Rebuses are drawings, images or symbols that need to be solved or deciphered. Rebuses encrypt individual words, sayings, proverbs, excerpts from works, etc. To solve the rebus, you need to determine the meanings of the given pictures or symbols and write them down one after the other without spaces or punctuation marks. After that, the resulting series of letters is divided according to their meaning into individual words, which make up a phrase. When composing puzzles, they use certain techniques for encrypting text or individual words. For example, the picture shows a house, and to the left of it there is a comma. This means that one initial letter of the word HOUSE is discarded, and the remaining part is written OM.

The game involves 2 teams of players (grades 8–9). A week before the game, teams are tasked with choosing a captain, coming up with a name for their team and emblems for the players, and making signs with the team name. 3 days before the game, both teams become familiar with the rules of solving puzzles and practice solving charades, anagrams, and metagrams.
To play the game you need 2 presenters. The 1st presenter must work with the slides, read the conditions of the tasks chosen by the players. The 2nd leader must lead the entire game. In addition, you need 2 people who must demonstrate entertaining experiments and tricks.
Anyone from grades 8–9, 11 can be invited as spectators to the event.
Tricks are demonstrated after “Anagrams 30” and “Charades 20”.
After answering “Rebuses 25” it is shown entertaining experience“Fireproof scarf.”
After answering “Metagrams 50”, the entertaining “Volcano” experiment is demonstrated.
Goals: to develop educational, cognitive and information and communication competencies of students, cognitive interest in the subject of chemistry; develop organization, responsibility, and ability to work in a group.
Equipment: electronic presentation “Kaleidoscope of chemical mysteries”, plates with team names, emblems for players, a stage table, a heating device, paper with the inscription “Good luck” (the inscription was made the day before with dilute sulfuric acid using a glass rod), a crystallizer with water, a crystallizer with ethyl alcohol, handkerchief, glass rod, ammonium dichromate (crystals), for tricks: the periodic table of chemical elements, a poster with the signs of the elements Na, O, H. The teams were given on the tables: the periodic table, a printed playing field, sheets of paper for each player, pens.
Presenter 1: Dear friends! We are starting the game “Kaleidoscope of Chemical Riddles”. Today we have 2 teams in the game. Let's welcome our players! (Introduction to teams and captains.)
Now let's get acquainted with the rules of the game. Before us is the playing field. It consists of 5 nominations: “Simply riddles”, “Anagrams”, “Rebuses”, “Charades”, “Metagrams”.
Presenter 2: Each nomination is represented by 5 tasks of varying difficulty. The difficulty of a task can be judged by its code number: the larger the number, the more difficult the task and, accordingly, the more points the team will earn if they answer correctly. Teams choose a task in turn, naming the nomination and the task code number (sum of points for the correct answer), for example, “Rebuses 10”. You are given 1 minute to think about each task. If the team can answer before this time, then the captain gives a signal and the team answers ahead of schedule. An early answer, if correct, will earn each team member a surprise prize, which players will receive at the end of the game. If the early answer is incorrect, the right to answer the riddle question passes to the opposing team. The teams have paper playing fields on their tables. Please mark those tasks that have already been selected so that there are no repetitions.
We will determine which team will choose first by drawing lots. (captains participate in the draw).
Presenter 1: Now let's get acquainted with the nominations. The easiest nominations are “Simply riddles” and “Rebuses”. The nominations “Anagrams”, “Charades”, “Metagrams” are presented with more complex tasks, but if successful they will bring the teams an impressive amount of points.
The “Simply Riddles” category presents 5 simple chemical riddles in a classic form. They talk about chemical elements and simple substances. In the “Rebuses” category, players will be offered images that hide the names of chemical elements.
Let us remind you that Anagrams are riddles whose answers consist of the same letters.. For example, the words flask and glass can form an anagram. Having guessed one word in the riddle, you need to rearrange the letters so that you get a new word. You must include both words in your answer.
Presenter 2: In the nomination “Charades” you will hear riddles, the answers to which are solved in parts. For example, two words MOUSE and YAK, when combined with each other, form the whole word ARSENIC. Metagrams are riddles in which different words consisting of the same number of letters are encrypted. Having solved one of the words of the metagram, you need to replace one or more letters in it so that you get a new word according to the meaning of the riddle.
Dear players! Note! If you see a “Smile” emoticon on the question sector, then after completing the task you will be shown a trick. Tasks are marked with a red cloud on the playing field, after which you will be shown an entertaining experience. And our tenth graders Ilya Konstantinov and Fedor Samarkin will do this for you (bow to the audience)
Konstantinov: Friends! Yesterday I found an unusual envelope in our school's mailbox addressed to our teams. There is no return address on it. But the most amazing thing is that the envelope contains a blank sheet of paper!
Samarkin: Nothing special! It's just a letter written with chemical ink. To read such a letter, it needs to be heated. Look! (Demonstration of the “Secret Letter” experiment.) The inscription “Good luck” appeared on the sheet. I join the unknown letter writer in wishing all the players good luck in today's game.

Presenter: (After anagrams 30 ) Dear friends! Now before your eyes Ilya Konstantinov and Fedor Samarkin ( come out) will conduct a session of transmitting thoughts at a distance through words.
Konstantinov: To conduct a session, you need one person from the audience, preferably one who can count well orally. Does anybody want?
(Meeting an eighth-grader, Samarkin is blindfolded)
Konstantinov to an eighth grader: Think of some chemical element and silently show it with a pointer in the table.
Konstantinov to Fedor: Fedor!
(Approaches Samarkin, waves his hands above his head). Concentrate your thoughts on receiving the telepathic signal.
Konstantinov to the eighth grader: find the serial number of the element in the table, but do not say the numbers out loud.
(Pause)
Multiply it by two
(Pause),
add 5 to the product
(Pause).
Multiply the resulting amount by 5
(Pause).
Now say the final result loudly 2 times
(Unties Samarkin’s eyes, Samarkin approaches the table)
Samarkin: an element was conceived...(names the element and shows it in the table) To determine the intended element, the last digit is discarded from the number named by the viewer, and then subtracts 2 from the remaining number. Having calculated the serial number, he finds the desired element in the table and shows it to the audience with a pointer
Presenter 1. (After charades 20) A poster with signs of chemical elements is placed on the board: H, Na, O.
Konstantinov: Dear friends! Now you will see that a telepathic signal can be transmitted not only through a word, but also through the warmth of a hand (blindfolds Samarkin’s eyes).
Anyone want to test Fedor's telepathic abilities?
(Meet the audience)
Go to the poster and silently point to any of the three chemical elements with your pointer. (Unties Samarkin's eyes)
Samarkin : touches various signs on the poster with his hands, as if trying to feel something, and at this time listens carefully to Konstantinov. Focus Code: ABOUT - what element? Na- well, what was planned? N – now guess!
Konstantinov: (says the code for Samarkin depending on the situation)
O - what element
Na – well, what was planned?
N - now guess!
Samarkin: ( The code determines the intended element. He holds his hand on it longer and calls it out loud.)
Heat comes from this element... It was conceived... ( Names the element)
The final. Winner's reward ceremony.
