IV . Updating knowledge.

Today we will continue to comprehend the secrets of the surrounding world in the spring, and a riddle about one of the spring months will help you determine the topic of our lesson.

The forest, fields and mountains wake up,
All the meadows and gardens.
He knocks on every hole,
Humming by the water.
"Wake up! Wake up!
Sing, laugh, smile!”
A pipe can be heard far away.
It wakes everyone up (April)

Why did April receive such names as “primrose” and “bloom”?
(IN this month the first greenery appears, some plants awaken and bloom)

Formulate the topic of the lesson.

Spring awakening of plants.

What would you like to learn in today's lesson?

Goal: Get to know the primroses.

TASKS

To know:

What types of primroses are there?

Where do they grow?
Why do they bloom first?

Learning new material.

The snow barely has time to melt when the first bright colors of spring light up in the thawed patches. White, golden yellow, pink, purple, lilac flowers are the first to welcome spring. They appear and bloom early - in April-May, even when the snow has not completely melted.

For this they are called snowdrops or primroses.

Open the textbook on page 74 and find out by reading the first paragraph what other names such plants are called. (Early flowering)

Which plants include such “daredevils”? (Among trees, bushes and grasses).

Let's get acquainted with early flowering herbaceous plants.(Mother and stepmother, corydalis, anemone, lungwort, liverwort, goose onion, guillemot)

How many of you have ever seen these plants in nature? (Of course, because all these primroses grow on the territory of our Republic of Bashkortostan.)

Read paragraphs 2 and 3 of the text and prepare to answer the questions: Where do early flowering plants grow and what do they need for early flowering?

Students read the text and look for the answer to the question.

Where can you see early flowering plants? (In the forest and in open areas)

Do these plants require a lot of heat? ( No)

(That’s why they bloom when not all the snow has melted yet.)

- What conditions do they need for early flowering?

Where do these plants get their nutrition to bloom?

(These plants receive food from their own storerooms. These are thickened underground parts of plants. Reserves accumulated in them last year and were stored all winter.)

What are the underground parts of plants? (Roots)

Look at the roots of primroses on pages 74 and 75 and notice how thick they are; nutrients have accumulated in them since last year and are ready to give them to the plants.

Group work

Now you will work in groups.

Listen carefully to the task. Each group will study their primrose according to the plan.

Read the first paragraph of the plan. (Image.)

Here you will paste the picture by completing the puzzles.

Name the second point of the plan. (Name.) You will find the name of your plant on the board and write it in the table.

To complete tasks 3 and 4, you will need to turn to additional sources.

(Electronic supplements to textbooks, anthologies).

Protection of mini-projects.

Coltsfoot.

Corydalis.

Lungwort

liverwort

Goose onion

Anemone.

And the last primrose is the clear one. It is often confused with anemone. Lyudmila Solonitsina will tell us about him. She prepared her message about this plant in advance.

Chistyak blooms in the forest at the same time as anemone. He has the same small stature and yellow flowers. At first glance, these two plants can be confused. But if you look closely, you can find differences. Anemone flowers usually have 5 petals, while the anemone has more petals - from 6 to 14 pieces. The leaves of the anemone are rugged and thin, while the leaves of the anemone are round and shiny. And the whole bunch looks so strong: cheerful, clean and fresh. And it got its name because has long been used as a so-called blood-purifying spring salad.

Primroses are beautiful and varied.They bloom from April to mid-May. Many people go out into nature to admire spring plants. And some people collect bouquets from them. Is it good?

All these plants rare and listed in the Red Book of Bashkortostan.

Do not pick primroses and do not buy them from violators of environmental laws! Every resident is obliged to preserve the unique flora of our republic!

Study of spring flowering of trees and shrubs

- Early flowering plants are found among trees and shrubs.
- Open page 76. Let's read and find out information about them.

- Which trees and shrubs begin to bloom before their leaves appear? (Alder, willow, hazel, wolf's bast)

Divide them into groups of shrubs and trees.

