Atoms of science. Chemical compounds, electric current, simple mechanisms

Cognition of the world plays an important role in the development of the child. But taking the first steps towards science is not at all easy. In this book, schoolchildren Sasha, Zhenya and Fedya will help young readers understand the basics of mechanics, chemistry and electricity. Science surrounds us everywhere, hides in the most ordinary things! Why, for example, is a bicycle rust? Where does the electricity come from in the battery? How do swings work? From the answers to these and other seemingly simplet questions, an understanding of complex processes and phenomena is formed in the same way as molecules form from atoms. Therefore, our book is called the atoms of science.
