But since 1950, they began to detect its ever-increasing concentration in the tissues of animals, fish, birds, and humans. The number of insects not susceptible to it has increased dramatically. So it turned out to be one of the first global pollutants of the Earth. In 1970, the use of the substance was banned. However, quite recently it turned out that up to 30 percent of impurities are present in the technical substance, which were the reason serious illnesses of people. Name this substance.
2. In one of the lectures, V.V. Dokuchaev told students: “Today I will talk with you about .... I find it difficult to name the subject of our conversation - it’s so good!

7th competition.
Captains - the music sounds, the captains come out.
Competition - readers.
Here is ecology - a fashionable word,
Previously, nature did not know this,
Banks, bottles were not thrown into the bushes,
Waste and oil were not dumped into the river.
Rats and mice now thrive
Valuable species, alas, disappear,
Who poisons himself with a cigarette
Someone is using drugs.
The Duma is preparing a new Chernobyl for us,
If the public does not stop!
Those who burn waste in landfills
Everyone poisons, both air and water!
Our planet is still alive
But without protection, she will die!
If you want the world to be green
Do not cut down birches and maples!
Home is our planet Earth,
On which forests and fields are beautiful.
We live in this house
We work during the day, we rest at night.
Morning comes, the sun rises
So year after year time goes by.
For me, there is no bad weather in this world.
I want to study the laws of nature.
And I, a man, need beauty,
Like a bird in flight, it needs height.
You force yourself to study the laws,
In order not to treat nature later.
To live by the laws of nature
Of course, you need to know them!
It takes years and years
To feel like a part of it!

Marya Ivanovna: What did you decide to become?

^ The Tale of the Turnip
Grandfather and Grandmother are sitting on chairs on the stage. Behind them, squatting with a large pattern, is a girl - Turnip.
Storyteller (reads): Once upon a time there was an old man and an old woman. One day the old man decided to plant a turnip.
The old man pushes back his chair, and everyone sees the sitting Turnip.
Storyteller: And so that the turnip grows faster and tastes better, I decided to use it
^ Grandfather comes out with a bag of mineral fertilizers.
Storyteller: He took the "magic powder" and began to sprinkle the turnip. I tried, and I overdid it.
Grandfather pours out the whole bag.
Storyteller: Then the grandfather decided how to water the turnip. He still took living water and watered the turnip. The grandfather got tired and decided, in order not to go far, to water the turnip. dead water» . The grandfather watered the turnip well, conscientiously. Has the turnip grown? big big.
^ The turnip gets up.
Storyteller: Grandfather calls grandmother.
Grandfather: Look, grandmother, what a turnip has grown - beautiful, but blush! Gotta try it soon.
Grandmother: Wait, grandfather, I heard that you first need to check the crop, but you really probably overdid it - you watered the turnip with both “living water” and “dead water”, but poured too many powders!
Grandfather: Yes, okay, grandma, you heard a lot of fears.
^ Grandfather bites off a “piece” of a turnip and falls, writhing on a chair, grandmother cries ...
Storyteller: This is what an unreasonable and careless attitude towards nature and the sciences can lead to...

Transfer of the Olympic flame.
Captains are given red flags. At the command "March!" the captains run forward, run around the finishing posts and, returning to the start line, pass the flag to the next player of their team, and themselves stand at the end of the column. The second player, having run around the rack, passes the flag to the third, etc. At the end of the relay, the captain (who is again in front of the column) raises the flag up, the rest of the players spread their arms to the sides (this is the finishing position)
Baba Yaga. Wait! Wait! I want to participate too!

(While the jury is summing up, the participants are performing choreographic ensemble"Fantasy")
Leading. Well, friends, forward again,
The competition awaits again.
Leading. Where, where are they taking me
My natural legs?
Sometimes I don't know myself
Where will I go.
And sometimes they run
Where, where are they taking me?
Ah, legs, legs, you are mine,
Sometimes you pity me.
Competition "Stick underfoot"
The captain runs up to the rack, behind which lies a gymnastic stick, takes it and returns with it to the team. Together with the next player, they carry a stick under the feet of the players (team members jump). The captain remains at the end of the column, and the other player, holding a stick in his hand, runs to the counter, runs around it, returns to the team and, together with the next player, does the same. The relay race ends when the last player gives the stick to the captain and he lifts it up.
Leading. And we again give the floor to the jury. And while it is being prepared, the guys will sing ditties to us.
We are funny guys

