Merry-Go-Round Working Model for school science project exhibition

by

Introduction:

In this project, we will create a working model of a merry-go-round using a paper cup, DC motor, cardboard, and colored paper. The model will demonstrate rotational motion and how the merry-go-round operates using a motor to spin the platform.

Materials Needed:

  1. Paper cup
  2. DC motor
  3. Battery pack for DC motor (with switch)
  4. Cardboard
  5. Colored paper
  6. Hot glue gun or adhesive
  7. Craft supplies (markers, scissors, etc.)

Step-by-Step Explanation:

  1. Preparing the Base:
    • Cut a circular piece of cardboard as the base of the merry-go-round.
    • Attach the DC motor to the center of the cardboard using adhesive.
  2. Creating the Merry-Go-Round Platform:
    • Cut a circular piece of colored paper slightly larger than the paper cup’s mouth.
    • Attach the paper cup upside-down to the center of the colored paper using adhesive. This will be the platform’s central pole.
  3. Assembling the Platform:
    • Attach the colored paper with the paper cup to the DC motor’s shaft using adhesive. This forms the spinning platform.
  4. Decorating the Base:
    • Cut a larger circular piece of colored paper and glue it to the base as a decorative backdrop.
  5. Powering the Motor:
    • Connect the DC motor to a battery pack with a switch.
    • Turn on the switch to power the motor and spin the platform.
  6. Adding Details:
    • Use markers, colored paper, and other craft supplies to decorate the merry-go-round platform, base, and backdrop.

Demonstrating the Merry-Go-Round:

  • When you turn on the motor, the platform will start spinning around the central pole.
  • Explain that the rotational motion of the platform simulates the movement of a merry-go-round.

Conclusion:

By building the merry-go-round working model, you’ve successfully demonstrated the principles of rotational motion using a DC motor. This project highlights the fun and dynamic nature of merry-go-rounds found in amusement parks.
