Why do objects in our solar system orbit the sun?
Why do objects in our solar system orbit the sun?
Level 4: In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications that go beyond what was taught.
Level 3: Student can use mathematical or computational representations (Kepler's and Newton's Laws) to predict and explain the motion of orbiting objects in the solar system.
Level 2:
A1. Use focal distance and an ellipses' major axis length to determine eccentricity of an object's orbit in space (Kepler's 1st Law)
A2. Describe how distance from the sun impacts the velocity of an object's orbit in space (Kepler's 2nd Law)
A3. Describe how distance from a star is proportional to the orbital period (Kepler's 3rd Law)
A4. Describe the relationship of scale, proportion and quantity in the context of gravitational attraction (Newton's Laws)
Level 1: Studentโs performance reflects insufficient progress towards foundational skills and knowledge.
