  1. Physical Properties A property than can be observed, measured, or changed without changing the substance itself

  2. Magnetism • Matter that contains iron or nickel will be attracted to a magnet. • Not all metals are attracted to a magnet.

  3. Physical State • Three forms: liquid, solid, or gas • Can change from one form to another by the processes of melting, freezing, evaporation, and condensation • Temperature changes are involved with changes in state.

  4. Mass • Mass is the amount of matter in an object. Mass is measured with a balance. • Mass is not the same as weight. • Weight is a result of the pull of gravity on an object and is measured with a scale.

  5. Buoyancy Floating • The upward push of a liquid or gas on an object.

  6. Relative DensitySinking & Floating • Weight doesn’t determine if an object will sink or float. • The volume of an object and how much “stuff” (matter) is in the object will determine the density.

  7. Solubility in Water • Ability of a substance to dissolve when added to water • A liquid, solid, or gas can be dissolved in water. Examples may include lemon juice in water, sugar in tea, and the carbonation in a soda.

  8. Conduction • Some materials allow thermal (heat) or electrical energy to flow through them easily. • These materials are called conductors.

  9. Insulation • Some materials do not allow thermal (heat) energy or electrical energy to flow through them easily. • These materials are called insulators.

  10. Does it Matter? • Matter has properties that can be observed and measured. • These properties determinehow matter is • classified • changed • or used
