"'Trees' helps develop language skills and teaches eleven vocabulary words in many visualized situations. The lesson consists of scenes visualizing all aspects of a tree's growth and development--seed, roots, trunk, branches, and leaves. Air, food, water, and sunlight are described as being necessary for a tree to survive. The various ways that trees help us, and the products they provide, are shown. Conservation of our forests is stressed as an optional folk song provides much of the narration."--1971 Peabody Digest. The ending of the program has a vocabulary fill in the blank exercise for viewers.
