Activity #6

Focus:
An awareness activity concentrating on common terms used in forestry.

Materials:
• Sheet of forestry terms and their definitions.
Crossword puzzle, Crossword Clues

Procedure:
Pass out sheet of forestry terms and crossword puzzle.

After all the students have completed the puzzle, ask if anyone can embellish on any of the terms that were given.

Ask if anyone knows any words that could be added to the sheet.

Have the students share their information with the rest of the class.


Forestry Terms-
Here is a list of some common forestry terms

  • annual: A plant that completes its entire life cycle in a single growing season. Tomatoes, daisies, and peas are examples of annuals.
  • annual ring: The ring that can be seen in a cross-section of a tree. These rings show the age of the tree.
  • bark: The outer layer of the trunk and branches that helps protect the tree from injury and disease.
  • biennial: A plant that lives for two growing seasons, producing only the leaves during the first season and the flowers and seeds during the second.
  • cambium: The thin layer of cells between the phloem and the xylem that makes the trunk, branches, and roots of a tree grow thicker.
  • canopy: The uppermost layer of most forests. The branches and leaves of the tallest trees form the canopy.
  • conifer: A plant that bears its seeds in cones.
  • deciduous: Trees that lose all of their leaves each year. Maples, ashes, oaks, and dogwoods are examples of deciduous trees.
  • dendrology: The study of trees.
  • evergreen: Trees that do not lose all of their leaves each year.
  • forestry: The science of managing forests.
  • habitat: The native environment of an animal or plant. The kind of place that is natural for animal or plant.
  • hardwoods: Broad-leaved trees.
  • heartwood: Sapwood that has become filled with resin-like material and no longer transports water and minerals. Also called old xylem.
  • perennials: Plants that live for many seasons. Trees are perennials.
  • phloem: A pipeline of cells that transports the sugars (carbohydrates) produced by the leaves to the rest of the tree. It is also called inner bark.
  • photosynthesis: The formation of carbohydrates in the chlorophyll-containing tissues (especially the leaves) of plants exposed to sunlight.
  • sapwood: Thick-walled cells that are responsible for transporting water and nutrients from the roots to the leaves. Also called new xylem.
  • snag: A standing dead tree from which the leaves and most of the branches have fallen.
  • softwoods: A coniferous or needle-leafed tree.
  • thinning: A common management practice in which smaller, weaker and defective trees are cut down so that the other ones can grow healthier and faster.
  • understory: The plant and tree community that lives on the forest floor.
  • xylem: The conducting cells in a tree that carry water and minerals to the trunk, branches, and leaves.
