Bored at home? Want to enjoy cool science experiments and also learn English?
Yala, let's get started!
The experiment ahead of you
Color (Vision)
:Objective
Understanding that colors are part of the visible light spectrum
:Introduction
Visible light is the fraction of the electromagnetic spectrum that the human eye can perceive and translate into images
These wavelengths are in the range of 390-750nm. After coloring the disc and spinning it fast enough, our eyes cannotprocess
the colors fast enough and our brain therefore processes the color as an average of white
:Experimental method
:Newton’s disc
- Cut paper into discs.
- Divide disc into 6 or 12 equal parts.
- Color each part in a different color by order: purple>blue>green>yellow >orange>red. Make sure the color is pale.
- Insert toothpick into center and stabilize with plasticine.
:Color assembly
- Cover each flashlight with one color of cellophane plastic.
- Shine light on white wall or paper. See color of each light.
- Shine different color lights in the same place simultaneously. See the colors that are created
List of equipment:
- White paper circles
- Colored pencils or crayons.
- Toothpicks
- Plasticine
- Scissors
- Ruler
- Pure color cellophane plastic: red, blue and green.
- Three white flashlights.
- Rubberbands
