Madras High School Unit Plan Grades: 10‐12 Subject: Chemistry Semester: 1 Unit of Study: 3: Matter‐‐‐Properties & Changes Pacing‐Teaching: Interactive Notes: 7‐10 class periods over chapter 3 Practice work assignments: 7‐10 class periods. Activities: 2 class periods. 1 in‐class activity (Lab: Chemical vs. Physical Changes) Assessments: 5 class periods (3 lab, 1 quiz, 1 unit test) Assessment Pacing: This unit takes about 3 weeks to complete. Essential Questions/Concepts: 1. What are characteristic properties of matter? 2. How are chemical properties different from physical properties? 3. How are physical changes different from chemical changes? 4. What is the Law of Conservation of Mass (what does it really mean)? 5. Contrast the differences between mixtures and pure substances. 6. What’s the difference between a homogeneous and a heterogeneous mixture? 7. How can mixtures be separated? 8. Compare and contrast mixtures, compounds and elements. 9. Describe the simplest organization of the Periodic Table. 10. Explain how all compounds obey both the Laws of Definite & Multiple Proportions. Oregon (State) Standards/Next Generation Science Standards (National)  SCI 9‐12: H2P2: Explain how chemical and physical changes demonstrate the Law of Conservation of Mass.  HS‐PS 1.7: Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.  SC.C.PM.03: Describes and provides examples of physical and chemical properties and changes. Common Core Writing Standards:  CCSS.ELA‐LITERACY.RST.9‐10.3 Follow precisely a complex multistep procedure when carrying out experiments, taking measurements, or performing technical tasks, attending to special cases or exceptions defined in the text.
