This zip file contains many different activities (48 pages of student handouts and 1 PowerPoint with a total of 49 slides) which can be used to compose a unit for chemistry students involving Solutions. Topics in this unit include saturated, unsaturated and supersaturated solutions, solubility curves, some rules involving solubility, percent of solution, molarity including calculations, parts per million calculations and colligative properties (boiling point elevation and freezing point depression with calculations).
While these lessons were originally designed to correlate to the performance indicators of the New York State Chemistry - Physical Setting curriculum, the components of this lesson may be easily used in other chemistry or physical science courses as well. The components this unit addresses in the NGSS Standards and Common Core Standards are indicated at the end of this description.
The components of this lesson package can easily be displayed to students using and LCD projector and may be readily modified into formats facilitating smartboard technology.
All documents except for the PowerPoint are included in both word docx as well as pdf format to allow editing for specific teacher needs.
The specific contents of the learning package includes the following items (the page count for these items are actual student handouts as answer key page counts are not included):
-- Marzano self assessment scale including learning goals, NGSS Standards and Common Core Reading/Writing and Mathematics Standards for students specific to this unit (3 pages)
-- Cloze notes handout for students with learning goals and Common Core Standards to accompany lesson PowerPoint (9 pages)

Students who demonstrate understanding can:
HS-PS1-5. Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
HS-PS1-6. Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.
Common Core State Standards Connections:
WHST.9-12.2 Write informative/explanatory texts, including the narration of historical events, scientific procedures/ experiments, or technical processes.
MP.2 Reason abstractly and quantitatively.
HSN-Q.A.1 Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays.
