Introduction

Welcome to the forests of Ohio.  Look around and get comfortable.  You will be here for a while.  You are part of a team of four newly hired botanists for the Ohio Department of Natural Resources.  People have a lot of questions about leaves and the trees they come from.   Will you have the answers they seek?  Will you be able to deal with their questions with knowledge and expertise?

Task
Your job is to produce a set of fact cards. Visitors walking in the state forests of Ohio will be able to use these cards to identify the most common deciduous trees of Ohio by their leaves.

The leaf characteristics fact cards must include drawings of important characteristics in the identification of leaves.

The tree identification fact cards must include the name of the tree, type, shape, arrangement and margins of the most common leaves in Ohio.

Process

The class will be divided into groups of 4. Get your group assignment from
        your teacher.

Decide which of the following roles each member of your group will assume.

  • The leaf shape specialist: This person is responsible for finding the most common shapes of leaves. All common shapes should be drawn and labeled on a 5 X 8 notecard. You should be able to find at least 11 common shapes.
  • The leaf margin/edges specialist: This person is responsible for finding the most common shapes of the teeth of the leaves. All common margins should be drawn and labeled on a 5 X 8 notecard. You should be able to find at least 9 common edges of leaves.
  • The leaf arrangement/position specialist: This person is responsible for finding the most common arrangements of the leaves on the twigs of the tree. All common arrangements should be drawn and labeled on a 5 X8 notecard. You should be able to find at least 3 common leaf positions.
  • The leaf type specialist: This person is responsible for finding the most common ways that the leaves grow from the stem. All common types should be drawn and labeled on a 5 X 8 notecard. You should be able to find at least 3 common types.
    • Specialists, you must now locate the required information for your leaf characteristics notecard as listed behind your role. The following sites should contain a lot of the information that is necessary for the completion of this task. You may also use leaf identification books to locate the information. On each card, the source of your facts must be listed.

    When each specialist has completed their leaf characteristic card, one member of the group should see the teacher for a stack of 3X5 notecards and 2 lists of trees your group will be responsible for.  Each group will have a total of 10 trees.
    On the front of each tree identification card write the name of one of the trees from the two lists below that you are assigned.  You have a total of 10 trees that belong to your group.

    Conclusion

    Your team of botanists should know a wealth of information about Indiana's deciduous trees and their leaves. You should be able to help visitors as they ask you to identify leaves. Explain the leaf shapes, margins, arrangements and types using your leaf characteristics cards, then help people identify the trees with the tree identification cards. Teach visitors how to use your cards for their own leaf collections. Visit the forests often.
