The Electric Motor Model with Newton Color Disc is a fascinating educational tool that combines physics and color theory. Let’s explore its purpose and how it works:

1. Newton’s Disc:

   • A Newton’s disc, also known as a disappearing color disc, consists of colored segments arranged like a pie on a rotating disc.
   • When spun rapidly, the primary rainbow colors blend together, creating the illusion of a white disc.
   • It beautifully demonstrates how white light is composed of various colors.

2. Hypothesis:

   • When you rotate a Newton’s disc using a toy motor, the colored segments on the disc (made of cardboard and pencil colors) blend together.
   • The result is a near-white shade due to the mixing of different primary colors.
   • Although the complete white color isn’t realized due to impurities in the colors, the effect appears as a muddy white.

3. Materials Required:

   • To create your own electric Newton’s disc, gather these simple supplies:
     • Equivalent-sized piece of cardboard
     • Glue
     • Tape
     • Scissors
     • Standard printer paper
     • Color pencils (choose rainbow colors)
     • Coloring sources (sketches, color pastels, watercolor paintings)
     • Ruler
     • Toy motor
     • Drawing compass (or any round object for tracing)

4. Step-by-Step Instructions:

   • Prepare the Disc:

     1. Draw a circle on the cardboard using a rounder.
     2. Divide the circle into 7 equal parts using a protractor.
     3. Color each segment with VIBGYOR colors (violet, indigo, blue, green, yellow, orange, red).
     4. Cut out the disc using scissors.

   • Assemble the Motor Model:

     1. Attach the colored disc to the toy motor.
     2. Connect the motor terminals to a power supply (DC).

5. Observation:

   • When you turn on the motor, the colored segments blend as the disc rotates.
   • Due to the persistence of vision, our eyes perceive a near-white color as the primary colors mix.

6. Science Behind It:

   • Colors depend on light, and any object appears colored based on how it interacts with light.
   • Sunlight, our primary source of colors, contains a spectrum of colors.
   • Light travels as energy, and when you spin the Newton’s disc, the colors merge into white due to the rapid blending effect.
