This video provides a real-life example of the scientific method: testing hypotheses about which plants will grow most successfully on a green roof in Kentucky. At Bernheim Forest near Louisville, scientists have set up 12 roof grids at ground level. The roof grids are filled with three different kinds of growing media and planted with four different groups of plants to determine which plants and media would work best for the Visitor Center roof garden and other roof gardens in the region.
