A presentation for elementary and secondary students introducing them to trees.  

The presentation begins with the physical traits of a tree versus a bush and as compared to a human.

Students will learn about the difference between deciduous versus coniferous trees and the shapes of simple single blade and compound leaves.

A series of photographs will guide the student through the characteristics of deciduous trees - loosing their leaves in winter, sap tubes closing ending a leaf's water supply, the cold weather causing green chlorophyll to uncover brilliant pigments of yellow, orange and red.

Students will discover that deciduous trees flower in the spring.

Next, students will learn about coniferous trees and that they have cones and needle-like leaves.  Several examples of evergreen trees are provided.

Both coniferous and deciduous trees are now discussed in relation to the importance and function of root systems.

The various layers of a tree's trunk is reviewed as is how the layer of bark grows.

Photographs illustrate the function of leaves and students will learn about photosynthesis.

The buds of trees are reviewed and students will learn about resting winter buds, scale-like coverings, and the transfer of pollen.

Finally, various types of forests are shown to illustrate that not all trees have the same length of growth habits.  Students will learn about the uses of trees and resources obtained from them including lumber, fruit and nuts.

The presentation ends with some illustrations of how animals interact with trees and dangers that trees are subject to such as fire, wind, insects, fungi, smothering and animals.

New terms:  perennial, diameter, trunk, deciduous, coniferous, simple, compound, blades, chlorophyll, pigment, pollination, needles, scales, cones, foliage, cambium, sapwood, heartwood, stamen, pistil,
