MBOU "School No. 33", Ryazan This wonderful world Author: Nikishova Svetlana Nikolaevna teacher primary school 1 qualification category Today you will learn about the most unusual trees that appeared many centuries ago UNUSUAL TREES There are about 100,000 various kinds trees, including a quarter of all living plant species on Earth. But among the billions of trees around the world, there are completely unique and amazing representatives. Let's get acquainted with some of them. METHUSELAH

Until 2013, the Methuselah tree, discovered by botanist Edmund Schulman in 1953, was considered the oldest single tree on Earth. Its age is 4846 years. This tree grows in the White Mountains of California (North America) and belongs to the species Pinus pine.

angel oak

In the USA, in the state of South Carolina, an oak has been growing for 1500 years, which is called the Angel Oak. The approximate height of this giant is 20 meters, the trunk is 2.7 meters in diameter, and the longest branch is 27 meters. It is located in a remote wooded area of John's Island.

Mendocino Tree

The highest tree on the planet. Between December 1996 and August 2000, it was the tallest tree in the world, it was discovered in the city of Montgomery Woods.

Thule - the thickest tree in the world Yew - the oldest tree in Europe The age of the yew growing in the cemetery of the village of Llangerny in North Wales is also estimated to be at least 4000 years old. The tree was able to survive for so long because it constantly put out new shoots. It is difficult to determine the thickness of the tree, because it consists of several trunks, and the tree reaches a height of 10.75 m. The rainbow eucalyptus is the brightest tree on the planet The rainbow eucalyptus is the only eucalyptus species that grows in the northern hemisphere. In addition to the fact that eucalyptus grows up to 70 meters in height, it also shines with all the colors of the rainbow: its bark can be painted in yellow, green, orange and even purple Wisteria is the most beautiful tree in the world An ancient and extremely beautiful plant... Wisterias as a whole are a series of large woody deciduous vines. Most often, wisteria is called the type of Wisteria sinensis, which grows in Japan, and some other species. A well-developed perennial plant has a height of up to 15-18 m, with drooping liana branches, pinnate leaves up to 30 cm long, with 7-13 leaves. It blooms in spring at the end of March - purple fragrant flowers are formed, collected in overhanging brushes. Wisteria, or wisteria, is one of the most beautiful climbing plants, which is a large deciduous vine with a hard lignified trunk. Wisteria flowers, which have a delicate sweetish aroma, are collected in large hanging brushes of various colors: white, blue, purple, violet-blue, lilac, pink or purple.

Wisteria flowers, which have a delicate sweetish aroma, are collected in large hanging brushes of various colors: white, blue, purple, violet-blue, lilac, pink or purple. The height of this plant reaches 15 meters, which allows you to create huge frames to support the vines. Sequoia Trees, were so named after the leader of the Cherokee Sequoia tribe. This tribe formerly occupied the lands of the state of California, considering the huge thick trunks of trees to be the dwellings of tree spirits. Indeed, looking at the trunks of sequoias, it is easy to imagine how someone lives inside - they are very voluminous. Their height is more than 100 meters, and some trees are thousands of years old!

Peach palm This tree is inherent in Central and South America , although its homeland is Costa Rica and Nicaragua. The peach palm is armed with rows of black sharp thorns, which are arranged in rings along the entire trunk from the roots to the top of the tree. Usually these palms grow up to about 20 meters. Leaves reach 3 meters in length. Native Americans used to eat the fruits of this palm after they fermented. The fermented fruit of the peach palm remains a popular delicacy to this day. Bottle Tree The Namibian bottle tree is one of the deadliest trees on earth. The milky sap of the plant is highly poisonous and was used in the past by Bushmen as a poison for arrowheads. It was so named because of the shape of its trunk, in addition, this tree usually grows in the mountainous regions of the deserts of Namibia, which makes its resemblance to a bottle just amazing. The flowers of the Bottle Tree have been described as "beautiful". The flowers are usually pink or white, fading to dark red towards the center. Jaboticaba This plant belongs to the Myrtaceae family. It is called jaboticaba, or Brazilian grape tree. It is fruitful and cultivated in tropical latitudes. The plant has small leaves that are distinguished by a myrtle aroma. It can grow up to 12 meters, but on plantations it does not exceed five. Their fruits do not appear at the ends of the branches, but on the trunk itself. - Walking trees Near Lake Baikal there are also unusual plants that are among the sights of this area. These are ordinary larches and pines, which differ in their roots. They protrude from the sandy soil. Over the years, the wind has blown away the sand, and the roots have been exposed for several meters. But a complex root system helps the tree to stay on the surface. From the outside it looks like the plants are standing on stilts. The most famous grove of "walking trees" grows in Peschanaya Bay. At this point, the roots go out more than two meters. Bombucks These trees are very hard to find and there is only one specific place to see them when traveling through Southeast Asia. Trees are the most distinctive feature of Ta Prohm Temple. Bombax roots entwine the ancient temple, and the trees themselves grow to impressive heights. Blood of the Dragon BAOBAB These magnificent trees growing in Madagascar are over 1000 years old. The baobab is an endangered tree species. Many trees of this species reach over 80 meters in height, and their trunks grow up to 25 meters in girth. The swollen trunks of the baobabs are a source of water, supplying it during the dry season. Baobab flowers are in bloom for only 24 hours. "Underwater" mangrove tree

