Get pictures of Uranus. Study the composition of the planet, its tilt and why it looks the way it does.
Spread newspaper on a work surface.
Inflate a balloon until it is 5 inches in diameter. Mix three parts glue to one part water in the bowl. Cut newspaper into strips. Dip a strip of newspaper into the glue and water mixture, and apply it to the balloon. Coat the entire outside of the balloon with more glue covered strips of newspaper. Set the balloon aside to dry.
Make the ring system. Measure the diameter of the dried papier-mache sphere.
Draw a circle that is slightly smaller than this diameter on the card stock. Measure 2 inches out from this circle, and draw another circle. Cut out the both circles. Set the inner circle aside.
Draw the rings of Uranus onto both sides of the card stock ring with the colored pencils, keeping an eye on the Uranus pictures for reference. Slide the card stock ring onto the papier-mache sphere, making sure not to squash it. If it is too snug to fit properly onto the papier-mache sphere, cut a little out of the hole and try sliding it on again.
Hold the model so that it tilts in accordance with Uranus's axis. Poke two holes approximately 1/2 inch apart on the "top" of the model with the curved upholstery needle. Thread the curved upholstery needle with a length of string, passing it down one hole and back up the other. Tie the ends of the string together.
Paint the model to look like Uranus, again using the pictures as a reference, and hang it up over newspaper to dry.
