RESEARCH ACTIVITY Research activity is understood as the activity of students associated with finding an answer to a creative, research problem with a known solution in advance and presupposing the presence of the main stages characteristic of research in the scientific field: setting a problem, studying a theory related to the chosen topic, putting forward a research hypothesis, selection of methods and practical mastery of them, collection of own material, its analysis and generalization, own conclusions. Any research, no matter in what field of natural sciences or humanities it is carried out, has a similar structure. Such a chain is an integral part of research activity, the norm for its conduct.

Deciphering the individual stages of individual research work: 1. Preparatory stage: 1. Selecting an approximate topic (title) of the work, which sets the direction of the research. The topic is finally formulated when preparing materials for the presentation. It reflects the essence of the work performed 2. Determination of the purpose of the work. Allows the student to imagine exactly what he is going to do and what to achieve when performing the work. The goal may change during the execution of the work, but at each specific moment it is clearly defined. To be completed in writing. 3. Selection of the research object, formation of an experimental and control group. Determined by the purpose of the work, real opportunities. Justified from the point of view of the possibility of obtaining reliable results. 4. Formulation of a working hypothesis. Identification of specific tasks, the solution of which will allow achieving the goal. Strictly related to the stated goal of the work. Determine the stages of work. Allow the student to move consistently, rather than chaotically, towards achieving the goal.

2. Main stage: 1. Search and study of literature on the research topic. Allows you to understand what is already known within the framework of the chosen scientific topic, understand the basic terms, concepts, and compare the views of different authors on the problem. 2. Formation of the chapter: “Literature review.” Strictly structured, logical. Contains only information directly related to the topic of the work. Closely related to the purpose of the work. Contains links to used literature sources. 3. Selection of research methods. Determined by the purpose of the work and the available material and technical base. The number of experiments is justified from the point of view of obtaining reliable results. 4. Carrying out your own research. Analysis of the results obtained. Conducting an experiment or other elements of analysis. Construction of graphs, tables, etc. Comparison of the obtained results with literature data. Determining the reliability of the results obtained. Determining directions for further work. 5.Preparation of a report on the work done in the form of a scientific article. Contains the following sections: introduction to the purpose of the work; chapter: “literature review”; chapter: “materials and methods”; chapter: “results and their discussion” conclusions; list of used literature. 6. Conclusions – strictly structured, succinctly presented results of our own research. They answer the question formulated in the purpose of the work. 7. Preparing the work for presentation Determined by the requirements of the conference or publication where it is planned to present the work.

Slide description:

A typical situation for research activities is when both the teacher and the student become, as it were, “hand in hand” (in contrast to the traditional scheme, where the student and teacher are separated on opposite sides - teaching and being taught, speaking and listening, checking and being tested), the student feels in the teacher, a colleague, an assistant, a mentor. At the same time, the “colleague-colleague” connection is realized. The most important condition for the implementation of student research activities is the individual work of the teacher with the student in a given subject area, associated with mastering the methodology, collecting experimental material and discussing it. At this stage, a very important point arises in correlating the level of the task with the capabilities of the student, monitoring his own assessment of the progress of the work. Thus, research activity involves personal communication between teacher and student. And in the process of personal communication, there is inevitably a departure from the scope of the subject under study. As a result, the second characteristic functional connection is realized - “spiritual mentor - junior comrade”, through which value orientations and moral attitudes are transmitted from teacher to student, which ensures a high educational effect of research activities.

Slide description:

This means that the main goal is to develop the student’s personality, and not to obtain an objectively new result, as in “big” science. If in science the main goal is the production of new knowledge, then in education the goal of research activity is to acquire the functional skill of research as a universal way of mastering reality, developing the ability for a research type of thinking, and activating the student’s personal position in the educational process based on the acquisition of subjectively new knowledge ( i.e. independently acquired knowledge that is new and personally significant for a particular student).

Slide description:

Specifics of implementing research tasks at school. Important restrictions are imposed on the topic, nature and volume of research by the requirements of developmental psychology. Adolescence is characterized by a still low general educational level, an unformed worldview, an underdeveloped ability for independent analysis, and poor concentration. Excessive volume of work and its specialization, which lead to withdrawal into a narrow subject area, can be detrimental to general education and development, which is by far the main task at this age. Therefore, not every research task brought from science is suitable for implementation in educational institutions. Such tasks must satisfy certain requirements, on the basis of which it is possible to establish general principles for designing student research tasks in various fields of knowledge.

