NGSS MS - PS1 - 1
Develop models to describe the atomic composition of simple molecules and extended structures.
Clarification Statement: 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 Boundary: 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.
