Physical changes alter the physical properties of a substance but do not change its chemical composition, while chemical changes alter both the physical properties and the chemical composition of a substance. The presentation aims to help students identify whether a change shown in pictures is a physical change, which does not create a new substance, or a chemical change, which does create a new substance.

1. LOOK AT THE PICTURES AND IDENTIFY THE
TYPE OF CHANGE; PHYSICAL CHANGE OR
CHEMICAL CHANGE
