Phases of the Moon STEM Activity + FREE Printable


Students in second and third grade are often introduced to the basics of
astronomy in science class. They learn about how Earth rotates on its axis every
24 hours causing night and day and how a year is measured by its revolution
around the sun. They learn about how the moon revolves around Earth every 29.5
days and its effect on the tides. And, they learn how sunlight reflecting off
the moon’s surface and Earth’s shadow interact to cause the phases of the moon
that we see at night. The STEM minilesson below can be used to enrich your
science and STEM lessons and activities about the moon. Keep reading to learn
more!

Science and STEM craft for children. Students will  use Oreo cookies to create a model of the phases of the moon. Second, third, and fourth grade.


What are the phases of the moon?

When learning about the phases of the moon, students need to remember the names
of each phase, the sequence of phases, and what each phase looks like. It can be
a lot for the students… and some teachers… to remember! The phases of the
moon starting with the new moon are:

  • new moon
  • waxing crescent
  • first quarter
  • waxing gibbous
  • full moon
  • waning gibbous
  • third quarter
  • waning crescent
  • new moon (sometimes called dark moon)

Reminder: When the moon waxes, we see more of its surface
each night. Once it starts to wane, we see less of its surface.

Is the moon waxing or waning in this photo?

Phases of the Moon + Oreo Cookies STEM Craft 

Using Oreo cookies to create models of the moon’s phases is a popular science
and STEM activity among teachers and students. For decades, teachers have used
this as a culminating activity to enrich their students’ new knowledge. Very
few materials are needed for this activity and can be purchased inexpensively
online.

Materials Needed

It’s not easy to scrape 100% of the filling while carving each phase of
the moon with a toothpick. If some of the filling remains in the small
cracks and crevices of the cookies, please don’t penalize the children
for it.

 

Directions

  1. Review the eight stages of the moon, their sequence, and what they
    look like.
  2. Each student will need a minimum of eight Oreos and a toothpick. They
    can use their own white glue.
  3. Pass out the phases of the moon printable below, one per student.
  4. The students are to break open each Oreo and use their toothpicks to
    carve out the shape of each phase of the moon in the filling.
  5. The students then use their white glue to glue their Oreos moons to
    the printables.
  6. Let the glue dry completely before sending this STEM craft home.

Free Phases of the Moon Printable

Each student will need their own copy of the printable below. For best
results, I suggest printing this on
white cardstock.
