    Recently I was able to hear and then analyze an example on this topic.

    To begin with, it should be said that the essence of invisible threads is that in nature everything is interconnected, since everything living ultimately participates in the ecosystem.

    An example lies in the fact that in the USA, wolves were removed from a forest located in Ohio. As a result, over time, moose began to multiply too much.

    Moose are herbivores, so they completely began to eat all the trees.

    This even caused problems for the bears, as the rivers began to dry out faster, due to the fact that the trees did not block the scorching rays of the sun.

    In general, the entire ecosystem was out of balance and on the verge of self-destruction, until a couple of packs of wolves were again released into that forest, which over time normalized everything.

    As you know, in nature everything is interconnected. Threads can be found everywhere at any time of the year.

    Let's look at these connections using the example of a winter forest.

    Winter is coming, it gets cold, severe frosts can even strike, but the animals are saved by their warm fur.

    Also in winter there is less food for animals, but some animals are saved by hibernating and feeding on their reserves, some move closer to human habitation in order to profit there.

    Another example: snow falls in winter, everything turns white. Some animals, such as hares, change their color to make themselves less noticeable.

    Here's how you can show it clearly:

    In the winter forest there are a lot of food connections between animals and you just need to learn to see them.

    One of bright examples can be brought with pine trees. Cones grow on them, and they fall off as they ripen. In the spring, young tree shoots will emerge from them. But these cones also serve as food for birds and animals. And some small animals serve as food for predators. For example, a mouse will eat grains from a cone, and the mouse itself will be eaten by a fox. The tree itself, which serves as food for many, will not be able to grow without moisture (snow) and sun.

    Invisible are the threads or connections that exist in nature between all its components, both subjects of living nature and objects of dead nature. It is clear that greatest number Such connections can be found in the forest in summer or spring, but even in winter there are plenty of such invisible threads.

    First of all, let's remember about the snow, which covers everything in a deep layer winter months. Snow serves as a kind of blanket that protects the earth, plant roots and wintering insects from freezing - that’s one invisible thread. Further, the snow serves as a refuge for mice, other rodents and some birds, under which it is very difficult for predators to find them.

    In winter, the usual food chains between consumers of different orders and producers are preserved. hares gnaw the bark, deer and moose shovel the snow in search of grass, birds eat nuts and frozen berries, a fox hunts mice, and a wolf hunts a hare - that’s how many invisible threads appeared at once.

    A clear winter sky threatens severe frosts, because the last heat from the surface freely escapes into the atmosphere, and a cloudy, overcast sky promises not only snowfalls, but also a thaw.

Preparing the workplace for the lesson.

Updating knowledge

Let's remember......

In a certain kingdom, in a certain state they lived - they were......

No - no, not the king and queen.....

Each of these kingdoms is special. They are not far away, but very close to us, around us. These are the kingdoms of nature.

Let's take you on a journey through the kingdom of the living and inanimate nature.

What kingdoms of living nature do you know?

What are the main kingdoms of inanimate nature?

Student answers

Animals, plants, birds, bacteria, fungi.

Stones, sun, clouds, water.

Setting and solving an educational problem

Tell me, do connections exist in nature?

Let's repeat the connections in nature, let's call them invisible threads differently.

Invisible threads - connections in nature

Think about how a person can break these connections?

Today I invite you to visit a very beautiful time of year, and what time of year it is, you will find out from the riddle:

Snow on the fields

Ice on the rivers

The blizzard is walking.

When does this happen?

By what signs do we recognize the arrival of winter?

Let's remember the winter months.

Now we will see how winter affected the life of plants and animals. How do trees winter?

How do shrubs and grasses winter?

Why don't they freeze?

Here we see the connection between living and inanimate nature.

How do birds winter?

Winter is a difficult time in the life of animals, so humans

feeds them.

Guys, how can you help the birds get through this difficult time?

You are already helping the birds, feeders have been made, and food has been prepared for the birds.

Guess the riddles

Among the forest

Gray fur coat for summer,

A different color for winter.

Without wings

And faster than the birds

Flies from tree to tree.

Which bird hatches chicks in winter?

What kind of girl?

Not a seamstress, not a craftswoman.

She doesn’t sew anything herself,

And in needles all year round.

Guys, what do you think these animals have in common?

Various animals are related to each other.

Plants and animals are connected with each other, and humans are connected with them.

The connection between living and inanimate nature.

Man can destroy animals and destroy nature. Cut down the forest. Apply irreparable harm ecology.

Cold, air temperature below zero

The rivers were covered with ice and the ground with snow,

It's snowing often,

The day is short

I can't hear the birds

December January February.

Deciduous trees They have shed their leaves, and the conifers are green.

Shrubs are losing their leaves, grasses are turning yellow.