Which tree blooms first? (Alder)

Student reports about trees and shrubs.

Alder- a short tree with a thin and often crooked trunk. The trunk is gray, smooth, the leaves are oval, medium in size. Alder leaves are similar in shape and size to apple tree leaves, the same oval, with a sharp end. IN winter time the alder has clearly visible brown catkins hanging down. They are quite short and dense. In the spring, during flowering, the catkin elongates greatly, and abundant yellow pollen spills out of it. Alder releases pollen very early in the spring, earlier than all other trees.

Which tree blooms next? ( ANDva)

Willow grows along the banks of forest rivers, along streams, ditches when the forest has not yet become green ( early spring). Willow blooms with yellow downy feathers. A special genus of willow is called pussy willow. A beautiful willow with fluffy, fur-like earrings. It blooms when there is still unmelted snow in the forests. Flowering willow is a sure sign of the arrival of spring.)

Guys, where does willow grow? ? ( Along the banks of rivers).
Hazel - This is a bush. It grows in forests. Its leaves are large, wide, irregularly oval, with numerous teeth along the edge. The hazel tree blooms in early spring, unfurling its lush yellow catkins. And if the wind blows, they sway in different directions and scatter their pollen, which resembles a fine yellow powder.

Wolf's Bast- this is a bush. It blooms in the forest after the snow melts. Pink flowers similar to lilac flowers appear on thin twigs. They sit in dense groups, as if glued. Delicate flowers have a pleasant pungent aroma. Leaves on the branches appear towards the end of flowering. They are small and elongated. And by mid-summer, bright red fruits appear. But they are poisonous. That's why it was called "wolf's bast". Why bast? After all, this is the name of the linden bark from which bast shoes were woven. And the bark of our little plant is as strong as bast. This shrub has become rare and needs protection.

Let's return to the text of the textbook. Find the answer to the question.

Why are these trees and shrubs the first to bloom after winter dormancy?(They are the very first to begin the movement of sap. The sap rises along the trunks and branches to the buds. It contains sugar to nourish the plants.)

Work in pairs.

Now you will work in pairs. Open your notebook to page 41 and complete task 3.

Examination.

X. Results.

Let's return to the purpose and objectives of the lesson.

What 3 groups of primroses did you recognize?

Name the early flowering ones herbaceous plants.

Which early flowering shrubs are classified as shrubs? (Wolf bast and hazel)

Name early flowering trees. (Alder and willow)

Where do they grow?
- Why do they bloom first?

Test work in an electronic application.

Now you will work in groups and complete test work in the electronic application.

Examination.

XI. Reflection.

Let's evaluate the work in class. If you think that you have worked to the best of your ability and have unraveled the mystery of spring that awakened the Kingdom of Plants, then take a blossoming flower and stick it on a thawed patch.

If you think that you didn’t work well enough, that you could have done better, take an unopened flower bud.

- I am pleased with you, you pleased me with your blooming flowers, which means that today’s lesson brought a lot of useful knowledge.

During the classes

Organizational moment

She will come after winter, she will give you and me warmth,
Will wake the earth from sleep. What's her name? (Spring.)

U: Every day all living things rejoice more and more at the arrival of spring and the sun. The spring warmth makes everyone feel very good. Spring is an amazing time of year and the fastest time of the year. New day - new events. And the March ones are not at all like the April ones, and the April ones will not be like the May ones. This time of year is glorified in folk songs, in the music of composers, and artists’ canvases depict pictures of native nature and spring landscapes. Many poems, stories, and riddles are dedicated to spring.

Guess what months these riddles are talking about?

A warm south wind blows,
The sun is shining brighter,
The snow is thinning, softening, melting,
The loud rook flies in.
What month is it, who knows? (March)

The river roars furiously
And breaks the ice.
The starling returned to his house,
And in the forest the bear woke up.
A lark trills in the sky.
Who came to us? (April)

The distance of the fields is green,
The nightingale sings,
IN White color the garden is dressed,
The bees are the first to fly
Thunder rumbles.
Guess what month this is? (May)

W: Indeed, today we will talk about the spring months. So, we are heading towards spring. What has changed with the arrival of spring?

