Physical & Chemical Changes

By Bailee Wilson

Physical Properties

Any characteristic of a material that can be observed and/or measured without changing the identity of the material


  1. Color and Shape
  2. Length and Mass
  3. Volume and Density

Physical Changes

The physical property of a substance may change, but the identity of the substance does not change.


  1. Changing From One State of Matter to the Next(Ice Melts to Liquid, Liquid Boils to Steam)
  2. Melting 0 Degrees and Boiling 100 degrees C
  3. Slicing Bread, Melting Ice, and Mowing Lawn

Chemical Properties

Any characteristic that give a substance the ability to undergo a change that results in a new substance.


  1. Flammablilty (ability to burn)
  2. Reacts with Oxygen(ability to rust)
  3. Reacts with Light(pictures being developed)
  4. Reacts with Water(medicine dissolving in water)

Chemical Change

A change in the identity of a substance due to the chemical properties of that substance


  1. Flammability(fire burning to ash)
  2. Reacts with Oxygen(fruit rotting)
  3. Heat and Light(vitamins can change exposed to light)
  4. Electricity(Water can be broken down with electricity)
