Day 1
What are the different phases of the moon? Paste its name on the proper picture.

Our grandparent says that people are more crazy/lunatic during full moon? Is that true? Why is it important to study the phases of the moon?
Background Information
When the moon is between the sun and the Earth, we cannot see the lighted side of moon. This is called New Moon. A day after the new moon, we see a thin slice of light at the edge of the moon. This is called crescent moon. About a week after the new moon, we see half of the lighted side of the moon, this is called first quarter moon. As the first quarter moon increases in size, it is called gibbous moon. About a week after the first quarter moon, the earth is between the moon and the sun. We see the whole lighted side of the moon which is called full moon. The full moon decreases in size until it is again a gibbous moon. About a week after the full moon, we again see half of its lighted part. This is called the last quarter moon. After this, the lighted part becomes smaller until we see a crescent. Soon the moon becomes invisible, after which new moon appears again.
If the moon started its orbit from a spot exactly between Earth and the sun, it would return to almost the same spot in 29 ½ days. If the moon started its orbit around the Earth from a spot in line with a certain star, it will return to that same spot in about 27 ½ days.
Answer the following correctly. Fill in the blanks with the correct answer.
Day 2
How many days does it takes for the moon to complete its phases?
Recite the Poem
30 days has September, April, June and November
All the rest have 31, except February which has 28
And one day more every year in four.
How many days does the cyclic pattern of the moon takes on September?
How many days does the cyclic pattern of the moon takes on January?
What are the months that have the same number of cyclic pattern?
How many days has its pattern have?
How about the other group of months?
What are the 2 ways of moon’s revolution around the earth?
What do you call the months with 27 ½ days moon cyclic pattern?
What do you call the months with 29 ½ days moon cyclic pattern?
Background Information
Scientist measure the time the moon completes one revolution around the Earth in two ways- One is in relation to the sun and the other in relation to a star.
If the moon started its orbit from a spot exactly between Earth and the sun, it would return to almost the same spot in 29 ½ days. During this period, the moon has changed from one new moon phase to the next new moon phase. This period is called a synodic month.
If the moon started its orbit around the Earth from a spot in line with a certain star, it will return to that same spot in about 27 ½ days. This is called a sidereal month.
The term “month” came from the length of time it takes the moon (one month) to complete one revolution around Earth.
Answer the following correctly. Fill in the blanks with the correct answer.
_________ 1. What are the two ways of the scientist to measure the time the moon
completes one revolution around the Earth?
_________2.
_________3. The term that came from the length of time it takes the moon to complete one revolution around the earth.
________4. The month if the moon started its orbit around the Earth from a spot in line with a certain star, it will return to that same spot in about 27 ½ days.
________5. The month with 29 1/2 days cyclic pattern.
Day 3
What are the two ways to measure the time the moon
completes one revolution around the Earth?
What do you call the 27 ½ days moon cyclical pattern?
What do you call the month with 29 ½ days moon cycle?
It is a miniature of the earth
It revolves around the earth.
What do you call the phase of the moon when we cannot see the moon? Why do this happen? After new moon, how many days will it turn to first quarter moon? What do you call the phase of the moon when more than half of it is lighted?
____ ____ ____ ____ ____ _____ ____
Background Information
A full lunar cycle or synodic month lasts almost a month (about 29.5 days), and during that time the moon goes from new to crescent to first quarter to gibbous to full to gibbous to third quarter to crescent and back to new. However, a "full moon," a "new moon," and a "half moon" (first and third quarter) are instants, not periods of time. Because the moon is continuously orbiting the Earth, it will only be absolutely "full" (directly opposite the sun) for an instant before it moves along in its orbit. So the only phases that last any length of time are crescent and gibbous.
The moon is a crescent for about 7.38 days before instantaneously passing first quarter and becoming gibbous. It remains gibbous for another 7.38 days, then becomes full for a split second before becoming gibbous again. After another 7.38-day period, it instantaneously passes third quarter and becomes a crescent. And after another 7.38 days, it completes the cycle by passing the moment of the new moon before becoming crescent again.
The Moon appears to move completely around the celestial sphere once in about 27.3 days as observed from the Earth. This is called a sidereal month, and reflects the corresponding orbital period of 27.3 days The moon takes 29.5 days to return to the same point on the celestial sphere as referenced to the Sun because of the motion of the Earth around the Sun; this is called a synodic month (Lunar phases as observed from the Earth are correlated with the synodic month). There are effects that cause small fluctuations around this value that we will not discuss. Since the Moon must move Eastward among the constellations enough to go completely around the sky (360 degrees) in 27.3 days, it must move Eastward by 13.2 degrees each day (in contrast, remember that the Sun only appears to move Eastward by about 1 degree per day). Thus, with respect to the background constellations the Moon will be about 13.2 degrees further East each day. Since the celestial sphere appears to turn 1 degree about every 4 minutes, the Moon crosses our celestial meridian about 13.2 x 4 = 52.8 minutes later each day.
Arrange the correct cyclical pattern of the moon and write how long each phase o takes to go to another phase.
Day 4
Differentiate synodic month to sidereal month?
2.Ask the pupil if they are familiar with the picture.
Who is she? Where did she get her power?
According to the performance of group what happens to the people of Capiz during the Mid-night of full moon?
Have you experience things like this? Do you think stories like these are true? Why not?
How about the performance of group 2, what did the Filipinos thought of the moon and the stars? Do you believe in the story? Do you know any other stories like this?
Write TRUE or FALSE on the blank.
_________1. People are more crazy/lunatic during full moon.
_________ 2. Moon change its shape.
_________ 3. The moon doesn’t change shape we just see the lighted part of it.
_________ 4. There are two cyclical pattern of the moon.
_________ 5. Werewolves comes out and find food only during full moon.
Background Information
Philippine folklore is a treasure trove of strange mythical creatures that have stood the test of time. Just mention the names aswang, encanto, kapre, tikbalang or tiyanak and you'll get most Filipinos—especially the young ones. Many years ago Filipino people create stories about the origin of moon, its phases, stars and sun that enriched our literature. Those who do not study or research believe these stories but for us who have studied and do our own research do not. It is important to know stories like these because it is part of our culture but it doesn’t necessarily mean we will follow and believe those stories.
Draw Full Moon on the blank before each number if the statement is correct and draw if the statement is not correct.
______1. There is a shadow of a man in the moon because there is a man in the moon
______2. The moon was a silver crescent comb and the stars were necklaces of diamonds.
____3. Moon is made up of big ball of cheese that is why many wants to go to the moon.
____ 4. The moon is a big ball of rocks with craters.
____ 5. Couples should marry during full moon because more blessing will be given to them.
