Book summary “Handbook of nature-study for teachers and parents”: summary

Introduction

You face the constant challenge of connecting children with the natural world through accurate observation rather than dry, formal science. Children often lose their innate curiosity when adults force them to memorize rigid taxonomic classifications instead of encouraging direct contact with living things.

Nature-study consists of simple, truthful observations of common plants, animals, and physical phenomena threaded upon understanding to build logical knowledge and a love for the out-of-doors.

Anna Botsford Comstock offers a comprehensive guide covering vertebrates, invertebrates, plants, trees, earth, and sky to solve this educational dilemma. You will discover how to transform ordinary schoolyards and living rooms into laboratories of living wonder.

• How do you teach children to see common animals and plants without destroying their natural curiosity?
• What specific methods help you study birds, insects, and trees without heavy textbooks?
• How do you answer difficult questions about nature when you do not know the answers yourself?

1. The Teaching of Nature-Study

Nature-study consists of simple, truthful observations threaded upon the understanding to build logical knowledge and a love for the out-of-doors.

The primary object is to cultivate accurate observation and comprehension rather than merely imparting practical knowledge. It differs from elementary science because it begins with the specific plant or creature nearest at hand rather than following a logical taxonomic progression. Ornithology as a science might start with the Archaeopteryx and progress to scratching birds and song birds, whereas nature-study begins with the robin because you see it in March.

Teachers should freely admit when they do not know the answer to a nature question, turning it into a shared investigation with the pupils.

Pretending to know everything destroys pupil trust because children have keen eyes for detail. The author spent three years walking afield with two little children who frequently kept her saying "I do not know," yet they never lost confidence in her knowledge.

You can apply these steps in the field:

• Say frankly: "I do not know; let us see if we cannot together find out this mysterious thing."
• Convey the impression that only a little about the intricate life of plants and animals is yet known.
• Make pupils feel the thrill and zest of investigation.

Uninterested pupils should be kept at regular school work and excluded from the nature-study class rather than forced to study unappealing subjects. Lessons should last between ten minutes and a half hour without dawdling. Repeating a lesson creates disgust in students unless it is recalled for comparison with a related species, such as comparing a violet to a pansy. A disgusted boy complained: "Darn germination! I had it in the primary and last year and now I am having it again."

Schoolrooms should be equipped with live specimens housed in terraria, breeding cages, aquaria, and observation hives to foster continuous study. In a second-grade classroom, pupils were allowed five-minute visits to aquaria and terraria as a reward of merit, which successfully solved the problem of discipline.

You need to provide specific equipment:

• Provide terraria and breeding cages for insects, toads, and little mammals.
• Set up aquaria for fishes, tadpoles, and water insects.
• Establish a window garden as a basis for plant growth study.

A simple hand lens costing a dollar, or even fifty cents or twenty-five cents for a fairly good lens, is indispensable for revealing minute natural wonders. You can chain an excellent lens to a table, desk, or pocket so it can be used at recess.

You should fix the attention of the pupil on the real object first before using any diagram or chart. Scientific names for anatomical parts and popular names for species should be used naturally so children learn them without rote memorization.

Field note-books provide a personal record of out-of-door experiences and serve as a gold mine for teachers to understand children's interests. A lad of fourteen kept a quarto note-book adorned with marginal illustrations inspired by Thompson-Seton and text influenced by Thoreau.

You must follow these practices for note-books:

• Consider the book the personal property of the child and do not criticize it except for encouragement.
• Encourage the making of drawings to illustrate observations.
• Exempt spelling, language, and writing from criticism.
• Place observation outlines in the note-book before field excursions.
• Never compel any child to have a note-book.

Organizing Junior Naturalists Clubs and conducting meetings under parliamentary rules provides invaluable training in public speaking and language expression. Under John W. Spencer, Junior Naturalist Club members conducted formal meetings with extreme dignity, and students eagerly wrote letters to "Uncle John" that teachers were requested not to correct.