D: The sun shines brighter than in winter, it rises higher above the horizon, the days become longer.

During the discussion, the composition “Spring changes in nature” is formed on the board

W: Does the sun warm the earth equally in all spring months?

T: Which spring month is the coldest?

T: What is the warmest month?

D: May. In May, the sun is higher above the horizon, which means it heats the earth's surface more strongly. As it gets warmer, the snow melts. It loosens and turns gray. In March, the first thawed patches appear, in April there are more and more of them, and in May the snow will disappear completely.

T: What happens to reservoirs in the spring?

D: The ice darkens, becomes covered with cracks, and melts. At the end of April, ice drift begins: the ice breaks up and floats down the river. In spring, it is very dangerous to walk on ice. In May, rivers overflow - floods.

U: What is the sky like in spring?

D: The sky is blue, the clouds are white.

T: What precipitation falls in the spring? Analyze your observations recorded in " Workbook"on page 35.

D: We noticed that during the days when we made observations, the air temperature increased daily, snow and rain fell.

U: We will continue to observe, but how do you expect the air temperature to change further and what will the precipitation be like in April and May?

D: The air temperature will rise, it will rain more often, snow less often, and then stop altogether. The first thunderstorm will appear in May. Conclusion : The sun is getting higher and higher above the horizon, so the days are getting longer, the sun is heating up the earth more, so the snow and ice are melting.

U: Our guest today is your old friend, Zinka the titmouse, the heroine of V. Bianka’s stories. She is a big travel lover and very inquisitive. She really liked you, and now she has prepared several tasks for you. I think you can complete the bird's first task.

Task No. 1.

T: a) Arrange the landscapes famous painters in the right order.(Children look at reproductions of paintings by artists at the presentation) In what month do you think these natural phenomena that these artists talked about could have occurred?

D: Savrasov “The Rooks Have Arrived” – in March

I. Levitan “Big Water” – in April

I. Grabar “May Evening” – in May

U: b) People called each month differently. Choose a title for each picture.

T: What literary works tell about spring?

D: “It’s not for nothing that winter is angry...” F. Tyutchev, “The snow is already melting, streams are running...” A. Pleshcheev, “Snowdrops” T. Belozerov, “The snow is no longer the same” and “Streams scatter, puddles spread” -S. Marshak, “Snowdrop” by Andersen, “Titmouse’s Calendar” by V. Bianchi.

Task No. 2. Explain the meaning of proverbs.

a) In spring, day and night change.

b) Martok - put on three trousers.

c) He who sleeps in spring cries in winter.

d) Spring scatters flowers.

Spring changes in plant life.

T: Spring scatters flowers. At the end of February, you and I planted marigold seeds in small pots, we are caring for them and making observations. Now you know what sprouts need to grow. Perhaps primroses also need similar conditions?

D: The spring forest is mysterious and not entirely ordinary, it is full of light, transparent, and can be seen right through. The sun is warming up, the first thawed patches are appearing, and the earth is saturated with moisture. All conditions for plant growth are created.

W: That's right. The bright rays of the sun highlight the carved greenery of the first spring grass, the rich colors of forest plants - primroses: woodland, corydalis, lungwort. People call such plants snowdrops.

There's still snow in the ditch, but I'm already turning blue,
The snow has melted, spring is coming, and I am with her.
A green leaf does not yet revive birch trees in the forest,
And spring reveals all the floral beauty in me.
My days are short, but I drink happiness greedily,
And it is pleasant and gratifying for me to be the chosen one of spring.
N. Kholodovsky.

