Second Grade Next Generation Science Standards

Disciplinary Core Ideas:

ESS1.C: The History of Planet Earth - Some events happen very quickly; others occur very slowly, over a time period much longer than one can observe (2-ESS1-1).

ESS2.A: Earth Materials and Systems - Wind and water can change the shape of the land (2-ESS2-1).

Performance Expectations:

2-ESS1-1. Use information from several sources to provide evidence that Earth events can occur quickly or slowly.

2-ESS2-1. Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land.
