Unit 1A - Matter
S8P1. Obtain, evaluate, and communicate information about the structure and properties of matter.
b) Develop and use models to describe the movement of particles in solids, liquids, gases, and plasma states when thermal energy is added or removed.
c) Plan and carry out investigations to compare and contrast chemical (i.e., reactivity, combustibility) and physical (i.e., density, melting point, boiling point) properties of matter.
d) Construct an argument based on observational evidence to support the claim that when a change in a substance occurs, it can be classified as either chemical or physical. (Clarification statement: Evidence could include ability to separate mixtures, development of a gas, formation of a precipitate, change in energy, color, and/or form.)

Unit 1B - Atoms and the Periodic Table
S8P1. Obtain, evaluate, and communicate information about the structure and properties of matter.
a) Develop and use a model to compare and contrast pure substances (elements and compounds) and mixtures.
e) Develop models (e.g., atomic-level models, including drawings, and computer representations) by analyzing patterns within the periodic table that illustrate the structure, composition, and characteristics of atoms (protons, neutrons, and electrons) and simple molecules.
f) Construct an explanation based on evidence to describe conservation of matter in a chemical reaction including the resulting differences between products and reactants.
