"The best expert in chemistry"

Before the start of the intellectual game, the participants got acquainted with the book exhibition "Wise Sciences without edification and boredom".
Divided into two teams - "Acid" and "Molecules", the participants were introduced to the rules of the brain ring.
As a warm-up, the participants were offered tasks for chemical reactions, which they were able to easily cope with. And also, using the words homonyms, the participants had to determine the meaning of chemical and biological terms. As part of the intellectual game, the participants answered questions about the history of chemistry and the use of various chemical elements in the world.
Next, the participants had to guess the contents of the Black Box by answering the question. Answering leading questions, the students were able to find out the answer to what chemical elements were hidden in the Black Box. It was suggested to guess riddles and "Funny shifters" about chemical elements known to them, to take the quiz "Do you know the biography of D.I. Mendeleev".
