Physical and Chemical Properties Lab 24 T Prior Knowledge Questions Do these BEFORE using the Gizmo Describe three qualitative physical properties of each of the following chemicals. Make sure that you are using the proper vocabulary terms for qualitative physical properties.

All substances have distinct physical and chemical properties and may undergo physical or chemical changes. Physical properties such as hardness and boiling point and physical changes such as melting or freezing do not involve a change in the composition of matter. Chemical properties such flammability and acidity and chemical changes such as rusting involve production of matter that differs from that.

Students should identify that the physical properties of the substances change during a physical reaction while the chemical properties do not change. Some students get the idea that only chemical reactions can change the properties of a substance. However it is important that students realize that physical reactions change the properties of substances as well.
