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?
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.
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.
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.
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.
The moon completes one revolution around earth in about 28 days or almost a month.

Name the phases of the moon
Describe the moon.
Why the moon changes its appearance?
Presenting examples/ instances of the lesson
Can You Guess?
Materials: Worksheet, marker, group of pupils
What to do:
1. Group the pupils into four.
2. Recall standards.
3. Give activity sheets to read
4. Ask the group of pupils to brainstorm and make inferences on the patterns in the changes in the appearance of the moon.
4. Allot 5 minutes for this activity.
Group 1
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.
Guide questions
1.Why does the moon called as satellite of the earth?
2.In terms of densities, how was moon compared to Jupiter?
3.Within the satellite in the solar system, what was moon compared to others?
4. Why was it called a natural satellite?
Group 2
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.
Guide questions:
1.How long does moon to have exist?
2.How was moon formed?
3.How will you describe the moon?
4. What was the effect of its gravitational force?
Group 3
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.
Guide questions:
1. How was the moon move in relation to the earth?
2. What was the two side of the moon called?
3. What does celestial object means?
Group 4
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.

Finding practical applications of concepts and skills in daily living
If you want to check on how a crescent moon looks like, what object at home will you use to best represent the sun, moon, earth?
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.
____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.
Additional activities for application or remediation
Interview an old member in the family about a myth that he/she knew about the moon. Share it in class.
