PROPERTIES PROPERTIES ARE CHARACTERISTICS THAT DESCRIBE AN OBJECT. THINK OF PROPERTIES AS ADJECTIVES OR DESCRIPTIONS IT LOOKS BLUE. IT SMELLS LIKE A SKUNK. WOOD HAS THE ABILITY TO BURN. IRON HAS THE ABILITY TO RUST.

CHANGES CHANGES ARE THINGS THAT CAN HAPPEN TO AN OBJECT. “HOW DID IT CHANGE??” THE WORD “CHANGE” IS A VERB...SO PHYSICAL AND CHEMICAL CHANGES ARE ALSO VERBS. I BROKE THE PENCIL IN HALF. I CUT THE ORANGE INTO PIECES. THE HOUSE BURNED DOWN. THE BICYCLE RUSTED IN THE RAIN.

PHYSICAL PROPERTIES WHAT DOES IT LOOK LIKE? WHAT DOES IT TASTE LIKE? WHAT DOES IT FEEL LIKE? WHAT DOES IT SMELL LIKE? WHAT DOES IT SOUND LIKE? MASS, WEIGHT, AND DENSITY ARE ALSO PHYSICAL PROPERTIES.

PHYSICAL CHANGES PHYSICAL CHANGES CAN BE EASILY REVERSED. IF YOU MELT A PIECE OF ICE, YOU CAN REFREEZE IT. IF YOU BOIL WATER, YOU CAN CONDENSE THE STEAM BACK INTO A LIQUID IF YOU TEAR A PIECE OF PAPER, YOU CAN TAPE IT BACK TOGETHER.

PHYSICAL CHANGES PHYSICAL CHANGES CAN BE EASILY REVERSED. TEAR A SHEET OF PAPER IN HALF CUT A PIECE OF FRUIT DISSOLVE SUGAR IN A PITCHER OF WATER CHANGING STATE VAPORIZATION CONDENSATION SUBLIMATION DEPOSITION

CHEMICAL PROPERTIES IT HAS THE ABILITY TO BURN IT HAS THE ABILITY TO RUST IT HAS THE ABILITY TO RELEASE ENERGY IT HAS THE ABILITY TO PRODUCE GAS IT HAS THE ABILITY TO CHANGE COLOR UNEXPECTEDLY IT HAS THE ABILITY TO CHANGE ODOR UNEXPECTEDLY

CHEMICAL CHANGES CHEMICAL CHANGES CAN NOT BE EASILY REVERSED. CHEMICAL CHANGES ACTUALLY SHOW THE CHEMICAL PROPERTIES. THE HOUSE BURNED DOWN. THE BICYCLE RUSTED IN THE RAIN. THE TWO CLEAR LIQUIDS TURNED PURPLE WHEN MIXED TOGETHER.

5 SIGNS OF CHEMICAL CHANGE UNEXPECTED COLOR CHANGE IODINE + STARCH = COLOR CHANGE RELEASE OF ENERGY FIREWORKS UNEXPECTED ODOR ROTTEN EGGS, SPOILED MILK PRODUCING GASES OR SOLIDS VINEGAR + BAKING SODA = GAS THE CHANGE WAS NOT EASILY REVERSED BURNED PAPER CAN'T BE CHANGED BACK INTO A SHEET OF PAPER.
