, how do we know when it is a chemical change (effervesce) and not just a state of matter change?

Extra points if you can correctly use one of our experiments to support/explain your answer.
