Common Standards — cross-referenced to the Common Core State Standards, the Next Generation Science Standards and the California Content Standards.
Standard	Framework	Grade	Subject	Domain
Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.	Next Generation Science Standards	Grade 3	Physical Science	Motion and Stability: Forces and Interactions
Make observations and/or measurements of an object’s motion to provide evidence that a pattern can be used to predict future motion. [Examples: a child swinging in a swing, a ball rolling back and forth in a bowl, and two children on a see-saw.]	Next Generation Science Standards	Grade 3	Physical Science	Motion and Stability: Forces and Interactions
Support an argument that the gravitational force exerted by Earth on objects is directed down.	Next Generation Science Standards	Grade 5	Physical Science	Motion and Stability: Forces and Interactions
Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object & the mass of the object.	Next Generation Science Standards	Middle School	Physical Science	Motion and Stability: Forces and Interactions
Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, & its acceleration. [Objects subject to a net unbalanced force, e.g., an object falling , rolling down a ramp, or a moving- pulled by a constant force.]	Next Generation Science Standards	High School	Physical Science	Motion and Stability: Forces and Interactions

California Standards — cross-referenced to the Common Core State Standards, the Next Generation Science Standards and the California Content Standards.
Standard	Framework	Grade	Subject	Domain
1.a. The position of an object can be described by locating it relative to another object or the background.	CA Science	Grade 2	01. Physical Sciences	1. The motion of objects can be observed and measured.
1.b. An object’s motion can be described by recording the change in its position over time.	CA Science	Grade 2	01. Physical Sciences	1. The motion of objects can be observed and measured.
1.c. The way to change how something is moving is to give it a push or a pull. The size of the change is related to the strength, or the amount of “force,” of the push or pull.	CA Science	Grade 2	01. Physical Sciences	1. The motion of objects can be observed and measured.
1.e. Objects near the Earth fall to the ground unless something holds them up.	CA Science	Grade 2	01. Physical Sciences	1. The motion of objects can be observed and measured.
2.b. When an object is subject to two or more forces at once, the effect is the cumulative effect of all the forces.	Grade 8	01. Physical Sciences	2. Forces	2. Unbalanced forces cause changes in velocity.
2.d. How to identify separately two or more forces acting on a single static object, including gravity, elastic forces due to tension or compression in matter, and friction.	Grade 8	01. Physical Sciences	2. Forces	2. Unbalanced forces cause changes in velocity.
1.b. When forces are balanced no acceleration occurs, and thus an object continues to move at a constant speed or stays at rest (Newton’s First Law).	Grade 9-12	01. Physics	1. Motion and Forces	1. Newton’s laws predict the motion of most objects.
1.d. When one object exerts a force on a second object, the second object always exerts a force of equal magnitude and opposite direction. (Newton’s Third Law).	Grade 9-12	01. Physics	1. Motion and Forces	1. Newton’s laws predict the motion of most objects.
1.g. Circular motion requires application of a constant force directed toward the center of the circle.	Grade 9-12	01. Physics	1. Motion and Forces	1. Newton’s laws predict the motion of most objects.
1.l.* How to solve problems in circular motion, using the formula for centripetal acceleration in the following form: a=v2/r. (achievement is optional)	Grade 9-12	01. Physics	1. Motion and Forces	1. Newton’s laws predict the motion of most objects.
