Students who demonstrate understanding can:

Performance Expectations
 

 

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)

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)

Crosscutting Concepts

Stability and Change

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