Essential Questions 1. How would you role-play the difference between ionic and covalent bonds? 2. How would you recognize ionic and covalent bonds in a list of ingredients for a product you use every day? 3. What are the similarities and differences of the different types of bonds you’ve learned? 4. How would you illustrate a covalent bond? 5. How do you write correct chemical formulas and name compounds? 6. What determines whether a bond is ionic, covalent, or metallic? Knowledge and Skills Students will know ionic bonds, covalent bonds, electronegativities, oxidation numbers and naming rules (ionic—standard; covalent—use prefixes) Students will be able to name compounds from their formulas write formulas from compound names explain the difference between types of bonds determine whether bonds are ionic or covalent given element identities (formulas or names) draw Lewis Dot diagrams Students will be familiar with hydrogen bonds, polarity, intermolecular forces. metallic bonds Z:\Chem-Phys 424\UbD\Chemical Bonding\UbD Chemical Bonding.doc 2 STAGE 2: DETERMINE ACCEPTABLE EVIDENCE What evidence will show that students understand? Required Assessments (brief description) Ionic and covalent bonding analysis Other Assessments (brief description) Create a flowchart to explain how to tell apart types of bonds Draw a picture/cartoon to illustrate a type of bond Practice worksheets for formula writing and compound naming Role-play the formation of a compound Ion Dating Game Ion Bingo Game “Come Together” internet activity Quizzes Tests Labs Activities Homework Magnesium oxide (demo or lab) Z:\Chem-Phys 424\UbD\Chemical Bonding\UbD Chemical Bonding.doc 3 PLAN LEARNING EXPERIENCES AND INSTRUCTION What sequence of teaching and learning experiences will equip students to develop and demonstrate the desired understandings? Learning Activities W How will you ensure that all students know where they are headed in the unit, why they are headed there, and how they will be evaluated? Use district reading strategies Use visual organizers (i.e., concept maps, etc.) Post unit objectives, essential questions H How will you hook students at the beginning of the unit? Ion Bingo E What events will help students experience and explore the big idea and questions in the unit? How will you equip them with needed skills and knowledge? Give students the “Ion Dating Game” to help them learn how to form ionic compounds. R How will you cause students to reflect and rethink? How will you guide them in rehearsing, revising, and refining their work? Students can work in groups to help correct each other’s mistakes and help each other learn the correct procedure. E How will you help students to exhibit and self-evaluate their growing skills, knowledge, and understanding throughout the unit? By using the activity in which students will record and classify the compounds found in products they use everyday, or a “compound scavenger hunt.” T How will you tailor and otherwise personalize the learning plan to optimize the engagement and effectiveness of ALL students, without compromising the goals of the unit? By using engaging activities (such as the scavenger hunt, role playing, etc.) that all students can be successful with. O How will you organize and sequence the learning activities to optimize the engagement and achievement of ALL students? We will begin by teaching the concept of bonding, then naming bonds and writing formulas. An optional finish is molecular geometry.

Essential Question: How would you recognize ionic and covalent bonds in a list of ingredients for a product you use every day? Vignette: You are a chemical product analyst working for the Federal Drug Administration. The FDA has recently begun to reclassify non-toxic items based upon their bonding properties. These items need to be clearly labeled as having ionic or covalent bonds. It is your job to identify the types of bonding present in a common household item, containing five or more ingredients and present your results to the president of the FDA. Standard: You will be graded with the following rubric: 5 items correctly labeled – 5 points Bring in item – 10 points Full list of ingredients – 10 points Complete data table – 20 points Identification of bond type – 10 points Z:\Chem-Phys 424\UbD\Chemical Bonding\UbD Chemical Bonding.doc Chem/Phys Chemical Bonding Performance Task Name: ____________________________ Per: _____________ Date: ___________ Name of Item: ___________________________ Ingredients: Place each ingredient name into the appropriate column below: Ionic Bonds: Covalent Bonds: Unknown: Take three (3) unknown ingredients and do some research to find out the type of bond it has: Unknown Ingredient: 1. 2. 3.
