How can a butterfly start a hurricane? Why does a snowflake grow in the shape it does? Why do populations of animals change in seemingly random ways? Or, for that matter, is the throw of a dice really random?

Some of the most interesting studies in modern science and mathematics have to do with things we cannot predict. The descriptions include words like chaos, randomness and fractals.The goal is to learn about the science and mathematics of chaos and how it operates in our world.

The activities listed here were performed by students in the 1999 and 2001 Student Science Enrichment Program (SSEP) at The Science House funded by the Burroughs Welcome Fund.
