Chemistry – College PrepItalics reflect 21 st Century Skills implementationCourse Title: ChemistryUnit Title: SolutionsContent Standards:Scientific Inquiry, Literacy and NumeracyScientific inquiry is a thoughtful and coordinated attempt to search out, describe, explain and predictnatural phenomena.Scientific inquiry progresses through a continuous process of questioning, data collection, analysis andinterpretation.Scientific literacy includes the ability to read, write, discuss and present coherent ideas about science.Scientific literacy also includes the ability to search for and assess the relevance and credibility ofscientific information found in various print and electronic media.Scientific numeracy includes the ability to use mathematical operations and procedures to calculate,analyze and present scientific data and ideas.Haddam Killingworth High School Expectations for Student LearningThe Haddam Killingworth graduate will problem solveThe Haddam Killingworth graduate will access and analyze information.Enduring Understandings:Solubility is determined by intermolecular bonding (or the lack thereof) not densitySolubility is affected by temperature and pressureConcentration can be specified by a solution’s molarity.Essential Question(s)What determines if a chemical is soluble in water or another solvent?What factors influence solubility?How is the concentration of a solution specified?Students will know . . . .“Likes dissolve likes”Various factors that contribute to a solutionprocess being exo- or endothermicConcentration calculationsPerformance Tasks/Product(s):Introductory solutions labPreparation of a specific concentration labStudents will be able to . . . .Draw pictures of various solutions(nonelectrolyte, weak electrolyte, strongelectrolyte)Write chemical equations that show thevarious solutions (nonelectrolyte, weakelectrolyte, strong electrolyte)Explain temperature effects of solutions interms of lattice energy, solvent separations,solvent/solute interactionsCalculate solute concentrations, ionconcentrations, and amounts of solutesKey Evaluation Criteria/Rubric Titles:Can solutions be calculated and physically prepared in an accurate manner?Can two chemicals be correctly identified as dissolving in each other or not?Revised 2009Contributor: Jim DanielsProperty of RSD #1726
