WOOD HAS THE ABILITY TO BURN.
IRON HAS THE ABILITY TO RUST.

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.

3. PHYSICAL PROPERTIES WHAT DOES IT LOOK LIKE? WHAT DOES IT TASTE LIKE?
