Creating a solar system working model with a big circle base, paper planets, a light bulb as the Sun, and a rotatable setup using a slow-running motor is a fantastic and engaging project.

Here’s a detailed guide on how to make this model:

Materials Needed:

  1. Large Circular Base: Use sturdy cardboard or plywood.
  2. Light Bulb: Small, low-wattage bulb to represent the Sun.
  3. Slow-running Motor: A motor with a gear reduction for slow rotation.
  4. Battery Pack: To power the motor and light bulb.
  5. Paper or Foam Balls: To represent the planets.
  6. Paint or Markers: For decorating the planets.
  7. Wire: For electrical connections.
  8. Switch: To turn the light bulb and motor on and off.
  9. Glue or Tape: For assembly.
  10. Scissors and Craft Knife: For cutting.
  11. Ruler and Compass: For measuring and drawing circles.
  12. Small Rods or Dowels: To mount the planets.
  13. Hot Glue Gun: For securing parts.

1. Prepare the Circular Base:

  • Cut out a large circle from cardboard or plywood. This will be the base of your solar system model.
  • Optionally, paint the base black or dark blue to represent space.

2. Create the Planets:

  • Use paper or foam balls of different sizes to represent each planet.
  • Paint and decorate the planets to resemble their actual appearance. Refer to images of the planets for accuracy.

3. Mount the Light Bulb (Sun):

  • Securely attach the light bulb at the center of the circular base.
  • Connect the light bulb to the battery pack using wires, ensuring you include a switch in the circuit to turn the bulb on and off.

4. Attach the Motor:

  • Mount the slow-running motor under the base, ensuring the shaft extends through a hole in the center of the base.
  • Attach a small platform or disc to the motor’s shaft to hold the rods or dowels for the planets.

5. Create Planet Arms:

  • Cut small rods or dowels to different lengths to hold each planet.
  • Attach one end of each rod to the small platform or disc on the motor’s shaft. The other end will hold a planet.

6. Secure the Planets:

  • Attach each planet to the end of its respective rod using glue or tape.
  • Ensure the planets are spaced correctly to represent their positions relative to the Sun.

7. Connect the Electrical Components:

  • Connect the motor to the battery pack, including a switch in the circuit to control the motor.
  • Double-check all connections to ensure they are secure and safe.

8. Final Assembly and Testing:

  • Place the circular base on a stable surface.
  • Turn on the switch to power the light bulb, representing the Sun.
  • Turn on the motor to start the slow rotation, making the planets orbit the Sun.


This working model of the solar system is a visually engaging way to demonstrate the planetary orbits around the Sun. The combination of a light bulb, rotating motor, and decorated planets makes for an educational and impressive project. Enjoy building and displaying your solar system model!
