Free Moon Observation Journal for Kids~


Kids are always naturally curious about the night sky, especially the moon! Lucy and Theo are always wondering why there are nights we can’t see the moon at all and are especially curious about why it always seems to change.


I decided to create this simple moon journal so we could observe the moon each night and notice the changes that occur as the days go by. (This post contains affiliate links.)

How to Use the Moon Journal

1. Print out one copy of the moon journal for each person.

2. Write the starting date at the top of your journal. (You can even use a fun pencil like this one!) Aim to check the moon around the same time each night. Notate the time at the top.


3. Each night observe the moon. Write the date below the small box you will be using and shade in the circle to resemble how the moon looks. Each night the moon will look different and be located in a different part of the sky!

4. Continue recording your observations each night.  (On nights we weren’t able to check the moon, we put an ‘x’ over the box, and on nights it was too cloudy, we drew clouds over our moon.)

5. Once your journal is complete, look for patterns. What do notice?


More Information about the Moon

  • It takes 29 1/2 days for the moon to go from a new moon back to a new moon.
  • Waxing is when the lighted part of the moon gets bigger each night. Waning is when the lighted portion starts getting smaller.
  • The moon rises at a different time each day of the month.
  • This website has a nice chart with the phases of the moon and a map of the moon.
  • You can check your local newspaper to see when the moon is new. There’s also websites like this one.

  1. Thanks for the activity and for the printable! Your site is great!

  2. So excited about this activity and your moon books post. Peanut is suddenly quite interested in astronomy. You’ve given us some fun ways to start exploring this interest!

  3. Thank you for sharing your wonderful printable. Love the observations and wish we had this when we were studying the phases of the moon.

  4. I would love to print out the journal. Is there a way to do that without google drive access?

  5. Thank you so much for the moon journal idea and graphic. I was wondering since moon rise and moon fall change so much over the 28 days how you were able to see the moon each day/night when you were making your observations at the same time? Or how you were even able to see the moon each day if you did look at different times each day? It’s probably something I am just not understanding correctly about moon rise and moon fall. Thank you!

    • Hi Diana! There were times we weren’t able to see the moon due to its location or marine layer of clouds covering the sky. Because we had been tracking it over time, we started to see a pattern and new which part of the sky it should be in on that particular night. We didn’t do it at the exact same time every night, but pretty close since we worked it into our evening/night routine. It was a super fun activity to do together as a family! Hope that helps! 🙂

        Maybe the difference is in where we live? In northeastern US, for the first part of September the moon was visible at reasonable times to look for it (say sometime in the window from 7 to 10 pm) for the 2 thirds of the month – either because it set in the evening/night and you see it before it set, or because it rose just before dark and you could see just after it rose. But by the 21th it rose later than bedtime (21st: 10:39pm, 22nd: 11:30pm, 23rd: 12:26 am … 30th: 6:24am) and set before dark the next day (21st: 12:12pm, 22nd: 1:17pm, 23rd: 2:26pm … 30th: 6:45 pm) so that for about a third of the month the moon was not visible during the window of say 7 pm to 10 pm. But even when it was visible during that window it was not always visible for the entire window – some days you could catch it early before it set or late after it just rose. Though frequently you can see it during the day time also. I’m trying to clarify for myself and others whether it is possible in all locations to see the moon every night at reasonable hours or at around the same time at night. I don’t know if I misunderstand the moon rise/moon set schedule or if things are different in different locations.

        • I am an elementary teacher. Twelve years ago, in my “How to Teach Science” class, the professor gave us a choice of assignments. The first was to put bread in a bag and observe the mold growth over two weeks. The second was to observe the moon for two weeks.

          I chose the mold project and at the end of ten weeks I had a mess that looked not only disgusting, but dangerous. When we shared out our results, the professor pointed out that some molds, such as black mold, can kill people, if not make them very sick.

          The moon project, others shared out, was very difficult for several reasons. Being in Chicago, it was hard to see the moon at certain times because of buildings and trees. At other times it couldn’t be seen for the reasons you stated. Other times it could be seen, but not all of my fellow teachers had the commitment to set their alarms for 3:15 am. A few did.

          Moral of the story? Assignments and projects must be done by the teacher before assigning them to little children. Otherwise you might put your students at great risk or give them an assignment that’s not feasible. And if your students live in a dangerous Chicago neighborhood, it really might not be responsible to ask them to go outside at a late hour. Most parents keep their children inside or might not take the initiative to go out with their child past their bedtime.
