And two ohms each.
Contest "Experts in Mathematics"
O.V. :
Task 1.
Archaeologists of the distant future will someday unearth two petrified diaries with a large number of twos. In Misha's diary they will find 234 deuces, and in Tolin 2/3 of the number of these deuces. How many deuces will be found in 2 diaries?
- 234*2/3 = 156 - "2" in Tolin's diary.
- 156+234 = 390 - total
Task 2. Write the answer and solution on a piece of paper.
Sheets with solved tasks are transferred to the jury.
- The owner of the sewing workshop hired 20 girls and placed them in 8 rooms.
- In the evenings, she made sure there were 7 girls in the rooms on each side of the house.
- 4 friends came to visit the girls. All 24 girls were placed so that the hostess again counted 7 girls in the rooms on each side of the house. How are the girls accommodated in the rooms with their friends?
20 girls
24 girls
Task 3. (for reserve)
Somehow early in the morning
The birds were swimming in the pond.
snow white swans
Three times more than geese
There were eight pairs of ducks -
Twice as many as loons.
How many birds were there
If we are still given
That all ducks and geese
As many as swans! (swans - 24, ducks - 16, geese - 8, loons - 8).
Solution.
- geese - x, swans - s x, ducks - 16, loons - 8
- x + 16 \u003d 3 x, - 2x \u003d - 16, X \u003d 8
N.V. : The next competition is called " Black box".
You must find out what is in the black box.
Black box
O.V. : What lies in the black box was invented in ancient Greece.
- IN ancient greece the ability to use this subject was considered the height of perfection, and the ability to solve problems with its help was a sign of a great mind.
- This item is indispensable in architecture and construction.
- For many hundreds of years, the design of this item has not changed.
- Nowadays, any student can use it.
N.V. : It is used in systems and mechanisms for heating and cooling.
- used to reduce friction.
- With all three states of aggregation of this substance, you often meet.
- This substance is called the juice of life on Earth.
O.V. Question: what is in the black box? (Compass, water). Jury word.
Contest "Connoisseurs of logic"
N.V. : Problem with matches.
Match crayfish creeps up, Move 3 matches so that it crawls down.
O.V. : We ask the jury to check the correctness of the assignment
N.V. : And, finally, let's figure out who the captain is, because there is a competition of captains ahead.
O.V.: The captain is the head and senior coach of the team. Before the tournament, he works with the team like an ox, and during the game he fights with the jury like a lion. Captains competition
N.V. Captains, please come to me. You are invited to solve a problem about a turnip.
Answer and answer in writing.
Which of the captains will be ready to answer, raise your hand so that the jury can see that you are the first.
Task. The grandfather, holding the turnip, develops a traction force up to 600 N, the grandmother up to 100 N, the granddaughter up to 50 N, the Bug up to 30 N, the cat up to 10 N and the mouse up to 2 N. What is the resultant of all these forces directed along one straight line and in the same direction?
Would this whole company cope with a turnip without a mouse if the forces holding the turnip in the ground are 791 N?
(Answer: The module of the resultant force, equal to the sum of the modules of forces, will be equal to 792 N. The contribution of a muscular mouse to this mighty impulse is 2 N, so things will not work without mouse Newtons!
O.V. : While the captains are solving the problem, there is a competition for the teams Stories with hints
You must guess the word. We give you hints, with each hint you lose one point. Maximum amount points that you can bring to your team's piggy bank 5 points.

Self-analysis of the extra-curricular event "Erudite Tournament"
The event was held in the 8th grade, the students of the class are not strong in mathematics and physics, and the main purpose of this event was to change their minds in studying these subjects, to show that both mathematics and physics can be interesting.
The main goals we set are:
- On the basis of a competitive game, develop ingenuity, ingenuity and activity of students;
- To develop a cognitive interest in the educational material, the individual abilities of students, to develop logical thinking;
- Raise the prestige of smart, but not always popular students in the class (since there are negative leaders in the class who “pull” everyone else down.
- Increase motivation to study
- Develop communication skills through group work.
The form of the event is an intellectual and entertaining game.
The event was held using a presentation for clarity, for those children who do not perceive the text on the presentation slides very well, all tasks were duplicated on cards.
Forms of work at the event - frontal, group, individual.
Efficiency. The guys worked - actively, they showed that they can work in a team - they know how.
Tasks for logical thinking (cancer, black box) were handled by _________
(Fine?)_____.
During the game, the guys listened first of all to the "strong" students.
Shortcomings discovered during the event _____________, causes and solutions _____________________________.
We think that this extracurricular activity goals achieved (?).
