Earth, Moon & Solar System — Chapter overview · Earth & Space Science, Grade 9
Model sky patterns, seasons, tides, and predictable orbital motion.
Chapter question
How do motions and geometry explain patterns observed from Earth?
Units in this chapter
- Unit 7.1 · Earth, Moon & Sun: Moon Phases
I can explain that moon phases are caused by our changing view of the Moon's sunlit half, not by Earth's shadow.
- Unit 7.2 · Seasons & Earth's Tilt
I can explain that Earth's tilt, not its distance from the Sun, causes the seasons.
- Unit 7.3 · The Solar System
I can list the eight planets in order from the Sun and classify each as terrestrial, gas giant, or ice giant.
- Unit 7.4 · Gravity, Orbits & Tides
I can describe gravity as an attractive force that depends on mass and distance.
- Unit 7.5 · Predicting Orbits with Mathematical Models
I can use the simplified relation P² = a³ for objects orbiting the Sun.
