Moon phases, or the lunar cycle, happen because the moon is constantly orbiting our planet. From earth, we see the new moon as a tiny sliver of light in the sky, gradually getting bigger until we see the full moon, then waning again. This is because the side of the moon facing the sun is illuminated. Making a lunar calendar can be an interesting project and help you keep track of what's happening in the night sky.
Download a free calendar template from the Internet. Choose a monthly template that uses large squares for each day because you will need the space to add your lunar cycle later on.
Use a high quality paper, colored or plain, and print out your calendar templates for each month of the year.
Source a picture or pictures of the moon, either from the Internet or by scanning your own moon photos into the computer.
Place the monthly templates back into the printer, upside down this time so that the picture will be on the opposite side of the page to the calendar. When the calendar is hanging up, you will see the current month and a picture of the moon above it, on the back of the previous month.
Place all 12 pages on top of each other, calendar side facing up and use a hole-punch to add two holes to the top of the pages. Add a piece of card to the back of the calendar pages for extra support and to make the pages easier to turn.
Snip off two lengths of jewelry wire about two inches long. Post one piece of wire through each hole in the pages and secure by twisting the ends together, allowing you to flip easily through the calendar. Finally punch one hole in the center at the bottom of the pages, to allow the calendar to be hung by string or a drawing pin.
Print out the phases of the moon, using the link in the References section. Choose either the main phases--new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter and waning crescent--or the entire lunar cycle.
Cut out the pictures of each moon shape to use as templates. Using the Moon Calendar in the Resources section, place each moon shape in the center of the square on the appropriate day on the calendar.
Draw around each moon shape with a silver pen. Using a silver pen prevents the moon shape from interfering with any events you may wish to write onto the calendar.
Write the name of the main moon phases on the appropriate day in silver pen.
Decorate your lunar calendar with moon and star stickers and glitter.
