How To Cause Physical ChangesSize
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

Chemical ChangeCauses a NEW SUBSTANCE to be
formed!New substance has NEW properties
DIFFERENT from original substance

More Signs of Chemical ReactionsChange 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 SolidPrecipitate
