Trees Overview




The giant sequoia is the most massive living organism on Earth. It is a tree, magnificent in dimension and awe inspiring in its longevity and durability. To stand in the company of such giants is to experience the scale of life.

To a kindergartner the oak on the corner, the pines at the park, and the mulberry trees at school are giants. Systematic investigation of trees will bring students to a better understanding of trees’ place at school and in the community, and will provide some solid experiences on the way to understanding all plants.


  • Develop a growing curiosity and interest in the living things that make up their world.
  • Observe and describe the properties of trees and leaves in the schoolyard.
  • Compare the similarities and differences of the trees and leaves observed on mini–field trips.
  • Help plant and care for a tree temporarily in the classroom, then permanently in the schoolyard.
  • Observe trees throughout the school year for changes that come with the different seasons.
  • Compare the shapes of leaves to geometric shapes.
  • Compare the size and edges of leaves, using a reference card.
  • Use pictorial experiences to heighten their awareness of the diversity and variety of trees and leaves.
  • Acquire the vocabulary associated with the properties and structures of trees and leaves.
  • Use drawings and oral language to describe observations.
