Science Fair Project Idea
Did you know that mixtures can be unmixed? Chromatography is an analytical technique in chemistry to separate mixtures and identify each of its individual compounds. In this project, you will separate ink dyes found in different markers using a strip of paper, chalk and different liquids. By comparing different chromatography substrates and solvents, you will learn how different attractive forces between substances can affect the separation of a mixture into its individual components.

Have you ever looked at sunlight through a prism? If so, you know that the prism can separate the sunlight into many different colors of light — a rainbow. Like sunlight, chemical mixtures can also be broken into their component parts. One way of doing this is a simple technique called paper chromatography. What do you think you will see if you use paper chromatography to look at the components of black ink? Is black ink just black? Find out for yourself! Read more

Science Fair Project Idea
Although fractal images can be intriguingly complex, fractals are more than just pretty pictures. In this project, you'll explore the mathematical properties of the famous Mandelbrot (illustration on the Background tab) and Julia sets. You'll learn about how these images are generated, and about the relationship between the Mandelbrot set and the Julia sets. Read more

Have you ever wondered why a water strider can walk on water? Or how detergent can clean your dishes? If you observe carefully, you can find dozens of similarly interesting phenomena that are all linked to the surface tension of water. In this science project, you will investigate the properties of water surface tension. Read more

Have you ever heard about different blood types? Do you know what your blood type is? Antibodies help scientists determine different human blood types. This project is a practical introduction to the human immune system in which you will learn about what antibodies are, how they are formed, and how they can be used to identify different types of cells.

This is an interesting project that explores which geometrical shapes make the strongest bridge truss structures. It is a good introduction to the engineering design process. You'll design three different trusses, and use online simulation software to analyze the distribution of load-bearing forces in each design. Then you'll build and test prototypes of each design.

Science Fair Project Idea
The Wright brothers used kites extensively to test their design ideas in the years leading up to their first successful airplane flight. With this science project, you'll learn about kite aerodynamics, and then come up with your own hypothesis about building or flying a kite. You can test your hypothesis two ways: with an online kite simulation program from NASA, and outdoors with the real thing! A great feature of this science project is that it has many possible variations, so you can decide… Read more

Science Fair Project Idea
Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether the kid standing next to you is your sister or your cousin? The biologist might be able to make some good guesses this way, but by using samples of your family's DNA, s/he could construct your whole family tree. In this project, you'll use a Web-based… Read more
