8th Grade Science Unit 1: Motion, Forces & Energy / 13-14 /
Reporting Cluster: Forces and Interactions
Topic / Knowledge: / Assessments:
Motion / 4 / In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications that go beyond what was taught.
3
Proficient / Students demonstrate they have developed an understanding of:
  • The motion of an object can be described by its position, direction of motion and speed. That motion can be measured and represented on a graph.
  • acceleration can be a change in speed, direction or both
Students demonstrate they have the ability to:
  • manipulate the formula s = d/t to determine an object’s speed, distance or time
  • graph an object’s motion

2 / Students will recognize or recall:
Specific vocabulary such as:
  • speed, acceleration, velocity, reference point, distance, constant, time
Basic knowledge such as:
  • velocity is speed with a direction
  • acceleration is a change in velocity
  • speed is calculated as distance/time
  • motion is a change in position
  • a graph can represent an object’s change in position

Forces / 4 / In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications that go beyond what was taught.
3
Proficient / Students demonstrate they have developed an understanding of:
  • An object that is not being subjected to a force will continue to move at a constant speed and in a straight line (Newton’s 1st Law).
  • If more than one force acts on an object along a straight line, then the forces will reinforce or cancel one another, depending on their direction and magnitude. Unbalanced forces will cause changes in speed or direction of an object’s motion (Newton’s 1st Law).
  • The relationship between an object’s mass, acceleration and the force applied (Newton’s 2nd Law).
  • Objects in contact exert forces on one another (friction, elastic, pushes & pulls)
  • Newton’s 3rd Law and its application to practical situations.

2 / Students will recognize or recall:
Specific vocabulary such as:
  • force, net force, friction, gravity, momentum, mass, weight, balanced, unbalanced, inertia, Newtons
Basic knowledge such as:
  • Newton’s 3 Laws
  • how balanced and unbalanced forces affect motion
  • gravity is affected by mass and distance
  • how friction affects motion
  • weight is a function of gravity

Reporting Cluster: Energy and Energy Transfer
Topic / Knowledge: / Assessments:
Energy and Energy Transfer / 4 / In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications that go beyond what was taught.
3
Proficient / Students demonstrate they have developed an understanding of:
  • the conversion of energy from one form to another
  • the Law of Conservation of Energy, including conversions and friction
  • Heat moves in predictable ways, flowing from warmer objects to cooler ones, until both reach the same temperature.
  • all forms of energy can be classified as potential and/or kinetic energy
  • various energy transfer mechanisms and can give examples

2 / Students will recognize or recall:
specific vocabulary such as:
  • potential, kinetic, mechanical, chemical, light, sound, electrical, thermal, nuclear, conservation, heat, temperature, conversion, Joules, convection, conduction, radiation, transfer, efficiency
basic knowledge such as:
  • the Law of Conservation of Energy
  • the difference between heat and temperature
  • the difference between potential and kinetic energies
  • chemical, light, sound, electrical, thermal, nuclear and mechanical are all forms of energy
  • energy can transfer through radiation, conduction or convection