Snow protects from frost. The more snow, the easier it is for plants to withstand winter frosts.

The hare is a nocturnal resident. He spends the day in secluded places: under fallen trees, in bushes, under the paws of spruce trees. In severe frosts, it digs holes in the snow up to one and a half meters deep. It feeds on thin branches of aspen, willow, and birch. From thicker branches, it gnaws only the bark and eats dry grass.

The fox catches hares, but its main food is rodents, first of all. gray voles, which are slower than bank voles and mice. Fox hunting for rodents is called mouse hunting.

Foxes usually rest right on the snow, in open dens - somewhere in the middle of a field on a hill. The fox is safer here.

You can clearly see everything that is happening around.

The wolf is strong smart predator. Not only hares, but also large animals- wild boar, elk. Wolves usually hunt in small packs. They can persistently pursue their prey for a long time. True, in deep, loose snow they

it is difficult to run, and often the wolves remain hungry.

The most noticeable animal in the forest is the squirrel. In a forest where there are many hollow trees, a squirrel lives in a hollow. If they are not there, it builds a nest. The main food protein is seeds coniferous trees. The squirrel is still looking for the jay’s winter storage area under the snow, then unearths a cone dropped by a crossbill in the fall. In the hungry years of the squirrel

eats tree buds, especially spruce buds. Eats winter supplies: acorns, hazelnuts, mushrooms.

Birds that feed on insects flew away warmer climes. Magpies, tits, sparrows, nuthatch, woodpeckers, and crossbills remain for the winter. They continue to lead an active lifestyle. sparrows, magpies, crows feed near human habitations

ka. Woodpeckers and pikas feed on insect larvae, extracting them from under the bark of trees. Jays, goldfinches, and tits collect the remaining fruits and seeds of plants.

You can make a feeder, hang it on a tree, bring food there, hang a piece of lard at the window - for tits.

All of them are on the spruce tree or hiding under the paws of the spruce tree.

Animals hide among spruce branches and find food.

Work on the topic of the lesson

"Invisible threads in the winter forest"

Open the textbook page 36.

What do we call invisible threads?

Today we will look at this connection.

Spruce is one of the most interesting and beautiful trees in our forest.

Look at the drawing.

How is animal life connected to spruce?

But there is also a connection between animals - the “friends” of spruce. So, there is a peculiarity in the feeding of the crossbill: when it picks a spruce cone, it eats only part of the seeds from it, and then throws it away. Bro

Squirrels and woodpeckers pick up cones from crossbills in the snow, and this makes it easier for them to find food. But the cones dropped by the crossbill are even more important for wood mice and voles, who cannot pick them from the trees themselves.

This is how interesting the life of the winter forest is, so complex, although at first

A clear look and invisible connections in the winter forest.

Guys, what do you think, is there a connection between these animals?

Crossbill's diet includes next feature: when picking a spruce cone, he eats out only part of the seeds from it, and then throws the cone away.

Do you think any of the forest dwellers will pick up the cones thrown by the crossbill?

So, using the example of only one Christmas tree, we were convinced that it

connected by invisible threads with animals, because it serves them as shelter and provides them with food.

Now let’s complete the task in the workbook. Page 20th, exercise 1.

Open the textbook.

We called invisible threads the connections that exist everywhere in nature.

Inanimate and Live nature, plants and animals, various animals.

Animals feed on spruce seeds.

They hide among the spruce branches, under them.

Crossbills build nests on spruce trees in winter and feed their chicks with spruce seeds.

Squirrel - this will make it easier for her to find food.

Mice, voles - they cannot pick them themselves.

II. Updating knowledge

I invite you guys to the winter forest,

Where there are many fabulous miracles,

Where the blizzard covered the roads,

Where the clumsy bear sleeps in a den,

Where she lives in the ice palace

Beauty, sorceress - winter.

(Use your imagination. What could you see in the winter forest?)

How winter affected the life of plants and animals. How do trees winter?

Deciduous trees have lost their leaves, and coniferous trees stand green.

How do shrubs and grasses winter?

— Shrubs are losing their leaves, grasses are turning yellow, but not all of them.

What herbs go green under the snow?

— Strawberries, hoofed grass, and also go green under the snow.

winter wheat, rye.

- Why don’t they freeze?

Snow protects from frost. The more snow, the easier plants can withstand winter frosts

Now let's talk about the life of birds in winter.

— Children, do all the birds stay for the winter? Why?

— What are the names of birds that fly away to warmer regions in the fall?

- Why are they flying away?

