Free Nature Studies: Seed Homes & Anatomy“Seed Homes”

This week we’ll cover seed anatomy; and next week how seeds travel.

Suggestions
  • Review pollination.
  • Add a page in your notebook for each of the plants mentioned: white bean (haricot), tomato, potato, spruce tree, pecan tree, filbert, chestnut, and Brazil nut.
  • Observe a bean plant growing and note the various stages mentioned in the lesson (or if you are in a hurry, watch the time lapse video below).
  • Plant and observe a tomato plant growing. Note the various stages mentioned in the lesson (or if you are in a hurry, watch the time lapse video below).
  • Cut and cross-section a green tomato and a ripe, red tomato. Notice the difference in their seeds.
  • Plant and observe a corn plant growing. Note the various stages mentioned in the lesson (or if you are in a hurry, watch the time lapse video below).
  • Plant a potato from an “eye.”
  • Can you find the twin seed “cradles” of the maple tree?
  • Examine the elm tree “cradle.”
  • Compare and contrast the maple tree and elm tree cradles.
  • View the brown cradles of the oak (acorns).
  • Examine an apple cross-section.
  • Read a little about the Brazil nut and see its odd seed cradle arrangement.
  • Make a list of the different seed homes discussed. What others can you add?
  • Something to do #1: When arranging your seed collection, read Seed Art for inspiration!
  • Something to do #2: The author gave a hint as to the reason nuts have hard shells near the bottom of pg. 201. Can you guess?
  • Something to do #3: Read about the strawberry, red raspberry and currant.
  • Something to do #4: If you don’t have a pin cherry seed available, you can read a description at the Minnesota Department of Natural Resources.
  • Something to do #5: Rather than describe your life as a chestnut, a simple narration can be substituted after reading a field guide on American chestnut trees.
  • Something to do #6: This article on how to grow roses from seed will help you describe a rose seed home.
  • Memorize and recite Matthew 13:31, 32.
  • Use Genesis 8:22 for copywork or dictation.
  • More about seed homes and nuts from the Book of Knowledge:

    A seed consists of an embryo plant, a food supply to keep this little plant alive until it starts making its own food, and a protective covering…. [T]he embryo plant results from the processes of pollination and fertilization that took place in the flower. Seeds develop inside fruits.

    There are fruits that contain just one seed, such as the olive, cherry, peach and avocado. Most nuts, acorns, and the various grains such as wheat, corn, oats, rice and rye are one-seeded fruits that we refer to as seeds because the “fruit” part is only a tight skin or shell around the seed, and fruit and seed could hardly be distinguished.

    When the fruit of a tree or a shrub is inclosed in a bony, woody or leathery covering that does not open when ripe, it is commonly called a nut. Some people, indeed, live almost entirely on nuts.

    Nuts differ very much in their formation, and fruits like the walnut and chestnut, which have a thick outer covering that has to be removed before what we call the nutshell is exposed, are really at a stage between a stone fruit, like the plum, and a nut that has its shell exposed, like the filbert.

  • Plants
    Ready to go outdoors? The Handbook of Nature Study covers plants beginning on page 453, and continuing through page 731. The beginning pages cover how to begin the study of plants and their flowers, and then follow guidelines for investigating specific wildflowers, weeds, garden flowers, cultivated crop plants, trees, and flowerless plants.

Books

A Seed is SleepyA Seed is Sleepy by Dianna Hutts Aston
This beautiful picture book is a wonderful addition for the young seed explorer.  Simple text, but still uses scientific terms.  The illustrations alone will captivate.

The World of PlantsThe World of Plants by Dinah Zike
Dinah Zike was known for her foldables before lapbooks became popular. In this book she incorporates that learning tool with learning about plants. Includes 24 complete lessons including templates, activities, the scientific method and suggestions for further activities and research. You’ll find the table of contents and an example lesson at the publisher’s website. A lessons on conifers and seeds are included.
