The NGSS and

Overview of the NGSS

The Next Generation Science Standards (NGSS) focus on three main areas or dimensions that students need to understand and be able to do. They are Disciplinary Core Ideas (DCI), Science and Engineering Practices (SEP), and Crosscutting Concepts (CC).

The NGSS Standards are written as Performance Expectations (PEs) and integrate these three dimensions. These PEs are meant to guide assessment of student understanding at the end of a grade band, such as 6-8.

The NGSS sets the stage for curricula that integrates these three dimensions so that students use science or engineering practices to understand disciplinary core ideas while recognizing crosscutting concepts embedded in the lesson or unit.

Integrating SEPs, DCIs, and CCs in

In, students help design investigations to answer questions about phenomena they observe. They use molecular model illustrations, animations, and physical models to help understand and explain their observations on the molecular level. Designing investigations and developing and using models to explore and explain phenomena help students understand the nature of the science practice, the disciplinary core ideas, and the crosscutting concepts in chemistry-related physical science.

Lesson Alignments

To read about how a particular lesson addresses the Disciplinary Core Ideas, Science and Engineering Practices, and Crosscutting Concepts for an NGSS standard, simply choose the lesson to go to the NGSS alignment for that lesson.

Which Chapters Address Which Standards?

Structure and Properties of Matter

MS-PS1-1 Develop models to describe the atomic composition of simple molecules and extended structures. (Chapters 2, 3, 5)

MS-PS1-4 Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed. (Chapters 1 and 2)

MS-PS1-3 Gather and make sense of information to describe that synthetic materials come from natural resources and impact society. (Chapter 6, Lesson 12)

Chemical Reactions

MS-PS1-2 Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. (Chapter 6)

MS-PS1-5 Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved. (Chapter 6)

MS-PS1-6 Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes. (Chapter 6, Lesson 11)
