Unit 7 Lesson 1 What Are Physical Properties of Matter? Use Your Senses Matter • A characteristic of matter that you can observe or measure directly is a physical property. • You can use your senses to make physical observations like, hearing, tasting, smelling, touching, and seeing. • Copyright © Houghton Mifflin Harcourt Publishing Company

Unit 7 Lesson 1 What Are Physical Properties of Matter? Matter • The amount of matter in an object is its mass. You can use a pan balance to measure mass. Copyright © Houghton Mifflin Harcourt Publishing Company

Unit 7 Lesson 1 What Are Physical Properties of Matter? Matter • Less massive objects are measured in grams (g). More massive objects are measured in kilograms (kg). Copyright © Houghton Mifflin Harcourt Publishing Company

Unit 7 Lesson 1 What Are Physical Properties of Matter? Describe That! • Matter can be described in many ways. • It can be described by hardness, or how easily something can bend or dent. Copyright © Houghton Mifflin Harcourt Publishing Company

Unit 7 Lesson 1 What Are Physical Properties of Matter? Describe That! • Matter also can be described by size, taste, and color, or how light bounces off an object. Copyright © Houghton Mifflin Harcourt Publishing Company

Unit 7 Lesson 1 What Are Physical Properties of Matter? Describe That! • Matter can be described by texture, or what something feels like. • Matter also can be described by odor and shape, or by an object’s form. Copyright © Houghton Mifflin Harcourt Publishing Company

Unit 7 Lesson 1 What Are Physical Properties of Matter? Pump Up the Volume! • Volume is how much space an object takes up. Volume is measured in milliliters (m. L). • The beaker can be used to measure the volume of liquids. Copyright © Houghton Mifflin Harcourt Publishing Company

Unit 7 Lesson 1 What Are Physical Properties of Matter? Don’t Be So Dense! • Density is a physical property of matter. It is the amount of matter present in a certain volume of a substance. Copyright © Houghton Mifflin Harcourt Publishing Company

Unit 7 Lesson 1 What Are Physical Properties of Matter? Don’t Be So Dense! • Density indicates how close together the particles in an object are. • The density of a substance does not depend on how much matter is present. • A small piece of eraser has the same density as a whole eraser.
