OCTOBER MOONWATCH GRAPH

OBJECTIVE: FIND PATTERNS IN THE TIMES OF MOONRISE/MOONSET FOR
THE MONTH OF OCTOBER

TIME NEEDED : Two or three periods

MATERIALS:
Calendar of moonrise/moonset times
Pencil
Graph paper

PROCEDURE:

1. Hand out the calendar of monthly sunrise/sunset, moonrise/moonset times from www.sunrisesunset.com
2. Have students make a table with the following headings.
MOONRISE MOONSET

DATE 12 HR CLOCK 24HR CLOCK 12 HR CLOCK 24 HR CLOCK

3. The times given in the calendar are in daylight savings time. Have students convert these times to Standard Time.
4. The times given in the calendar are according to a 12 hr. clock. Have students convert the times to a 24 hr. clock.
5. Have students join two pieces of graph paper together.
6. Label the y axis from 0 to 23 : HOURS OF THE DAY
7. Label the x axis from 1 to 31: DAYS OF THE MONTH
8. Make a bar graph for each day.
9. Make a horizontal line at the time of moonrise for each day. Label the line “R: and write the time.
10. Make a horizontal line at the time of moonset for each day. Label the line “S” and write the time.
11. Darken the bar between the times of moonset and moonrise.
12. On a separate piece of paper, write about the patterns you see in this graph.
13. Draw the new moon, first quarter moon, full moon, and thirdquarter moon at the time they are directly overhead
(at zenith).
14. Draw a waxing crescent and waxing gibbous moon at the time it is overhead.
15. Draw a waning crescent and waning gibbous moon at the time it is overhead.

MOON PATTERNS

OBJECTIVE: ANALYZE , DESCRIBE, AND PREDICT PATTERNS IN THE CHANGING PHASES OF THE MOON.

Time Needed: One or two periods

Materials: Pictures of the changing phases of the moon for thirty consecutive days.

Procedure:

1. Hand out the pictures of the changing phases of the moon.
2. Elicit previous knowledge that students might have about the moon: Write the facts on the board.
3. Ask students to find the pattern in the changing areas of light and dark on the moon.
4. Ask students to describe the pattern. Write their descriptions on the chalkboard using their own words.
5. Introduce the vocabulary: new moon, first quarter, third quarter, full moon, crescent, gibbous, waxing, waning.
6. Ask students to write the description of the changing shapes of the moon in their journals using the new vocabulary.
Write the dates of the four main phases of the moon on the board:
a. Third Quarter: September 4
b. New: September 11
c. First Quarter: September 19
d. Full Moon (Harvest Moon): September 26
7. Have students label each of the main phases with the date of that phase.
8. Ask students to fill in the dates of the waning and waxing crescent and gibbous phases in between.
9. Ask students to predict the date of the third quarter after the Harvest Moon.
10. Ask students to write a rhyme or mnemonic device that will help them remember that the waxing moon is seen on the right and the waning moon is seen on the left.


Questions:

1. State the difference between
a. waxing and waning
b. crescent moon and gibbous moon
c. full moon and new moon
d. 1st quarter and 3rd quarter
2. Show the difference in drawings.

3. How can we tell if a crescent moon is waxing or waning?
