Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.
STRATA SCALE WINDOWS
Use variables to represent numbers and write expressions when solving a real-world or mathematical problem understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.

Write informative/explanatory texts to examine a topic and convey ideas, concepts, and information through the selection, organization, and analysis of relevant content. Time, space, and energy phenomena can be observed at various scales using models to study systems that are too large or too small.Ĭonnections to other DCIs in this grade-band:ģ.LS4.A 3.LS4.C 3.LS4.D 4.ESS1.C HS.PS1.C HS.LS4.A HS.LS4.C HS.ESS1.C HS.ESS2.AĬite specific textual evidence to support analysis of science and technical texts.Analyses of rock strata and the fossil record provide only relative dates, not an absolute scale. million of capital to help fund development, construction and ownership of utility scale solar and storage assets across North America. The geologic time scale interpreted from rock strata provides a way to organize Earth’s history.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 performance expectation above was developed using the following elements from the NRC document A Framework for K-12 Science Education: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. 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.
