presentation

1. Based from : Science Exemplar 5 by Science Writing Team Batangas Province PPT created by: PRECILA R. UMALI-JZMES Week 6 Day 1 Describe the phases of the moon Day 5- is summative test

2. Review What is the most noticeable thing you probably see at night when you look up the sky?

3. Developing mastery Look at the illustration of the phases of the moon and write its name. New moon full moon half moon gibbous moon Cresent moon 1._____________ 2 ._____________ 3 ._____________ 4 ._____________ 5 ._____________

4. Finding practical applications of concepts and skills in daily living During the olden days, the phases of the moon were used as basis of people in doing their daily activities like full moon offers big catch to fishermen. Do you think fishermen now a days are still following that belief?

5. Making generalizations and abstractions about the lesson. Moon is the nearest earth’s neighbor in space. As it orbits the earth, the Moon seems to change shape and disappear. It is due to the part that is light by the sun as it goes around . The lighted part of the moon is called the moon’s phase.

6. Phases of the Moon 1. New Moon – the unlighted side of the moon faces the earth that makes it invisible when viewed from the earth. The moon and the sun are aligned on the same side of the earth. 2. Crescent Moon – after one or two days, small edge of the moon is lighted.

7. First Quarter Moon – after a week, half of the moon is lighted. Gibbous Moon - After a few days, we see more than half of the moon lighted. Full Moon - After one week, the whole side of the moon facing the earth becomes lighted. This happens when the earth is between the sun and the moon.

8. From the full moon until a new moon, the amount of lighted surface visible from the earth decreases. This period when the moon appears to be decreasing in size is called a waning moon . That’s why as the moon continues the second half of its orbit, you see another gibbous, quarter, crescent phases before the new moon.

9. The moon completes one revolution around earth in about 28 days or almost a month. Evaluating Learning Use a yellow crayon to color the circle to show the phases of the moon 1 . full moon 2 . new moon

10. 4. Fourth quarter 3. First quarter 5 . Gibbous moon

11. The Moon is an astronomical body that orbits planet Earth, being Earth's only permanent natural satellite. It is the fifth-largest natural satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits (its primary). Following Jupiter's satellite Io, the Moon is the second-densest satellite among those whose densities are known.

12. The Moon is thought to have formed about 4.51 billion years ago,  not long after Earth . The most widely accepted explanation is that the Moon formed from the debris left over after a  giant impact  between Earth and a  Mars -sized body called  Theia ..its surface is actually dark, although compared to the night sky it appears very bright, Its gravitational influence produces the  ocean tides ,  body tides , and the  slight lengthening  of the day.

13. The Moon is in  synchronous rotation  with Earth, always showing the same face, with its  near side  marked by dark volcanic  maria  that fill the spaces between the bright ancient crustal highlands and the prominent  impact craters . As seen from the Earth, it is the second-brightest regularlyvisible   celestial object  in Earth's sky, after the Sun.

14. The   Soviet Union 's  Luna program  was the first to reach the Moon with  unmanned spacecraft  in 1959; the United States'  NASA   Apollo program  achieved the only manned missions to date, beginning with the first manned lunar orbiting mission by  Apollo 8  in 1968, and six manned lunar landings between 1969 and 1972, with the first being  Apollo 11 . These missions returned  lunar rocks  which have been used to develop a  geological  understanding of the Moon's origin,  internal structure , and  later history . Since the  Apollo 17  mission in 1972, the Moon has been visited only by unmanned spacecraft .

15. Making generalizations and abstractions about the lesson The patterns in the changes in the appearance of the moon is due to the relative position of the sun, earth and the moon. Evaluating Learning Write T if the inference is possibly correct, and F if it is not . _______1. It is full moon when the moon is between the sun and the earth.

16. ____2 . New moon occurs when the earth is between sun and moon. ____3 . Gibbous moon occurs when we see more than half of the moon is lighted. ____4 . After the gibbous moon, half of the moon’s face is seen. ____5 . After the crescent moon, half of the moon is lighted.

17. Review Draw and write the phases of the moo n following the illustration .

18. Evaluating Learning Write T if the statement explains the reasons why the moon undergo changes in appearance and F if it does not. ____1. It is full moon when the moon is between the sun and the earth. ____2. New moon occurs when the earth is between sun and moon. ____3. Gibbous moon occurs when we see more than half of the moon lighted

19. __4. After the gibbous moon, half of the moon’s face is seen. We see last quarter. ___5. After the crescent moon, half of the moon is lighted. We see the first quarter. Additional activities for application or remediation Do the activity below. This serves as your two-week activity.
