Today in the lesson we will get acquainted with the sense organs that are present in our body.

Work on the topic.

The game "Wonderful bag". The organ of vision.

The bag contains various items: a cube, a bubble, a toy - a spatula, a booklet, a brush, etc. All items must be different in color, shape, made of different materials.

I have a wonderful bag containing many different items. Who can determine what it is and what it is? (Children describe the subject without looking at it)

What color is this item?

Why can't we tell? (Do not see)

Now let's take it out of the bag and see.

What helped you?

The eyes are the organ of vision that helps to see everything around us. (Slide 2)

Do you think you need to protect your eyes? Why? (Answers of children. It is possible to draw up rules on how to protect your eyes)

The eyes are the organ of vision. They are placed in the cavities of the skull - the eye sockets, protected by movable eyelids - upper and lower. There are eyelashes on the eyelids. Eyelids and eyelashes protect the eyes from strong wind, dust. Eyebrows prevent beads of sweat protruding from the forehead from flowing into the eyes. If a speck gets into the eye, then tears come out. They moisturize the surface of the eye, wash away all foreign particles and kill germs. The eye consists of the pupil, lens, iris, and optic nerve.

Vision is the ability to perceive the size, shape, color of objects and their

location.

- Now we will play a little with you again. The game is called "Guess the Neighbor's Voice". One of you comes out and turns your back to the class, and the rest will take turns speaking the rules we have drawn up. The driver must determine whose voice he hears. (3-4 people are involved)

- What helped the presenters guess? (Slide 4)

- Our ear consists of three parts: outer, middle, inner. What we call the ear is the part of the ear - the auricle. It allows you to pick up sounds. The ear canal goes inside, ending with the eardrum. This is the outer ear. The middle ear contains three bones. They transmit vibrations to the inner ear, where the endings of the auditory nerve are located. Through the auditory nerve, excitation is transmitted to the brain.

- Think about the rules for caring for your ears? Need to protect your ears?

Statements of children.

Hearing is a person's ability to perceive sound waves.

3. Working with the tutorial. Olfactory organ.

And now all of you will close your eyes, I will carry the thing around the classroom, and you will determine what it is. (It is advisable to get an orange or tangerine, they have a persistent smell)

What? How did you know?

Open the textbooks to page 19. Read which senses help you smell?

What is the name of this sense organ? (Organ of smell, slide 5)

Odorous substances along with the inhaled air enter the nasal cavity. In the upper part of the nasal cavity are the sensory endings of the olfactory nerves. Odorous substances irritate these endings, excitement is transmitted to the brain and the person smells.

Do you think there are people who come up with smells? Who are they?

Smell is the ability to smell.

Child's speech: Perfumer - a person involved in the preparation of perfume compositions, the creation of ideas for new fragrances and / or the sale of perfumery. Each major perfumery and cosmetics company has its own perfumer. He (and more often - she) is engaged in the preparation of perfume compositions. The head perfumer (“Nose”) in many countries is a key figure in a perfume company in the process of creating a new composition, or in reproducing the traditional scent of a perfume product with new ingredients.

4.The organ of taste

Now let's remember what helps us to determine the taste of candy, lemon, salted tomato, mustard? (Tongue)

Read about this organ on page 22.

What is it called?

The tongue is covered with a mucous membrane, in which special taste buds are located. Food irritates the tongue and we taste it. The organs of sight and smell help the tongue determine the quality of food. (Slide 6)

The tongue helps to distinguish the taste of food.

5. The organ of touch. Game "Find out what it is?"

And so we have one more, the last sense organ. Now I will ask 2 people to come up to me. I will blindfold one of them, and the other will touch his hand with various objects. The one who, with his eyes closed, must guess what touched him. (You need to have cotton wool or a brush for drawing, a prickly object (comb), a warm object (heated), heavy (a weight, a weight).

What do you feel? (Heat, pain, cold)

What helps to determine which item it is?

With the help of the skin, you were able to determine the properties of objects: temperature, their severity. The skin helps to sense various touches. Skin is the organ of touch. (Slide 7)

Guys, do you think our skin needs care? Which one? (Children's answers)

Touch is a person's ability to feel touch.

6. Work in a workbook.

Lesson summary.

We talked today about the external senses. Let's remember what they are called? You can offer to fill out pre-prepared cards, for example:

Write the senses.

ear -____________ tongue - ______________ eye - ________________

nose - ____________ skin - __________

and check Slide 8

What role do they play for a person?

With these organs we can feel the world around us. The sense organs must be treated with care. For the senses, colds and smoking are harmful. Therefore, protect yourself from colds, temper your body, avoid bad habits, lead only a healthy lifestyle.

- Did you like the tutorial?

- You worked well. Well done.

Additionally, you can offer interesting data about the sixth sense.

Previously, it was believed that a person has five senses: sight, hearing, taste, smell, touch. And only poets who somehow differently, more subtly, more deeply perceive the world, were endowed with a “sixth sense”. Is it correct?

Close your eyes and stand in some position, then "at attention", and then again in the same position. Which of the five senses mentioned above allowed you to repeat the movement?

It was a “sixth sense” - kinesthetic, that is, a sense of movement caused by irritation of special receptors (end formations of nerve fibers) embedded in muscles, tendons, and joints.

When walking, dancing, cycling, you feel a change in speed or direction of your movement thanks to the vestibular apparatus of the inner ear. It is he who perceives the change in the position of the head and the direction of movement of the body.

In addition, we experience hunger, thirst, abdominal pain, and so on.

