  1. MATTER

  2. True/False Quiz • Matter must have mass • Matter must take up space • Air is matter • Matter can be in different shapes • Matter can exist in 3 states

  3. What is matter? • Anything that has massandtakes up space • Examples? • How can we describe an object made of matter?

  4. Physical Properties • Characteristics of a substance that can be observed or measuredwithout changing the substance into something else • They help usidentifydifferent types of objects • Examples?

  5. Physical Properties • Mass: amount of matter in an object • Measured in grams • Weight: measure of the pull of gravity on an object • Measured in newtons • Volume: amount of space that an object takes up • Can be measured using a graduated cylinder • Can be calculated (Length x Width x Height) • Density: the concentration of matter in an object • Can be calculated (mass ÷ volume) • Solubility: ability to be dissolved

  6. Three States of Matter • Solid: has definite shape & definite volume • Liquid: has definite volume, but no definite shape • Gas: no definite shape or volume

  7. Changes Between States • Freezing: liquid solid • Melting: solid liquid • Boiling: liquid gas

  8. Physical & Chemical Changes in Matter • Physical changes: • no new substances are formed • Changes in state • Chemical changes: • One or more new substances are formed • Also called chemical reactions *Matter is neither produced nor destroyed during these changes

  9. What’s next? • Science cards • Learning more • Experiments! • Now...it's Brain Pop time!

  10. What is Sublimation? • This is when a solid changes directly into a gas. • What? • Watch and see!
