Dear Mr. Spahr:
Thank you for allowing us to consider using one or more of your students’ calendars for
our upcoming calendar production. As we already discussed, we are interested in Space-
themed calendars with an educational twist. The following lays out what we are looking
for specifically. Please let me know if I can be of further assistance.
Within each day of the month:
A representation of the phase of the moon for that day – every day.
Every New Moon labeled
Every 1st Quarter Moon labeled
Every Full Moon Labeled
Every 3rd (Last) Quarter Labeled
Winter Solstice labeled
Spring Equinox labeled
Summer Solstice labeled
Fall Equinox labeled
Your birthday (as the creator, you should get some credit)
Above each month’s calendar: scientific diagrams, tables, graphs, pictures, word art about the
cyclical movements of the Sun, Earth, and Moon, as indicated for each month:
January: Illustrate how the tilted earth rotates on its axis causing day and night.
Include a brief statement explaining the illustration.
February: Create a data table showing the sunrise, sunset, and length of day on
the first day of each month for a year in Edmonton, Houston, Mogadishu,
Tromsö, Antarctica, and Sydney. Create a line graph of the length of day for
each date for each location. Explain why we have Leap Year.
March: Illustrate the positions of the Sun, Earth, and Moon for the Spring Tide.
Include a brief statement explaining the illustration/spring tides. Also include a
brief statement explaining the Spring Equinox.
April: Write a paragraph comparing and contrasting the seasons in the Northern
and Southern Hemisphere. Be sure to explain why there are
similarities/differences. Include an illustration.

in Celsius for the month of August in the following major cities: Edmonton,

September: An illustration that represents the positions of the sun, earth, and
moon for the Neap Tide. Write a brief explanation of the Autumnal (Fall)
Equinox.

earth, and moon. Illustrate the relative sized and positions of the earth, sun, and
moon.
November: Illustrate how the tilted earth rotates on its axis and revolves around
the sun causing changes in the seasons. Show the position of the sun and earth
for winter, spring, summer, and fall in the SOUTHERN hemisphere.

constant position in the night sky. Also provide an illustration of the earth tilted