What are the names of birds that stay for the winter? (Wintering)

- Name the wintering birds. (Tit, sparrow, woodpecker, pigeon, tit, bullfinch, magpie, crow)

— Birds that feed on insects have flown to warmer regions. Magpies, tits, sparrows, nuthatch, woodpeckers, and crossbills remain for the winter. They continue to lead an active lifestyle. sparrows, magpies, and crows feed near human habitations. Woodpeckers and pikas feed on insect larvae, extracting them from under the bark of trees. Jays, goldfinches, and tits collect the remaining fruits and seeds of plants .

— What birds come to us for the winter from the north?

— They flew to us for the winter from northern regions bullfinches and waxwings. Rowan berries are the best medicine for them.

The guys also prepared reports about wintering birds.

Crossbill lives in coniferous forests. The beak of crossbills is adapted to feeding on cone seeds, so the upper and lower halves of the beak are crossed. The male is brightly colored, while the female is grayish-green. These birds hatch their chicks in winter, because... It is in winter that there is a lot of food for them.

Tit - This is a dexterous, mobile bird. She does not fly away to warmer regions for the winter. It usually makes its nest in tree hollows. The bright yellow breast and belly of this bird are divided in half by a wide black stripe, on the head there is a black cap. In summer it feeds on bugs and worms, and in winter it eats everything: bread crumbs and boiled vegetables. But he especially loves unsalted lard.

Waxwings- They fly to us from the north and stay throughout the winter. Her wings are black with bright yellow stripes. There are red spots scattered at the ends of the feathers and on the head. A very elegant bird. They sing quietly and usually whistle gently. For this they were nicknamed waxwings.

Winter is a difficult time in the life of animals.

— Guys, how can you help the birds get through difficult times?

You can make a feeder, hang it on a tree, bring food there, hang a piece of lard at the window - for tits.

In the forest you can meet different animals and birds. But will we meet everyone in winter? Let's look at pictures and photographs and name those animals that you will not see in the winter forest.

/Children take turns and choose pictures/

Why don't we meet bears, badgers and hedgehogs in winter? (they hibernate for the winter)

We learn about how some animals spend the winter from the messages prepared by the guys.

And you can guess who the first message will be about by yourself by guessing the riddle.

a) Guess the riddle:

I walk around in a fluffy fur coat,

I live in a dense forest.

In a hollow on an old oak tree.

I'm nibbling nuts .

Squirrel. By winter, the squirrel insulates its nest, which serves as reliable protection during severe frosts and bad weather. The squirrel builds its nest in the forks of branches or in the hollows of trees. In frosts, when it is very cold, squirrels do not run through the forest, they hide in nests. A squirrel's nest is called gayno. A ball of branches high on the fir trees. It has one or two exits, and the inside walls are lined with moss. By winter, the squirrel makes food supplies. It’s funny to watch how a squirrel looks for nuts: it hits the branches of a hazel tree with its paw and sees which one swings the most. So there are nuts on this branch. He selects the best fruits for food and reserves. The squirrel dries mushrooms itself in summer and autumn. If you bite into a fungus, is it tasty? Then prick it on a twig and let it dry until winter. It happens that hundreds and even thousands of fungi dry out over the summer.

b) The owner of the forest

Wakes up in the spring

And in winter, under the blizzard howl

Sleeping in a snowy hut .

Bear. Before lying down in the den, the bear confuses its tracks like a hare, meanders through the windfall and water, jumps sideways from the trail, in a word, it will walk back and forth more than once. A den is a hole dug somewhere under the roots of a tree, lined with grass and dry fern even before the first snow. The bear lies down with his head to the hole, covers his muzzle with his paw and sleeps. At this time, he does not eat food, but lives off accumulated fat. They say that in winter bears suck their paws in their dens. In fact, the old rough skin comes off the bear’s feet, and the young, tender skin needs to be warmed. That's why the bear licks the soles with a hot tongue, smacking his lips at the same time. So it seems that he is sucking his paw. If you wake up the bear, he leaves the den hungry and at this time can be very dangerous. It is called a bear - connecting rod.

The horns are heavy in weight,

He walks importantly through the forest:

He is the host, not the guest -

Gloomy and angry...

- Elk- forest giant. All of it reaches up to 400 kg. Such an animal needs a lot of food. The elk slowly wanders among the bushes and young trees, eating their branches. If it encounters a fallen aspen, it gnaws the bark. All this food is low in nutrition. Scientists have calculated that a moose can eat more than 1,700 twigs in a day! From time to time, the elk rests, burying itself in loose snow. And then back to food.

c) Behind the trees, bushes

The flame flashed quickly.

It flashed and ran.

There is no smoke, no fire.