2. Birds and Their Adaptations

Identifying a bird is only the alphabet of bird study, serving merely as a tool to uncover the animal's life habits.

True ornithologists and beginners alike should aim to understand the daily habits and ecology of the species rather than treat identification as a final goal. A bird's overlapping feathers act like shingles on a roof to keep the underclothing dry during rain. A hen in the rain droops her tail and holds herself so water finds no resting place but flows down her steep surface to the ground.

You can observe these details through direct inspections:

• Observe how feathers are arranged on the back of the hen like shingles on a roof.
• Observe how a hen looks and behaves when standing in the rain.
• Compare a feather from the back and one from the breast and note the difference.
• Check the fluffy part and the smooth web part relative to the bird's skin.
• Examine a pin-feather and cut the sheath open to see the young feather lying within.

Male birds develop bright ornamental plumage through sexual selection to win mates, while mother birds retain modest colors for protective camouflage. The mother partridge matches dead leaves so closely she can almost be stepped on, whereas the male Baltimore oriole displays a gleaming orange coat and distracts predators by song.

You can study these ornamental contrasts further:

• Compare the plumage of the hen and the rooster.
• Study the turkey gobbler and a peacock in life or in pictures.
• Compare the plumage of a Rouen duck and drake.
• Examine the plumage of the Baltimore oriole, the goldfinch, the scarlet tanager, and the cardinal.

Birds fly by pressing down upon the air with curved, overlapping wing feathers, using their tails as rudders. A teacher in Elmira, N. Y., introduced a hatching hen into the schoolhouse basement, and children use fans and open umbrellas to test air pressure. Because birds use their arms for flying, their beaks and feet have evolved to act as their primary hands, tools, and weapons.

You should also examine how physical structures support survival:

• Compare the beak of the hen or chick with that of the duckling or gosling.
• Observe the shape, hardness, and saw teeth along the edge of the duck's bill.
• Examine the nostrils situated near the base of the bill in both fowls.

3. Fish, Amphibians, and Reptiles

Aquatic vertebrates and creeping animals display remarkable physical adaptations for locomotion, respiration, and defense in water and land habitats.

Goldfish in Chinese streams originally wore safe green colors like brook shiners, and escaped goldfish in rivers revert to this olive-green hue. Their bodies feature seven distinct fins that serve precise hydrodynamic functions: pushing, steering, and stabilizing through the water. Miss Ada Georgia kept goldfish in a school aquarium until they were seven years old, while the record lifespan of a goldfish is nine years.

The bullhead possesses sensory barbels around its mouth to test its muddy environment. It lacks scales, relying on a thick, leathery skin and sharp pectoral spines for defense. Both parents actively construct nests and meticulously agitate and guard the fry after hatching.

Toads undergo a two-phase life cycle starting as aquatic, gill-breathing tadpoles and transforming into air-breathing land animals. Mother toads lay long strings of jelly-like transparent eggs in ponds in May and June. Hatched tadpoles initially breathe with external tassels of gills which later shift inside the throat, use a flat tail for swimming, develop hind legs first followed by front arms through the breathing-pore, and eventually absorb their tails and walk onto land.

You can study tadpoles by following these steps:

• Go to a pond where tadpoles live.
• Place small stones from the pond bottom in a pan, building one side higher so water is shallow.
• Add mud, leaves, and underwater plants from the pond.
• Fill the pan nearly to the brim with pond water without disarranging plants.
• Add no more than a dozen tadpoles after the mud settles.
• Add a little more mud or a slime-covered stone every week, and replenish evaporated water.
• Keep the aquarium out of direct sunlight.
• Feed tadpoles the exposed pulp of a tulip leaf and occasional bits of hard-boiled egg.

4. Mammals and Domestic Animals

Mammals are united by nursing their young with milk while exhibiting diverse specializations in teeth, locomotion, hibernation, and domestication. Recognizing this defining characteristic helps you understand that diverse forms such as whales, cows, bats, and humans share a biological kinship.

