1. Physical Properties Does it Matter?

2. The Scientific Method The process of doing an experiment. A test, an investigation, an inquiry

3. Hypothesis An educated guess or prediction. Must be testable.

4. Magnetism Matter that contains iron, iron alloys, or nickel will be attracted to a magnet Not all metals are attracted to a magnet

5. Physical State Physical State 3 forms: liquid, solid, or gas Can change from one form to another by the processes of melting, freezing, evaporation, and condensation Temperature changes are involved with changes in state

6. Mass Mass is the amount of matter in an object. Mass is measured with a balance. Mass is not the same as weight. Weight is a result of the pull of gravity on an object and is measured with a scale.

7. Relative Density Sinking & Floating Weight doesn’t determine if an object will sink or float. How much space an object takes up and how much matter the object contains determines density.

8. Solubility in Water Ability of a substance to dissolve when added to water A liquid (ie: lemon juice), a solid (ie: powdered drink mix), or a gas (ie: carbon dioxide) can be dissolved in water.

9. Conduction Some materials allow thermal (heat) energy or electrical energy to flow through them easily. Such materials are called conductors.

10. Insulation Some materials do not allow thermal (heat) energy or electrical energy to flow through them easily. Such materials are called insulators.

11. Does it Matter? Matter has… …measurable physical properties Those properties determine… …how matter is classified, changed or used

12. EXPLAIN – Magnetism Suggested Day 2 (continued) 1. Guide class through a whole group discussion as students share data from handout: Magnetic Attraction or from their notebooks. Ask:  What type of material seemed to be attracted to a magnet? Items with iron or steel.  Were all the metals attracted to magnets? No.  Why do you think only some metals were attracted to a magnet? Allow students to explain their findings from the activity.

13. What is a property? A property describes how an object looks, feels, or acts. A property is any characteristic which can be used to describe or identify a substance.  How do properties help us identify substances? Properties are unique to matter.  What can you learn about objects by classifying them? Their identity, other substances similar to them, etc.  What does the property of magnetism show about matter? Whether or not the matter is composed of or contains iron-based metal
