Developed by Donna Bozzone, Saint Michael's College. Dictyostelium and related organisms have an unusual life cycle during which they exist as independently feeding amoeboid cells that can aggregate to form multicellular bodies. Students explore the life cycle and investigate factors that trigger the development of its different stages. They can also design experiments to test how cells choose between developmental pathways, the behavior and biology of the multicellular stages, how different species of cellular slime molds interact, and many other questions. Includes teacher instructions and suggestions for further inquiry. Kit contains coupon for prepaid delivery of perishable materials.
