Can plants really grow without soil? Your class will be fascinated as they compare the advantages and disadvantages of both hydroponic cultivation techniques and traditional means. For each cultivation method, they will compare the rate of germination and growth as well as the development of the stems and leaves. They’ll even compare the plants’ roots growing in the clear containers included. The class will also observe and contrast the physical characteristics of plants grown in various nutrient solutions to determine the ideal growing conditions for a hydroponic environment. For a class of up to 40 students. Grades 5-12.