Slide description:

Classification of creative works of students in the field of natural sciences and humanities and their types: Problem-abstract - creative works written on the basis of several literary sources, involving a comparison of data from different sources and, on the basis of this, their own interpretation of the problem posed. Experimental - creative works written on the basis performing an experiment described in science and having a known result. They are rather illustrative in nature, suggesting an independent interpretation of the characteristics of the result depending on changes in the initial conditions. Naturalistic and descriptive - creative works aimed at observing and qualitatively describing a phenomenon. May have an element of scientific novelty. A distinctive feature is the lack of correct research methodology. One of the varieties of naturalistic works are works of a socio-ecological orientation. Recently, apparently, another lexical meaning of the term “ecology” has appeared, denoting a social movement aimed at combating anthropogenic environmental pollution. Works performed in this genre often suffer from a lack of a scientific approach. Research - creative works performed using a scientifically correct technique, having their own experimental material obtained using this technique, on the basis of which analysis and conclusions are made about the nature of the phenomenon being studied. A feature of such work is the uncertainty of the results that research can give. A student research project is a statement of fact, confirmation of a hypothesis.

CONCLUSIONS Theoretical and practical significance of the research and its novelty. It is revealed how the results of the research (experiment) influence the development of theory, what practical value they have and what new, previously unknown facts were discovered during the research (experiment). Implementation of research results into practice (replication or distribution). It is shown how the results of the work carried out were reported at conferences, seminars, meetings, and reflected in publications. The following basic requirements are imposed on the report: clarity of construction, logical sequence of presentation of the material, convincing argumentation, brevity and clarity of wording, specific presentation of the results of the work, evidence of conclusions and validity of recommendations .

Research methods: The cartographic research method is an analysis of the geographical conditions of the state using a map. The statistical method is a method for studying the quantitative side of mass social and other phenomena and processes. The statistical method makes it possible to characterize in digital terms the ongoing changes in social processes. The analytical method of research is the analysis of an array of information on any subject or issue. The comparative method of research is the conduct of research by comparing two or more objects with each other. The project method as a means of organizing student research activities. .

Slide description:

Presentation of Research Presentation of research is critical throughout the work. The presence of standards of presentation is a characteristic attribute of research activity and is expressed quite strictly in contrast, for example, to activities in the field of art. There are several such standards in science: abstract, scientific article, oral report, dissertation, monograph, popular article. Each of the standards defines the nature of the language, volume, and structure. When presenting, the leader and student must, from the very beginning, decide on the genre in which he is working and strictly follow its requirements. The most popular genres at modern youth conferences are abstracts, articles, and reports. Moreover, these forms may not contain research works, but, for example, abstracts or descriptive works.

Introduction

Onions are always on our table, but what do we know about them? Yes, perhaps it’s nothing! Nevertheless, this familiar vegetable has a wonderful history. Since ancient times, onions have been an important component of our diet. This seemingly unassuming vegetable, thanks to its pungent taste, has become a hit in the cuisine of almost all nations. Onions turn the most ordinary meal into an exquisite pleasure.

Since ancient times, mankind has appreciated onions justly, as they are one of the few vegetables that do not spoil in winter. In ancient Egypt it was worshiped as a symbol of eternity due to its high concentration of rings and spherical shape. Egyptian artists created images of many vegetables, but only onions received the honor of being made of pure gold! Ancient Greek athletes ate large quantities of onions because they believed that this mysterious food “facilitated blood balance.” It seems that they were trying to purify the blood with this.

After the conquest of Greece by Rome, onions became almost the main product in the diet. In addition, gladiators rubbed their muscles with onion juice. Conquering new territories, onions everywhere became more than just food. Medieval healers prescribed it for headaches and snake bites. As a nutritious food and medicine, it accompanied the Puritans to their promised New World and may have been served on the very first Thanksgiving!

Today, onions are still an important part of the diet. Scientists have discovered that it contains antioxidants that block the development of cancer cells and lower cholesterol levels. Apparently, it was not for nothing that our ancestors instinctively guessed that onions were much more than just a vegetable.

