7.2: Changes to Earth 3 Dimensions & Progressions

Unit 3

matter cycling that create igneous, sedimentary, and metamorphic rocks. Emphasize the processes of melting, crystallization, weathering, deposition, sedimentation, and deformation, which act together to form minerals and rocks. (MS-ESS2-1)

CONCEPTS

SKILLS

●​ Rock Cycle ●​ Relationship between energy flow and cycling of matter ●​ Creation of different types of rocks ●​ Weathering and erosion ●​ Mineral formation

●​ Develop a model

LEARNING PROGRESSIONS

●​ Earth’s processes are a results of energy flowing and matter cycling ●​ Energy for the rock cycle comes from Earth’s hot interior and from the Sun. ●​ Cycling of matter occurs because of chemical and physical changes. ●​ Changes lead to mineral formation ●​ Cycling of matter has shaped Earth’s history

VOCABULARY

●​ Matter Cycling ●​ Energy Flow ●​ Igneous ●​ Sedimentary ●​ Metamorphic ●​ Melting

●​ Crystallization ●​ Weathering ●​ Erosion ●​ Sedimentation

●​ Deposition ●​ Minerals ●​ Heat Energy ●​ Atmosphere

POSSIBLE PHENOMENA ●​ A clay flower pot left out over the winter breaks into small pieces. ●​ Photographs of specific Hoodoos in Bryce National Park in Utah show significant changes in the size of these formations over the past 100 years. ●​ Large arches in rock formations can be seen in Arches National Park in Utah. ●​ Not all rocks weather at the same rate. ●​ The rocks in Farmington Canyon have unusual “ribbons” or bands. ●​ There are big HUGE boulders scattered all over the mouth of Little Cottonwood Canyon. END OF UNIT COMPETENCY WITH LANGUAGE SUPPORTS ●​ I can use a rock cycle model to describe the relationship between energy flow and matter cycling on Earth. ○​ Language Supports ■​ Nouns to support claim (cycling, energy, weather, rain, snow, wind) ■​ Connectors to link clauses (as a result of, therefore, to be more precise, instead,
