Welcome to the DC Digital Lab!

Tuesday Feb 1 will be Lunar New Year or Chinese New Year. Many places on earth mark January 1st as the start of the new year because they base the calendar on the Earth’s movement around the sun.  The Chinese calendar is based on the lunar calendar, which tracks the year using lunar cycles. This Digital Lab is all about phases of the moon.

 

Moon Phases

Have you ever looked at the moon at night? Did you notice that it looks different? This is because the moon cycles through 8 different phases within the span of a month. Phase one is a new moon, this is when the side of the moon that faces the Earth is not hit by sunlight. The moon is not typically visible during the new moon. Phase 2 consists of the waxing crescent, less than half of the moon is lit up and the size slowly increases. Phase 3 is known as the first quarter, in which half the moon is lit by the sun. Phase 4 is the waxing gibbous; half of the moon is lit and gradually gets bigger. A full moon is Phase 5, when the side facing the Earth is lit up by the sun entirely. Phase 6 is the waning gibbous, and the lit part is getting smaller. Phase 7 is the last quarter in which half the moon is lit by the sun, and Phase 8 is the waning crescent, which is a small sliver of moon present.

Fun and tasty activity…

We love snacks here at the Discovery Center. Grab a black and white chocolate sandwich cookie (you know the ones. we like ours dounle stuffed!) Can you take one side of the cookie and make it look like the phases of the moon? Go ahead. Try with multiple cookies. It’s delicious and educational!