History of the bow:

According to the official version, Asia is considered the birthplace of onions, but it could easily grow as an ornamental plant on absolutely any continent. The history of onions is lost in the mists of time. It is believed that onions were “cultivated” by humans at least 4 thousand years ago. This happened somewhere, most likely in the territory of modern Iran or Afghanistan. Images of onions were found on the walls of the pyramids of ancient Egyptian pharaohs. This plant is mentioned in the cuneiform writing of the ancient Sumerians and in the Bible. Egyptian merchants were the first to bring onions to Europe. This bow appeared in Russia in the 12th century.

There are different types of onions:

Slime Bow

Onion - turnip

leek

Onion

• Wild onion, wild garlic, bear onion, wild garlic, flask - he has many names. This onion family grows everywhere from Europe to the Far East; it can even be found in the tundra zone. Many people grow wild onions in their summer cottage, but, as a rule, they are more often collected wild. Ramson has a mixture of onion and garlic flavors. The plant is rich in ascorbic acid, it increases appetite, increases the secretion of digestive glands, and enhances intestinal motor function.

• Shallot . It is very similar to green onions. Shallot bulbs are small and elongated, but have a more pronounced taste and smell compared to regular onions.

Chives . Soon. Chives. This species is good because it can be eaten in early spring, as soon as the snow melts. It can also be used for decorative purposes until late autumn. Chives are an irreplaceable source of spring vitamins. The bulbs of this type are very small, collected in 15-20 pieces. Flowers range from pale pink to light purple

Slime Bow . A characteristic feature of this type of onion is that the leaves are thin and flat, quite fragile; when broken, a slimy juice is released, hence the name of this species. The taste of the slime onion is mildly pungent. The bulbs are very small, only 1.5-2 cm.

• Red onion. This type of onion is not only good for food, it is often added as a decoration to dishes. In general, this type is mainly used for salad purposes. Red onions are sometimes called purple onions. The skin of this species is purple-red, the flesh is white with a hint of red. These onions are typically medium to large in size, with a flat to flat-round head and a sweetish taste.

Growing, planting, caring, harvesting and storing onions .

Onions can be cultivated in several ways:

Sowing seeds directly into the ground

Growing seedlings and planting them in the ground

Growing onion sets, which are planted in the second year to produce green onions (feathers) or early onions.

"The use of onions in medicine"

• For colds, especially coughs and sore throats
• For rheumatism and to reduce itching from rashes
• For calluses , cures boils
• For treatment of stomatitis
• Helps reduce content blood cholesterol
• Brings relief and for insect bites
• For swelling, rheumatic pain, ringworm, hair loss and dandruff

There are several simple ways to grow green onions on your windowsill at home in winter.

I used this method: I planted onions in boxes with soil prepared in the fall, placed the box on the windowsill (it is recommended to grow green onions on the south-east, south-west or south windows), watered with warm water, and after a few days I got a harvest of green onions.

Conclusion:

While working on this project, I learned the history of onions, types of onions. I was convinced that it is not for nothing that in Rus' they have long said about onions that they help against seven ailments. I was able to identify the widespread use of onions in medicine, cosmetology, and cooking. Now I myself know several useful onion infusions. And most importantly, I managed to grow onions at home. It’s interesting that an ordinary vegetable holds so many secrets. Now I want to tell my classmates about him

2013 MY FAVORITE BOOK Completed by a 1st grade student of the Redkinsky secondary school Municipal Budgetary Educational Institution Sergey Tsygvintsev

All people love to read fairy tales in childhood. There are also adults who secretly read colorful children's books from their children, but fairy tales are still a favorite pastime for children. Every child has his own favorite book and his favorite fairy-tale character. My favorite book is called “The Magical World of Fairy Tales.” It contains famous Russian folk tales and tales of foreign writers. They teach goodness, justice, courage.

My favorite writer is Charles Perrault. I recently read his fairy tale “Puss in Boots”.

Puss in Boots is one of my favorite fairy tales. I personally, for example, liked such a resourceful and talented cat. Which, moreover, makes its owner rich. I think each of us would like to have such a personal cat. Well, while he is gone, all that remains is to dream and believe in miracles, which sometimes occur in real life.

Even if the fairy tale is fiction and a lie, But here you will read between the lines, That you will confidently enter life only through the school threshold. A transparent ray of sunshine will pave your path in the world, And life is based on what, You will understand when you wake up at dawn!

