- Apply scientific ideas, principles, and/or evidence to provide explanations of phenomena.
- Compare and evaluate competing arguments in light of currently accepted explanations and new scientific evidence.
- Make and support a claim using empirical evidence and scientific reasoning.
- Evaluate a claim by applying scientific reasoning, theory, and/or models to link evidence to assess the extent to which reasoning and data support the explanation or conclusion.
- Evaluate the merits and limitations of models.
- Develop, revise, and/or use models based on evidence to illustrate or predict relationships, support explanations, predict phenomena, analyze systems, or solve problems.
- Use models and simulations to visualize and explain particle movement, represent chemical reactions, formulate mathematical equations, and interpret data sets.
- Apply mathematical and statistical concepts and processes in building and revising models, and supporting explanations of phenomena.
- Derive mathematical models (equations) from experimental data.
- Compare, integrate, and evaluate sources of information presented in different media or formats to address a scientific question or solve a problem.
- Gather, read, and evaluate scientific and/or technical information from multiple authoritative sources, assessing evidence and credibility.
- Communicate scientific and/or technical information about phenomena in multiple formats.
