the fossil record shows that organisms have changed over time most fossils form when living things die and are buried by sediments, sediments slowly harden into rock and preserve the of the organism the geologic time scale interpreted from rock strata provides a way to organize Earth’s history analyses of rock strata and the fossil record provide only relative dates, not an absolute scale and meteor impacts) usually behave gradually but are punctuated by catastrophic events analyze and interpret data that include similarities of rock and fossil types on different continents, the shapes of the continents (including continental shelves), and the locations of ocean structures (such as ridges, fracture zones, and trenches) Stage 2- Assessment Evidence: Performance and other evidence: earthquake safe buildings (gummy bear challenge) Living near volcanoes engineering challenge quarterly probes Stage 3 – Learning Plan Learning Activities: model stresses, faults and plates Pangea puzzle investigate thin and thick lava flow in relation to volcanic eruptions and structures RST Notes: Indicate any special considerations as well as materials, resources (online, print, video, audio) or equipment. Course: Integrated Science Grade Level: 7 Title of Unit: Unit 4 - Earth’s Systems Stage 1 - Desired Results
Understandings: Students will understand that…….. Earth is constantly changing due to natural cycles geoscience provide resources needed by society but also cause natural hazards that present risks to society technology enables us to better understand Earth’s systems and the impact of Earth’s systems on human activity the flow of energy from the cycling of matter within and among different systems Essential Questions: How do the materials in and on Earth’s crust change over time? How does water influence and shape Earth’s surface? Knowledge: Students will know…… all Earth processes are the result of energy flowing and matter cycling within and among the planet’s system rocks are continually cycling from one kind to another due to earth's processes metamorphic rocks form from the deformation of Earth’s heat and pressure igneous rock forms from melting, cooling, and crystallization sedimentary rock forms from weathering, erosion, deposition, compaction, and cementation soil is a natural uneven distribution of resources as a result of past processes soil is one of Earth’s most valuable natural resources because everything that lives on land, including humans, depends directly or indirectly on soil soil comes from weathered rock fragments, minerals and decaying organic material soil is found in layers, each having a different chemical composition and texture water’s movements both on the land and underground cause weathering and erosion, which change the land’s surface features and create underground formations global movements of water and its changes in form are propelled by sunlight and gravity weathering, erosion and deposition act together in a cycle that wears down and builds up Earth’s surface most sediment washed or falls into a river as a result of mass movement or run-off Skills: Students will be able to….. demonstrate proficiency in developing and using models and constructing explanations develop a conceptual model the rock cycle and how it relates to the change of Earth’s surface over time develop a conceptual model the water cycle and how it relates to the change of earth's surface over time investigate weathering and erosion as processes that break down and build up Earth’s surface construct explanations based on real geoscience data explain how weathering changes the Earth’s surface over time by breaking rock into smaller pieces explain that erosion is the wearing away of the Earth’s surface by water, wind, ice and gravity debate ways that natural resources (water, soil, rocks, etc) are needed and used by society
