Integrated Science Final Exam Review Sheet Science Department FINAL EXAM POLICY: The final exam counts as 15% of your grade. It is a comprehensive exam. The final will cover the following Chapters: Chapter 1 Chapter 2 Chapter 3 Chapter 4 Chapter 5 Chapter 8 Chapter 9 Chapter 11.1 and 11.2 Chapter 12.1 and 12.2 Chapter 16 Chapter 17 Chapter 18 Chapter 19 Introduction to Science Matter and Energy Atoms and the Periodic Table Structure of Matter Balancing Chemical Equations Motion Work and Energy Waves Light and Sound Universe Planet Earth The Atmosphere Using Natural Resources The Final is a combination of five parts. There will be multiple choice, calculations, matching, true/false, diagrams, and open-ended. You will need to bring a pencil to the exam for the scantron section and a pen for the rest of the exam. You will also need to have with you a calculator for the calculation section. Talking will not be allowed at any time during the exam. HOW TO PREPARE You should reread all the chapters and review your class notes. Study your chapter study guides. Many similar questions will come from those materials. Study the chapter review at the end of the chapters and key terms.
