MATTER and CHEMISTRY
Standards:
6.P.2: Understand the structures, classifications and physical properties of matter.
6.P.2.1: Recognize that all matter is made up of atoms and atoms of the same element are all alike, but are different from the atoms of other elements.
6.P.2.2: Explain the effect of heat on the motion of atoms through a description of what happens to particles during a change in phase.
6.P.2.3: Compare the physical properties of pure substances that are independent of the amount of matter present including density, melting point, boiling point and solubility to properties that are dependent on the amount of matter present to include volume, mass and weight.

Students, by the end of the unit, will know and understand that:
* Physical properties are different for each element.
* Whenever substances change phases, the speed of their particles are impacted.
* Matter is made of atoms. Atoms in substances are always in motion and atoms of the same element are alike.
* Heat impacts the speed of the motion of atoms.
* Physical properties of substances can be used to identify them and substances can go through a change of phase or a phase change (solid, liquid, gas, plasma).
* The amount of matter present will affect the volume, mass, and weight of a substance.
* The amount of matter present will not affect the density, melting point, boiling point, or solubility of a substance.
* Elements are pure substances.
* Physical properties are density, melting point, boiling point, solubility, volume, mass, and weight.
* Volume, mass and weight are dependent upon the amount of matter present.
