Lesson Title/Focus Subject/Grade Level Ionic vs Molecular Compounds Date November 3rd, 2015 Science, Grade 9B Time Duration 90 Minutes Unit B – Matter and Chemical Change Teacher Ms. Julia Adolf OUTCOMES FROM ALBERTA PROGRAM OF STUDIES General Learning Outcomes: Specific Learning Outcomes: 9B-3. Describe ideas used in interpreting the chemical nature of matter, both in the past and present, and identify example evidence that has contributed to the development of these ideas 9B-4. Apply simplified chemical nomenclature in describing elements, compounds and chemical reactions 9B-3.4 distinguish between ionic and molecular compounds, and describe the properties of some common examples of each 9B-4.1 read and interpret chemical formulas for compounds of two elements, and give the IUPAC (International Union of Pure and Applied Chemistry) name and common name of these compounds 9B-4.2 identify/describe chemicals commonly found in the home, and write the chemical symbols LEARNING OBJECTIVES Students will: be able to distinguish between ionic and molecular compounds be able to recognize multivalent and polyatomic ions be able to describe the properties of some common examples of each be able to read and interpret chemical formulas for compounds of two elements, and give the IUPAC (International Union of Pure and Applied Chemistry) name and common name of these compounds be able to identify/describe chemicals commonly found in the home, and write the chemical symbols ASSESSMENTS Observations: Verbal Questioning and Communication Products/Performances: Analyzing Chemical Compounds Worksheet Naming Ionic Compounds Assignment LEARNING RESOURCES CONSULTED MATERIALS AND EQUIPMENT Alberta Program of Studies Computer, lab WS, quiz Chemicals, beakers, stir sticks, distilled water, conductivity meters, scoopulas PROCEDURE Prior to lesson Schedule Learning Activity #1 Print handouts and quiz, set up lab equipment Introduction 1. Review of Ions and Atoms 2. Ions and Atoms Quiz 3. Ionic vs. Molecular Properties 4. Molecular Compounds WS Body Review of Ions and Atoms Time 5 Minutes Teacher Notes: Learning Activity #2 Review how to find protons, neutrons, and electrons. Ions and Atoms Quiz 40 Minutes Teacher Notes: Students may use their own periodic tables, those to do have one give them a test table but be sure to get them back. Students have as long as they need within reason. Students may not have their phones out during this time. Learning Activity #3 Teacher Notes: Ionic vs. Molecular Properties Lab 30 Minutes Arrange the lab so that the eight different chemicals are spaced out across the room. Have the students work in groups of three. Students need to read through the lab first, and then retrieve lab coats and googles (hair tied up as well.) Students will have 5 minutes to go through the first station, cleaning their beaker and taking it with them to each subsequent one. Remind students to rinse the conductivity meters with distilled water after each test. Students then will have 3 minutes of for the remainder of the stations. Students are to clean the last station that they are at. Learning Activity #4 Molecular Compounds Worksheet Teacher Notes: Have students continue to work through their booklet completely the molecular compounds assignment. Closure: Closure Students are to complete the lab for homework. Please make sure to pay attention to the formula’s to help you figure out which compounds are ionic and which are molecular. 15 Minutes