We don't shirk.
My darling is a football player,
Well, my basketball player
But mine went to boxing
And they broke his nose.
Oh, girlfriends, on the screen
Day and night gymnastics
Well, isn't that lovely?
Flexibility there and plastic.
I wanted to try-
Went straight to the cellar.
We all play football
Probably the best
And we are naked to the enemy
We kill the right one.
But recently it was funny
We scored a goal ourselves.
Baba Yaga. I also know ditties. I can sleep.
I am beautiful Yaga
I want to please everyone
And the athlete is good too.
Top model graceful
lady real
I'll tell you - it's not nonsense! (dancing)

Guys: Every day you have to practice, not on weekends.
Baba Yaga. Well, that's how I'll fix it
I will play sports
I'm not too lazy to run, jump
Together with you, together with you
Every day, every day.
Leading. Again, everyone got into teams,
And from one station
Move on to another.
New tasks are waiting for you
Show dexterity and attention.
Leading. Look! How funny and clumsy
A fun sack race starts here
The champion's head is outside
And he himself in the bag rushes at full speed!
Competition "Running in bags"
players, standing first, fit into the bags. On a signal, holding the bags with their hands at the waist, they run to a certain place (indicated by a flag, stick or other object). Having run around it, they return to their teams, get out of the bags, pass them on to the next. This continues until all participants run in bags. The team whose players complete the task faster wins.
Leading. How did it happen?
What happened to the person?
He was still small
Suddenly rose to the ceiling
long strides,
wooden legs
He runs himself, runs
And he doesn't tremble with fear.
Competition "Walking on stilts"
Baba Yaga takes big stilts and tries to walk on them. Wow, great!

