Weathering & Erosion: Our Changing Earth Fourth Grade Next Generation Science Standards include 8 different science stations where students deepen their understanding of how the weathering and erosion change the Earth’s surface. The focus is on 4-ESS1.A. Concepts include weathering, erosion, how landforms are created, rock formations, river erosion and deposition, the effect of vegetation on soil erosion, glaciers, physical and chemical weathering, and forces that cause changes on earth.
By working through this set of stations, students will gain a robust understanding of weathering and erosion and how it has changed our Earth over time. Every Station in this set meets the Crosscutting Concept: Cause and Effect. “Cause and effect relationships are routinely identified, tested, and used to explain change.” Each Station addresses how weathering and/or erosion cause the Earth to change.
In Fourth Grade, students are expected to “Make observations and/or measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation.” (4-ESS2-2). This correlates with the DCI 4-ESS2.A, which states, “Rainfall helps to shape the land and affects the types of living things found in a region. Water, ice, wind, living organisms, and gravity break rocks, soils, and sediments into smaller particles and move them around.” All stations in this set meet the DCI, helping students gain an understanding of how weathering and erosion affect the Earth. The Investigate, Diagram, Model, and Explore stations go into more detail and help students use identify cause and effect relationships, changing variables in order to go into greater depth of this.
► Vocabulary Cards
in two formats with and without pictures.
- Students watch one of two videos and then answer questions about the videos. Videos include: weathering and erosion and the formation of the Grand Canyon.
- Students play a video game and learn about the the role of weathering and erosion in creating and changing rock and land formations. Students answer questions to reinforce the new learning.
- Students read about river erosion and deposition. They will experiment with different variables affecting erosion and deposition. Students then answer questions to reinforce the concepts learned.
- Students read about the effect of vegetation on soil erosion and draw a diagram. They then answer questions in order to reinforce what they have learned.
► Read a Passage
- Students read about weathering and erosion that can be observed in many National Parks. They answer questions in order to reinforce what they have learned.
- Students read about how glaciers play a role in weathering and erosion of mountains and valleys. They answer questions in order to reinforce what they have learned.
Students read about physical and chemical weathering and explore how rocks on Earth change over time. They then answer questions about the exploration.
- Students read about forces that cause changes on Earth, such as weathering, erosion and deposition. They sort pictures into categories based on the natural forces that caused these changes. Students then answer questions in order to reinforce what they have learned.
Each station includes four different ways to respond to the experience at the station: short answer questions, fill-in the blank questions, task cards with short answers, task cards with multiple choice. All the variations are similar to one another. Choose the format that best fits your classroom and students. Students are encouraged to use their science journal, but worksheets are included as well.
Some stations include two or more activity choices and extension activities.
Each station is designed to last about 15-20 minutes. Students may do one a day for 8 days, 2 a day for four days, or any format that works for your classroom. Because there are additional activities for the Watch and Play stations, you can offer those as a choice within that station or offer them as an early finisher station, as well.
See the preview for additional information and details.
Additional Science Stations are also available.
