Required for Observation in The Classroom: About a fortnight before this lesson is to be given, a box of soil should be prepared to receive the seeds. A few grains of wheat and a few beans should then be sown, and a few more of each every day up to the time when the specimens are required. By this means a series of specimens, illustrating all the earlier stages of growth, will be ready on the day for which the lesson is arranged.
If necessary, the growth of the seed, and the development of the young plants, may be hastened by keeping the box in a warm room.
Method of Student Observation:
- The specimens obtained as above directed are to be placed in order of their development, so that the children may observe the stages of growth in proper succession.
- The presence of much food material in the seeds may be proved by growing them in water; but elicit that the soil and the air become necessary sources of supply after the food stored up in the seeds is exhausted.
- The children may be encouraged to draw the young plants in their different stages from the actual specimens.
How to Grade Study Notes For Student Journals: Every student will need a journal to write in weekly for this online nature study series. Teacher will assign the weekly content in advance.
- Make sure the facts are: written in complete sentences, the first word of each sentence capitalized, and a period should be included at the end of each sentence.
- Spell check your vocabulary and write the words correctly.
- Dress up your journal entries with student clip art, drawings of your own in color or in black and white.
- Student may also include photographs of their own taking for extra credit.
- Growth of the Bean - At first the bean absorbs water from the moist soil, becoming much larger and softer. The skin then splits and the young rootlet protrudes. As the rootlet increases in length, the seed itself splits into two parts, thus revealing the young bud (plumule), which occupied a small cavity in the closed seed. The rootlet increases rapidly in length, giving rise to branched fibers and root-hairs, which absorb food from the soil for the growing plant. At the same time the young bud grows upward, seeking light and air.
The two halves of the seed remain attached to the young plant, forming a pair of thick, fleshy leaves (cotyledons). These contain a large store of plant food, by which the young plant is nourished until the root has sufficiently developed to absorb the necessary food from the soil. The function of the seed-leaves being over, they gradually shrivel, and finally drop off. - Growth of the Wheat - The grain of wheat passes through the same stages, except that the food store of the seed gives rise to one seed-leaf only, and does not split
like the bean.
