  1. Physical and Chemical Changes

  2. Physical Change • Anything that changes the physical properties of a substance • Size • Shape • Texture • Color** • Luster • Phases/States • ETC

  3. How To Cause Physical Changes • Size • Cutting • Breaking • Stretching • Shape • Cutting • Sanding • Breaking • Texture • Sanding • Scratching • Color** • Painting • Coloring with Markers • Luster • Sanding • Phases • Any Phase Change • Mixing • Taking two Substances and Mixing them Together

  4. Chemical Change • Causes a NEW SUBSTANCE to be formed! • New substance has NEW properties DIFFERENT from original substance

  5. Signs of a Chemical Change • Energy Released • Heat • Light • Sound • UV / Microwaves / Radiation / Gamma Rays / ETC • Formation of a Gas • Bubbles • Foam • Color Change ** • “Rusting” • Bleaching • Rotting

  6. More Signs of Chemical Reactions • Change in Temperature • Exothermic Reaction • To GIVE OFF heat • Substance gets WARM or HOT (Increase in Temperature) • Endothermic Reaction • To TAKE IN heat • Substance gets COOL or COLD (Decrease in Temperature) • Formation of a Solid • Precipitate
