Educator How-To: Making the Moon out of Cheese (and Crackers!)

After months of renovation, the Burke Baker Planetarium at the Houston Museum of Natural Science will re-open March 11 with the best picture of the universe in the world! The Evans and Sutherland Digistar 5 digital projection system boasts the first True 8K image on the planet, with twice the resolution as an IMAX theater. The powerful digital software can zoom audiences to distant stars to see the universe from infinite perspectives, not just from the surface of the Earth. And with a tilted, seamless dome overhead and updated, comfortable seating below, the planetarium will be a must-see for Houston residents and visitors from literally anywhere.

But while it’s closed, life goes on, and without the incredible demonstration available at the planetarium to show the phases of the moon, explaining the orbit of our only satellite to kids (and keeping their attentions) can be a difficult task. So for hungry minds and bellies, we’ve got something to tide you over until the doors to the planetarium open once again.

Teach your students about the phases of the moon with this awesome Solar System snacking activity! I created this lesson plan as an alternative to the Oreo™ phases of the moon activity that we think is so clever. This science snack is a healthier alternative and will satisfy hungry students without the sugar rush. Educator How-To: Making the Moon out of Cheese (and Crackers!)

Moon phases


  1. Give each child a copy of the phases of the moon chart.  Go over the different phases, and consider using our Educator How-To: We’ll See You on the Dark (and Light and Far) Side of the Moon to demonstrate the phases in an active, hands-on fashion.
  2. Distribute one slice of American cheese to each student.
  3. Instruct students to carefully use the circular cutter to cut four circles from the cheese. With careful placement, one slice of cheese will be sufficient.
  4. Using a plastic knife, students will then cut one circle of cheese in half.
  5. The second circle will be cut using the circular “cookie” cutter.  Place the cutter carefully on the circle of cheese so that a crescent-shaped piece of cheese is cut from one side.
  6. The same procedure should be used to cut an additional crescent-shaped piece from the third circle of cheese.
  7. The fourth circle will remain whole.
  8. Now you are ready to go! Distribute the Phases of the Moon worksheets and have students place a Ritz™ cracker on each “moon.”
  9. Students will now arrange the cheese on the crackers to reflect each phase of the moon.
  10. When finished, students may eat the tasty moon snack!
