SCIENCE.8.7.A — Vertical Alignment

Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.

Previous grade

S.1.7.A

explain how pushes and pulls can start, stop, or change the speed or direction of an object's motion; and

S.1.7.B

plan and conduct a descriptive investigation that predicts how pushes and pulls can start, stop, or change the speed or direction of an object's motion.

S.2.7.B

plan and conduct a descriptive investigation to demonstrate how the strength of a push and pull changes an object's motion.

S.3.7.B

plan and conduct a descriptive investigation to demonstrate and explain how position and motion can be changed by pushing and pulling objects such as swings, balls, and wagons.

S.5.7.A

investigate and explain how equal and unequal forces acting on an object cause patterns of motion and transfer of energy; and

S.6.7.B

calculate the net force on an object in a horizontal or vertical direction using diagrams and determine if the forces are balanced or unbalanced; and

S.6.7.C

identify simultaneous force pairs that are equal in magnitude and opposite in direction that result from the interactions between objects using Newton's Third Law of Motion.

S.7.7.D

analyze the effect of balanced and unbalanced forces on the state of motion of an object using Newton's First Law of Motion.

S.8.7.A

calculate and analyze how the acceleration of an object is dependent upon the net force acting on the object and the mass of the object using Newton's Second Law of Motion; and

S.8.7.B

investigate and describe how Newton's three laws of motion act simultaneously within systems such as in vehicle restraints, sports activities, amusement park rides, Earth's tectonic activities, and rocket launches.

PHYS.5.E

explain and apply the concepts of equilibrium and inertia as represented by Newton's first law of motion using relevant real-world examples such as rockets, satellites, and automobile safety devices;

PHYS.5.G

illustrate and analyze the simultaneous forces between two objects as represented in Newton's third law of motion using free body diagrams and in an experimental design scenario; and
