Earth & Sky

Never underestimate the power of a tree! Besides giving us an amazing array of paper and wood products, trees provide a host of other benefits – from shading our backyards to assisting in the maintenance of the global climate. Students can express their appreciation of trees by planning and carrying out their own tree-planting project.
