Physical and Chemical Changes

Matter ____________________ Matter is anything that takes up space and has mass.

Physical Change Physical changes occur when matter changes its property but not its chemical nature. ___________________________

Physical Change

Chemical Change Chemical changes are changes matter undergoes when it becomes new or different matter. _____________________________

Chemical Change A chemical change occurs when fireworks are used. Fireworks are made of metals such as magnesium and copper. These change chemically as they light up the sky.
