Big Idea 6: Earth Structures Weathering and Erosion Topic XIV What are the basic differences between physical weathering and erosion? Open up Discovery Education from your Employee Portal and minimize.

Florida Standards (formerly Common Core) Integration Benchmark Focus Science SC.4.E.6.4 Describe the basic differences between physical weathering (breaking down of rock by wind, water, ice, temperature change, and plants) and erosion (movement of rock by gravity, wind, water, and ice). Florida Standards (formerly Common Core) Integration LAFS.5.W.3.9: Draw evidence from literary or informational texts to support analysis, reflection, and research. LAFS.5.SL.1.1: Engage effectively in a range of collaborative discussions (one-on-one, in groups, and teacher-led) with diverse partners on grade 5 topics and texts, building on others’ ideas and expressing their own clearly. LAFS.K12.L.3.4 : Determine or clarify the meaning of unknown and multiple-meaning words and phrases by using context clues, analyzing meaningful word parts, and consulting general and specialized reference materials, as appropriate.

What role do rocks and water have in the process of weathering minerals? Hypothesis: Explore: See Gr. 4 Scott Foresman p. 260 TE

What role do rocks and water have in the process of weathering minerals? Data Before the experiment Length of chalk _____ cm Other observations: Chalk Looks: Chalk feels After the experiment Length of chalk _____ cm Other observations: Chalk Looks: Chalk feels Explore: See Gr. 4 Scott Foresman p. 260 Procedures: 1. Students make a two column chart in their in their notebook and label it like the slide. Pass out a piece of chalk per group for students to examine, measure length and record their observations using sight and touch in the first column, titled Before Shaking the Jar (control) After the students have completed the experiment, they will measure the length and observe the chalk again.

What role do rocks and water have in the process of weathering minerals? Procedure: Explore: See Te Gr. 4 Scott Foresman p. 260 to direct students completing the experiment.

What are 5 types of PhysicalWeathering? wind, water, ice, temperature change, and plants Match to the pictures below: 1. 3. 2. Explore and Explain: Click on the discovery Ed. hyperlink: PhysicalWeathering video. View and discuss. Read in SF gr. 4 pp. 263-264. Review weathering by watching the hyperlinked video and/or Evaluate: Have students number a paper in their notebook and identify the 4 types of weathering shown in the pictures. Wind rain Ice Plant roots Have students write a definition and place in their notebook using the Frayer model. See the next slide. Note: students do not have to know chemical weathering. 4.

Department of Mathematics and Science Explore/Explain/Evaluate: Have students create a definition using the Frayer model in their notebook. Department of Mathematics and Science

What is Erosion? Erosion is the movement of sediments from one place to another. Water is the primary agent of erosion, though wind and glacier ice also contribute . Create a definition of erosion In your notebook. Explore and Explain: Review erosion by playing the hyperlink: What is Erosion? Have students discuss. Open the link Erosion and   click each dot on the map of North America to see a photograph showing the effects of erosion. Read and discuss SF gr. 4 pp. 266-268. Have students create a definition using the Frayer model in their notebook. Evaluation: Ask: What part do weathering and erosion play in the formation of sedimentary rocks? Weathering and erosion create the small rock particles that, along with organic matter, make up soils. The same small rock particles can be transported by water and find their way to the bottom of lakes and oceans where they form layers. As more and more layers are deposited, the pressure from the weight above and consolidation of the minerals and the particles may cause them to cement together, creating a sedimentary rock.

What are the four agents of Erosion? gravity wind water ice Create a definition of erosion in your notebook.

Let’s do DE Exploration: Erosion and Deposition Create the table below in your notebook. Explore: click on the link Erosion and Deposition to open the DE Exploration.

What is the difference between Weathering and Erosion? Weathering is the breaking down of rock into tiny pieces Five processes of weathering: Wind Water Ice Plants Temperature change Erosion is the movement of weathered rock (sediment) Four agents of erosion Wind Water Ice gravity Explain and Evaluate: Ask: What is the difference between Weathering and Erosion? Discuss. Then click on the hyperlink: Weathering and Erosion Click on click on the hyperlink: Weathering Have students define it. Then name the five processes of weathering. Give examples. Next click on the hyperlink: Erosion Have students define it. Then name the four agents. Give examples. Students can create a foldable naming the five processes of weathering and creating drawing/pictures for each. Students can create a foldable naming the four agents of erosion and creating drawing/pictures for each.