Thank you for your attention!

Design and research work on the topic: “Why should you brush your teeth?” Completed by: 1st grade student of the MBOU Redkinsky secondary school Sergey Tsygvintsev 2013

Purpose of work: Understand why you need to brush your teeth and how toothpaste affects tooth enamel. Object of study: oral cavity, toothpaste. Subject of the study: the effect of “Drakosha” toothpaste on tooth enamel. Objectives: - Study the structure and composition of the tooth - Find out the types of teeth - Rules for brushing teeth and oral care products. - Conduct a survey and experiment. - Draw conclusions. Research methods: - collect information about toothpastes - conduct an experiment.

Statement of the problem One day the day came to an end. I was tired, but my mother insisted that I needed to brush my teeth. I thought: Why do you need to brush your teeth? Why is the toothpaste sold in the store different and how does the paste affect tooth enamel? I decided to find the answers to these questions myself.

The concept of a tooth A tooth is a bone formation located in the human oral cavity that performs the functions of grasping, holding food, and mechanically processing it - chewing. Week 1: I decided to read books and articles on the Internet on my topic to understand what teeth are like. And here's what I found out:

Composition of the tooth The root of the tooth (3) is located in a special recess in the jaw. The main function of the root is to attach the tooth to the jaw. The neck of the tooth (2) separates the root from the crown. The neck begins where the enamel layer ends. The crown of the tooth (1) normally protrudes above the edge of the gum. The crown is covered with enamel, the hardest, chewing part of the tooth. In the crown of the tooth there is a cavity of the tooth, which passes into the dental canal.

Types of Teeth Human teeth are not all the same in shape and function. In the front part of the mouth there are incisors - teeth with a cutting edge that perform the function of biting food. On the sides of the incisors are fangs - cone-shaped teeth designed for tearing off pieces of food. Next are the small molars (premolars) and the large molars (molars). These teeth are larger. They have a chewing surface and have more than one root. On the chewing surface of such teeth there are depressions called fissures. These teeth crush and grind food.

Rules for brushing teeth The toothbrush should move along the tooth from top to bottom Don’t forget to clean the inside of the tooth Be sure to clean the space between the teeth Gently brush the back (molars) teeth.

Dental care products Modern dental and oral care products, according to their purpose, can be systematized into groups presented in the diagram. Means for mechanical cleaning of teeth include: - toothbrushes; - interdental products: toothpicks, dental floss, tapes, brushes; - toothpastes, powders; - dental elixirs (rinses).

Survey results As a result of the survey, I found out that 90% (18 out of 20 people) of my classmates regularly brush their teeth 2 times a day (morning and evening). The survey showed that the children in our class use various toothpastes, but they all belong to the type of children's toothpastes. Colgate Hare paste is used by 20% (4 people) of students, preference for Smeshariki paste is given by 10% (2 people), New Pearl and Moe Solnyshko paste was chosen by 15% (3 people) of respondents. The least popular paste in the class is “Aquafresh”. It is used by 1 person in the class (2%). The majority of my classmates, according to the survey - 25% (5 people), use Drakosha toothpaste.

Week 3: Conducting an experiment After studying theoretical information and conducting a survey in class, I decided to conduct an experiment and find out in practice how “Drakosha” toothpaste affects tooth enamel and protects it from harmful acids. For the experiment, I took: 2 chicken eggs 2 containers Acetic acid (9%) Citric acid (9%) Drakosha toothpaste Toothbrush

Experiment 1) Separate the eggs in half with an adhesive plaster 2) Apply toothpaste to one of the egg halves 3) Place one egg in acetic acid and the other in citric acid.

Observations I observed that, under the influence of acids, bubbles appeared on the untreated halves of the shell. As a result, after 5-6 hours the untreated halves of the eggs became soft, while those treated with Drakosha toothpaste remained hard. Based on this, I concluded that acids destroy tooth enamel. Toothpaste containing fluoride and calcium strengthens tooth enamel.

