The+Rock+Cycle

__Title__: The Rock Cycle __Description__: There are three types of rock: igneous, sedimentary and metamorphic. Rocks are constantly undergoing changes because of weathering, erosion and heating. These changes allow rocks to transform from one type of rock into another type of rock. In this lesson, students will model the rock cycle using crayons. After discussing how their activity parallels the rock cycle, students will draw and label their own depiction of the rock cycle. __Duration__: 90 minutes __Learning Objectives__: Students will be able to model the steps of the rock cycle. Students will be able to draw and label the rock cycle. __Materials__: SMARTboard, laptops, crayons, plastic knives, aluminum foil, Styrofoam cup, hot water heater, blank paper, colored pencils __Step by Step Procedure__: ·  Start powerpoint presentation. ·  First slide: Introduce objective for the day by comparing the ways humans change to the ways rock change. ·  Second slide: Review rock vocabulary (metamorphic, igneous, sedimentary, erosion, weathering). Define by writing on SMARTboard. ·  Third slide: Brainstorm as a class how rocks might change over time. Write answers on SMARTboard. ·  Fourth slide: Students use laptops to use interactive rock cycle website. After students feel confident about their new knowledge teacher will review using simple depiction from slide and clarifying questions. ·  Fifth slide: Complete the crayon lab. Create mixed ability groups of students for this lab. ·  Sixth slide: Ask questions to test student understanding. Shaved crayons represent sedimentary rock. Cooled crayon is igneous rock. Heated and squished crayon is metamorphic rock. Record answers on SMARTboard. ·  Seventh slide: Students will brainstorm ways to depict the connections between different types of rock. Have volunteers show their ideas on the SMARTboard. ·  Eighth slide: Students will draw and label their own rock cycle. __Grade Level__: 7th __Support Materials__: Rock Cycle Rubric, , __Related Standards__: Key Idea MST4.PS2: Many of the phenomena that we observe on Earth involved interactions among components of air, water, and land. Performance Indicator MST4.I.PS2A: Students explain how the atmosphere (air), hydrosphere (water), and lithosphere (land) interact, evolve, and change. Performance Indicator MST4.I.PS2B: Students describe volcano and earthquake patterns, the rock cycle, and weather and climate changes. Major Understanding 2.2 g: Rocks are classified according to their method of formation. The three classes of rocks are sedimentary, metamorphic, and igneous. Most rocks show characteristics that give clues to their formation conditions.

Major Understanding 2.2h: The rock cycle model shows how types of rock or rock material may be transformed from one type of rock to another. __Submitted by__: Megan Watkins
