Oscillating chemical reaction is thought to be the key to many regulatory processes in living cells, such as the mechanisms that turn on and off the enzymes that transcribe DNA or the contraction of a muscle. The BZ reaction has been the subject of on-going research in chemistry, dynamical systems, and math biology. Our project is to quantify the chemical oscillation in the well-stirred BZ reaction, and visualize the pattern formation due to the instability of traveling chemical fronts in the non-stirred BZ reaction. Experimentally we follow several recipes for the well-stirred BZ reaction, each group of students has their own. For the non-stirred BZ reaction we use the package from "Science Kit and Boreal Laboratories".Click here for more detail.
