Matter Review Matter is everywhere. Matter is anything that takes up
space and has mass. Matter is constantly experiencing
both chemical and physical changes.

Physical Change Physical changes occur when
matter changes its property but not its chemical nature.
Physical property changes could include a change in: texture, shape, size, color, volume, mass, weight, and state (melting, boiling, freezing).

Physical Property Changes Texture
Ex: A piece of wood that has been sanded with sandpaper.
It is still wood, only the texture has been changed.

Chemical Change Chemical changes are changes matter
undergoes when it becomes new or different matter.
Most of the time, the matter cannot go back to the original substance.
To identify a chemical change look for signs such as color change, bubbling and fizzing, light production, smoke, rusting or tarnishing.

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.