Conclusions and conclusions After conducting research, I realized several rules that must be followed: 1) You need to brush your teeth with a toothbrush and toothpaste every day: in the morning after breakfast and in the evening before bed 2) The toothbrush needs to be rinsed thoroughly. Do not store it in a closed case. The brush needs to be changed periodically. 3) You need to use special children's toothpastes. And choose the one that suits you best. 4) Don't forget to visit your dentist twice a year, even if your teeth don't hurt. 5) After each meal, you should rinse your mouth with water. If you don’t have this opportunity, use chewing gum, but not for long! If you follow these simple rules for oral care, your smile will always be snow-white and your teeth healthy. Despite the fact that I have learned a lot about how to properly and why you need to brush your teeth and what toothpastes to use, my research does not end there. In the future, I would like to look at the question of why do teeth hurt? What is caries and how to fight it?

We brush, brush our teeth and live happily. And for those who don’t brush them, We sing a song: - Hey, don’t yawn, Don’t forget about your teeth, From bottom to top, from top to bottom Don’t be lazy about brushing your teeth.

Design and research work on the topic: “Why is snow white?” 2012 Completed by: 1st grade student of the MBOU Redkinsky secondary school Tsygvintsev Sergey

White fluffy snow swirls in the air and quietly falls to the ground and lies down. And in the morning the Field turned white with snow, as if everything had been covered with a shroud.

Statement of the problem Winter has come. It became cold outside. One morning I woke up and looked out the window. I saw that everything around me: the ground, trees, roofs of houses, became white. It was the first snow. I wondered: Why is snow always white?

how I conducted the research 1 day I read books on the topic. I decided to test my guess that the white color of snow is associated with the reflection of light.

I learned from books: -each snowflake is a small piece of ice -snowflakes lie differently -snowflakes reflect light in different directions

How I conducted the experiments. Day 2 Experiment 1. I took a glass, a piece of polyethylene, and scissors. The whole piece of polyethylene is transparent.

Then I cut it into small pieces and put it in a glass. Each piece is a model of a snowflake. Result: “Snow” in a white glass.

Experiment 2. I poured water into a glass and put it in the freezer. After some time, the water froze and turned into transparent ice.

Broke it into small pieces. It turned white.

Conclusion. From experiments I understood: polyethylene and a piece of ice are transparent. Light passes through them without being reflected. Pieces of polyethylene and ice lie differently and reflect light in different directions. Conclusion. Snow is white because each snowflake reflects light in different directions. Light, as scientists say, “scatters.” This is how the color turns out to be white.

Completed by: 3rd grade student of the Redkinsky secondary school Daria Maltseva Project work “Chocolate: benefit or harm”

Purpose of the study: to study the question of the positive and negative effects of chocolate on the human body. Objectives: 1. To get acquainted with the history of chocolate. 2. Collect information about the dangers and benefits of chocolate. 3. Establish the effect of chocolate on human health. 4. Study the composition of chocolate.

The history of chocolate began a long time ago, more than 500 years ago. Christopher Columbus brought cocoa beans to King Ferdinand from his expedition to the New World.

Chocolate comes in different varieties; it is made from chocolate mass with the addition of milk. They produce chocolate in the form of bars, bars and other shapes with various fillings: nut, cream, milk and butter.

Benefit. 1. Chocolate gives energy to a person. 2. Rich in sugar and fat. 3. Contains potassium and magnesium And chocolate is also good for the heart; doctors have found that cocoa beans contain substances that have a beneficial effect on the cardiovascular system. There is such a belief that chocolate is harmful to teeth. Chocolate is not harmful to teeth because cocoa prevents the destruction of tooth enamel.

1. There are several chemicals in chocolate that make it addictive, such as caffeine. 2. Sweets can also cause stomach pain, heartburn and nausea. Harm.

Conclusion. Moderate consumption of chocolate has a beneficial effect on humans. Chocolate contains beneficial substances that have a positive effect on the functioning of the body, but excess of these substances can harm the body.

REDKINSKAYA secondary school Research work. “What do our names mean?” Komissarova Tatyana 3rd grade Tavlikhanova Natalya Nikolaevna G. Bor, 2015

Goal: to understand the mystery of the name and how it affects a person’s fate. Objectives: -to study the history of the appearance of my name; -learn the meanings of your classmates’ names; -learn to implement the results obtained.

Riddle - what belongs only to you, but others use it more often? This is a mystery about the name. A name is an integral part of personality. To touch a name means to touch a person. A person’s name carries a wealth of information and provides answers to numerous questions. In which profession are the natural inclinations of a future citizen most fully revealed? How will the relationship be with the family? How will he raise his children?