Mangroves are trees that grow in the sea. Rather, on the verge between the coast and the sea.

WOOD - BASKET This is one of the most famous copies of Axel Erlandson's Tree Circus. Born in 1884, Axel was the son of Swedish immigrants who settled in Canada and lived by growing legumes and grains. They say that it was this activity, or rather, the intricate appearance of intertwining flexible stems, that inspired Erlandson to experiment with trees. 40 fruit tree This amazing project by Sam van Eyken will delight any fruit lover. On one tree, an artist from New York managed to grow 40 different types of stone fruits. In the spring, the tree blooms in various shades of pink, crimson and white, and bears fruit in the summer.

In the Khanty-Mansiysk Autonomous Okrug, where I was born and live, the people of Khanty and Mansi live. Once at the Feast of the North, I saw reindeer, I liked them very much. I wanted to know more about these treasures of the north and decided to spend research work on the theme "Reindeer". Object of study: reindeer. Subject of study: dependence of Khanty and Mansi on reindeer. Purpose: to study the features of the lifestyle of the reindeer and its significance in human life. Hypothesis: the reindeer is a unique animal, because it “gives” all of itself to a person.

Appearance of the animal

Having studied the literature on the topic, I found out that the wild reindeer is the most numerous species of artiodactyl animals. This is a very peculiar deer. The reindeer has an elongated body and neck, relatively short legs. The body length is 150-210 cm from the tail to the tip of the muzzle, the height at the withers is 110-120 cm. The weight of the female is 60-100 kg, the male is 90-180 kg, and the weight of the newborn deer is 4-6 kg. The deer has a small tail 10-15 cm, for comparison, the ear is 9-12 cm. The life expectancy of a deer is 18-20 years.

Slide 7

The muzzle and the space between the nostrils are covered with hair. This makes it easier for the deer to dig through the snow. The deer has the best developed sense of smell, which works even in severe frost. The animal smells reindeer moss even through a thick layer of snow. The structure of the legs is peculiar: the hooves of the thumbs form a kind of large spoon, convenient for raking snow when searching for reindeer moss. Lateral hooves, having 4 toes, are widely spaced forward, which increases the surface of the foot. Thanks to this, the reindeer easily passes through loose snow and swamps. Both males and females have large, annually shed horns. The males use them in the battle for the females, and the female to protect the deer and the place where she digs for food. The size and number of antler processes increase with age. Winter fur is long, a thick mane forms on the neck. The thick core of the hair is filled with air, so the hair is light, brittle, but the fur is very warm. Male reindeer have an inflatable leathery pouch around their neck that amplifies the sounds made by the reindeer during the rut.

Reindeer nutrition and lifestyle

Reindeer are herbivores. They feed on any available plant food. In summer - berries (cloudberries, blueberries, lingonberries), grass, tree leaves, lichens, mushrooms (favorite delicacy). In winter they eat reindeer moss, digging it out from under the snow (do not eat it in summer, because it is dry). Willingly consume lemmings, bird eggs. They love salt. They live in fairly large herds. For communication use mooing and roaring. They migrate. In summer, deer move along the tundra to the seashore, where they drink salt water and take a break from midges and mosquitoes. In winter they go to the forests. The main enemy of the reindeer is the tundra wolf.

Slide 9

Everyone is well aware of this Christmas motif - reindeer harnessed to Santa's sleigh. For many tribes, this deer has become an indispensable assistant. It acts as a vehicle, and is also a source of food and material for tailoring. “The deer is our father: he carries us, feeds and clothes us,” say the Khanty and Mansi. There is no such animal in nature that could be used by humanity in such a multifunctional way as the reindeer.

