Fun Kids’ Activity from the Experts in Education

This guest post is being brought to you by the amazing staff at

Let me start by saying that I was beyond honored when Jessica reached out to me inquiring about posting guest content on the DisorientedMom site.  I researched the site and am very impressed by what I see.  They have a team of experts that work with teachers and curriculum developers to create educational activities and a vast number of resources for kids.

The particular project being shown here is a science experiment, which my daughter happens to love.  In school, science experiments are one of the few things she looks forward to, so her and I will be doing this one together as well.

The project is listed below, and can be found on the website directly at .


Science Project: 

Can White Light Be Separated?

Third Grade Science Science Projects: Can White Light Be Separated?

Research Questions:

  • Why does a prism create a rainbow from white light?
  • What are the colors of the rainbow?
  • How do you think a natural rainbow is created?

The visible spectrum is the portion of the electromagnetic spectrum that can be seen by the human eye. It consists of seven spectral colors: red, orange, yellow, green, cyan/indigo, blue, and violet. These colors are what you observe when you see a rainbow. These colors each have different frequencies and wavelengths; red having the longest wavelength and violet having the shortest.


  • Flashlight with white light bulb
  • A piece of cardboard opaque enough to block light
  • Hole punch
  • A glass prism (can be obtained at a science store)
  • Paper nd pencil

Experimental Procedure

  1. Punch a hole in the cardboard.
  2. Place the prism on a flat surface.
  3. This experiment will look best when done in the dark or under dim lights. Turn on your flashlight and shine it on the cardboard through the hole and direct it at the prism. What do you see?
  4. Now place a second prism in front, but at a slightly different angle than the first one. What happens?

Terms/Concepts: Visible spectrum; Electromagnetic spectrum; A few glass or plastic prisms; White light

  2. My son is getting to a stage where he enjoys little science experiments (read: kitchen experiments – he loved baking soda and lemon fizzing!) so this sort of little project might be just a thing for him! Thanks for sharing 🙂
