Explanation of Color From a Prism

Although no one knows who invented the prism, Sir Isaac Newton was the one who discovered that the rainbows they produced were merely the components of white light that had been separated.

What is White Light?

Usually just called light or “visible light,” white light comes from the sun. It can also be produced by incandescent light bulbs, fires, or anything that gets hot enough to emit visible light.

How White Light becomes a Rainbow

When light shines through a prism it enters at an angle and exits at another angle. Different frequencies (color) of light are refracted at slightly different angles when they enter and exit the prism at an angle. Refraction is the change of direction that occurs when any type of wave goes into a different material at an angle.

Because the diffraction angle is different for different colors, the white light gets separated into different colors as it passes in and out of the prism.

What Colors come from a Prism

Although people can perceive around 10 million colors, prism colors are classified as one of the following seven:

  1.    Red
  2.    Orange
  3.    Yellow
  4.    Green
  5.    Blue
  6.    Indigo
  7.    Violet

How to get a Bigger Colors from a Prism

The further away the prism is from the target surface, the larger but also dimmer the colors will be. If you have a dark room and a bright sun, it will show up beautifully at a distant wall.

The closer to the prism the more brighter and bunched up the colors become. If you get too close to the prism then you will not be able to distinguish the colors anymore.

Color Lessons for Children

Catch the Rainbow.

Younger children love to chase the rainbow along the wall and around the room as you tilt the prism. They will try to catch the rainbow in their hands.

Share observations.

Children of all ages can make observations of the prism’s rainbow. Preschool children, like the 2- and 4-year-old pictured here can describe what they see. Ask if they hear, smell, or feel the rainbow.

For older children, ask if the colors are in separate bands or if they run together. Is each color equally wide, or are some wider than others?

Color what you see.

Have the prism shine onto a table or other solid surface, provide a variety of crayons and have them color what they see or color around it.

Test different light sources.

Try a strand of colored Christmas lights–what colors come out of the prism? What about that yellowish light in the lamp? Or a black light?

If using Sunlight

Keep in mind that the earth is rotating, so if you are using sunlight the color will move and you may have to readjust the prism for maximum color and shape.

The Effects of Temperature on Water Absorption in Warblettes

In this experiment, we are going to determine the effect of temperature on water absorption in warblettes.

To complete this experiment, you will need the following:


1. Create an ice bath by placing a mixture of water and ice in the 500 ml beaker. Fill approximately 1/2 full.

2. Using a graduated cylinder, pour 50 ml of water into one of the 250 ml beakers. Place the beaker in the ice bath. This will keep the water cold during the experiment. For the purpose of this experiment, it will not be necessary to measure the actual temperature of the water. Our main goal is to compare cold and warm temperatures in general. The water will drop to between 5 and 10 degrees celsius.

3. Using a 50 ml cylinder, add 50 ml of hot tap water to the second 250 ml beaker. The water temperature will be approximately 40 degrees C and will continually cool during the experiment.

4. Add 40 Warblettes to each of the 250 ml beakers. Allow the Warblettes to absorb water for 20 minutes.

5. Take one beaker and pour the remaining water into the graduated cylinder. Measure this amount and subtract from the original 50 ml. This calculation will give you the amount of water absorbed by the Warblettes. Repeat this step for the second beaker.


The warmer temperature water will promote faster growth of the polymer. Compare this to real life applications like:

  • Coffee, tea, sugar, and other solids dissolve faster in hot water.
  • Most bacteria grow best at warmer temperatures (close to human body temperature).
  • Ice on a contusion reduces bruising by slowing blood flow.

Warblettes can be used in many experiments and create interest and excitement while reinforcing scientific principles.


The Physical and Metaphysical Properties of Fluorite

Fluorite is an isometric crystal composed of Calcium and Fluorine (CaF2). This mineral was first identified in 1529 and has been credited with having many healing properties. The name is derived from the Latin, fluere, meaning “to flow.” This is due to the relatively low melting point of 2557 degrees F. Fluorite is used in the steel production to decrease the viscosity of slags and eliminate impurities. It is also used in the manufacturing of some glassware and polymers and enameling cookware. Fluorite is found in many places including the U.K., Mexico, Morocco, Peru, Brazil and the U.S.

Physical Information

Color: white, green, purple, yellow, blue, gray

The color of the specimen is determined by impurities that have replaced calcium in the crystal structure and the presence of hydrocarbons (petroleum). Pure form is clear(white).

Hardness: 4

Class: Halides

Fluorescence: Many specimens are fluorescent under UV light.

The phenomenon of fluorescence received its name from this mineral.

Density/Molecular Weight: 3.18 g/cm3   /   78.07 g


Fluorite is credited with having many spiritual and physical healing properties ranging from easing the pain of arthritis to reducing nervous energy. The healing properties are largely determined by the color of the specimen.

Green absorbs excess energy, allowing for information from the subconscious to be moved to the conscious mind. Helps egocentric problems and heals stomach and intestinal illness.

Purple stimulates wisdom and the ability to discriminate, allowing for the promotion of spiritual vision. Useful in healing issues related to bones, marrow, and the spine.

White brings spiritual and mental harmony. Brings peace and strengthens awareness. Aligns all of the Chakras.