Teacher: The first spring flowers are popularly called snowdrops. When we see them, we are always overcome by an inexplicable tender feeling that is difficult to express in words. With the appearance of the first snowdrops, you clearly understand that winter has finally passed, since these first modest flowers symbolize the onset of spring. The first flowers appear when there is no foliage in the forest. Nothing prevents plants from receiving the sunlight they need to grow. In addition, after the snow melts, the ground is saturated with moisture, which is also a necessary condition for normal plant development. Low-growing insect-pollinated plants attract the first insects with bright flowers at this time of year

U: All primroses are perennial plants. After their aboveground part dries out at the beginning of summer, they do not die. Living underground organs are preserved in the soil - some have tubers, others have bulbs, and others have more or less thick rhizomes. These organs serve as a reservoir for reserve nutrients, mainly starch. Let's open the textbook and look at the illustrations on pages 74-75. See how the root system of these plants is depicted. It is precisely due to the pre-stocked" building material“They develop so quickly in ephemerods, that’s what they call it.

Tales of Primroses

(speaking by second-graders who prepared reports on flowers)

Common coltsfoot, corydalis, anemone, goose onion, coppice, guillemot, lungwort.

Physical education minute.

U: We are already tired of the winter cold, everyone wants the warmth of spring! In ancient times in Rus', young people went out into the streets and called for Spring - red. We have prepared spring invitations for our guests.

Calls.The sun is coming, the red tree is blooming!
The sun will burn brighter, the summer will be hotter and the winter will be warmer, A spring is nicer.
Rise high, shine far, on dark forests, on damp hillocks,
To the river, to the fields, to the blue seas, to the green garden, to all the people!

U: In spring, changes occur with other plants. Let's open the textbook and find out what transformations occur with trees and shrubs.

Working with textbook text (group work)

T: Read the text on pages of textbook No. 77-78 and answer the questions:

How do trees awaken in the forest? What happens to the kidneys? Which tree starts to bloom first? Which shrubs bloom first? Which tree blooms first: birch or bird cherry? What happens to larch? What other trees have young needles? Which shrub is listed in the Red Book?

Students' stories about the spring changes occurring in willow, bird cherry and bird cherry.

U: Guys, look, there is a letter under our birch tree, apparently Zinka brought it.

“Dear second graders!
I am writing to you with a complaint!
I was beautiful, I was pretty,
She became different from herself!
The young grass on me was trampled, the bushes were broken, the first spring flowers were torn off.
They cut down a birch tree for firewood and made fires for me!
They threw cans, dirty paper, wood chips, and rags at me. I'm complaining!
Former forest clearing."

Task No. 3. Let's help our clearing. How can I do that?

I think we need to tell other guys that primroses should not be picked. I suggest you do creative work entitled “Take care of the primroses” and “Take care of the forest.” Each team does their work, and then we will put it on the board and listen to a story about what you drew on the poster and what you wrote about.

The second group of students perform a similar task on computers.

Summing up the lesson. Discussion of students' work.

Don't pick flowers, there is no life in a bouquet,
Leave it in the ground for life to continue.
You won't find a replacement for them,
No matter how you look, there is no replacement!
Do not rush!
After all, if you pick these flowers,
You won't see beauty anymore!

Corydalis dense A common forest plant is the primrose. Blooms together with blueberries. However, the flower begins to develop in autumn. Then a bud is formed from a small, slightly flattened bulb. During the winter, a stalk grows from it and, as soon as the snow melts, the stalk sticks out of the ground. A few warm days - and the corydalis spreads its inflorescences, keeping “company” with scillas and fireweeds!

Slide 15

Slide description:

Coltsfoot Another yellow flower of early spring. Like little suns, coltsfoot flowers shine across the clay hills and along the banks of streams. In places warmed by the sun, the inflorescences of this herb glow yellow. This herb has a strange name: coltsfoot. And it is connected with the structure of the leaf: on top the leaf is dark green, shiny and smooth, and on the bottom the leaves are covered with a thick layer of whitish hairs. Apply such a leaf to your cheek with the outer side - and you will feel a harsh chill, but now turn the leaf over and apply it with the other side - and you will feel warmth and tenderness. Here's your mother's warmth and your stepmother's coldness! Only in early spring you will not find leaves of this grass. They will appear much later - already in the summer... But scientific name associated with medicinal properties leaves of coltsfoot and means "cough". This excellent cough remedy has been known since ancient times. Young leaves are used for medicinal purposes, and decoctions and tinctures are prepared from them. But this is in the summer, and in the spring - these are little suns on a still dull earth!

