Students can witness a population explosion right before their eyes as they nurture and experiment with living duckweed plants. Students start with a small number of plants and watch them reproduce vegetatively into a large matted colony, too numerous to count. Students can design their own experiments to determine factors that can affect the rate of the population explosion.
Complete with teaching suggestions and enoughmaterials for 30 students working in pairs. Lemna (duckweed) cultures are available separately.
