The NGSS calls for deep linkages between the three dimensions of crosscutting concepts, disciplinary core ideas, and science and engineering practices. To do this effectively, students need to gather evidence from a variety of sources, make sense of that evidence, and construct strong scientific arguments about real-world phenomena.
- Gathering evidence
In an NGSS classroom students collect evidence from a variety of sources.
- Hands-on investigations
- Physical models
- Interactive digital simulations
- Scientific texts
- Media, including video clips, photographs, maps, and data sets
- Make sense of evidence
Students make sense of evidence by:
- Highlighting and annotating texts
- Iteratively revising models
- Weighing the strength of scientific arguments
- Analyzing trends in data sets
- Manipulating variables and recording observations from digital simulations
- Discussing ideas and questions with classmates
- Construct convincing scientific arguments
Students use evidence to formulate convincing scientific arguments:
- Write a scientific argument supporting a claim using evidence they’ve collected
- Construct and revise models and write sophisticated scientific explanations
- Engage in oral argumentation in Science Seminars (grades 6-8)
- Evaluate the strengths of competing claims