Slide 16

Slide description:

Spring clear. A common primrose of our forests. The woodleaf blooms a little later, but its flowers coexist with them for a long time, adding yellow color to the blue palette of the spring forest. In the blue sea of forest, these flowers look like yellow islands. The shiny petals, as if varnished, shine in the sun with golden sparkles. Rabbit lettuce is also sometimes called this plant. Young leaves of chistyaka have been used for spring salads since ancient times, as they contain a large amount of vitamin C. But after flowering, toxic substances are formed in them.

Slide description:

Conclusion: Having studied the life characteristics of our snowdrops, we noticed that their development rhythm is not in harmony with the periodicity of our climate. In fact, these plants retire at the very favorable time years and, conversely, develop in winter, under the snow.

Which trees and shrubs begin to bloom before their leaves appear? (Alder, willow, hazel, wolf's bast)

Divide them into groups of shrubs and trees.

Which tree blooms first? (Alder)

Student reports about trees and shrubs.

Alder- a low tree with a thin and often crooked trunk. The trunk is gray, smooth, the leaves are oval, medium in size. Alder leaves are similar in shape and size to apple tree leaves, the same oval, with a sharp end. In winter, the brown catkins hanging down are clearly visible on the alder tree. They are quite short and dense. In the spring, during flowering, the catkin elongates greatly, and abundant yellow pollen spills out of it. Alder releases pollen very early in the spring, earlier than all other trees.

Which tree blooms next? (Willow)

Willow grows along the banks of forest rivers, along streams, ditches when the forest has not yet become green (in early spring). Willow blooms with yellow downy feathers. A special genus of willow is called pussy willow. A beautiful willow with fluffy, fur-like earrings. It blooms when there is still unmelted snow in the forests. Flowering willow is a sure sign of the arrival of spring.)

Guys, where does willow grow? ? ( Along the banks of rivers).
Hazel- this is a bush. It grows in forests. Its leaves are large, wide, irregularly oval, with numerous teeth along the edge. The hazel tree blooms in early spring, unfurling its lush yellow catkins. And if the wind blows, they sway in different directions and scatter their pollen, which resembles a fine yellow powder.

Let's return to the text of the textbook. Find the answer to the question.

Why are these trees and shrubs the first to bloom after winter dormancy? (They are the very first to begin the movement of sap. The sap rises along the trunks and branches to the buds. It contains sugar to nourish the plants.)

During the classes .

I .Call. Basket of ideas. -Identify the primary idea of primroses-Setting goalsThe music of P.I. Tchaikovsky from the ballet “The Nutcracker” “Waltz of the Flowers” (or the voices of birds) sounds

Run away, streams,

Spread, puddles,

Get out, ants,

After the winter cold!

A bear sneaks through

Through the dead wood.

The birds began to sing songs,

And the snowdrop blossomed.

Today we are going to the forest forearly flowering plants. -How do you understand the expression “early flowering plants" ?(Children's answers: first spring flowers, snowdrops) (Teacher: snowdrops or primroses)-So, what is the topic of our lesson? (Primroses or early flowering plants.)(a basket is drawn on the board, on the handle of the basket the word “PRIMFLOWERS” is surrounded by photographs of different flowers) -What flowers will we collect in our basket? Offer.(all the flowers named by the children are collected)-Are all these flowers primroses? (Not sure) -What is the purpose of our lesson?(Our goal is to figure out whether all the flowers are needed in the basket?)

