The geologic time scale interpreted from rock strata provides a way to organize Earth’s history.Science findings are frequently revised and/or reinterpreted based on new evidence.Scientific Knowledge is Open to Revision in Light of New Evidence 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 nature operate today as they did in the past and will continue to do so in the future.(MS-ESS2-3)Ĭonstructing Explanations and Designing SolutionsĬonstructing 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. Analyze and interpret data to provide evidence for phenomena.The performance expectations above were developed using the following elements from the NRC document A Framework for K-12 Science Education:Īnalyzing data in 6–8 builds on K–5 experiences and progresses to extending quantitative analysis to investigations, distinguishing between correlation and causation, and basic statistical techniques of data and error analysis. Īnalyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of the past plate motions. Ĭonstruct an explanation based on evidence for how geoscience processes have changed Earth's surface at varying time and spatial scales. Students who demonstrate understanding can:Ĭonstruct a scientific explanation based on evidence from rock strata for how the geologic time scale is used to organize Earth's 4.6-billion-year-old history.
