1 ATAMSBLAST DIGITAL AGENDA 10 – 11 College Prep Chemistry B KAUFFMAN January 2011 DO NOW: Th: With your elbow partners (groups of 3-4), brainstorm examples of colloids, suspensions, and solutions. Each group should write three examples that no one else had on the SMART™ Board. M: Solve the Exit Slip Problems on Concentrations, working with your elbow partner. Be prepared to come to the board to present your solution. California Standards: Std 6a: Solute vs Solvent Std 6c: Vars affecting rate of solution Std 6b: Solution Process Std 6d: Units of solutions Std IE: Expt & Investigation Essential Questions: What is a solution and what are the properties of solutions? How do we compare solutions? What variables affect solubility and the rate of solution? LEARNING OBJECTIVES FOR STUDENTS: Given: Compass learning activities, information and practice packet, a laboratory procedure, and direct instruction the learner will: accurately describe solutions, compare solutions and their properties, and conduct calculations related to solutions by: analyzing one solution important to their day to day lives, solving problems relative solutions using the procedures outlined in class and showing their work, and answering questions on solutions and their properties, and preparing a pre-lab for the laboratory procedure to be conducted next Monday.

2 Individual Instruction: Compass Learning: Solutions and their properties and Concept Worksheets. Assignment for Wednesday: Complete at least 25 additional vocabulary words (40 total) for the section on Solutions (already announced last week) Study for your safety quiz on Wednesday. DUE AT THE END OF CLASS THURSDAY: COMPLETE THE WORKSHEET PACKET (TWO PAGES) TITLED SOLUTION CONCEPTS HW PACKET (ON THE HW PAGE). You should also try to complete the non problem portions of the packet titled “SOLUTION CONCENTRATIONS HW” Direct Instruction: Go over last weeks quizzes Solutions and their properties Competencies on next Thursday’s test: 1c: Temperature Conversions 1e: Add/Subtract sig figs 1f: Multiply/Divide sig figs 1h: Add/Subtract in Sci Notation 2a: ID solute/solvent 2b: ID soluble, miscible, immiscible, insoluble 2c: ID heterogeneous, homogeneous, alloy, solution, colloid, suspension 2d: Classify types of matter Retakes of incorrect competencies Assignment for Monday: Worksheets on concentrations—show your work for credit (posted on HW page). Collaborative Station: As a group, work through the packet on Concentrations (posted on HW page). Each group member should identify one solution that is important in your day to day life. Then, find out what is the solvent of that solution and what are each of the solutes. How much of each is present in the solution? What role does each play in the solution? When each member has finished with their solutions, compare with your elbow partner and discuss what each of you found out. Prepare a digital presentation on your solution of importance by end of class on Monday. Monday: With your tablemates, prepare the pre-lab for your experiment on Monday. Make sure the follow the procedures outlined in the handout provided and to answer all of the questions posed. One person from each group should do the pre-lab in the group’s laboratory notebook. The others should do the pre-lab on MS Word. Make sure you assign roles for the lab on Monday. Assignment for Wednesday: Complete pre- lab

3 Classification of Matter Matter: anything that takes up space and has mass Pure substance: only one type of matter is present—it is the same throughout Element: pure substance that cannot be broken down into smaller components by non-nuclear methods Compound: composed of two or more elements in a fixed ratio and (arrangement of atoms when it is solid) Mixture: Two or more pure substances added together Homogeneous: same throughout (homogenized—grind up the solid particles into small enough parts, the milk is the same throughout) Heterogeneous: 2 different phases. Solutions: made up of a solvent and solute. The solvent is the compound that is present in the greatest amount. The solute is the compound that is present in lesser amounts. Alloys: solution made of two or more metals.

4 Classification of Matter Matter: anything that takes up space and has a resistance to a change in motion (inertia or mass) Pure substance: something that is made up of only one type of matter. Elements: smallest building blocks of matter that cannot be divided further without nuclear reactions Compound: combination of 2+ elements that are arranged in a certain order by fixed ratios. Mixture: combination of two or more pure substances that can be separated by non- chemical means. Homogeneous mixture: the same throughout (homogenized milk: chop the fat and proteins up into small particles that can be evenly dispersed in the milk. Solution: two or more compounds mixed uniformly throughout. The component in the largest amount is called the solvent. The component in the lesser amount is called the solute. Diet Pepsi: solvent: water; solutes: carbon dioxide, caramel color, aspartame, phosphoric acid, potassium benzoate, caffeine, citric acid, and natural flavors) Alloy: one or more elements or compounds dissolved in a solid metal as the solvent. Heterogeneous mixture: 2+ different regions or phases within the mixture.
