Scientific and Engineering Practices

Virginia SOL AP.1

Demonstrate understanding of scientific and engineering practices through investigation, analysis, and communication.

What students need to be able to do

  • Ask questions that arise from careful observation of phenomena, organisms, models, or theories to seek additional information.
  • Determine which questions can be investigated within the scope of a school laboratory or field setting.
  • Formulate hypotheses specifying the relationship between independent and dependent variables.
  • Generate hypotheses based on research and scientific principles.
  • Plan and conduct observational and experimental investigations; identify variables, constants, and controls.
  • Plan and conduct investigations in a safe and ethical manner, considering environmental, social, and personal effects.
  • Determine appropriate sample size and techniques for investigations.
  • Select and use appropriate tools and technology to collect and record data.
  • Construct and interpret data tables showing independent and dependent variables, repeated trials, and means.
  • Construct, analyze, and interpret graphical displays of data; consider limitations of data analysis.
  • Use data to build and revise models, support explanations for phenomena, or test solutions to problems.
  • Apply mathematical concepts and processes in scientific investigations.
  • Analyze data using tools, technologies, and/or models to make valid and reliable scientific claims.
  • Construct and revise explanations based on valid and reliable evidence from models, theories, simulations, peer review, or investigations.
  • Make quantitative and/or qualitative claims based on data.
  • 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 the 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.
  • Apply mathematical and statistical concepts and processes in building and revising models, and supporting explanations of phenomena.
  • 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 the evidence and credibility of each source.
  • Communicate scientific and/or technical information about phenomena in multiple formats.
