Introduction
Immerse yourself in the wonderful world of mammals and you will discover many new things. Here everyone, even a well-informed and erudite person, will find unknown and sometimes intriguing facts from the animal world. The relevance of the chosen topic can be revealed by one famous statement George Eliot "Animals are very nice friends..."
We undertook this work in order to expand our knowledge in such a section of the animal world as Mammals. In this work, we will describe some mammals, tell interesting information about them.
The purpose of the project: acquaintance with amazing mammals.
Tasks:
Find information about common features mammals;
Discover mammals you never knew existed
Collect interesting, unknown facts about mammals we already know
Before starting work on a project on this topic, we, students of grade 1a, assumed that mammals are four-legged animals, in which the body is raised high above the ground, and the limbs are located under the body. One of the hallmarks of mammals is the presence of hair. The habitat of mammals is land. To confirm our hypothesis, we used the following research methods:
1. Observation.
2. Study of literature.
3. Comparison.
4. Sociological survey
5. Systematization of knowledge, analysis and explanation of research data.
So, we begin our virtual journey through the world of mammals!
Theoretical part
All animals that feed their young with milk are called mammals. There are a lot of them, and they are very different: from a baby mouse to a giant elephant. Humans are also mammals.
Nowadays, about four thousand species of mammals live on the entire globe. Many of them inhabit vast expanses of land or the World Ocean and still number in the hundreds of thousands and millions, and some have become so rare and few in number that scientists count them in the thousands, hundreds and even tens.
Despite all the variety of forms, mammals have a number of common features.
Most mammals are quadrupeds with their torsos high above the ground and their limbs below their torso. This body structure contributes to their more perfect movement on land. Mammals have a well-defined neck, which allows the head to have a high degree of mobility. In connection with the adaptation to movement in different environments, the limbs of mammals have different shapes. For example, in whales and dolphins, the limbs are changed into flippers, and in bats, into wings.
Modern mammals are divided into 19 orders. Among them are: oviparous, marsupials, insectivores, bats, cetaceans, carnivores, paired and equids, primates.
We will name the most important orders of mammals:
Insectivores have medium or small body sizes (mole, hedgehog, shrew).
Rodents have a body of small or medium size, strongly developed, constantly growing incisors; have high fertility, mainly herbivores (squirrels, beavers, ground squirrels, mice, rats).
Lagomorphs have two pairs of incisors, body size is small (hare, rabbit, pika).
Carnivores have well-developed fangs and predatory teeth, feed mainly on animal food (wolves, bears, martens, tigers).
Pinnipeds spend most of their lives in the water, limbs are modified into flippers (walrus, seal, fur seal).
Cetaceans live in water, have a large body; the forelimbs are modified into flippers, while the hind limbs are absent; move with the help of a powerful tail; There are toothed whales (sperm whale, dolphins) and baleen whales (blue whale).
Artiodactyls have a body of medium or large size
(cow, elk, wild boar, hippopotamus).
Odd-toed ungulates have large body sizes, hooves (horse, donkey, zebra).
Primates have different body sizes, the most numerous family is monkey-like, which includes macaques, baboons, monkeys.
Now we will tell you about the most amazing mammals.
Blue whale
Among modern mammals, the largest is the blue whale, whose body length exceeds 33 meters and weighs up to 160 tons, which corresponds to the weight of 30 elephants or 150 bulls. One tongue of such a giant weighs 4 tons - like a big elephant!
Blue whale - the largest mammal not only of our time, but also ever lived on Earth. It is larger than even the largest dinosaur. Plus the blue whaleloudest mammal -
This. It can make sounds that can be heard at a distance of 850 km.
African elephant
largest land mammal
– this is a male African elephant . The largest elephant had a height of 3.96 m and weighed over 12 tons. The amazing thing about elephants is that they can hear with their feet just as well as with their ears, picking up sounds passing through the ground. It is possible that elephants resort to this method of communication when there is too much noise above the ground, for example, airplanes fly by.
Giraffe
With 
tallest of mammals- Thisgiraffe
having a height of 6.1 m. The neck of giraffes is unusually long, despite the fact that they, like almost all other mammals, have only seven cervical vertebrae. Giraffes can run fast and, in case of urgent need, reach a speed of 55 km / h at a gallop, that is, they can overtake a racehorse over short distances. However, giraffes walk slowly.
Bat
The smallest of the mammals is the bat from Thailand, which bears the name pig-nosed Kitty Bat, which has a length of only 2.9-3.3 cm and weighs only 1.7-2 g. This mouse is inferior in size to many insects and snails.
rocky squirrel
Rocky squirrel can live up to 100 days without water
The record for the ability to go without water is not held by a camel, but by a rocky squirrel from southern Mexico. This small animal can live without water for up to 100 days.
Cheetah
The fastest of mammals is cheetah, which develops a speed of 96 km per hour over short distances, there is also data on 105-115 km per hour.
Platypus
The platypus, which lives in Australia, can be safely called one of the most amazing animals on our planet. When the first skin of a platypus first came to England (this happened in 1797), at first everyone thought that some joker had sewn a duck's beak onto the skin of an animal that looked like a beaver. When it turned out that the skin was not a fake, the scientists could not decide which group of animals to attribute this creature to. So, the platypus is an amazing mammal that lays eggs, but feeds its cubs with milk.
An amazing creation of nature - a mammal marmoset - the smallest monkey in the world, its body length is about 12cm 15cm tail length.
Organization and research methods
The main place of work on the project was office No. 2 of the MOU PSOSH. Under the guidance of our class teacher, we studied the literature on the topic "Amazing Mammals", conducted a sociological survey among primary school students, teachers, and parents. The students were asked the following questions:
Name the main hallmark mammals?
Is a bat a mammal? Why?
Are whales and dolphins mammals? Why?
Name the fastest mammal?
Name the largest mammal?
Name the smallest of the mammals?
What is the tallest mammal?
As a result, we have collected a wealth of material on this topic.
Research results
As a result of the study, we found that the students of the primary level of the MOU PSOSH are well aware of the distinguishing features of mammals. Many children can name the tallest mammal, the smallest mammal, the fastest, the largest mammal.
As a result of the study, we have expanded our knowledge of mammals. We learned that all mammals are united by the fact that they feed their cubs with milk. Our assumptions that mammals are quadrupeds, in which the body is raised high above the ground, and the limbs are located under the body, and that one of the distinguishing features of mammals is the presence of hair, were confirmed. We also learned that mammals live not only on land, but also in water. We discovered mammals we didn't even know existed; collected interesting facts unknown to us about mammals already familiar to us.
Conclusion
Having studied the materials of books, encyclopedias on our topic, we came to the conclusion that the world of mammals is large and diverse. No encyclopedia is able to tell even briefly about absolutely all representatives of the mammal class. It is possible that scientists have yet to discover new species that are still unknown to science. It is possible that we, students of grade 1a, will become these scientists.
While working on the project, we found out that many species of mammals are endangered. These are the Altai mountain sheep, the Amur tiger, the white-bellied seal, the East Siberian leopard, the polar bear, the bison and many others.
Protecting nature is our duty. All animals without exception have the right to live on this planet, regardless of their size and benefit to humans. Many species of animals have already disappeared from the face of the Earth with the active participation of man. Our task is to preserve the remaining species. Having fed the birds in winter or releasing the caught bug, even the smallest person will be able to make a small contribution to a big deal - nature protection.

