Students list all they know about any plants found on the school grounds. Working in pairs or small groups, students identify certain plants. The groups research the plant and discover any benefits to man, any diseases, history, whether it is native to the area, etc. Students learn how to age deciduous trees and conifers. Each group writes a narrative and draw or find pictures about their plant.
Students publish their book and make several copies.
Students give guided tours of the school area to other classes, parents, and any interested community groups. The culmination of this unit would be giving guided tours using their published guidebook. Include insects and other animal life. Plant another tree or bush of a species not found on the playground.
