- (a) Physical Science. Motion and Stability: Forces and Interactions.
- (1) Performance expectation 1. Plan and conduct investigations on the effects of balanced and unbalanced forces on the motion of an object.
- (A) Clarification Statement. Examples could include that an unbalanced force on one side of a ball can make it start moving and balanced forces pushing on a box from opposite sides will not produce any motion at all.
- (B) Assessment Boundary. Assessment is limited to one variable at a time: number, size, or direction of forces. Assessment does not include quantitative force size, only qualitative and relative. Assessment is limited to gravity being addressed as a force that pulls objects down.
- (C) Science and Engineering Practices. Planning and Carrying Out Investigations. Plan and conduct an investigation collaboratively to produce data to serve as the basis for evidence, using fair tests in which variables are controlled and the number of trials considered.
- (D) Disciplinary Core Ideas.
- (i) Forces and Motion.
- (I) Each force acts on one particular object and has both strength and a direction.(II) An object at rest typically has multiple forces acting on it, but they add to give zero net force on the object.
- (III) Forces that do not sum to zero can cause changes in the object’s speed or direction of motion.
- (ii) Types of Interactions. Objects in contact exert forces on each other.
- (E) Crosscutting Concepts. Cause and Effect. Cause and effect relationships are routinely identified.
- (F) Connections to Scientific Literacy. Scientific Investigations Use a Variety of Methods. Science investigations use a variety of methods, tools, and techniques.
- (2) Performance expectation 2. Make observations and/or measurements of an object’s motion to provide evidence that a pattern can be used to predict future motion.

- (B) Assessment Boundary. Assessment does not include technical terms such as magnitude, velocity, momentum, vector quantity, period, and frequency. Assessment can include the concept that some quantities need both size and direction to be described.
- (C) Science and Engineering Practices. Planning and Carrying Out Investigations. Make observations and/or measurements to produce data to serve as a basis for evidence for an explanation of a phenomenon.
- (D) Disciplinary Core Ideas. Forces and Motion. The patterns of an object’s motion in various situations can be observed and measured; when that past motion exhibits a regular pattern, future motion can be predicted from it.

Examples of magnetic force could include the force between two permanent magnets, the force between an electromagnet and steel paper clips, and the force exerted by one magnet versus the force exerted by two magnets. Examples of cause and effect relationships could include how the distance between objects affects strength of the force and how the orientation of magnets affects the direction of the magnetic force.

- (C) Science and Engineering Practices. Asking Questions. Ask questions that can be investigated based on patterns such as cause and effect relationships.
- (D) Disciplinary Core Ideas. Types of Interactions. Electric and magnetic forces between a pair of objects do not require that the objects be in contact. The sizes of the forces in each situation depends on the properties of the objects and their distances apart, and, for forces between two magnets, on their orientation to each other.
