Lesson CCVII
The Witch-Hazel
Leading thought—The witch-hazel blossoms during the autumn, and thus adds beauty to the landscape. It has an interesting mechanism by which it can shoot its seeds for a distance of many feet.
Method—This lesson divides naturally into two parts; a study of the way the seeds are distributed is fitted for the primary grades, and a study of the flower for more advanced grades. For the primary grades the lesson should begin by the gathering of the twigs which bear the fruit. These should be brought to the schoolroom—there to await results. Soon the seeds will be popping all over the schoolroom, and then the question as to how this is done, and why, may be made the topic of the lesson. For the study of the flower and the shrub itself, the work should begin in October when the blossoms are still in bud. As they expand they may be studied, a lens being necessary for observing the interesting little doors to the anthers.
Observations—1. Is the witch-hazel a shrub or a tree?
2. What is the color of the bark? Is it thick or thin, rough or smooth, dark or light, or marked with dots or lines? Is there any difference in color between the older wood and the young twigs? Is the wood tough or brittle? Dark or light in color?
3. Do the leaves grow opposite each other or alternate? On what part of the plant do the leaf buds grow?
4. What is the general shape of the leaf? Is it more pointed at the base or at the tip? Are the leaves regular in form, or larger on one side than the other? Are the edges entire, toothed or wavy? Are the petioles short or long? Are the veins straight or branching? Are they prominent? Are the leaves of the same color on both sides?
5. Are there many queer-shaped little swellings on the leaf above and below? See how many of these you can find? Tell what you think they are.
6. Do the flowers grow singly or in clusters? What is the shape and color of the petals, and how many of them are there in each blossom? Describe the calyx. If there are any flower buds just opening, observe and describe the way the petals are folded within them.
7. How many stamens? With a lens observe the way the two little doors to the anther fly open; how is the pollen thrown out? What is the shape of the pistil? How many stigmas?
8. Does each individual flower have a stem or is there a common stem for a cluster of blossoms? Do the flowers grow at the tips or along the sides of the twigs? When do the witch-hazel flowers appear and how long do they last?
9. Make a drawing of a witch-hazel nut before it opens. What is the color of the outer husk when ripe? Cut into a closed nut and observe the extreme hardness and strength of the inner shell.
10. Where are the seeds situated? Can you see that the shell, when partially open, ready to throw out the seeds resembles a queer little face? Describe the color and marking of the seeds; are they rough or smooth? How far have you known the witch-hazel to throw its seeds? Study the nut and try to discover how it throws the seeds so far.