^ Message from the SOS team to the fans
How many good girls
Gathered around here now
But one thought worries me:
Will they support SOS, my friend?
In the game we will not rest,
And you have to be strong in spirit.
Love cheerleaders restless
Help to survive, win!
Leading: We ask the jury to sum up the results of the first round of the "Greetings" competition.
The results are announced and posted on the scoreboard.
Leading: We begin the second competition: "Decipher the name of the team." The word is given to the Vobla team.
We took "Vobla" in the literal sense,
And not in any dissent,
And we dedicate an ode to this fish,
For us, and for you, and for everyone.
^ Ode to Woble
In those old, distant years
You were the prom queen.
Now you've become an exhibit
You go into oblivion forever.
You were eaten often, a lot, tasty,
With potatoes, with beer, with cabbage,
Saved the common people from hunger,
And now you are almost gone.
So as not to show you in museums,
Like dinosaurs, extinct animals,
For the joy of human existence.
And wobble we all shouted "SOS",
And we really love her.
Save the Remaining - Creation
Mother Nature,
So that she does not go into legends,
She was an idol for people!
And it's good that we called
Team "Vobloy" dear,
Solemnly recognized
Live, real, not a dream.
Leading: The word is given to the "SOS" command.
"SOS" - short - save souls,
Nature has been crying out to everyone for a long time.
Close your eyes, close your ears
And to survive is not meant to be...
Let's sound the alarm together
Because everything is in the answer
How can we live in the new century?
Leading: We begin the third round of our competition "Warm-up".
Competition conditions: each team prepared three questions with their answers and asks them in turn to each other. Thinking time 30 seconds. The jury evaluates the speed, correctness and originality of the answers.
^ Options for questions and answers for students in grade 10
Which substance is quenched with water even though it does not burn? - Calcium oxide (CaO) - quicklime.
What acid is always found in the human stomach, and when it is deficient, it is drunk as a medicine? - Hydrochloric acid (HCL).
What royal drink has not been drunk by any king? Name its composition. - Royal vodka. It is a mixture of concentrated nitric and hydrochloric acids in a ratio of 1:3.
What effect does chloroform have on the human body? - According to the nature of the action, chloroform is a drug. It causes dermatitis, eczema, gastrointestinal disorders. A slight poisoning is accompanied by vomiting, pain in the stomach.
Why do smart housewives put a few ripe apples to them when storing potatoes in the basement? - Ripe fruits of apples emit ethylene gas, which causes inhibition of growth processes. Potato tubers last longer and do not germinate.
Why not make "houses" for birds out of plastic? - Unlike wood, plastic cannot absorb moisture and release it to the outside, so the water vapor released during breathing accumulates, forming high humidity which is detrimental to birds.
What is the source of anthropogenic methane? What effect does it have on the Earth's atmosphere? - Such sources are rice fields, livestock farms, coal mines and garbage dumps. Anthropogenic methane, absorbing infrared radiation of the earth's surface, enhances the greenhouse effect.
What products of combustion are emitted by coal-fired thermal power plants? How do they affect the atmosphere? - Combustion products are CO2, CO, 5O2, ash, etc., they enhance the greenhouse effect.
What kind of flour is inedible? - Inedible flour, but giving bread, these are mineral fertilizers. This is bone, phosphorite, apathetic flour.
What is the relationship between beets and cake? - Both products contain sugar.
What kind of sugar is not eaten? - Lead sugar, i.e. lead acetate, tastes sweet, but it is poisonous.
What oil is called Provence and why? -Best grade olive oil(transparent, fragrant, hardening at -60 ° C, Provence oil is named after the province of Provence in southern France).
Why are the concrete trenches being destroyed, through which the waste of fat-packing plants is drained? - The effluent of fat-combining plants always contains fatty acids, which form calcium soap with cement lime, as a result of which the cement is destroyed and the bond between concrete grains is broken.
7. In 1845, the German chemist Christian. Shenbein accidentally spilled a mixture of sulfuric and nitric acid on the floor. He automatically wiped the floor with his wife's cotton apron, rinsed it, and hung it up to dry over the stove. The apron dried up, but then there was a not very loud explosion and ... the apron was gone. Why did the apron explode? - Threads of cotton fabric are made of cellulose, the composition of the elementary unit of the monomer of which includes three OH groups (hydroxo groups). Under the action of acids, a nitration reaction occurs with the formation of nitrocellulose (pyroxylin), which explodes with the release of heat and gases.
8. On a clear sunny day, Isaac Newton went for a walk and met a shepherd. The shepherd advised the scientist to return home so as not to get caught in the rain. Newton did not heed the advice of the shepherd and was punished. Chilled and wet, he wished to know how the shepherd had managed to predict the weather so accurately. The shepherd replied that a ram had helped him. How? - Before rain and in wet weather, the pores of each hair of the animal are filled with water, the hair swells and lengthens. In dry weather, some of the water evaporates, and the length of the coat decreases.
9. Do human tears have bactericidal properties? - Human tears contain 0.1% proteins, including the enzyme lysozyme, which has a bactericidal effect. Lysozyme quickly and completely dissolves many aerobic bacteria. 10. Why do animals lick their wounds for a long time? - It is not in vain that animals lick their wounds for a long time: in addition to enzymes that kill microorganisms, a special protein was found in saliva that stimulates the reproduction of skin cells and the formation of blood capillaries.
Leading: The next round of our competition is called "Experimenter". From each team are invited - two people.
Your task is to identify several substances by color and with eyes closed by smell.

