Phases of the Moon WebQuest Worksheet As you observe the Moon over a month, you notice it changes. Sometimes the right side is in sunlight; other times it s the left. Sometimes you see it at night; sometimes you see it during daytime. This WebQuest will help you understand why the Moon changes shape throughout the month. You will need to read the information available on the webpages you visit. All answers can be found one or more of the websites. Your task is to read and find the information. Task One There are eight major phases of the Moon. In the top of each square, write the phase of the Moon. In the circle, draw a picture of what it looks like. pg. 4
Task Two Define the following terms: Gibbous - Waxing - Waning - Look at the phases of the Moon chart you completed for Task 1. Identify which phases of the Moon are waxing and which phases of the Moon are waning. Phases of the Moon - Waxing Phases of the Moon - Waning Task Three Draw a picture of the Moon phase on the day you were born. My birthdate - pg. 5

Identifying the Phases of the Moon Waxing Crescent A little part of the Moon s right side is lit. Full Moon - The Moon's entire disk is lit because the Earth is between the Sun and the Moon. Gibbous Waxing About ¾ th of the right side Moon's disk is lit. 1 st Quarter - The right half of the Moon's disk is lit. Waxing Getting larger. New Moon - The Moon's disk facing us is dark because the Moon is between the Sun and the Earth. Last Quarter - The left half of the Moon's disk is lit. Waning Crescent - A little part of the Moon s left side is lit. Gibbous Waning - About ¾ th of the left side Moon's disk is lit. Waning Getting smaller. Are the Moons (1-4) waxing or waning? Are the Moons (5-8) waxing or waning? pg. 11
Identify the Phases of the Moon Waxing Crescent when we can see only a sliver of the Moon's disk (right-hand side). Full Moon when the Moon's disk is light because the Earth is between the Sun and the Moon Gibbous Waxing when we can see roughly three-quarters of the Moon's disk (the right side of the Moon is lit). First Quarter can see one-half of the Moon's disk (at First Quarter, you see the right half of the Moon lit [this one-quarter of the entire Moon's surface]). New Moon when the Moon's disk is dark (and invisible to us) because the Moon is between the Sun and the Earth Last/3 rd Quarter can see one-half of the Moon's disk (at Last/3 rd Quarter, you see the left half of the Moon lit [this one-quarter of the entire Moon's surface]). Gibbous Waning when we can see roughly three-quarters of the Moon's disk (the left side of the Moon is lit). Waning Crescent when we can see only a sliver of the Moon's disk (left-hand side). Using the table above, write the phase of the Moon shown in the picture pg. 12

Moon is almost directly between Sun and Earth. b. Full Moon (cycle starts again) 3. A bit of the Sunlit side of the Moon shows, with c. New Moon The Sunlit side being on the right. 4. Two weeks have passed since the New Moon. d. Waxing Crescent Moon 5. The Moon is three quarters of its way around Earth. e. First Quarter Moon 6. The Moon is a quarter of its way around Earth. f. Waning Crescent Moon 7. A bit of the Sunlit side of the Moon shows with the g. Last Quarter Moon lighted side being on the left. 8. The Moon is between Full Moon and Last Quarter. h. Waxing Gibbous Moon 9. The Moon is increasing in light between a First i. Waning Gibbous Moon First Quarter Moon and a Full Moon. 10. The Moon is decreasing in light between a Full Moon j. New Moon And a Last Quarter Moon. pg. 13
Drawing Moon Phases Using the description and matching words, complete worksheet by adding the drawing of that phase of the Moon. Description 1. New Moon Moon is almost directly between the Sun and Earth (start of cycle). Drawing. 2. Waxing Crescent Moon A bit of the Sunlit side of the Moon shows on the right side. 3. First Quarter Moon The Moon is a quarter of its way around the Earth. It is in its First Quarter phase. 4. Waxing Gibbous Moon The Moon is increasing in light between a First Quarter Moon and a Full Moon. 5. Full Moon Two weeks have passed since the New Moon. We see the entire face of the Moon shining. 6. Waning Gibbous Moon The Moon is decreasing light between a Full Moon and a Last Quarter Moon. pg. 14
7. Last Quarter Moon The Moon is three-quarters of its way around Earth. It is in its Last Quarter phase. 8. Waning Crescent Moon A bit of the waning Sunlit side of the Moon shows on the left side. 9. New Moon Moon is almost directly between the Sun and Earth (cycle starts again). pg. 15

Comparing Waxing and Waning Moons What is the difference between a waning Moon and a waxing Moon? Your assignment is to make a backward-book explaining the difference. You will include the following information: Define the term (waxing or waning). Identify which Moon phases are waxing or waning. An example of a forward-backward book is available for you. Instructions for making a forward-backward book. 1. Stack three or more sheets of paper. On the top sheet, trace a large circle. 2. With the papers still stacked, cut out the circles. 3. Staple the paper circles together along the left-hand side to create a book. 4. Label the cover and takes notes on the pages that open to the right. 5. Turn the book upside down and label the back. Takes notes on the pages that open to the right. pg. 17

Phases of the Moon Lab General Procedure: Answer each of the following questions in complete sentences after discussion within your group. You may compare your work with an adjacent group as necessary to arrive at a group consensus. Each group member has a Moon lollipop. The lamp represents the Sun. Each person will hold their lollipop towards the Sun. You represent the Earth. The Moon revolves around you. The diagram will help you label the different phases of the Moon. Waxing vs. Waning Directions and Questions 1. The Moon should be between the Sun and the Earth. Note how the side opposite the Earth is the side that is lit. This phase is called New Moon.

Your Moon should move until it is 3/8 of a revolution around the Earth. Which side of the Moon is lit - right or left (circle one)? Draw a picture of the Moon, Earth, and Sun. Phase - pg. 22
5. Your Moon should move until it is ½ of a revolution around the Earth. How much of the Moon is lit -? Draw a picture of the Moon, Earth, and Sun. Phase - 6. Your Moon should move until it is 5/8 of a revolution around the Earth. Which side of the Moon is lit - right or left (circle one)? Draw a picture of the Moon, Earth, and Sun. Phase - 7. Your Moon should move until it is ¾ of a revolution around the Earth. Which side of the Moon is lit - right or left (circle one)? Draw a picture of the Moon, Earth, and Sun. Phase - 8.
