[ESS2] Earth's Systems

SCI-04.ESS2.01 Make observations and metric measurements to provide evidence of the effects of weathering and the rate of erosion by water, ice, wind, or vegetation.

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.
Disciplinary Core Ideas
ESS2.A: 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.
ESS2.E: Biogeology -Living things affect the physical characteristics of their regions.