The study of the external and internal structure of mammals. MAMMALS - animals (Mammalia), a class of vertebrates, the most famous group of animals, including more than 4600 species of the world fauna. It includes cats, dogs, cows, elephants, mice, whales, people, etc. In the course of evolution, mammals have carried out the widest adaptive radiation, i.e. adapted to a variety of ecological niches.

Description of the slide:
The origin of mammals The ancestors of mammals were undoubtedly ancient Paleozoic reptiles, which had not yet lost some of the structural features of amphibians: skin glands, the location of joints in the limbs (between the lower leg and tarsus and between the forearm and wrist) and, perhaps, a double occipital condyle. Such an ancestral group is considered a subclass of animal-like (Theromorpha).

Description of the slide:
Origin of the domestic cat Where did the domestic cat come from? When did man domesticate this animal? Each of these questions cannot be answered unambiguously, because there are different versions of the origin of the domestic cat in the world. Someone, for example, seriously believes that these wonderful creatures came from outer space. Legend has it that the domestic cat was first born on Noah's Ark. Therefore, before the start of the global flood, such an animal did not exist at all. When the ark floated on the land flooded by the ocean, so many mice and rats bred on it that it began to threaten its other inhabitants. And then Noah turned to the king of beasts for help. According to one version, the lion sneezed and a cat jumped out of his nostril, after which he sneezed a second time and a cat jumped out of his second nostril. The rodents on the ark were having a hard time. According to another version, this pair appeared from the nostrils of a lion after Noah stroked the king of beasts on the forehead. It turns out that the first cats saved humanity from certain death.

