Physical Changes

The physical property of a substance changes but the identity of the substance stays the same.


1. Changing from one state of matter to the next. Ice melts to liquid then turns to steam.

2. Melting at 0 degrees and boiling at 100 degrees celcius.

3. Slicing bread, melting ice, mowing lawn.

2. Reacts with oxygen ( ability to rust)

3. Reacts with light ( pictures being develpoed)

4. Reacts with water( medicine dissolving in water)

Chemical Change

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


1. Flammability ( fire burning to ash)

2. Reacts with oxygen ( fruit rotting)

3. Heat and light ( vitamins can change if exposed to light)

4. Electricity ( water can be broken with electricity)
