Second Public Draft

Second (and Final) Public Draft is now available for review

More flexibility of viewing of the standards has been provided with two official arrangements of the performance expectations: by Topics and by Core Idea

The public feedback survey has been completed revised

Review period ends on January 29th

Final release is expected by the end of March

Conceptual Shifts in NGSS

1. K-12 Science Education Should Reflect the Interconnected Nature of Science as it is Practiced and Experienced in the Real World.

2. The Next Generation Science Standards are student performance expectations – NOT curriculum.

3. The science concepts build coherently from K-12.

4. The NGSS Focus on Deeper Understanding of Content as well as Application of Content.

5. Science and Engineering are Integrated in the NGSS from K–12.

6. The NGSS and Common Core State Standards (Mathematics and English Language Arts) are Aligned.

Inside the NGSS Box

What is AssessedA collection of several 

performance expectations describing what students 

should be able to do to master this standard

Foundation BoxThe practices, core disciplinary 

ideas, and crosscutting concepts from the Framework 

for K‐12 Science Education that were used to form the performance expectations

Connection BoxOther standards in the Next 

Generation Science Standards or in the Common Core State 

Standards that are relatedto this standard 

Performance ExpectationsA statement that combines practices, core  ideas, and crosscutting concepts together to describe how students can show what they have learned. 

Title and CodeThe titles of standard pages are not necessarily unique and may be reused at several different grade levels . The code, however, is a unique identifier for each set based on the grade level, content area, and topic it addresses.

Scientific & Engineering PracticesActivities that scientists and engineers engage in to either understand the world or solve a problem

Disciplinary Core IdeasConcepts in science and engineering that have broad importance within and across disciplines as well as relevance in people’s lives. 

Crosscutting ConceptsIdeas, such as  Patterns and Cause and Effect, which are not specific to any one discipline but cut across them all. 

Codes for Performance ExpectationsCodes designate the relevant performance expectation for an item in the foundation box and connection box. In the connections to common core, italics indicate a potential connection rather than a required prerequisite connection.

Assessment BoundaryA statement that provides guidance about the scope of the performance expectation at a particular grade level.

Clarification StatementA statement that supplies examples or additional clarification to the performance expectation.

Connections to Engineering, Technology and Applications of ScienceThese connections are drawn from the disciplinary core ideas for engineering, technology, and applications of science in the Framework.

Connections to Nature of ScienceConnections are listed in either the practices or the crosscutting connections section of the foundation box. 

Engineering Connection (*)An asterisk indicates an engineering connection in the practice, core idea or crosscutting concept that supports the performance expectation.

Closer Look at a Performance ExpectationMS-PS1 Matter and Its Interactions Students who demonstrate understanding can: MS-PS1-d. Develop molecular models of reactants and products to support the explanation that atoms,

and therefore mass, are conserved in a chemical reaction. [Clarification Statement: Models can include physical models and drawings that represent atoms rather than symbols. The focus is on law of conservation of matter.] [Assessment Boundary: The use of atomic masses is not required. Balancing symbolic equations (e.g. N2 + H2 -> NH3) is not required.]

The performance expectations above were developed using the following elements from the NRC document A Framework for K-12 Science Education:Science and Engineering Practices Disciplinary Core Ideas Crosscutting Concepts

Developing and Using Models Modeling in 6–8 builds on K–5 and progresses to developing, using and revising models to support explanations, describe, test, and predict more abstract phenomena and design systems. • Use and/or develop models to predict, describe,

support explanation, and/or collect data to test ideas about phenomena in natural or designed systems, including those representing inputs and outputs, and those at unobservable scales. (MS-PS1-a), (MS-PS1-c), (MS-PS1-d)

---------------------------------------------Connections to Nature of Science

Science Models, Laws, Mechanisms, and Theories Explain Natural Phenomena • Laws are regularities or mathematical descriptions

of natural phenomena. (MS-PS1-d)

PS1.B: Chemical Reactions • Substances react chemically in

characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants. (MS-PS1-d), ( MS-PS1-e), (MS-PS1-f)

• The total number of each type of atom is conserved, and thus the mass does not change. (MS-PS1-d)

Energy and Matter • Matter is conserved because

atoms are conserved in physical and chemical processes. (MS-PS1-d)

Note: Performance expectations combine practices, core ideas, and crosscutting concepts into a single statement of what is to be assessed. They are not instructional strategies or objectives for a lesson.

Closer Look at a Performance ExpectationMS-PS1 Matter and Its Interactions Students who demonstrate understanding can: MS-PS1-d. Develop molecular models of reactants and products to support the explanation that atoms,

and therefore mass, are conserved in a chemical reaction. [Clarification Statement: Models can include physical models and drawings that represent atoms rather than symbols. The focus is on law of conservation of matter.] [Assessment Boundary: The use of atomic masses is not required. Balancing symbolic equations (e.g. N2 + H2 -> NH3) is not required.]

The performance expectations above were developed using the following elements from the NRC document A Framework for K-12 Science Education:Science and Engineering Practices Disciplinary Core Ideas Crosscutting Concepts

Developing and Using Models Modeling in 6–8 builds on K–5 and progresses to developing, using and revising models to support explanations, describe, test, and predict more abstract phenomena and design systems. • Use and/or develop models to predict, describe,

support explanation, and/or collect data to test ideas about phenomena in natural or designed systems, including those representing inputs and outputs, and those at unobservable scales. (MS-PS1-a), (MS-PS1-c), (MS-PS1-d)

---------------------------------------------Connections to Nature of Science

Science Models, Laws, Mechanisms, and Theories Explain Natural Phenomena • Laws are regularities or mathematical descriptions

of natural phenomena. (MS-PS1-d)

PS1.B: Chemical Reactions • Substances react chemically in

characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants. (MS-PS1-d), ( MS-PS1-e), (MS-PS1-f)

• The total number of each type of atom is conserved, and thus the mass does not change. (MS-PS1-d)

Energy and Matter • Matter is conserved because

atoms are conserved in physical and chemical processes. (MS-PS1-d)

Note: Performance expectations combine practices, core ideas, and crosscutting concepts into a single statement of what is to be assessed. They are not instructional strategies or objectives for a lesson.
