Lunar Cycle
TAKS Objective 5
The student will demonstrate an understanding of Earth and Space systems.
TEKS 8.12 (A)
analyze and predict the sequence of events in the lunar and rock cycles.
True or False
The phases of the Moon happen when the Earth’s shadow falls on the Moon’s surface.
False
The side of the Moon that is facing the Sun is always lit except during a lunar eclipse.
True or False
The Moon only shines at night.
False
Except close to New Moon, when the Sun is too bright for the Moon to be seen, and Full Moon, the Moon can be seen during certain times of every day.
Objectives
1. The student will be able to analyze and predict the phases of the Moon.
2. The student will be able to determine which part of the Moon can be seen from Earth during each phase.
3. The student will be able to predict the rising and setting of various phases of the Moon.
Lunar Cycle
The moon cycles every 29.5 days
The appearance of the moon is based on the alignment of the sun, Earth, and moon

Waxing and Waning
The terms waxing and waning are used to indicate whether or not the phase of the Moon is getting larger – going from new Moon to full Moon or getting smaller – going from full Moon to new Moon.
A waxing Moon (getting larger) is moving away from the Sun’s position each day and a waning Moon (getting smaller) is moving toward the Sun’s position each day.

Analyzing a Moon Phase Calendar
Explain1. What pattern do you see in the first week
of moon phases?
2. What pattern do you see in the second week of moon phases?
3. What pattern do you see in the third week of moon phases?
4. What pattern do you see in the fourth week of moon phases?
5. What is the difference between the second week and third week?
Explain Continued
6. What pattern do you see concerning the lit side of the moon between the first and fourth week?
7. Does this same pattern hold true in the second and third week?
8. From your study of the patterns found in the phases of the moon predict what phase will be found on the 28th day of the month. Shade in the moon on your calendar.
