Chemistry 1 Regular Chapter 2 Section 1 Energy Bell Ringer Exercise: ATE: Pg. 38 --PowerPoint This activity has students brainstorm about energy for about five minutes. Then, students write their own definition of energy based on their brainstorming. Motivate / Review Previous Lesson: ATE: Pg. 38 --Discussion This activity has students break down where the energy needed to do activities (such as those described in the first paragraph) comes from. Introduce New Concept for Lesson: SE: Pg.37 --Start Up Activity (Lab) ATE: Pg. 39 --Reading Skill Builder Have students list things that they already know about energy and energy transfer and things they would like to know about energy, scientific methods, and measurements. District PowerPoint: “Energy” (CD) Rigor: NPR: “A 'Green' Wal-Mart in Texas” Audio file (http://www.npr.org/templates/story/story.php?storyId=4785891) Application and /or Practice of Concept: ATE: Pg. 40 --Teaching Tip To help students understand exothermic reactions, show them examples of the kinds of heat packs described in this feature. Review / Summarize: ATE: Pg. 45 --Reteaching Students create a concept map using the terms energy, physical change, chemical change, exothermic, endothermic, heat, temperature, kinetic energy, and the law of conservation of energy. ATE:Pg. 45 Quiz GENERAL: This assignment has students answer questions about the concepts in this lesson. Homework: ATE: Pg. 40 --Skill Builder Have students brainstorm words that contain therm or thermo and describe how these words relate to heat. SE: Pg. 45 --Section Review Assign items 1–13. Other Resources: ATE: Pg. 44 --Mathematics Connection Encourage students to derive the equations to convert from Celsius temperatures to Fahrenheit temperatures and vice versa.
