Second Grade Next Generation Science Standards
Disciplinary Core Ideas:
ESS2.A: Earth Materials and Systems - Wind and water can change the shape of the land (2-ESS2-1).
ESS2.C: The Roles of Water in Earth’s Surface Processes - Water is found in the ocean, rivers, lakes, and ponds. Water exists as solid ice and in liquid form (2-ESS2-3).
Performance Expectations:
2-ESS2-1 Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land
2-ESS2-3 Obtain information to identify where water is found on Earth and that it can be solid or liquid.
