MS-ESS1-4 Earth’s Place in the Universe
|
| Students who demonstrate understanding can: Construct a scientific explanation based on evidence from rock strata for how the geologic time scale is used to organize Earth’s geologic history. |
Clarification Statement: Emphasis is on analyses of rock formations and fossils they contain to establish relative ages of major events in Earth’s history. Major events could include the formation of mountain chains and ocean basins, adaptation and extinction of particular living organisms, volcanic eruptions, periods of massive glaciation, and the development of watersheds and rivers through glaciation and water erosion. The events in Earth’s history happened in the past continue today. Scientific explanations can include models.
|
Assessment Boundary: Assessment does not include recalling the names of specific periods or epochs and events within them.

Scale, Proportion, and Quantity:
- Time, space, and energy phenomena can be observed at various scales using models to study systems that are too large or too small.
|
Constructing Explanations (for science) and Designing Solutions (for engineering):
- Constructing explanations and designing solutions in 6– 8 builds on K–5 experiences and progresses to include constructing explanations and designing solutions supported by multiple sources of evidence consistent with scientific ideas, principles, and theories.
- Construct a scientific explanation based on valid and reliable evidence obtained from sources (including the students’ own experiments) and the assumption that theories and laws that describe the natural world operate today as they did in the past and will continue to do so in the future.
|
The History of Planet Earth:
- The geologic time scale interpreted from rock strata provides a way to organize Earth’s history.
- Analyses of rock strata and the fossil record provide only relative dates, not an absolute scale.
