Solubility and Solutions Unit Water as the ‘universal solvent’ By: Eric Boehm Dan Wostbrock Rebecca Uduma Rui Gloria SCE 572
The New Science Frameworkand what it means • Significant changes to all disciplines • Blurring the lines between chemistry & physics • Core ideas presented to students through their academic careers • No need for course sequencing
The New Science Frameworkand what it means • Our task is to help students establish connections between the core ideas • Interwoven threads will strengthen each other and make a more lasting foundation • Add to previous knowledge, less review of previous material (more depth, less breadth)
Four Core IdeasPS1: Matter and Its Interactions • Structure and properties of matter • Chemical reactions • Nuclear processes • Underlined topics will be touched upon in the solution unit
Four Core IdeasPS2: Motion and Stability: Forces & Interactions • Forces and motion • Types of interactions • Stability and instability in physical systems
Four Core IdeasPS3: Energy • Definitions of energy • Conservation of energy & energy transfer • Relationship between energy and forces • Energy in chemical process and everyday life
Four Core IdeasPS4: Waves and Their Application in Technologies for Information Transfer • Wave properties • Electromagnetic radiation • Information technologies and instrumentation
Four Core ideas • No one course will have full ownership or responsibility for any of core ideas • Each course will be adding to these ideas • Helping students to make connections • Building upon previous work and posing new questions (mirroring the Nature of Science)
The Unit: Solutions • Solutions are not listed in the framework • The concepts within this unit are foundational skills and knowledge • This unit hits various topics throughout the framework • No dramatic changes to the lesson other than incorporating connections to previously taught material in chemistry and other classes
The Unit: SolutionsLearning Objectives and Targets • What is a solution; solvent and solute • Types of solutions • Liquid/liquid, liquid/solid, liquid/gas, gas/gas, solid/solid • Factors in solubility and rates (today’s activity) • Factors in solubility of gases: temperature & pressure
The Unit: SolutionsLearning Objectives and Targets Cont. • Solubility Curves (graph reading) • Unsaturated, saturated and super saturated • Molar concentrations and units of measurement • Dilution of a solution • New vocabulary dispersed throughout the unit
The Unit: SolutionsCalendar • Day 1 Introduction to solutions • Detergents and milk • Day 2 Inquiry Lab • Solubility factors that affect solution formation • Day 3 Solvents (polarity and water) • Day 4 Dilution of solutions lab • Day 5 Molarity of solutions
The Unit: SolutionsCalendar: continued • Day 6 Introduction to solubility curves • Demo and quiz • Day 7 Ions in solution, electrolytes • Demo / lab • Day 8 Soap and Soap article • Nonfiction reading • Day 9 Colligative properties • Day 10 Solutions test
Solutions: Interdisciplinary Connections • Biology • Dissolved gasses in the blood, digestion • ‘the bends’ for divers • Electrolytes in the body, dissolved minerals • Environmental Science • Transport of pesticides and detergent into oceans • Chemicals ‘leaching’ into water supplies (ppm of As) • Meaning of “the solution to pollution is dilution”
Solutions: Interdisciplinary Connections • Civics • EPA regulations, what are ppms and ppbs • English • Non-fiction reading • Math • Unit conversions and graph reading and interpreting
Solutions:Modifications / Differentiation / Resources • Modifications • Much of the math could be removed having more focus on the general concepts and trends • Differentiation • Unit lends itself to instruction through lecture, hands on experiments and visuals • Resources • Household materials (repeatable to sibling and parents) • Soap article and printable solubility graphs
