Unit 1A - Matter (Gas Laws)
SPS5. Obtain, evaluate, and communicate information to compare and contrast the phases of matter as they relate to atomic and molecular motion.
a. Compare and contrast models depicting the particle arrangement and motion in solids, liquids, gases, and plasmas.
b. Plan and carry out investigations to identify the relationships among temperature, pressure, volume, and density of gases in closed systems. (emphasis should focus on the conceptual understanding of the behavior of gases rather than calculations.)

Vocabulary
Solid, liquid, gas, plasma, thermal energy, kinetic energy, temperature, freezing/melting point, boiling point, evaporation, condensation, sublimation, deposition, ionization, pressure, density, Boyle's Law and Charles' Law

Unit 1B - Solutions
SPS6. Obtain, evaluate, and communicate information to explain the properties of solutions.
a. Develop and use models to explain the properties (solute/solvent, conductivity, and concentration) of solutions.
b. Plan and carry out investigations to determine how temperature, surface area, and agitation affect the rate solutes dissolve in a specific solvent.
c. Analyze and interpret data from a solubility curve to determine the effect of temperature on solubility.
d. Obtain and communicate information to explain the relationship between the structure and properties (e.g., pH, and color change in the presence of an indicator) of acids and bases. (Clarification statement: Limited to only the structure of simple acids and bases (e.g., HCl and NaOH) that demonstrates the presence of an H+ or OH-.
e. Plan and carry out investigations to detect patterns in order to classify common household substances as acidic, basic, or neutral.
