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.
Knowledge Targets:
LK12-1 I can define solution, solute and solvent.
LK12-2 I can define concentration in terms of solute per unit solvent (i.e. dilute, concentrated, saturated, unsaturated, super-saturated).
LK12-3 I can recognize that when placed in a solution, solutes will affect the conductivity of that solution.
LK12-4 I can recognize the factors that affect the solubility rate of a solute within a solution.
LK12-5 I can explain the purpose of a solubility curve.
LK12-6 I can list properties of acids, bases, and neutral substances.
LK12-7 I can describe the role of an indicator in classifying substances as acids, bases, or neutral.

Reasoning Targets:
LR12-1 I can compare and contrast solutes, solvents and solutions.
LR12-2 I can differentiate between a solute and a solvent within a solution.
LK12-3 I can use a solubility curve/table to interpret information regarding solubility and temperature of solutions.
LR12-4 I can explain how temperature, surface area, and agitation affect the rate solutes dissolve in a specific solvent.
LR12-5 I can compare the solubility of different solutions.
LR12-6 I can compare the pH level of acids and bases.
LR12-7 I can classify acids and bases as strong or weak depending on their location on the pH scale.