All these are so-called interoreceptive (from the Latin words: "interior" - internal and "reception" - reception) feelings.

So, it turns out, how many “sixth senses” any person, and not just a poet, has, although in all these cases it is more correct to speak about sensations and analyzers, and not about feelings and sense organs. The "sixth sense" that poets talk about is a sense of beauty and intuition. We have already written about intuition.

Feelings of perception. We obtain information about the world around us with the help of 5 senses of perception: Sight. Hearing. Smell. Touch. Taste. Senses. Not all people have the same sense of perception. They differ especially sharply in the degree of development of the sense of perception in the animal kingdom. Most of all information gives a person vision. In the navy, signalmen transmit messages by means of flags. The eyes of a giant squid are as large as the steering wheel of a car. The reflected light passes through the retina twice. With the help of hearing, we distinguish sounds. In terms of importance to humans, hearing is second only to sight. - Senses.ppt

AND NOW, UNKNOWN, WE WILL TELL YOU ABOUT OUR SENSE BODIES.

REMEMBER: THERE ARE FIVE OF THEM!

Two Yegorki live near the hill. They live amicably, but do not look at each other.

Why does a man need eyes?

The iris of the eyes is different for all people (gray, brown, blue). And the black dot in the middle is the pupil. He helps us see around. What are eyelashes for? Eyebrows? Eyelids?

Five brothers are inseparable, they are never bored together. They work with a pen, a saw, a spoon, and an ax.

Touch is a property of human skin. The most sensitive skin on the fingertips.

With our fingers we touch objects, recognize them by touch, play with them, work.

And here, Dunno, the rules of hand care. 1. Clean your hands with soap and water. 2. Protect from bruises and cuts. 3. Don't touch hot objects. 4. Cut your nails on time. 5. Do gymnastics for fingers and hands. 6. Wear mittens in freezing weather.

An ear- organ of hearing. The organ of hearing perceives sound. With our ear we hear human speech, birdsong, music and rustling, we distinguish the sounds of natural phenomena.

With the help of our eyes, we learn about the world around us. We see objects, distinguish their color, shape, volume. Eyes - it is the organ of vision. Eyebrows and eyelashes - protect eyes from dust and harsh light. Brows protect the eyes from the sweat from the forehead. Tears moisturize and warm the eye and destroy harmful microbes.

Tongue Is the organ of taste. The tip of the tongue mostly tastes sweet. The edges of the tongue taste salty and sour, and the base feels bitter. A person distinguishes about 10,000 tastes with the tongue. Together with this, the tongue helps to swallow food.

Leather - organ of touch. The skin is a very important sensory organ. With its help, we feel touch, pain, warmth and cold.

• Protect your eyes from foreign objects.
• Don't watch TV for long.
• My ears are daily cleaned with soap and water.
• Do not clean your ears with sharp or hard objects.

Sensory organs The following senses are distinguished in humans: sight (eyes), hearing (ear), smell (nose), taste (tongue) and touch (skin). The sense organs are specialized peripheral formations that provide the perception of external stimuli acting on the body. Due to highly specialized excitability, each sense organ provides the perception of only certain types of stimuli. They include receptors - specific nerve formations that are the end of sensory nerve fibers, capable of being excited by the action of an irritant.

Peripheral section The peripheral section is represented by receptors - sensitive nerve endings that have selective sensitivity only to a certain type of stimulus. Receptors are part of the corresponding sense organs. In complex sensory organs, in addition to receptors, there are also auxiliary structures that provide a better perception of the stimulus, and also perform protective, supporting and other functions

Receptors Receptors (from Latin receptor - receiving) are the endings of sensitive nerve fibers or specialized cells (retina of the eye, inner ear, etc.) that transform irritations perceived from the outside or from the internal environment of the body into nervous excitement transmitted to the central nervous system.

Central section The central section of the analyzer is a specific area of \u200b\u200bthe brain where the incoming sensory information is analyzed and synthesized and converted into a specific sensation (visual, olfactory, etc.) A prerequisite for the normal functioning of the analyzer is the integrity of each of its three sections.

The organ of vision The greatest amount of information about the external world is obtained by a person with the help of the organ of vision - the eye, which consists of an eyeball and an auxiliary apparatus. Appendages and parts of the eye Structure Function Eyebrows Hair, growing from the inner to the outer corner of the eye Remove sweat from the forehead Eyelids Skin folds with eyelashes Protect eyes from light rays, dust Lacrimal apparatus Tear gland and lacrimal ducts Tears moisten, cleanse, disinfect eyes

Hygiene of vision Protect eyes from mechanical influences Read in a well-lit room Keep the book at a distance of cm from the eyes The light should fall from the left Do not lean too much towards the book, this can lead to the development of myopia Do not read in moving vehicles and while eating

Why does a person need senses? You learned that without analyzers (sense organs), the processes of adaptation of the human body to the constantly changing conditions of the environment and internal environment would be impossible. Our visual analyzer, our eyes, is an extremely complex and amazing gift of nature. In a very simplified way, we can say that the human eye is, ultimately, a device for receiving and processing light information, and its closest technical analogue is a digital video camera. Treat your eyes carefully and attentively, just as carefully as you treat your expensive photo and video devices!

Cinquain There are 5 lines in cinquain. 1 - concept (one word); 2 - adjectives that reveal the meaning of the concept (two words); 3 - verbs showing the action of the concept (three words); 4 - a sentence with a semantic nature (of four words); 5 is a noun showing your attitude to the concept (one word).