The name reveals a person’s character and can influence a person’s fate and choice of future profession. Since ancient times, humanity has been sensitive to the name. As a rule, it testified to the purpose of the newborn, and by giving a name, they counted on the patronage and protection of God.

The source of many names that are still used today is the Bible, in which each name means something to a person. I learned that the names of my classmates mean the following: Angelina - angelic, Tatyana - founder, Valentin - healthy, Maxim - greatest, David - beloved, Augustine - blessed, Sergei - obedient, Anna - mistress, Anastasia - resurrecting, Mikhail - who knows God, Eugene is noble, Vladimir is to rule the world, Christina is a Christian, Daria is strong, Vasilisa is a queen, Kira is a mistress, Nikita is a winner, Alexander is a protector of people.

THE SECRET OF THE NAME TATYANA. What's in my name? My name is Tatyana. Mom and dad named me after the calendar, because I was born in January, when Tatyana’s name day is January 25. The planet Mars. Colors - yellow-green, sky blue, symbolizing the soul, red. The name Tatyana, of Greek origin, means “organizer.” The patroness of all Tatianas is Tatiana, who lived in the 3rd century AD. Tatiana dedicated her life to teaching Christianity. Executed during the persecution of faith. In Russia, Tatiana is considered the patroness of students, because on January 25, 1755, a decree was signed on the founding of Moscow University, and the university church received the name of the holy martyr Tatiana.

Church of the Great Martyr Tatiana in Moscow.

MEANING OF THE NAME TATYANA. From a very early age, Tatyana knows what she wants, does not tolerate objections, has an excellent memory, is charming, loves to receive guests, is successful in various fields, but gives preference to creative professions. In the natural world, its symbols are blueberries and lynx, and the name Tatyana corresponds to the number 3, which indicates talent, the world of art.

I learned that many famous people have the same name: Tatyana Samoilova - actress Tatyana Peltzer - actress Tatyana Tarasova - figure skating coach Tatyana Gorbunova - gymnast Tatyana Navka - figure skater Tatyana Plokhikh - the smallest woman in Russia height-81cm weight 11kg In our The school has 2 teachers named Tatyana.

After doing all this research, I learned a lot of interesting things, and now I know everything about my name, I realized that a person’s fate is closely connected with his name. I learned to find interesting information in different sources.

SOURCES. 1) Orthodox church calendar. 2) How to choose a name for your child B. Heeger. 3) Internet.

I was interested in the question: What are the most common dental diseases? How to cure them? I set myself the goal of finding answers to these questions. Purpose of the work: 1) learn about the most common dental diseases; 2) study various ways to treat toothache. Object of study: oral cavity, onion peel tincture. Subject of research: treatment of caries with onion peel tincture. Objectives: - To study the concept of toothache. - Find out what dentistry is. - Learn about dental diseases such as caries, pulpitis, periodontitis and methods of their treatment. - Conduct a survey and experiment on the treatment of toothache. - Draw conclusions. Research methods: - collect information about dental diseases - conduct an experiment.

Toothache, like any other pain, is a protective function of the body, a kind of signal that not all is well with the teeth. Week 1: I decided to read books and articles on the Internet on my topic to understand what toothache is. And this is what I learned: Dentistry is a medical discipline that studies the organs of the oral cavity, their physiological and pathological conditions, and also deals with the prevention and treatment of diseases of these organs.

CARIES Dental caries is one of the most common diseases encountered in dental practice. 95% of the population has dental caries in one form or another. The main reasons for the occurrence and development of dental caries: poor oral hygiene (insufficient dental care and irregular brushing), irregular visits to the dentist, weak body immunity, poor nutrition (lack of vitamins, an abundance of foods containing sugar, lack of raw vegetables and fruits in the diet) low content calcium, fluorine and phosphorus in drinking water - the body's hereditary predisposition to caries. Depending on the stage of the disease, the following types of caries are distinguished: initial dental caries, superficial dental caries, medium dental caries, deep dental caries TREATMENT AND PREVENTION Hygienic teeth cleaning Balanced diet Regular visits to the dentist Tartar cleaning

PULPTIT Pulpitis is a dental disease associated with inflammation of the pulp (soft tissues of the tooth, including the dental nerve), which usually occurs as a result of advanced caries. The main causes of pulpitis are microbes and their metabolic products that penetrate to the nerve of the tooth from the carious cavity; various mechanical injuries to the tooth, as a result of which a significant part of the tooth breaks off or chips; exposure to temperature or chemical irritants often tooth pulpitis is a complication of caries, and can also be a consequence of incorrect actions by the doctor (poor quality fillings, exposure to chemicals).