A cotton-tail rabbit survives through strong hind legs for swift leaping, long ears for early warning, and a protective coat suited for freezing in place.

It uses its front feet like a vaulting pole, landing its hairy hind feet ahead of them. Its split upper lip aids constant nostril wabbles for scent detection, and its gnawing incisors help it feed on bark and herbs in winter. A cotton-tail once led a dog to the verge of a precipice and doubled back to safety, causing the dog to fall three hundred feet below. Young rabbits run quite rapidly when they reach three weeks old, taking jumps of eight feet or more.

You can study rabbits by following these steps:

• Examine tracks in the snow to determine direction, time of activity, and foot protection.
• Observe the size, movement, and attitudes of the ears during rest, alarm, or running.
• Note the movements of the nostrils and the split upper lip in scent detection.
• Inspect the teeth, whiskers, eyes, and the relative sizes of front and hind legs and feet.
• Record observations on toilet habits, summer and winter food, nest construction, and enemies.

5. Insects and Social Colonies

Insects undergo complete or incomplete metamorphosis, utilize spiracles for breathing, and form complex social societies with specialized castes.

Insects with complete metamorphosis go through four distinct developmental stages. The larval stage is exclusively devoted to eating, growing, and periodic skin shedding called molting because the outer chitinous skeleton cannot stretch. The pupa stage is a period of transformation, which results in an adult insect that possesses six legs, wings, and complex structures but never grows larger or molts. An insect breathes not through its mouth, but via lateral body openings called spiracles connected to an internal network of air tubes.

You can study aquatic insect life by setting up a simple school aquarium:

• Place a layer of sand an inch or more deep in a glass jar.
• Plant water-weed, bladderwort, water starwort, watercress, stoneworts, frog-spittle, or water-silk in the sand.
• Add a top layer of small stones or gravel to hold plants in place.
• Tip the jar slightly and pour in pond or stream water gently to within two or three inches of the top.
• Let the water settle.
• Place the jar in a north window or far enough to the side of another window to avoid direct sunlight.

Dragon-fly nymphs operate as ferocious aquatic predators using a highly modified, extendable lower lip as a trapping mask.

You can collect and observe dragon-fly nymphs by following these steps:

• Collect nymphs in April and May from reedy pond bottoms or slow stream edges using a dip-net.
• Keep each nymph isolated in its own container due to their voracious cannibalistic nature.
• Provide sand, water weeds, and a protruding object for the emerging adult.
• Feed them water insects or tied pieces of fresh meat removed after a few hours.

Mosquito larvae and pupae must regularly pierce the water surface film with breathing tubes to obtain air, making them vulnerable to oil applications.

You can protect your surroundings from mosquitoes using these methods:

• Rain barrels should be securely covered.
• All stagnant pools should be drained and filled up if possible.
• Cover the surface of breeding ponds or pools with a spray of kerosene oil using a spray pump or watering can.
• Introduce minnows, sticklebacks, sunfish, and goldfish into pools that cannot be drained or oiled.

6. Invertebrates, Wildflowers, and Cultivated Plants

Invertebrates like earthworms and spiders shape soil and spin webs, while flowering plants rely on insect partnerships and specialized structures for pollination and seed dispersal.

Charles Darwin calculated that garden soil in England contains more than 50,000 earthworms per acre, passing 18 tons of vegetable mold through their bodies yearly. You can observe these soil builders by trying these practical steps:

• Remove casts from a square yard of earth one day and examine the area the next day to estimate nighttime work.
• Set up a schoolroom terrarium with soil and scattered dead leaves to observe earthworm burrowing and feeding habits.
• Place an individual worm with earth on a desk to study its crawling movements and setae.