II .Comprehension On each desk in front of you there are 6 pieces of paper. Each piece of paper contains a text describing the plant. There is a photograph of this plant.Your task : Read the plant descriptions carefully. Then consult with your desk neighbor and choose those that are primroses. Set them aside in a separate pile.Study the texts for about 10 minutes.Coltsfoot The snow has just melted, the ground is still bare, and in the sunny heat the first yellow flowers appeared on bare stems. It’s as if small bright light bulbs lit up and signaled: spring has come! This is coltsfoot. The leaves of the coltsfoot appear much later than the yellow inflorescences. The leaves are large and unusual: on top they are green and hard, like the stepmother, and below are whitish, with fibers, soft and tender, like the mother. Hence the name of the flower: coltsfoot.Anemone. The spring breeze has not yet driven all the snow from the forest clearings, but at the edge of the forest, under the bushes, the carved leaves of the skirt and the flowers of the snowdrop anemone are already swaying in the wind. Anemones come with both white flowers and yellow flowers. Anemone was called anemone because its flowers on thin stems sway even from a very weak wind.Clean. As soon as the snow melts and streams of melt water run across the spring meadow, the very first flower - the clear flower - blooms in the meadow. These flowers open only on a clear sunny day. You will come to a spring meadow in the evening and you will not notice any flowers - they have closed for the night. This is how flowers save themselves from the night cold and bad weather. Once upon a time, the juice of this plant was used to reduce warts. This is where the name came from - cleanser, supposedly cleanses the skin.

Common liverwort.

In spring thawed areas, small purple flowers appear among the snow. You are so happy about these delicate flowers on the first days of April - the whole forest seems to come to life, welcoming them. Blooming flowers look like bowls. At night or before rain, the flower bowls bow to the ground and close.Since the leaves of the liverwort resemble the liver in shape, ancient pharmacists used it to treat diseases of this organ. Hence its name - liverwort.

Chicory

Chicory – Compositae perennial. The entire plant contains milky sap. On a tall, straight stem covered with hairs, alternate leaves are located. Chicory flowers are blue, but come in pink and white colors. Chicory blooms in summer, and the fruits ripen from late summer to mid-autumn.

Such a wonderful plant as chicory is widely used to treat many diseases. Bells Summer would not be so loved by Russians if it were not decorated with beautiful forest and wildflowers. There are many flowers that can be called the personification of Russian summer. Our bell is one of these flowers. The campanula flower looks like a bell. For the bell, blue is the most “favorite” color. Bells have long been loved in Rus'. People call them by the following names: balabolki, bells, bells, tambourines, eagles, bell. The bell is listed in the Red Book.

Work in pairs. Examination. What plants do you classify as primroses?

Physical education minute. ( C Singapore) Children stand in two circles: internal and external. They move in different directions to the music. Stop the music, stop the kids. Couples have formed. A question is asked, the couple discusses the answer. The one with (for example) a pink bow, etc. answers. Questions:

1. Guess what month the riddle is about?
The sun is shining brighter,
The snow is thinning, softening, melting,
The loud rook flies in.
What month is it, who knows? (March)

By what spring signs did you know that it was March?(highlight; bright sun, snow melts, soil is saturated with moisture)

2 .The river roars furiously
And breaks the ice.
The starling returned to his house,
And in the forest the bear woke up.
A lark trills in the sky.
Who came to us? (April)

By what spring signs did you know that it was April?

3. What is the difference between the word root and the word rhizome (a thickened root or a root in the form of an onion)? (Remember from the Russian language lesson the analysis of words: mustache-usishchi, eyes-eyes, etc.)They sit down to the music. Continuation of work on the topic. You have a sheet of work on your desk. You need to draw a thread to make a true statement.

For early flowering it is necessary

So, lots of sunlight and lots of moisture in the soil ...It is these conditions that primroses need for early flowering.The roots of primroses are not roots, they arerhizomes. This is a whole pantry; this root stores the nutrients that have accumulated over the winter and are necessary for the plant to feed.Guys, of course there are a lot of primroses in nature. These are not only the ones we talked about.(Showing some of them).Primroses areunder guard states Many of them are inRed Book. If you are in the forest, there is no need to tear them.Slide show.III .Reflection. Sinkwine. Work in pairs.
