The Standards

2nd Grade

Earth's Place in the Universe

Students who demonstrate understanding can:




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

Clarification Statement and Assessment Boundary

Clarification Statement: Examples of events and timescales could include volcanic explosions and earthquakes, which happen quickly and erosion of rocks, which occurs slowly.

Assessment Boundary: Assessment does not include quantitative measurements of timescales.

Science and Engineering Practices

Constructing Explanations and Designing Solutions

Constructing explanations and designing solutions in K–2 builds on prior experiences and progresses to the use of evidence and ideas in constructing evidence-based accounts of natural phenomenon and designing solutions.

Make observations from several sources to construct an evidence-based account for natural phenomena. (2-ESS1-1)

Crosscutting Concepts

Stability and Change

Things may change slowly or rapidly. (2-ESS1-1)
