Solar System Projects: Mini Clay, Paper Mache, and Yarn Ball
Planet and Solar System Models
Making an artistic model of our solar system can be simple enough for a preschooler or advanced enough for older kids, teens, and adults. The three science project ideas in this article can be used for almost any age level, as you can keep the creations very basic or venture to the more elaborate. The learning concepts you add can be as straightforward as the names of the planets or as complex as calculating planet rotation rates. These are fun and cool space projects that everyone will enjoy. As an added bonus, the artwork is so special that you will want to keep it as a table-top or room decoration.

How to Make a Mini Clay Solar System
My 12-year-old daughter is a mini clay food artist, so I commissioned her to use some basic clay techniques to make a mini solar system for the above video. The methods she uses are easy to learn. Some that she demonstrated are:
- using craft sand for texture (Sun)
- using a ball tool to create craters (Mercury)
- twisting and folding clay for a swirled effect (Venus, Mars and Saturn)
- cutting out clay shapes (Earth and Jupiter)
- scraping powder from chalk pastels to add another layer of color (Uranus)
- mixing two clay colors for a marbling effect (Neptune)
Using the video tutorial and the instructions below, you can make your own mini clay solar system.
- tile, cutting board, or other smooth surface to work on
- oven-bake polymer clay: black and assorted colors
- orange craft sand
- royal blue chalk pastel
- clay tools* - ball stylus tools, clay cleaning tool (looks like a mini chisel), clay blade, mini circle cutter
- small paintbrush
- black floral wire
- wire cutters*
- parchment paper
- cookie sheet
*Younger children will need adult supervision with any sharp tools.
- Create the sun, base, and 8 planets as shown in the video. The chart to the right will give you ideas for clay colors and techniques you may want to use to create your own planet designs.
- The planets will be attached to the black base with the floral wire, so cut 8 pieces of wire in ascending lengths as shown in the picture below. Mercury will be attached with the shortest wire, and Neptune will be attached with the longest to represent each planet's distance from the Sun. The other planets should also be paired with the corresponding wire length.
- Using pliers, bend one end of each wire up (about 1/2 inch) to form a right angle so that it will hold a clay planet.
- Follow the layout of planets in the thumbnail picture to the right or play around with your own design.
- Once you decide which order the planets will be placed, stick the shortest wire in the base and attach Mercury to the other end. Attach all the other wires and planets. If one side of the model is leaning over, you may have to rearrange the planets and wires.
- Before baking, remove the planets from the wires and set aside with the Sun. Place the black base with attached wires on a cookie sheet lined with parchment paper. Follow the baking instructions for the clay you are using. (We used Sculpey clay and baked for 15 minutes at 275 degrees.)
- Let the base cool, and then add the planets to the wires. Place the Sun on the cookie sheet, but not on the base. Again, follow baking instructions for the clay you used. (We baked for 15 more minutes at 275 degrees.) Let cool.
- Once the solar system model is cooled, you can add the sun to the base. For extra durability, glue the sun to the base.
Paper Mache Planets
You will need:
- old magazines or newspapers
- large bowl or tray
- whisk or large spoon
- acrylic paint, assorted colors
- paint brush

How to Make Paper Mache Planets
Amazing pieces of art can be made from the simple ingredients of paper, flour, water, balloons, and paint. Round planets are the perfect subject for a basic paper mache. Who doesn't love tearing paper, feeling the gluey goo, and painting? It is a messy, long process, but the results are spectacular. The finished products can be suspended from the ceiling in your child's bedroom, in planet order of course.
- Blow up eight balloons in sizes to represent the eight planets.
- In a large bowl or tray, mix flour and water into a soupy glue-like substance.
- Mix in a little salt to prevent molding.
- Tie a piece of string to the knot of one balloon.
- Rip magazine pages or newspaper into 1 1/2 inch wide strips of varying lengths.
- Soak a strip of paper in the flour mixture and wipe excess liquid off by sliding between your fingers or between your finger and the side of the bowl or tray.
- Apply the wet strip to the balloon.
- Continue to add soaked paper strips until the balloon is completely covered.
- Hang balloon from a rod to dry. Protect the floor with paper or an old bed sheet.
- Repeat Steps 4-9 for each balloon. Let dry for 24 hours.
- Repeat process and add a second layer of paper to each balloon. Let dry for 24 hours.
- Repeat process and add a third layer of paper to each balloon. Let dry for 24 hours.
- Paint each balloon to resemble the planet it represents.
- The rings of Saturn and Uranus can be painted on or made from poster board. (We painted rings directly on Uranus, but painted striped rings on poster board for Saturn.)
- Let planets dry for 24 hours, and then pop the balloons with a pin near the balloon knot.
- After blowing up the balloons, write the name of each planet on the balloon to keep them straight. Hang the planets to dry in order as well..
- For the last layer of paper mache, use plain white copy paper so less paint will be needed.
- Metallic and glitter acrylic paints work well for this space project.
- If you hang your completed planets from the ceiling, use fishing line string which is almost invisible.

How to Make a Yarn Ball Solar System
Yarn or string balls make beautiful holiday ornaments, but they also make really cool planets. To display this decorative project, hang the Sun from the center of a large round piece of cardboard. Hang the planets in orbit around the Sun. Another idea is to hang them from a wooden dowel in planet order from the Sun. Follow these instructions to create a fantastic yarn ball solar system:
- yarn, assorted colors
- water balloons or other small balloons
- tacky glue
- large bowl or tray
- glitter, assorted colors
- wax paper
- Blow up 9 balloons to represent the Sun and 8 planets.
- In a bowl or tray, mix glue with a little water to make it runny.
- Paint a balloon with the glue mixture.
- Twirl a piece of yarn around the balloon knot and hold in place.
- With your other hand, wrap the yarn around the balloon criss-crossing vertically many times.
- Start wrapping horizontally and then in all directions until the balloon is mostly covered.
- Tie yarn in a knot with the starting yarn piece near the balloon knot.
- Leave enough excess yarn so you can hang the balloon up to dry.
- Soak the yarn covered balloon in the glue mixture. Use a paintbrush to dab and saturate thick areas of yarn.
- Sprinkle glitter all over the yarn ball.
- Hang to dry over wax paper to protect your floors.
- Repeat the process for all the balloons.
- Let dry for 24 hours.
- Once completely dry, pop the balloons with a pin or toothpick.
- Remove balloon pieces with your fingers or tweezers.
- To create Saturn's rings, follow the step-by-step pictures to the right.