Young spiders disperse across long distances by releasing silk threads that act as balloons, using air currents to carry them far away. You can explore spider behavior and web architecture using these methods:

• Observe a cobweb in the corner of a room with a spider in it.
• Imprison a spider under a tumbler or in a vial to examine its legs, body sections, fangs, palpi, and eyes.
• Find an orb-web with a spider in attendance, break the web without frightening it, and watch it replace the web in the early evening or at daybreak.
• Look across grass on a warm sunny morning or evening in early fall to observe gleaming single threads spun from grass stalk to grass stalk.
• Find a small spider on a bush or fence post and watch it begin to spin out its thread.
• Ask children to bring a crab-spider to school in the flower where it was found to examine its protective coloration.
• Bring in spider egg-sacs in September and October, keeping some unopened and opening others to count eggs and emerging spiderlings.

Flowers lack legs or wings to transport pollen, so they reward visiting insects with nectar and pollen in exchange for carrying out cross-pollination. You can study these plant partnerships and seed germination through these exercises:

• Find a plant like pine and observe the wind sifting its pollen over young cones.
• Catch a bee in a glass fruit jar from a clover head to inspect the pollen dust on its body and the pollen packed in the baskets on its hind legs.
• Observe how flowers signal insects using color or fragrance, noting how dandelions and clovers close or hide colors on dark, rainy days.
• Observe whether the root or the leaf comes out of the seed first during germination.
• Check which way the root always grows, regardless of which side up the seed is planted.
• Check which way the leaves always grow, regardless of planting orientation.
• Examine how seed-leaves get out of the seed-coat and how they differ in form from later leaves.

7. Trees, Fungi, Earth, and Sky

Trees function as starch factories, fungi recycle organic matter, and physical geography and astronomy govern weather patterns and celestial movements.

You can study trees as living starch factories. Roots absorb water and dissolved nutrients while anchoring the tree. A mature maple of vigorous growth exposes nearly a half acre of leaf surface to the sun. Leaves use sunlight to power photosynthesis, converting raw materials into starch.

Fungi lack green chlorophyl and survive as parasites or saprophytes by obtaining organic food from living hosts or decaying material. Saprophytic fungi break down dead wood and organic matter, returning gases to the air and producing humus, thereby preventing forests from choking on debris. Bracket fungi enter living trees through open wounds, causing internal wood decay and ultimately sealing the tree's doom.

You can observe geological forces by examining local water and mineral systems. Brooks act as vigorous geological workers that erode banks, transport sediment during floods, and systematically sort and drop their load from heaviest to lightest. When mineral or chemical solutions evaporate, particles assemble into solid forms with plane surfaces set at exact angles.

Weather systems operate through atmospheric circulation and pressure changes. By filling a closed glass tube with mercury, sealing the open end with a finger, inverting it into a cup of mercury without letting air in, and measuring the remaining column height, atmospheric pressure is determined. You can read weather maps using continuous lines called isobars for equal atmospheric pressure and dotted lines called isotherms for equal temperature.

Star study provides permanent reference points in the night sky. The Big Dipper's pointers serve as the primary navigational tool to locate the North Star, which remains fixed above the North Pole. Orion dominates the southern winter sky with its prominent belt, sword, and bright bounding stars Betelgeuse and Rigel.

You can apply these methods directly in field and classroom activities:

• Collect all ferns of the locality while studying their fruiting forms.
• Make a fern herbarium by pressing and mounting ferns on white paper.
• Create leaf-prints or pencil and water-color drawings with enlarged details of fruiting organs.
• Lay a fern in fruit on a sheet of white paper and leave it undisturbed for a day or two to observe the spore dust outline.
• Take a fertile plant with discs surrounded by green ridges, shake it over white paper, and observe the released spores.
• Bring dried moss into the classroom, drop it into a glass of water, and watch the automatic leaf movement and expansion.
• Avoid all mushrooms covered with scales or possessing a stem base enclosed in a sac.
• Avoid young button stages, species with milky juices unless reddish, and specimens with brightly colored caps or decaying meat.
• Collect globular fungi in early white stages along with their growing substrate, observe their internal meat color, and test mature smoke release on white paper.
• Paint or cover bruised tree wounds with a coat of tar immediately.
• Saw off hanging splinters left by broken branches, leaving a smooth stump, and paint it.
