Title: Physical and Chemical Changes


1
Physical and Chemical Changes
  • A Write On Activity

2
Objective Chemical/Physical Change
Differentiate
  • The learner will be able to (ESSENTIAL)
    distinguish between a physical and chemical
    change.

3
Matter
  • Matter is everywhere.
  • Matter is anything that takes up space and has
    mass.
  • Matter is constantly experiencing both chemical
    and physical changes.

4
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.

Physical Change
6
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.

7
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.
