# Earth's Systems

### Students who demonstrate understanding can:

#### Performance Expectations

1. Make observations and/or measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation.

Clarification Statement and Assessment Boundary

A Peformance Expectation (PE) is what a student should be able to do to show mastery of a concept. Some PEs include a Clarification Statement and/or an Assessment Boundary. These can be found by clicking the PE for "More Info." By hovering over a PE, its corresponding pieces from the Science and Engineering Practices, Disciplinary Core Ideas, and Crosscutting Concepts will be highlighted.

### Science and Engineering Practices

#### Planning and Carrying Out Investigations

Planning and carrying out investigations to answer questions or test solutions to problems in 3â5 builds on Kâ2 experiences and progresses to include investigations that control variables and provide evidence to support explanations or design solutions.

By clicking on a specific Science and Engineering Practice, Disciplinary Core Idea, or Crosscutting Concept, you can find out more information on it. By hovering over one you can find its corresponding elements in the PEs.

## Planning Curriculum

### Common Core State Standards Connections

#### ELA/Literacy

• W.4.8 - Recall relevant information from experiences or gather relevant information from print and digital sources; take notes and categorize information, and provide a list of sources. (4-ESS2-1)

#### Mathematics

• 4.MD.A.1 - Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two column table. (4-ESS2-1)
• 4.MD.A.2 - Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale. (4-ESS2-1)
• MP.2 - Reason abstractly and quantitatively. (4-ESS2-1)
• MP.4 - Model with mathematics. (4-ESS2-1)
• MP.5 - Use appropriate tools strategically. (4-ESS2-1)

## Resources & Lesson Plans

• More resources added each week!
A team of teacher curators is working to find, review, and vet online resources that support the standards. Check back often, as NSTA continues to add more targeted resources.
•   This nonfiction informational text describes and illustrates the geological history of the Grand Canyon. The effects of weathering and subsequent erosion are detailed in descriptions of the rock layer formations. Evidence of landscape chang ...

• This National Park lesson plan focuses on the destructive forces of nature in Yellowstone National Park, but student investigations can be adapted to any landscape. Students work in groups to create a landscape (a model of a small mountain) from a va ...

• This lesson is one of a series involving the geology of Grand Canyon National Park. Students are asked to make a model of the phenomenon of erosion as it relates to the landscape formation of the Grand Canyon. Students use a milk carton designed to a ...

• This lesson is part of a Grade 4 Unit on Weathering and Erosion. Students discuss landform changes, then create and demonstrate several weathering and erosion models, focusing on wind, water, ice, and chemical influences. Students are given oppo ...

• Students contemplate the big idea that erosion affects the surface of the earth's crust. The teacher creates student interest with an anchoring event called RAP- Review and Preview. Focus and relevance for the lesson is emphasized by asking stude ...

• Students aim to make sense of glacial phenomenon through observation and analysis of a mini glacier simulation in the classroom. Prior knowledge can be elicited from the short video clip of a "glacier calving", before engagin ...

• This resource includes a three-dimensional weathering lesson embedded in an article describing strategies for whiteboard use in the classroom. Students engage in a group/class discussion as they explain how rocks change over timeb ...

• This set of 31 Weathering and Erosion slides depict landform changes that occur due to the natural processes of weathering and erosion. Captions explain/define the different causes of weathering and erosion (ice, wind, water, and vegetation ...

• This article and associated formative assessment probe can be used to determine students' prior knowledge and misconceptions about weathering and erosion. Implemented before or during a weathering/erosion unit, ...

• This science lesson integrates the concepts of physical weathering and erosion with an English/Language Arts informational text lesson. Students are guided through a reading of a National Geographic encyclopedic article, as the teacher provides close ...

• This engineering design lesson focuses on the effects of erosion on Florida's coastline. It is one lesson offered within a larger weathering and erosion unit. Students groups work to create and use a model able to slow erosion, without damaging t ...

• Fourth grade lessons on glacial erosion demonstrate and explain the manner in which glaciers erode the earth. The mechanisms of plucking and abrasion are discussed. Activities (either whole-class or small group) include a teacher creation of a glacie ...

• This book allows students to observe illustrations of magnified sand particles with guided dialogue from an earth scientist who discusses sand origins. This book can be used to introduce students to types of sand, explain how earth processes were re ...

• Bill Nye, "The Science Guy", presents a video describing the effects of weathering (wind, water, ice) on landforms. Bryce Canyon is used as an example of the ways in which freezing water, plant roots, and wind weather the earth's surfac ...

• This hands-on activity allows students to explore five earth forces that may cause erosion as they model, observe, and record the effects of erosion on earth surfaces. Stations include demonstrations of chemical, wind, water, ice and heat forces as t ...
