4-ESS2-1 Earth’s Systems
Students who demonstrate understanding can: Plan and conduct investigations on the effects of water, ice, wind, and vegetation on the relative rate of weathering and erosion.
Clarification Statement: Examples of variables to test could include angle of slope in the downhill movement of water, amount of vegetation, speed of wind, relative rate of deposition, cycles of freezing and thawing of water, cycles of heating and cooling, and volume of water flow.
Assessment Boundary: Assessment is limited to a single form of weathering or erosion.
Crosscutting Concepts	Science & Engineering Practices	Disciplinary Core Ideas
Cause and Effect: Cause and effect relationships are routinely identified, tested, and used to explain change.	Planning and Carrying Out Investigations: Planning and carrying out investigations to answer questions or test solutions to problems in 3–5 builds on K–2 experiences and progresses to include investigations that control variables and provide evidence to support explanations or design solutions. With guidance, plan and conduct an investigation with peers.	Earth Materials and Systems: 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.
