2. Notes: Props of Matter TALK Matter: is anything that has mass and takes up space (has volume) and can exist as a solid, liquid, gas, or plasma All matter is made up of atoms. Matter can be identified by physical properties such as odor, volume, density, color, malleability, etc Matter can be also be identified by chemical properties such as, reactivity and flammability (See Holt Online Ch7/Sect 3 VC about Phys. & Chem Props) 4 SPI 0807.9.8 Physical & Chemical Changes

3. Notes: Props of Matter TALK Physical Changes: changes the appearance of an object, but does not actually change the composition of the object  Physical Changes Do Not Form New Substances  Examples of Physical Changes Two examples are shown below. 5 SPI 0807.9.8 Physical & Chemical Changes

4. Notes: Props of Matter TALK Chemical Changes: occur when a substance, due to a chemical reaction, is changed into a new substance.  Indicators of chemical changes include a change in odor, heat given off, explosions, fizzing, foaming, and/or sound or light given off (See Holt Online Ch7/Sect 3 VC about Phys. & Chem.
