Phases of the Moon

In Science, we have really been enjoying ourselves learning about the phases of the Moon. During the month of October, students will also be observing the Moon each night outside their window and recording it's changing appearance, allowing them to see and experience our Moon's 29 day cycle.

We have learned that the Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes about 27 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) lasts about 29 days. The Moon spends the extra 2 days "catching up" because Earth travels about 45 million miles around the Sun during the time the Moon completes one orbit around Earth.

As we study the Moon's phases,we will also make booklets to help us learn what each phase is called. In doing this, we will identify several phases as being landmark phases. These are:

1) New Moon (the first (1)and last (29) day of the cycle)
At the New Moon phase, the Moon is so close to the Sun in the sky that none of the side facing Earth is illuminated. In other words, the Moon is between Earth and Sun.

2) First Quarter Moon (Day 8)
ONE QUARTER (the RIGHT quarter that we see) is lit....here, the moon is highest in the sky at sunset, then sets about six hours later.

3) Full Moon (Day 15- the middle day in the 29 day cycle)
On this day, the Moon is behind Earth in space with respect to the Sun. As the Sun sets, the Moon rises with the side that faces Earth fully exposed to sunlight. We are able to see the entire illuminated half of the moon! (Did you know that only one half of our Moon is always illuminated by our Sun, and that we NEVER see the other half from Earth??!!).

4) Last Quarter Moon (Day 21) ONE QUARTER (the LEFT quarter that we see) is lit.... (opposite of the First Quarter Moon).

Other terms students are gaining familiarity with to explain other phases that fall between these landmark phases are Waxing, Waning, Crescent and Gibbous.
We have learned that "waxing" means "increasing" (growing) illumination and "waning" means "decreasing" (shrinking) illumination.
We also know that "gibbous" means "hump-backed" and "crescent" means "a shape resembling a segment of a ring". Understanding the meanings of these words is very important in helping us to recognize the different phases of the moon correctly.
Be sure to visit Chapter 2, Lesson 2 in your science textbook online if you need to review this information about the moon. You can also log on to GIZMOS at any time to review the virtual lab we have been working on in class!!

Mr. Lee's Moon Rap video has also been a wonderful reference for us in class- check it out HERE.

Students, look out your window tonight. What phase of the moon do you see (and how do you know)? Leave a comment to let us know.
