MS-PS2-3. Ask
questions about data to determine the factors that affect the strength of
electric and magnetic forces.
[Clarification Statement: Examples of
devices that use electric and magnetic forces could include
electromagnets, electric motors, or generators. Examples of data could
include the effect of the number of turns of wire on the strength of an
electromagnet, or the effect of increasing the number or strength of
magnets on the speed of an electric motor.] [Assessment Boundary:
Assessment about questions that require quantitative answers is limited to
proportional reasoning and algebraic thinking.]
Planning and Carrying Out Investigations
● Collect data to produce data to serve as the basis for evidence to answer scientific questions
Students could collect data to serve as the basis for evidence to answer scientific questions [about what effects] the size of electric and magnetic forces. MS-PS2-3
Analyzing and Interpreting Data
● Analyze data to define an optimal operational range for a proposed object, tool, process or system that best meets criteria for success.
Students could analyze data to define an optimal operational range for a proposed tool [that incorporates] electric forces, [whose] sizes depend on the magnitudes of the charges and currents involved and on the distances between the interacting objects. MS-PS2-3
Using
Mathematics and Computational Thinking
● Use digital tools and/or mathematical concepts and arguments to test and compare proposed solutions to an engineering design problem.
Students could use digital tools to test and compare proposed solutions [that incorporate] magnetic forces, [which] can be attractive or repulsive. MS-PS2- |

MS-PS2-4.
Construct and present arguments using evidence to support the claim that
gravitational interactions are attractive and depend on the masses of
interacting objects.
[Clarification Statement: Examples of evidence for arguments could
include data generated from simulations or digital tools; and charts
displaying mass, strength of interaction, distance from the Sun, and
orbital periods of objects within the solar system.] [Assessment Boundary:
Assessment does not include Newton's Law of Gravitation or Kepler’s
Laws.]
Obtaining, Evaluating, and Communicating Information
● Integrate qualitative and/or quantitative scientific and/or technical information in written text with that contained in media and visual displays to clarify claims or findings.
Students could integrate qualitative and/or quantitative scientific information in written text [about the] gravitational force between any two masses, [which] is very small except when one or both of the objects have large mass, with that contained in media and visual displays to clarify claims or findings.

MS-PS2-5.Conduct
an investigation and evaluate the experimental design to provide evidence
that fields exist between objects exerting forces on each other even
though the objects are not in contact.
[Clarification Statement: Examples of this
phenomenon could include the interactions of magnets, electrically-charged
strips of tape, and electrically-charged pith balls. Examples of
investigations could include first-hand experiences or simulations.]
[Assessment Boundary: Assessment is limited to electric and magnetic
fields, and limited to qualitative evidence for the existence of fields.]
Developing and Using Models
● Develop or modify a model— based on evidence – to match what happens if a variable or component of a system is changed.
Students could modify a model [of] fields that extend through space and their effect on an object, based on evidence, to match what happens if a variable or component of a system is changed. MS-PS2-5
Systems and System Models
● Models can be used to represent systems and their interactions—such as inputs, processes and outputs—and energy, matter, and information flows within systems.
Students could use a model to represent systems [of] forces that act at a distance (electric and magnetic) and their interactions and energy flows [by] mapping their effect on an object (e.g., a charged object, or a ball). MS-PS2-5 |

MS-PS3-2. Develop a
model to describe that when the arrangement of objects interacting at a
distance changes, different amounts of potential energy are stored in the
system. [Clarification Statement:
Emphasis is on relative amounts of potential energy, not on calculations
of potential energy. Examples of objects within systems interacting at
varying distances could include: the Earth and either a roller coaster
cart at varying positions on a hill or objects at varying heights on
shelves, changing the direction/orientation of a magnet, and a balloon
with static electrical charge being brought closer to a classmate’s hair.
Examples of models could include representations, diagrams, pictures, and
written descriptions of systems.] [Assessment Boundary: Assessment is
limited to two objects and electric, magnetic, and gravitational
interactions.]
Engaging
in Argument from Evidence
● Evaluate competing design solutions based on jointly developed and agreed-upon design criteria.
Students could evaluate competing design solutions [that use] stored (potential) energy – [which] depends on the relative positions [of objects]. MS-PS3-2
Cause & Effect
●Cause and effect relationships may be used to predict phenomena in natural or designed systems.
Students could use cause and effect relationships to predict phenomena in natural or designed systems [related to the concept that] a system of objects may contain stored (potential) energy, depending on their relative positions.MS-PS3-2 |