Treatment and prevention of pulpitis TREATMENT AND PREVENTION Start treatment at the dentist earlier Timely treatment of caries Monitor oral hygiene TREATMENT AND PREVENTION

Periodontitis Periodontitis is an inflammation of the periodontium (dense connective tissues that hold the root of the tooth in its cell). Symptoms of periodontitis The first sign of periodontitis is bleeding gums when brushing your teeth and persistent bad breath. Unpleasant sensations can occur when eating food; the reaction of “ache in the gums” can be especially acute with cold or hot food. The symptoms distinguish between acute and chronic periodontitis. TREATMENT AND PREVENTION Maintaining oral hygiene Timely dental plaque removal Paying attention to your diet

Week 2: In-Class Research

Week 3: Conducting an experiment After studying theoretical information and conducting a survey in class, I decided to conduct an experiment and learn in practice how onion peel tincture helps in the treatment of caries. To prepare we need: Onion peels (3 teaspoons) Water (0.5 liters) Gauze or strainer for straining the broth Small saucepan

Experiment The sequence of my actions: Take half a liter of water and boil it in a kettle. After the water has boiled, take a pan, pour onion feathers into it and pour boiling water over it.

Experiment 3) After this, bring the resulting mixture to a boil. 4) Then strain the solution through cheesecloth and let it brew for eight hours. 5) The drug is ready for use.

Observations For a whole month, 2 times a day (morning and evening), I rinsed my teeth with a decoction of onion peels. After that, I went to see the dentist, and his answer about the condition of my oral cavity was very pleasing: on those teeth where there was initial caries, it went away. on those where it was deep, it remained unchanged because, according to the dentist, deep caries cannot be cured without the intervention of a doctor. CONCLUSIONS After conducting research, I realized several rules that must be followed: It is always better to prevent the occurrence of diseases than to deal with its consequences, this is a truism. It’s trivial, simple, and most effective - brush your teeth regularly. Chew sugarless gum. Avoid eating anything sticky or sweet. Visit your dentist regularly. In my next work I will consider the topic of implants because nowadays healthy teeth and a beautiful smile are an integral attribute of a person’s well-being and success in society.

Research activity of students is one of the priorities of modern education.

Therefore, it is important to create psychological and pedagogical conditions in elementary school to fulfill the age-related need for search activity.

Without the skills of research educational activities, it is difficult for students to master the program offered by the basic and high schools.

The specificity of research work in primary school is the systematic, guiding, stimulating, corrective role of the teacher; involving parents in participating in their child’s school activities.

The teacher must be able to see and help select the most interesting and practically significant topics.

• Research (literally "following from within") in its broadest sense is the search for new knowledge or systematic investigation to establish facts. In a narrower sense, research is the scientific method of studying something.
• Choosing a topic is a very difficult and responsible stage of research.
• The next and very important stage in working on a project and research is determining the relevance and practical significance of the work.

• Any goal must have five main features:
• completeness of content;
• temporary certainty;
• reality (correspondence to possibilities);
• motivation (compliance with the motives of the subject of activity);
• operational definition of the expected result.

• The hypothesis has certain requirements:
• it must contain an assumption;
• it must be verifiable and confirmed using methods;
• it must be logically consistent;
• it must be really refutable or provable.
• To test a hypothesis means to check the consequences that logically follow from it.

• Having set a goal and defined tasks, it is necessary to select ways and methods of conducting further research.
• Method is a way to achieve the goal of research; its decisive role in the success of a particular research work is obvious. Basic research methods: observation, experiment, modeling, questioning, interviewing, analysis and synthesis, comparison, generalization, classification, definitions of concepts.

At the planning stage of a work study, it is necessary to draw up a plan, which is a more detailed statement of issues on which all the collected factual material will be systematized in the future.

The result of the research work of junior schoolchildren is preparation for the defense and the defense itself. The collected materials can be presented in the form of a model made of different materials with a description of the action of the object it represents. Children should be helped to choose how to present their results based on the topic and their own capabilities.
