Curtis is embarrassed to be dressed like a tree for a school play. Barney assures him that it's a terrific role and hopes Curtis will feel the same way when he learns more about trees. Barney and the children learn about trees' need for water and sunlight. They also learn that trees remain healthy even when the leaves change color and drop off in the Fall. The Adventure Screen shows many different types of trees in different environments. The children are surprised to discover how many of their favorite foods and products come from trees. This leads to a discussion of a lumberjack's job, and Barney tells the fantastic tale of Paul Bunyan. Scooter and Miss Etta tell the children that trees are often homes for different animals. Barney reminds the children that everyone should help save trees by recycling. In the end, Curtis has an entirely new outlook about his role in the play.
