EARTH’S PLACE IN THE UNIVERSE Construct a scientific explanation on evidence from rock strata for how the geologic time scale is used Performance Expectation to organize Earth’s geologic history. 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, Clarification Statement 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. Science & Engineering Practices Disciplinary Core Ideas Crosscutting Concepts Asking questions and defining problems THE HISTORY OF PLANET EARTH SCALE, PROPORTION, AND QUANTITY The geologic time scale interpreted from rock strata Time, space, and energy phenomena can be observed Developing and using models provides a way to organize Earth’s history. Analyses at various scales using models to study systems that Planning and carrying out investigations of rock strata and the fossil record provide only are too large or too small. relative dates, not an absolute scale.

Constructing explanations and designing (MS.ESS1C.b) solutions: 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 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.
