Scientific and Engineering Practices
Virginia SOL ENV.1
Demonstrate understanding of scientific and engineering practices through investigation, analysis, and communication.
What students need to be able to do
- Ask questions arising from observation of phenomena, models, theories, or to seek additional information.
- Determine which questions can be investigated within the scope of a school laboratory or field study.
- Formulate hypotheses specifying the relationship between independent and dependent variables.
- Generate hypotheses based on research and scientific principles.
- Define design problems involving processes or systems with multiple components and criteria.
- Plan and conduct observational and experimental investigations; identify variables, constants, and controls.
- Conduct investigations or test design solutions safely and ethically, considering environmental, social, and personal effects.
- Select and use appropriate tools and technology to collect and record data.
- Determine appropriate sample size and techniques for investigations.
- 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 to analyze data.
- Analyze data using tools, technologies, and/or models to make valid and reliable scientific claims or determine optimal design solutions.
- 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 explain phenomena or design solutions.
- Compare and evaluate competing arguments or design solutions using accepted explanations and new scientific evidence.
- Make and support claims using empirical evidence and scientific reasoning.
- Evaluate claims by applying scientific reasoning, theory, and/or models to link evidence to explanations or conclusions.
- Differentiate among scientific hypothesis, theory, and law.
- 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.
- Compare, integrate, and evaluate sources of information presented in different media or formats to address scientific questions or solve problems.
- 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 or design processes in multiple formats.
