Submit a picture of YOUR diagram colored in like the one in this picture.
Something is probably a physical change if you can undo it (like gluing together a broken plate, or melting some water that has frozen).
Sugar is burned and melted into carmel
You drop a glass of water and it breaks
You break a glowstick and begins to glow or light up
A piece of wood burns in a camp fire
A puddle evaporates
A pond freezes on a cold night
An ice cube is left out in the sun and melts
Mentos are added to diet coke producing a lot of bubbles
You break room temperature ice pack, and suddenly the gel in the ice pack gets very, very cold
