2nd Grade (SCI) Science Standards [ESS2] Earth's Systems
SCI-02.ESS2.01 Compare and contrast multiple solutions designed to slow or prevent wind
or water from changing the shape of the land.
Clarification Statement: Examples of solutions could include different designs of dikes and windbreaks to hold back wind and
water, and different designs for using shrubs, grass, and trees to hold back the land. Disciplinary Core Ideas ESS2.A: Earth Materials and Systems
-Wind and water can change the shape of the
land.
