Matter 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, odor, volume, mass, weight, and density.

Chemical Change Chemical changes are changes
matter undergoes when it becomes new or different matter.
To identify a chemical change look for signs such as color change, bubbling and fizzing, light production, smoke, and presence of heat.

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.
