# Mixing Colors of Light

Easy
Have you ever wondered what happens when you mix colors of light? In this project, you'll use flashlights and colored plastic sheets to find out! You'll attach a different colored circle of plastic sheet to each flashlight and beam light from two flashlights together to see what color is created. Then beam light from all the flashlights together into one spot. What color is created?

## Hypothesis

The hypothesis is that when red, green and blue light are mixed together, they will form white light.

## Method & Materials

You will use three flashlights and a square of blue, red and green plastic. You will attach a different colored circle of plastic sheet to each flashlight and beam light from two flashlights together to see what color is created. Then beam light from all the flashlights together into one spot.
You will need three flashlights or three slide projectors and red, green and blue plastic sheets.

## Results

The results of the experiment showed that when red, green and blue light are mixed together, they form white light. This observation stands out because it shows that the primary colors of light are different than the primary colors of pigments.

## Why do this project?

This science project is interesting and unique because it teaches students the concept of primary colors of light.

## Also Consider

Experiment variations to consider include using different colored plastic sheets or using different colored light bulbs instead of flashlights.
