3. Properties of Matter What do we already know? BrainPOP Teaser BrainPOP Teaser 1)What is gravity? a) 2)What keeps objects in orbit? a) 3) What causes the tides? a) Page 1

4. 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 Page 2 Types of Matter: Lesson 1

5. 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 Page 3 Types of Matter: Lesson 1

10. Properties of Matter: Main Ideas 1)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. Page 8 Types of Matter: Lesson 1

11. 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.

12. 3) Can the state of matter change? (pg. 346-347)  a)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 Page 10 Properties of Matter: Main Ideas Types of Matter: Lesson 1
