Slide 10. Trees. (On the tables are cards with the image of trees)

2.-You have cards with the image of trees on your tables. Think about what needs to be done with them.(Divide into groups) .

Divide into two groups: coniferous and deciduous.

- Show a group of trees that have needles instead of leaves. how
let's call this group of trees?

Now you have described the symptoms conifers trees. They're called"essential".(Coniferous trees - spruce, pine).

- Show group deciduous trees. Let's name this group of trees?

Now describe the essential features of deciduous trees.(Availability leaves and crowns)

Next task:

- Divide the trees into two groups: the first group is the trees that grow in our forest, the second group, the trees that do not germinate in our forest.

(children's answers)

Set aside the cards.

Slide 11. Coniferous plants.

H. Practical work with coniferous plants .

What kind coniferous plants you know? What do you know about them? (Leaves are needles;there is no flower, instead of a flower there is a cone; the tree is green all year round.) Want toknow even more? Lesovichok will help with this. He allowed to breaksprig of spruce and pine. Why do you think he was not allowed to pluck a lottwigs? (This can kill the tree).

Pair work . - Consider and compare spruce and pine branches.(twigs
pre-prepared and lie on the desk). Highlight distinctivespruce signs.

Conclusion : Spruce - needles are short, prickly, sit one at a time, trees change themafter 5-6 years.

name features pines.

Conclusion : Pine - needles are long, soft, sit in pairs, live 2-3 years.

The peculiarity of the pine has long been noticed by people and reflected in folkriddles.(Student tells).

I have longer needles than a Christmas tree.

I am growing very straight - in height.

If I'm not on the edge,

Branches only at the top.(Pine)

In pine and spruce forests, the air is very clean. He kills the badbacteria.

And look at this tree. What does it look like? (Back to slide 10 . Trees)

I'm not a pine and I'm not a tree.

Only autumn on the threshold - ( I single out larch )

Every single needle

I'll throw it off the branches right on time.

Find in the textbook on page 38 a tree that looks like a spruce, but without needles in the wintertime. Read what it's called. Who guessed why?

Slide 12. Larch.

In autumn, golden needles, like leaves, fall to the ground, hence thetree name.

Which group of trees does larch belong to? (Larch descends to coniferous trees).

Slide 13. Coniferous trees

Slide 14. Deciduous trees.

Now look at the group of remaining trees.

Remind Lesovichka, what are they called?(deciduous)

Are these the same trees or different ones? How did you know?(They are different in height, stem thickness, leaf shape and color).

What unites them?(The leaves are shed in autumn.)

Physical education:

We walked through the forest

And let's get some rest.

Let's get up and take a deep breath. Let's spread our hands together(spread arms out to the sides ),

Now let's go ahead and play a little.

Miracles in our world:

Children became dwarfs(sit down)

And then everyone stood up together,

We have become giants.(Stand up)

We clap together(clap hands)

We stomp our feet!(stomp feet)

We went to the forest lawn,

Raising your legs higher

Through bushes and hummocks,

Through branches and stumps.

Who walked so high -

Didn't trip, didn't fall.

Well we walked and did not get tired!(We walk in place)

Have you seen how many trees there are around? Have you ever wondered how theyfeel?

4. Independent work in a notebook. Task 1. Page 38.slide 15.

Peer review on slide 15.

5. Creative work of children.

Coniferous trees are one of the most ancient groups of plants, which are about 300 million years old. Representatives of coniferous trees: cypress, yew, cedar, fir, juniper, pine, spruce, etc. Coniferous trees in abundance, in one form or another, grow throughout the globe, in all parts of the world. Often coniferous trees dominate over other plants. The size of an adult coniferous tree can reach 100 meters in height (the tallest coniferous tree is the evergreen Sequoia - 115.2 meters). In addition, representatives of coniferous trees are not only the tallest, but also the thickest - Mexican Taxodium (11.42 meters in diameter), old - Durable Pine (4700 years) and large - Giant Sequoia Dendron (with a volume of 1486.9 m³) flora representatives. In Russia, the most common are spruce, pine, fir, cedar, juniper.

On the topic: methodological developments, presentations and notes

Presentation "Coniferous trees"

The presentation introduces students to the characteristics of coniferous trees, as well as their use in the economy. The presentation can be used in the lessons on the study of the surrounding world in grades 1-2....

In this lesson, the topic "Deciduous and Coniferous Trees" will be considered, which will help students learn about two groups of trees - deciduous and coniferous. Consider their distinguishing features.

