4th Grade (SCI) Science Standards [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
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.
-Living things affect the physical characteristics
of their regions.
