Prepare live and dried plant materials such as moss, branches, gravel, clay, popsicle sticks and floral foam. Students select one element from their designs, i.e. garden path or a sculpture, to be used for a class model. Students define measurement terminology and use centimeter rulers to measure lengths and widths of class model and distances between objects. Divide class into small groups of four or five students. Rotating groups from station to station, students measure dimensions and record.
Students regroup to review and check results with a metric trundle wheel.
Using software, students create a garden layout by recording the dimensions and features of their rooftop garden. Community Activities Students make weekly trash collections. They also create and display posters encouraging the school community to refrain from littering, and pitch in to keep the garden clean.
