1. Physical Science Unit Overview: Chapter 7 – Types of Matter Lesson 1 – Properties of Matter Lesson 2 – Elements Lesson 3 – Classifying Elements Lesson 4 – Mixtures Lesson 5 - Compounds Chapter 8 – Changes in Matter Lesson 1 – Chemical Reactions Lesson 2 – Metals and Alloys Lesson 3 – Salts

2. Properties of Matter Lesson Overview: 1) What do we already know? 2) Vocabulary 3) Drawings 4) Main Ideas 5) Review Types of Matter: Lesson 1

3. Page 1 Properties of Matter What do we already know?BrainPOP Teaser What is gravity? a) What keeps objects in orbit? a) 3) What causes the tides? a)

4. Page 2 Properties of Matter: Vocabulary Part I 1) volume: is the space that an object takes up -liquid volume is measured in ounces, liters, milliliters, gallons -solids are measured in cubic centimeters, cubic feet 2) mass: the amount of matter in an object (measured in grams) and isn’t changed by gravity 3) matter:anything that has mass and volume 4) weight: how strongly gravity pulls on an object (measured in pounds, ounces, kilograms) 5) State of matter: One of three forms matter can take: solid, liquid or gas Types of Matter: Lesson 1

5. Page 3 Properties of Matter: Vocabulary Part II 6) Melting point: is the temperature that solids turn into liquid 7) evaporation: is when liquids turn into gas 8) boiling point: is the temperature that liquids turn into gas 9) freezing point: is the temperature that liquids turn into solids ****the melting point and freezing point are typically the same temperature**** 10) sublimation: is when a solid turns directly into a gas 11) Density: how tightly matter is packed together Types of Matter: Lesson 1

8. Page 6 Gravity and Orbit: Drawings(pg. 346-347) Types of Matter: Lesson 1

10. Page 8 Properties of Matter: Main Ideas What is matter? (pg. 342-343) a) Anything that has mass and volume Quick Check (pg. 343) -Critical Thinking: What would be different on Saturn, your mass or your weight? a) Weight, because gravity is different on Saturn and gravity is what affects weight. Mass is not affected by gravity, therefore it does not change. Types of Matter: Lesson 1

11. Page 9 Properties of Matter: Main Ideas 2) What are the states of matter? (pg. 344-345) a) Liquid, Solid & Gas Quick Check (pg. 344) -What are the properties of each state of matter? - Liquid: Particles move more freely than in a solid, takes the shape of the container it is in and volume doesn’t change, and Particles stay relatively close together. - Solid: Particles are in an organized pattern, their shape is rigid and volume does not change, and they stay in the same place (minimal movement). - Gas: Particles move very rapidly and are widely spread out, the warmer they are the faster they move, they make their own shape when not in a container and take the shape of the container their in. Types of Matter: Lesson 1

12. Page 10 Properties of Matter: Main Ideas 3) Can the state of matter change? (pg. 346-347) Yes, matter can change when energy is added or removed. Exm: Water in liquid form turns into gas (water vapor) when energy is added and turns into a solid (ice) when energy is taken away. Quick Check (pg. 347) -Main Idea: What are the terms associated with the changes in the state of matter? a) melting point, freezing point & boiling point Types of Matter: Lesson 1
