Investigation

**This was an adult build for us**

  1. Using your yellow sharpie, draw and fill in a small circle to represent your moon on the outside of one of the clear cups.Moon Phase Cups (45)
  2. Place your “moon cup” inside the second cup. Slowly rotate around the outside cup drawing the next moon phase (8 total) over your moon in black sharpie. Label the different phases of the moon. New Moon –> Waxing Crescent –> First Quarter –>Waxing Gibbous –>Full –> Waning Gibbous –> Third Quarter –> Waning Crescent –> New Moon.Moon Phase Cups (37)Moon Phase Cups (38)Moon Phase Cups (39)Moon Phase Cups (40)Moon Phase Cups (41)Moon Phase Cups (42)Moon Phase Cups (43)Moon Phase Cups (44)
  3. Have your little scientist slowly spin the outside cup around to view the 8 phases of the moon and talk about how the moon looks different during different times of the month.Moon Phase Cups (21)

Talking Points

 The Lunar phase or Moon phase is how the moon looks from Earth based on the sunlight shining on it. When we have a Full Moon the Earth is blocking none of the sunlight from hitting the moon so it is fully visible from Earth. When we have a New Moon the Earth is in-between the sun and moon,  the sun’s light is completely blocked from illuminating the moon, so we do not see the moon during a new moon. As the Earth and moon travel around the sun the view of the moon changes slightly as the month progresses going through eight different phases over the course of the month. The moon phases progress from New Moon –> Waxing Crescent –> First Quarter –>Waxing Gibbous –>Full –> Waning Gibbous –> Third Quarter –> Waning Crescent –> New Moon.

Extended Learning: Have even more fun studying the moon.