Slide 10

A hundred years ago, the reindeer almost completely ensured the possibility of human existence in the Far North. I did a little research on what people “take” from a deer: The deer keeps the dwelling warm: the Khanty and Mansi cover their dwelling - chum - with deer skins. They hold heat well and do not let moisture through. Deer skins served as sheets, they were used to sew sleeping bags, they were used as “floor covering” - this is also for warmth. Clothing and footwear of the Khanty and Mansi were sewn from deer skins. Of course, any frosts are not terrible in such clothes and shoes, reindeer herders wear them even now. Women sewed clothes and shoes using threads spun from deer veins. Jewelry and amulets are made from bones and nails of hooves. Hooves and phalanxes served as toys for children. Deer fat is a good remedy for colds, and blood helps with scurvy. Deer serve as food for people. Deer meat is clean, delicious. In the diet of the Khanty and Mansi, they use not only deer meat, but also milk. It is more saturated with fats, proteins, minerals than cow and even goat. From the skins taken from the legs, they make skins for skis and mittens.

Reindeer and man

Reindeer were used as draft labor. The distances were long, it was difficult to walk. Children were also taken from the tundra to school on reindeer. There were also postal deer, they, under the guidance of an experienced reindeer herder-postman, brought mail. Today, many Khanty and Mansi take part in reindeer sleigh races. You can't harness every reindeer. They are being selected. Reindeer training for races begins long before the competition and requires a lot of time and patience.

Reindeer in medicine

There have been legends about deer since ancient times. It was believed that antlers (young deer horns) bring a person healing from all diseases and eternal youth. Modern medicine has confirmed the healing properties of antlers. Currently, two drugs pantocrine and velcornin have been developed from antlers.

slide 13

Khanty and Mansi carried legends, fairy tales, riddles and proverbs about the reindeer through the centuries. The deer is an image of kindness in folklore. In fairy tales, a deer is called a “good old man”, “strong young man”, an important woman is called a “beautiful girl”. The deer is often found in proverbs and sayings. For example, where two deer pass, there is a great road for us; a fool takes a horse for a deer. “The deer teaches” - a saying means that in life it does not always work out as planned. Most of the riddles are closely related to reindeer herding: fur in summer, birch bark in winter (deer antlers); the one who writes does not have time to write down, the one who counts does not have time to count (Traces of deer); not a tree, but a knotty (Deer).

Conclusion

Working on this topic, I found out that the reindeer is really a unique animal - a treasure of the North. But like any treasure, it must be protected and multiplied. Unfortunately, in our time, poaching is widespread, the number of deer is becoming smaller. But this is wrong. Man must take care of everything that nature has created.

Stone houses in Africa

The houses are covered with thatched roofs. Such a house keeps cool well, you can hide in it from the hot African sun.

cave houses

Some of the old houses of this village in Cappadocia (Turkey) are simply hollowed out in the rocks and resemble an anthill.

Bamboo and reed huts.

It's warm in Thailand, its light huts locals and to this day they build from bamboo and reeds.

And if there is a sandy Asian desert around? Many peoples living there (for example, Kazakhs, Kirghiz) from ancient times moved with their herds from one pasture to another, without having a permanent place of residence. And now nomadic pastoralists carry their houses with them in the old fashioned way, like tourists carry their tents.

Such a tent is called a "yurt", it is round. The nomads will arrange long sticks-poles, tie them together in the manner of a cage, cover them with felt on all sides (a very dense woolen material, felt boots are also made from it) - and the house is ready in just a few hours.

In the far North, where trees, if any, are very small (they are called so - dwarf ones), there is also not much to build from. But you can’t live without a house - after all, there are terrible frosts in the North! The dwelling of the northerners - the Chukchi - is called "yaranga".

It looks like a yurt, but it is pointed, the walls in it are made of deer skins. In the event of a move, this dwelling could be easily disassembled, transported, and then reassembled.

An Indian wigwam looks like a yaranga, and it is not surprising - these peoples once had common ancestors a very long time ago. Indian houses - wigwams - were built in the form of a dome from thin tree trunks and covered on top with branches, bark, skins or multi-colored woven rugs (mats).

An igloo is a house made of snow.

And the Canadian Eskimos build from what itself falls from the sky! The igloo is their snowy home, it protects from wind and bad weather, and from the inside it is lined with animal skins for warmth. Here, probably, what masters built the palace of the Snow Queen!