Fox. The fox hunts at dusk or at night for birds, hares, and hedgehogs. Sneaks up on prey unnoticed, suddenly rushes at it and grabs it sharp teeth. Like a cat, he loves to play with his prey. In winter you can see a fox sniffing the snow. In fact, she tracks mice by smell under the snow, quickly digs the snow with her front paws and grabs the prey. By destroying mice, the fox brings benefits. During severe snowstorms and bad weather, she seeks shelter, curls up in a ball and covers herself with her tail.

Gray, toothy,

Prowls across the field,

Looking for calves and lambs.

Wolf– a strong, intelligent predator. Not only hares, but also large animals - wild boar, elk - become his prey. Wolves usually hunt in small packs. They can persistently pursue their prey for a long time. True, in deep, loose snow they

it is difficult to run, and often the wolves remain hungry.

d) The scythe has no den,

He doesn't need a hole.

Legs save you from enemies,

And from hunger - bark .

Hare. Hares have hind legs that are stronger than their front legs. He runs through the loose snow on his furry paws easily, like on Canadian skis. He sleeps lightly, dozes half asleep with with open eyes, closing them only for a minute. During heavy blizzards and snowfalls, the hare hides in shallow holes, in bushes, and lies down in the hole from a jump, so there are no traces nearby

Physical education lesson “Hares”

Where did the bunny hide?

Guess the riddle

What kind of girl?

Not a seamstress, not a craftswoman.

She doesn’t sew anything herself,

And in needles all year round.

(Spruce)

Who else will we meet at the Christmas tree?

Without wings

And faster than the birds

Flies from tree to tree.

(Squirrel)

Which bird hatches chicks in winter?

(Crossbill)

Among the forest

(Woodpeckers)

— Is there a connection between these animals?

All of them are on the spruce tree or hiding under the paws of the spruce tree.

Animals hide among spruce branches and find food.

Communicating the topic and purpose of the lesson

- Today we will look at this connection. What will we call the topic of our lesson?

"Invisible threads in the winter forest"

—What do we call invisible threads?

We called invisible threads the connections that exist everywhere in nature.

Inanimate and living nature, plants and animals, various animals are interconnected.

Statement of the problem and discovery of something new.

Spruce is one of the most interesting and beautiful trees in our forest.

- Who is spruce friends with? Let's open the textbooks on p. 36 - Imagine that we go out into a clearing, in the middle of which a beautiful spruce tree grows.

Let's read a story in the textbook called “Who is the spruce tree friends with?”

/A good reading student reads a story./

- Look at the diagram.

How is animal life connected to spruce?

Animals feed on spruce seeds.

- They hide among the spruce branches, under them.

— Crossbills build nests on spruce trees in winter and feed their chicks with spruce seeds.

- But there is also a connection between animals - the “friends” of spruce.

How do animals help each other? Let's read the story in the textbook on p. 38/A good reading student reads the story./

So, there is a peculiarity in the feeding of the crossbill: when it picks a spruce cone, it eats only part of the seeds from it, and then throws it away. Cones thrown by crossbills are picked up in the snow by squirrels and woodpeckers, and this makes it easier for them to find food. But the cones dropped by the crossbill are even more important for wood mice and voles, who cannot pick them from the trees themselves. This is how interesting the life of the winter forest is, how complex, although at first glance invisible, the connections in the winter forest are.

Using the example of just one Christmas tree, we were convinced that it serves both as a shelter for animals and provides them with food.

Think about it, why can you call them friends of spruce?

- They are connected by a food chain and spread seeds.)

Do you think that if the spruce tree did not have such friends, would the seeds be able to get into the ground?

It turns out that spruce cones open on their own as soon as the February or March sun begins to warm them, and light winged seeds spill out of them, which are picked up by the wind and carried in different directions.

So, using the example of only one Christmas tree, we were convinced that it is connected with invisible threads with animals, because... it serves them as shelter and provides them with food.

Consolidation of what has been learned.

      Who sleeps in the snow under the fluffy branches of spruce?

      Which bird has a beak adapted for removing seeds from cones?

Physical education for the eyes “Herringbone”

What happens if…

Cut down all the spruces.

Just recently there was a holiday - New Year. On this holiday, it is customary to bring a spruce into the house. Now imagine that someone would cut down our Christmas tree for their own holiday. What would happen? /The teacher removes the image of a spruce from the board/ (Animals would be left without a home, food, shelter.)

But what should we do? (You need to put up an artificial spruce or decorate a tree in nature.) Take care of your spruce!

By cutting down spruce trees, we deprive animals of home, shelter, and food.

Summing up the lesson

So our lesson has come to an end. What new have you learned?

What do we call invisible threads?

Do they exist in the winter forest?

Did you enjoy our “walk” today? Anyone who likes it can “plant” their own little Christmas tree by attaching it to the board. (The guys have on their desks paper Christmas trees, and those who wish can come up to the board and attach their Christmas tree to it.)
