Standards

Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. Examples of reactions could include burning sugar or steel wool, fat reacting with sodium hydroxide, and mixing zinc with hydrogen chloride. Assessment is limited to analysis of the following properties: density, melting point, boiling point, solubility, flammability, and odor.

Develop models to describe the atomic composition of simple molecules and extended structures. Emphasis is on developing models of molecules that vary in complexity. Examples of simple molecules could include ammonia and methanol. Examples of extended structures could include sodium chloride or diamonds. Examples of molecular-level models could include drawings, 3D ball and stick structures, or computer representations showing different molecules with different types of atoms. Assessment does not include valence electrons and bonding energy, discussing the ionic nature of subunits of complex structures, or a complete depiction of all individual atoms in a complex molecule or extended structure.
