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

3. 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.

5. 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.

6. 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.
