Chemistry - course 7250 rub. from Sciencely. Smart Moscow, training 1 month, Date: November 29, 2023.

5th year student of the Department of Enzymology, Faculty of Chemistry, Moscow State University named after M.V. Lomonosov. Maria's scientific activity is related to the search for new and the study of already known enzyme inhibitors that contribute to a more effective fight against cancer. By the way, the enzymes that Maria also works with are bright representatives of the nanoworld. For several years I managed to work at the Polytechnic Museum as a guide and as an employee of the biohacking laboratory, and now I give all my love for science to the participants of our circles.

Lera studies at the Faculty of Chemistry of Moscow State University and develops methods for detecting brain cancer cells and targeting antitumor therapy using aptamers (small molecules consisting of the same “pieces” as ours your DNA). In classes with children, she tries to show the connection between biology and chemistry and the scope for exciting research in these areas of science.

Sasha is a final year student at the Faculty of Chemistry at Moscow State University, and at the same time works in the laboratory of biodegradable polymers, where it receives new materials that can replace polyethylene or polypropylene for packaging various products. Such technologies are also used in medicine, making it possible to package a drug and deliver it precisely to target cells or organs. Sasha loves to tell children about science, but does it without unnecessary simplifications and misconceptions, because even a young scientist must obtain a base on the basis of which he can further build his scientific research and study the huge and interesting world around us world.

LESSON 1. SIGNS OF CHEMICAL REACTIONS

We get acquainted with chemical equipment and safety precautions - why gloves are needed, how to sniff substances and how not to. Let's discuss what chemists do in general, what is the difference between physical and chemical phenomena. Afterwards, we will begin experiments and understand the signs of chemical reactions. To do this, we will carry out reactions with the formation of a precipitate, a change in color, and the release of gas and heat!

LESSON 2. ATOMIC STRUCTURE

Let's try to understand how the atom works and why chemical reactions are possible in our Universe. Let's get acquainted with the periodic table, understand by what principles the elements are arranged and what the significance of serial numbers is. And to confirm the theory with practice, we will isolate pure tin from tin chloride.

LESSON 3. INDICATORS, ACIDS AND BASES

Let's continue to structure our knowledge about ions, understand the classification of inorganic substances and what makes an acid an acid. We will conduct experiments with indicators, determine pH and check the acidity of all representatives of household chemicals.

LESSON 4. CHEMICAL SALTS

Using coloring pigments as an example, we will understand the concepts of solubility and insolubility of salts. Let's discuss how salts are structured, what can be built from ions, and how signs of chemical reactions are used for the qualitative determination of inorganic compounds. We will carry out qualitative reactions to copper ions, and then identify unknown substances using the knowledge gained. At the same time, we will make several paints based on synthesized salts.

LESSON 5. METALS

Let's get acquainted with metals and study their physical and chemical properties. Let's carry out reactions between metals and acids. And we will reinvent the activity series of metals. We will consolidate our knowledge with the help of a quiz on the covered topic.

LESSON 6. METHODS OF ANALYSIS IN CHEMISTRY

Let's master quantitative analysis in chemistry. Applying the knowledge from the third lesson, we will try to understand what titration is and titrate an acid with an alkali. At the end of the lesson, we will review the topics covered and consolidate the knowledge gained.

LESSON 7. INTRODUCTION TO ORGANIC CHEMISTRY

Let's study the nature of carbon bonds and find out that in fact, in addition to inorganic compounds, there is a large group of organic substances. Let's find out what common properties they have, record the knowledge by carrying out five qualitative reactions with the main classes of organic substances - with carboxylic acids, alcohols, carbohydrates and even cyclic hydrocarbons we'll capture it.

LESSON 8. PROTEINS

Let's learn the difference between polymers and monomers using the example of proteins. Let's talk about their complex structure and meaning in our lives. Using chemical methods we can distinguish between types of proteins. We will carry out qualitative reactions on them and sweeteners based on them, and then we will denature the egg white in different ways.

LESSON 9. CARBOHYDRATES

Let's start getting acquainted with carbohydrates and carry out qualitative reactions to various structural groups. Let's find out what wood and starch have in common. Let's dive into the world of biopolymers - let's check whether starch and cellulose really consist of the same substance, although they exhibit different properties. To do this, we will obtain Benedict’s reagent, and then, with its help, we will evaluate the quality of honey.

LESSON 10. VITAMINS

Let's talk about chemistry and our health. Let's understand the types of vitamins, the importance of the correct dosage, and why you need to consume vitamin C in much larger quantities than others. We will carry out qualitative reactions to vitamins C and E and restore riboflavin (vitamin B2).

LESSON 11. POLYMERS

Let's continue our study of organic compounds, focusing in more detail on synthetic polymeric substances. We'll look at ways to produce different plastics, and also make our own polymer and even artificial silk. Let's understand that chemistry makes our lives more comfortable and easier.

LESSON 12. FINAL QUIZ

Let's summarize all the knowledge gained in class. We will conduct a mini-exam where we will sharpen the acquired skills in the field of chemistry.

CLASSES 13-24. SYSTEM OF CHEMICAL ELEMENTS
Let's get acquainted with the periodic system of chemical elements and its individual components. Let's learn to predict the properties of elements simply by their location in the table. We will learn about some elements, their application in life, and where they can be obtained/seen. Each lesson will reveal the characteristic properties of one of the groups of the table.
