8th Grade Science Mrs. Mindy Unit 2: Earth History and Evolution Weekly Breakdown of the Unit with Goals: Week 1: The Rock Cycle 8.E.2.1: Infer the age of Earth and relative age of rocks and fossils from index fossils and ordering of rock layers (relative dating and radioactive dating). 8.L.4.1: Summarize the use of evidence drawn from geology, fossils, and comparative anatomy to form the basis for biological classification systems and the theory of evolution. Week 2: Relative and Absolute Dating: 8.E.2.1: Infer the age of Earth and relative age of rocks and fossils from index fossils and ordering of rock layers (relative dating and radioactive dating). Week 3: Layers of the Earth and Plate Tectonics: 8.L.4.1: Summarize the use of evidence drawn from geology, fossils, and comparative anatomy to form the basis for biological classification systems and the theory of evolution. Week 4: Evolution of Earth’s Land and Life Forms : 8.L.4.1: Summarize the use of evidence drawn from geology, fossils, and comparative anatomy to form the basis for biological classification systems and the theory of evolution. Week 5: Evolutionary Biology and Adaptations: 8.L.4.2: Explain the relationship between genetic variation and an organism’s ability to adapt to its environment. Week 6: Wrap up all labs and activities, test taking strategies, test review and test!!! Key Vocabulary: Inner Core Outer Core Mantle Crust Asthenosphere Tectonic Plate Continental Drift Pangaea Convection Convection Current Plate Tectonics Theory Magnetic Reversal Ice Core Geologic Time Scale Natural Selection Taxonomy Divergent Boundary Lithosphere Mid-Ocean Ridge Convergent Boundary Hot Spot Subduction Index Fossil Unicellular Organism Absolute Age Mulitcellular Organism Adaptation Speciation Six Kingdoms Relative Age Transform Boundary Fossil Original Remains Half-Life Uniformitarianism Mass Extinction Evolution Gene Classification Rift Valley Key Essential Questions: 1. What role did density have in forming the layers on the Earth? 2. How do the three main types of rocks differ in the way that they were formed? 3. How do relative and absolute dating differ? 4. How are ice cores used to tell stories of Earth’s past? 5. How are index fossils used to date rocks? 6. How is the Geologic Time Scale organized and how is the evolution of life and land described? 7. How do organisms adapt to their environment? 8. How does natural selection affect population? Unit 1 Assignment Matrix: Science How to Use this Matrix: Shaded assignments are mandatory At least 15 assignments must be completed by the end of Unit 1 The blank spaces are “student choice” assignments. This means that you can create an assignment of your choosing, but you must first submit a Proposal Form and wait for approval before you begin, so plan carefully and use your time wisely!!!
