Hands‑on science projects boost retention and spark curiosity. A simple styrofoam model of Pluto and its moons is an engaging way for students to explore our Solar System.

Step 1 – Gather Information

Verify facts before building. Visit NASA’s Solar System page for Pluto’s basic data, and consult NinePlanets.org for details on its satellites.

Step 2 – Select the Right Size

Pluto has one large moon, Charon, and two smaller satellites. Use one large styrofoam ball for Pluto, a second for Charon, and two smaller balls for the minor moons to reflect the relative sizes.

Step 3 – Paint the Model

Because no high‑resolution color images of Pluto exist, choose colors that represent its icy surface and the darker appearance of its moons. Creativity is encouraged.

Step 4 – Assemble the Moons

Insert a toothpick into each moon ball and thread the other end into the larger ball that represents Pluto. This creates the illusion of orbiting moons.

Step 5 – Mount the Model

Place the finished model on a stand for a freestanding display. Glue the styrofoam to a wine bottle, or attach it to a craft‑store base. If a stand is not needed, the model can be held while explaining.

Materials Needed

• Paint (acrylic or spray)
• Toothpicks
• Styrofoam balls – 1 large, 1 medium, 2 small