Lesson: Deciduous and coniferous trees

As you know, each tree has its own distinctive features. Leaves are one such feature. Sheet- This is one of the main organs of the plant, performing the function of respiration and nutrition. The leaves of trees are very diverse in shape and size.

Birch has small carved leaves.

Linden leaves are shaped like a heart.

Oak leaves will expand at the top of the leaf.

Maple has a wide leaf plate with pointed ends.

Rowan has a complex leaf, on the central petiole there are up to 15 small leaves.

Complex leaf and chestnut. Slightly pointed leaves are connected at the top of the main petiole.

Birch, mountain ash, oak, maple, linden are deciduous trees. They have their own distinctive features.

1) The presence of leaves.

2) In autumn, the color of the leaves changes.

3) All deciduous trees shed their foliage. This phenomenon is called leaf fall.

A large number of treesform a deciduous forest.

Let's get acquainted with some representatives of deciduous trees.

The most powerful tree in the forest is considered oak. Our ancestors considered oak sacred tree. The height of the oak is about 50 meters, the life expectancy is 500 years. But there are centenarians for more than a thousand years. Ripe on oak trees in autumn acorns.

These are rich and nutritious fruits. The squirrel loves to eat acorns, and will hide them in a hollow in reserve. forest bird jay is also a lover of delicious fruits. Rushing for acorns and wild boars, because they need to accumulate fat in order to overwinter the winter.

Our ancestors knew: a lot of acorns on oak - to harsh winter. Wheat should be sown when the oak leaves unfold. And oak is considered a symbol of power and strength. Oak wreaths were awarded to the bravest warriors.

People say about cowardly people: "It trembles like an aspen leaf." In fact, the aspen leaf trembles from the slightest breath of wind. This is due to the structure of the petiole . The aspen petiole is very thin and long, even in calm weather, aspen leaves rustle quietly. In the spring, before the leaves appear on the aspen, earrings appear. People say: "Fluff flew from the aspen, go to the forest for a boletus."

These are mushrooms that love to grow under the aspen. The caps of these mushrooms resemble the autumn color of aspen leaves.

What tree is this riddle about?

Takes from my flower

The bee is the most delicious honey.

And everyone hates me

Remove the thin skin.

This is Linden. Fragrant fragrant linden flowers attract bees. And it is not for nothing that the bees produce linden honey, it has healing properties. Our ancestors went to linden for bast. This is inner part bark. Thin strips were removed from the tree and bast shoes were woven. Linden wood is very soft and white. Furniture, dishes and musical instruments are made from it.

The second group of trees is coniferous. Needles are modified leaves. Coniferous trees include spruce, cedar pine, fir, larch. A forest of coniferous trees is called coniferous. Unlike deciduous trees, coniferous trees do not shed their needles in autumn, so their other name is evergreen.

Spruce is an evergreen coniferous tree. The crown of the tree descends to the very ground, so it is dark and damp in the spruce forests. spruce forests called spruce forests. Spruce roots are located close to the surface of the earth. Therefore, from a strong wind, spruce trees fall, forming impenetrable thickets and windbreaks. It looks like a spruce branch with cones. Cones are oblong.

Spruce is a very interesting and useful tree. Its wood is used to make musical instruments and paper. Coniferous trees emit special substances, they fill the air with a pleasant aroma and purify it. How much joy the green beauty brings to the house under New Year!

Pine is a coniferous tree. The crown of the tree is at the very top, so in pine forests light. Such a forest is called pine forest . The pine has powerful roots, so it is not afraid of strong winds. And pine can grow on rocks and ravines. It looks like a pine branch with a cone.

Pine needles are longer than those of spruce. Needles grow on a branch two together. Cones are short, rounded.

There is a tree with unusual properties among coniferous trees - this larch. Like spruce and pine, larch has needles; in autumn, larch turns yellow and sheds needles like leaves, which is why it is called larch. In the spring, young needles reappear from the buds.

If there are both coniferous and deciduous trees in the forest, such a forest is called mixed.

Trees are the lungs of our planet. By absorbing harmful substances, trees release air and oxygen. Leaves hold fumes and soot. Trees need to be protected.

In the next lesson, the topic "Autumn in the life of plants" will be considered. During the lesson, we will learn about the most important seasonal changes that occur with almost all plants. Let's see how autumn manifests itself, and then find out the role of autumn in plant life.