Description of the slide:
Origin of felines Origin of wild cats In the Paleocene, a family of primitive predators similar to martens - miacids (Miacidae) was formed. By the middle of the Tertiary period (in the Oligocene), they occupied a dominant position among other terrestrial carnivores, and among them there were seven main families of terrestrial and three families of aquatic predators that are part of the modern predatory order (Carnivora). The Oligocene includes the appearance of Proailurus, a transitional form between viverrids and cats. In the Miocene, it gave way to pseudoailurus (Pseudaelurus), from which two subfamilies of cats originated: cats proper saber-toothed tigers. The domestic cat belongs to the category of mammals, the cat family. This family includes both long-extinct and now existing representatives. In total, 37 species of cats are known. The origin of cats has a long history. About 30-35 million years ago, the ancient predators of the Viviera family reached a great diversity and wide distribution. Some of them served as the initial forms of modern species of wild and domestic cats. The ancient original and, apparently, the main ancestor of all breeds and varieties of domestic cats is considered to be the "wild North African buck" or "Libyan cat". It is also known as the “steppe”, “Nubian”, which received this name from the ancient state of Nubia, located on the territory of present-day Sudan. In the wild, this cat has survived to this day.
9 slide
Description of the slide:
Despite the centuries-old history of the relationship between a cat and a person, it has changed little, unlike other animals. By appearance the domestic cat is remarkably similar to its ancient ancestors. Only a few changes in the structure of the ear, a more pronounced bulge of the temporal bones, a shortening of the muzzle and variations in coloration can be seen. On the other hand, she retained her proud character and independent lifestyle. One can agree with the opinion of researchers that the modern domestic cat, with the exception of some decorative breeds, cannot be considered in the full sense of the home, since it almost completely retains the habits and behavior of wild relatives, only adapting them to new living conditions in the house. Cats are very good at navigating in unfamiliar surroundings, so that, as a rule, they always find their way home without much difficulty. But if it is impossible to return to her former home, she quickly adapts to new conditions and is even able to lead a wild lifestyle.

Description of the slide:
Experiment: "Who is the owner of the cat" All family members were at home, the cat was in another room. At the same time, everyone began to call the cat to him, but the cat ran to only one member of the family - to his mother, because she feeds and cooks for her. As a result of the experiment, we can conclude that the cat considers its mother to be its owner, because she feeds her. Conclusion: If you have got yourself a small pet, take care, feed him, love him, because he is like a family member.

Description of the slide:
A distinctive feature of animals in terms of integument The presence of wool covering the body is a distinctive feature of animals: only they form hair, i.e. filamentous keratinized outgrowths of the skin (epidermis). The main function of the coat is to insulate the body, which facilitates thermoregulation, but it also serves many other purposes, in particular, it protects the skin from damage, and can mask the animal due to its color. Depending on the habitat conditions, the cover changes.

Description of the slide:
SELF PRESERVATION Protective covers. Some animals, such as a hedgehog, are covered with needles and, in case of danger, curl up into a ball, exposing them in all directions. A similar method of protection is used by armadillos, which are able to completely fence themselves off from the outside world with a horny shell, which also protects the body from the sharp thorns of cacti, which are the most common vegetation in the habitats of these animals. The North American porcupine went even further in the development of protective covers. It is not only covered with jagged needles, which, stuck in the body of the enemy, can lead to his death, but also very deftly wields a prickly tail, inflicting quick and accurate blows on the enemy.

Description of the slide:
self-preservation All mammals have developed certain mechanisms of self-preservation, and many have acquired special protective adaptations in the course of evolution. The THREE-BELT ARMADOLE curls up into a ball when an enemy approaches. Vulnerable parts of the body are completely surrounded by bone plates covering its back.

Skeleton In mammals, as in all vertebrates, the skeleton consists of a large number of bones that develop independently and are interconnected by ligaments and connective tissue. In some species, it is deeply specialized, but the principle of its structure is the same for all representatives of the class. This fundamental similarity is clearly seen when comparing extreme variants, such as dolphins with a virtually absent neck, whose vertebrae are paper-thin, and giraffes with the same number, but very elongated cervical vertebrae. The skull of mammals is articulated with the vertebral column by two rounded bony protrusions in its back - the occipital condyles.

27 slide
Description of the slide:
The teeth of the vast majority of mammals are solid structures that develop from special connective tissue (mesoderm) cells - odontoblasts and consist mainly of calcium phosphate (apatite), i.e. chemically very similar to bones. However, calcium phosphate crystallizes and combines with other substances in different ways, so that various dental tissues are formed as a result - dentin, enamel and cementum. Basically, a tooth is made up of dentin. (Elephant tusks and, accordingly, ivory are solid dentin; a small amount of enamel that first covers the end of the tusk is quickly erased.) The cavity in the center of the tooth contains the “pulp” that feeds it from soft connective tissue, blood vessels and nerves.

Characteristic features Artiodactyls This order includes animals of medium and large size with thin long legs ending in two fingers, less often four. The ends of the fingers are dressed in horn covers - hooves. The first finger is always missing. The legs are adapted for movement in one plane parallel to the average longitudinal section of the body. Males (rarely females) of many ungulates have horns. This detachment unites ungulates, characterized by the fact that their third finger reaches the greatest development, through which the axis of the limb passes, while other fingers are poorly developed or completely absent. Odd-toed ungulates do not have clavicles; simple stomach. There is only one pair of nipples (in the inguinal region).

The ruble is interesting Earlier in Russian, the word giraffe was used in the feminine gender - giraffe. People who work with horses are fifty percent less likely to develop diabetes than anyone else. The largest representative of wild horses was the zebra, which had one and a half meters at the withers and about two and a half meters in length. Due to the special location of the eyeballs on the head, horses see 360 degrees, with the exception of two “dead” points: right in front of the forehead and a small area behind the neck. Horses see quite well in the dark, especially clearly distinguish bright objects.
