The Topic: 
Fractals

Easier - A fractal is a shape, often drawn by a computer, that repeats itself in a pattern. The design shapes usually reoccur in different sizes.
 
Harder - Fractals are endlessly repeating patterns that vary according to a set formula, a mixture of art and geometry. Fractals are any pattern that reveals greater complexity as it is enlarged A real-life example of fractals is ice crystals freezing on a glass window. You can see countless variations of the same pattern emerge in the crystals over time.

Fantastic Fractals by J. Sheu and M. Turvey
http://www.techlar.com/fractals/websys.exe?file=index.html
This comprehensive site on fractals first began as a ThinkQuest project. It still includes a kid's section that uses audio clips to explain the basics of fractals in an interesting manner, and the rest of the site has just about any fact or explanation a high school student might need on the topic. Also has quizzes, downloadable files, links, and more.

Make Your Own Fractals. You might want to start at The Sierpinski Triangle, The Jurassic Park Fractal, and The Koch Snowflake at Cynthia Lanius's Fractals website. Then go to one of the online fractal generation programs. The IFSoft Home Page has two Java applets: fractalina, a program for making fractals; and franimate!, a program for animating fractals. You also can try Make Your Own Julia Set at The Fractory. Follow up by using the 'Make-Your-Own Mandelbrot Set" at the same website. Compare the fractals that you make. Try using the same parameters. Read the 'learn more' and 'how the fractals are generated' sections.
 
Create Some Fractal Music. Visit Fractal Music to begin learning about fractal music. Then go to the program set at Create Your Own Chaos and compose some of your own fractal music.
 
Play An Online Fractal Game. Go to the Leap Fractal Game and follow the provided rules. This is an interactive fractal game that gives the player a choice of three different games and each game can be played at four different skill levels - - Requires Java.

Making Order Out of Chaos (1997 ThinkQuest Internet Challenge)
http://library.advanced.org/12170/
The most well-known aspects of chaos theory are fractal images. Fractals appear to be complex and hard-to-comprehend at first glance, but the underlying code is very simple.

Fractal Music: The Sound of Chaos 
http://www.discovery.com/stories/technology/fractals/fractals.html
Nowadays, the mathematics behind fractals is better known as chaos. An amateur musician creates his music using nothing more than a desktop computer and a mathematical entity called the Mandelbrot set, a simple equation better known for generating complex and haunting fractal images. (Requires Real Audio program, free download link provided)
