NGSS: K-12 Science Through Practice, Concepts and Ideas in Science & Engineering
Summary below from BozemanScience (Paul Anderson, Bozeman High School, MT) 

>>>>>>>>>>>>>>>>>      8 Practices  (SEPs)    >>>>>>>>>>>>>>>>>>
 Science-how things work/phenomenon-From InquiryEngineering-solving problems/human needs-To Design 

  1. Asking Questions (From our curiosity arises models & theories, better solutions) & Defining Problems (From questions, "What do we need? What does success look like?")
  2. Developing and Using Models-Ineffective mental models must become effective Physical, Shared, Conceptual Models, (analogs CAD software, simulations, NetLogo, vector drawings, competitions, scientific drawings, video/animation)
  3. Planning and Carrying out Investigations-Observations, Data, Watching, (Independent, Dependent, Control, Precision, Accuracy, Consistency)
  4. Analyzing and Interpreting Data-(organizing observations, science notebook, tables, graphs-line, scatter, bar, pie, causation versus correlation, statistics)
  5. Using Mathematics (quantity structure shape change) Computational Thinking (calculations using computers, NetLogo, quantities and proper units, models with simulations, spreadsheets, probes)
  6. Constructing Explanations and Designing Solutions- (theories, analogy, cycle of design, competitions, debates)
  7. Engaging in Argument from Evidence- (Informal discussion, guests, peer review, construct and critique, CER claim/evidence/reasoning)
  8. Obtaining, Evaluating and Communicating Information- (share explanations and solutions, primary literature, journals, publish information, formal communication, informal discussion (blogs, emails), science textbook, consume info and communicate what they read/understand, explicit instruction, interpret graphs, tables and figures, lab journal,


>>>>>>>>>>>      7 Crosscutting Concepts  (CCs)    >>>>>>>>>>>>>
Science-how things work/phenomenon-From InquiryEngineering-solving problems/human needs-To Design 

  1. Patterns-Initiate questions-classify data points or phenomenon, pattern recognition, product testing, evaluate patterns ie, Sun, Moon Earth relationships, fossil record, wave patterns, DNA, properties of matter, rate of change)
  2. Cause and Effect:Mechanisms and Explanation-causal or correlational, use relationships to make predictions, probability)
  3. Scale, Proportion and Quantity- time, space, energy, speed, algebraic expressions, equations, proportional relationships)
  4. System and System Models  -systems with or without sub-systems or complexity, input-output models, flow charts, limitations of models
  5. Energy and Matter: Flows, Cycles and Conservation- conservation in physical and chemical processes, energy transfer drives cycles, forms of energy, tracking energy flows 
  6. Structure and Function -complex structures of all sizes can be represented and used to study function and relationships, properties, and the uses of materials
  7. Stability and Change -parts of whole, synergy, equilibrium, feedback mechanisms, chain reactions, rates of change, constants
