CHEMICAL AND PHYSICAL CHANGES



Ice melting- physical change- the ice is melting into water. This is not a new substance.







Chemical reaction- fire burning- identity of the wood is changing. New substances are being formed.

















Please post your ideas for your physical change demonstration and your chemical reaction demonstration.
Make sure to include a few different ideas for each as well as a brief description of the main ones you want to use.
Last, include the materials you will need for the experiment.
