develop and critique models that describe the atomic composition of simple molecules and extended structures
analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred
gather information to describe that synthetic materials come from natural resources and impact society
develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed
develop, use, and critique a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved
