Science Project for Mixing Colors
- If your child is in primary school, you'll want to choose a project that helps him understand what color is. This can be done by placing filter paper on a plate and then placing a candy such as Smarties on the paper. Have your child slowly drip water onto a single Smarties and watch a ring of color appear around the candy. This will teach him that different dyes can make up one Smarties color.
- A fun science project for elementary school students is to discover how milk and food coloring mix. Fill the bottom of a large plate with milk. Add one drop each of yellow, red, blue and green food coloring. Touch the tip of a cotton swab to the center of the milk without stirring and watch the chemicals of the ink bond. Now add a drop of soap to the other end of the cotton swab and touch the milk to watch the colors explode. This will show students how molecules bond.
- For middle school students, test out color-mixing projects by investigating how the weather changes the colors of sunrises and sunsets. To do this, record both the mix of colors in the sunset, the vibrancy of colors and the weather patterns each day for 30 days. The results after 30 days should show you which weather patterns cause specific color mixtures in the sky. Another project is to attempt to determine if different brands of markers have the same color mixtures using a tool such as chromatography paper.
- For high school students, one project idea is to determine how mixing colors and chemicals can change the color of hair. To do this you will need hair swatches and peroxide-based hair dying materials. Consult with a salon or an adult on what materials to purchase to dye hair. Try mixing the chemicals to form different colors. Always use protective gloves and do this project in the presence of an adult. This project will also teach students how pH levels work in lightening and darkening colors.
