Pattern formation

The pattern formation lab deals with spontaneous pattern formation in standing cultures of Tetrahymena. The honeycomb patterns formed in standing cultures of Tetrahymena have been linked to convection, chemotaxis, and cell-cell interaction, making this module not only useful as an independent biology lab but also potentially interesting as a cross platform vehicle for linking biology, math, and physics. Since various conditions affect spontaneous pattern formation and reaggregation, including media, cell density and environmental conditions, the lab lends itself to independent student inquiry and experimental design.
