Framework

The National Research Council
(NRC) of the National Academy of
Sciences managed the first of two
steps in the creation of the Next
Generation Science Standards by
developing the A Framework for K12 Science Education, which was
released July 2011.

Three Dimensions

The National Research
Council's (NRC) Framework
describes a vision of what it
means to be proficient in
science; it rests on a view of
science as both a body of
knowledge and an evidencebased, model and theory
building enterprise that
continually extends, refines,
and revises knowledge.
+
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.

The NRC uses the term practices instead of a term like
“skills” to emphasize that engaging in scientific investigation
requires not only skill but also knowledge that is specific to
each practice.
+
Crosscutting Concepts

Crosscutting concepts have application across all domains of
science. As such, they are a way of linking the different
domains of science.
+
Disciplinary Core Ideas

Disciplinary core ideas have the power to focus K–12 science
curriculum, instruction and assessments on the most
important aspects of science.

Disciplinary ideas are grouped in four domains: the physical
sciences; the life sciences; the earth and space sciences;
and engineering, technology and applications of science.

Core Idea PS1: Matter and Its Interactions

PS1.A: Structure and Properties of Matter

2-PS1-1: Different kinds of matter exist and many of them can be either solid or liquid, depending on temperature. Matter can be described
and classified by its observable properties.

2-PS1-2, 2-PS1-3: Different properties are suited to different purposes.

2-PS1-3: A great variety of objects can be built up from a small set of pieces.

5-PS1-1: Matter of any type can be subdivided into particles that are too small to see, but even then the matter still exists and can be detected
by other means. A model showing that gases are made from matter particles that are too small to see and are moving freely around in space
can explain many observations, including the inflation and shape of a balloon and the effects of air on larger particles or objects.

5-PS1-2: The amount (weight) of matter is conserved when it changes form, even in transitions in which it seems to vanish.

5-PS1-3: Measurements of a variety of properties can be used to identify materials. (Boundary: At this grade level, mass and weight are not
distinguished, and no attempt is made to define the unseen particles or explain the atomic-scale mechanism of evaporation and condensation.)

MS-PS1-1: Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that
range in size from two to thousands of atoms.

MS-PS1-2, MS-PS1-3: Each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions)
that can be used to identify it.

MS-PS1-4: Gases and liquids are made of molecules or inert atoms that are moving about relative to each other.

MS-PS1-4: In a liquid, the molecules are constantly in contact with others; in a gas, they are widely spaced except when they happen to collide.
In a solid, atoms are closely spaced and may vibrate in position but do not change relative locations.

MS-PS1-1: Solids may be formed from molecules, or they may be extended structures with repeating subunits (e.g., crystals).

MS-PS1-4: The changes of state that occur with variations in temperature or pressure can be described and predicted using these models of
matter.

HS-PS1-1: Each atom has a charged substructure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons.

HS-PS1-1, HS-PS1-2: The periodic table orders elements horizontally by the number of protons in the atom’s nucleus and places those with
similar chemical properties in columns. The repeating patterns of this table reflect patterns of outer electron states.

HS-PS1-3, HS-PS2-6: The structure and interactions of matter at the bulk scale are determined by electrical forces within and between atoms.

HS-PS1-4: A stable molecule has less energy than the same set of atoms separated; one must provide at least this energy in order to take the
molecule apart.
