4. Objectives
Objective 1: Students will be able to demonstrate an example of a physical change
Objective 2: Student will be able create mixtures and solutions
Objective 3: Students will analyze a classroom demonstration to determine if it is an example of a mixture, solution or physical change
Objective 4: Students will plan and construct a classroom demonstration that includes an example of a mixture, solution and a physical change

5. Matter
matter is anything that has mass and occupies space

6. States of Matter
Matter can be found in three states: liquid, solid, or gas

7. Liquid
flowing freely but of constant volume (amount of it doesn’t change) such as oil or drinking water

8. Gas
expands freely to fill any space available (air, steam, fog)

9. Solid
Firm and stable in shape; not liquid or fluid like ice or rocks

10. Physical Change
physical change is when matter changes from one state to another or is changed in shape

12. Mixture
two or more different kinds of matter or substances, each of which keeps its own physical properties

13. Solution
mixture in which substances are dissolved to create one substance
