What children learn in Level 6

  • The moon's phases have names. Here are the main shapes: new, crescent, quarter, gibbous, and full.
  • After the new moon, the lit part grows each night, lit on the right side. Growing is called waxing: waxing crescent, first quarter, waxing gibbous, then full.
  • After the full moon, the lit part shrinks, now lit on the left side. Shrinking is called waning: waning gibbous, third quarter, waning crescent, and back to new.
  • A quarter moon looks like half a circle. It's called a quarter because the moon is a quarter of the way around its trip.

Georgia Standards of Excellence in Science:

  • S4E2.b β€” Develop a model based on observations to describe the repeating pattern of the phases of the moon (new, crescent, quarter, gibbous, and full).
