May 13, 2006 · APPENDIX F – Science and Engineering Practices in the NGSS A Science Framework for K-12 Science Education provides the blueprint for developing the Next Generation Science Standards (NGSS). The Framework expresses a vision in science education that requires students to operate at the nexus of three dimensions of learning: Science and Engineering
Science and Engineering Practices describe what scientists do to investigate the natural world and what engineers do to design and build systems. The practices better explain and extend what is meant by “inquiry” in science and the range of cognitive, social, and physical practices that it requires.
A practice of both science and engineering is to use and construct models as helpful tools for representing ideas and explanations. These tools include diagrams, drawings, physical replicas, mathematical representations, analogies, and computer simulations.
Themes. NGSS science and engineering practices (SEPs) Science and Engineering Practices: Themes. SEP.1. Asking questions and defining problems. Activity: How and why is Earth's climate changing? Activity: How do engineers design safety cushions to save lives? Activity: How do engineers design strong bridges? SEP.2. Developing and using models.
The Next Generation Science Standards, or NGSS, advocate less memorizing and more sense-making, draw connections to the Common Core, base practice in research, and apply knowledge in context.
Dimension 1: Practices. The practices describe behaviors that scientists engage in as they investigate and build models and theories about the natural world and the key set of engineering practices that engineers use as they design and build models and systems.
NGSS outlined eight science and engineering practices: Asking questions (for science) and defining problems (for engineering) Developing and using models. Planning and carrying out investigations. Analyzing and interpreting data. Using mathematics and computational thinking.
Scientific and engineering practices incorporate universal skills, such as collaboration, critical thinking, problem-solving, communication, research and meta-cognition that are commonly thought of as 21 st century process skills. Engaging students in these practices allows them to learn and demonstrate

Three Dimensions of the Next Generation Science Standards (NGSS) Scientific and Engineering Practices. Asking Questions and Defining Problems. A practice of science is to ask and refine questions that lead to descriptions and explanations of how the natural and designed world works and which can be empirically tested.
