Exploring Moon Phases

4th Grade35 minutesNGSS 4-ESS1-1

Learning Objective

I can describe the patterns of the Moon’s phases.

Key Concepts

The moon appears to change shape a little bit every night, which are called phases, because we see different amounts of the moon lit up by the sun.

The cycle of lunar phases begins with the new moon, when the moon appears completely dark, and ends with the full moon, when the moon is the biggest and brightest.

The phases of the moon in order are: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent.