Leading: Please come to me one participant from each team.
Your task is to get carbon dioxide and explain how you did it.
^ Music sounds, the guys begin to conduct experiments.
Options for obtaining CO2:
pour sodium carbonate and hydrochloric acid into a test tube, CO2 will be released as a result of the reaction;
carry out the reaction of the interaction of chalk with hydrochloric acid;
blow into the calcium hydroxide solution through a glass tube;
just inflate balloon We breathe out CO2.
Leading: Let's move on to the most interesting and exciting round of our competition "Homework".
^ The first contest "What would it mean?"
Leading; Each team was given the task in advance to draw a picture on an environmental theme. Now you will exchange your drawings and try to explain in 30 seconds what you think is drawn on them.
Explanation of the command " SOS »
Whales generally eat plankton.
But this whale eats everything.
Oh, he is illegible - a glutton,
And he threw out a lot of rubbish.
He changed all his dishes
To what floats around.
^ Explanation of the "Vobla" command
If the air is polluted
There will be nothing for us to breathe.
A man will put on a spacesuit,
It's a suit for the new age.
Leading: And now the teams will play environmental scenes.
^ Scene of the "SOS" team
"Two grandmothers"
Two grandmothers enter the stage: Avdotya Nikitichna - rural, Marya Ivanovna - city.
Maria Ivanovna: Hello Avdotya, how are you? How is your health?
^ Avdotya Nikitichna : Oh! Oh! What is health like now? Sugar, they say, can not be eaten, salt too, already meat is harmful. So I decided to become a vegan.
Maria Ivanovna: Who did you decide to become?
Avdotya Nikitichna: By whom, by whom - a vegeterian!
^ Marya Ivanovna: Lord, I came up with some kind of cosmic name. Perhaps you mean vegan?
Avdotya Nikitichna: Well, yes. Yentoy herself, who eats all the vegetables. So I decided to live longer.
^ Marya Ivanovna: And what happens?
Avdotya Nikitichna: Instead of living longer, I almost died earlier.
Maria Ivanovna: How so?
Avdotya Nikitichna: Yes, vegetables are now processed with some kind of nitractors.
^ Marya Ivanovna: Ha, ha, ha! You got it all wrong again! They are called nitrates, they feed plants.
Avdotya Nikitichna: Yes, now they even eat ozone. He had already been eaten so much that even some holes began to appear in the sky.
^ Marya Ivanovna: Oh, don't tell me, my granddaughter said that her fiancé recently flew into some kind of pipe! Maybe in this hole, huh? So he sings a song about it, pitiful, like romances used to be sung. Let's listen to her.
^ Song about the ozone hole
(melody from the film "Cruel Romance")
And in the end I will tell:
My dear flew away in vain,
I want to fly, I'm going crazy
Into the ozone hole, into space.
Maybe I'll find it there
Or maybe meeting an astronaut,
I will pass through the Milky Way
I will marry an Argonaut.
And in the end I will tell:
Run into the ozone hole
I am in dreams every day.
Perhaps, having flown out into a hole,
I will achieve happiness for a moment!
And in the end I will tell..
Leading: The environmental scene will be shown by the Vobla team.
^ The Tale of the Turnip
Grandfather and Grandmother are sitting on chairs on the stage. Behind them, squatting with a large pattern, is a girl - Turnip.
storyteller(reads): Once upon a time there was an old man and an old woman. One day the old man decided to plant a turnip.
The old man pushes back his chair, and everyone sees the sitting Turnip.
Storyteller: And in order for the turnip to grow faster and be tastier, I decided to use the miraculous chemistry.
^ Grandfather comes out with a bag of mineral fertilizers.
Storyteller: He took the "magic powder" and began to sprinkle the turnip. I tried, and I overdid it.
Grandfather pours out the whole bag.
Storyteller: Then the grandfather decided how to water the turnip. He took the still "living water" from the Don and watered the turnip. The grandfather got tired and decided, in order not to go far, to water the turnip with “dead water” from Temernichka. The grandfather watered the turnip well, conscientiously. Has the turnip grown? big big.
^ The turnip gets up.
Storyteller: Grandpa calls grandma.
Grandfather: Look, grandmother, what a turnip has grown - beautiful, but blush! Gotta try it soon.
grandmother: Wait, grandfather, I heard that you first need to check the crop, but you really probably overdid it - you watered the turnip with both “living water” and “dead water”, but poured too many powders!
Grandfather: Yes, okay, grandma, you heard a lot of fears.
^ Grandfather bites off a “piece” of a turnip and falls, writhing on a chair, grandmother is crying ...
Storyteller: This is what an unreasonable and careless attitude towards nature and the sciences can lead to...
^ The team sings a song.
Lyrical - ecological
The harvest has grown
But what is the interest in it,
These vegetables are useless
Even the pig won't eat them.
Chorus:
The retort is spinning, spinning.
Formulas glow.
It's great then
When we open the bowels,
We will build chemical plants,
And the waste will only be water!
We argue a lot about water,
How to save it for everyone
We need to remember everything without words,
You can't even bake bread without it.
The air is cool, fresh,
But we dream horrible dream,
As from varnishes "Curl", "Charm",
Ozone in holes above the ground.
We want to say guys
There are many miracles in chemistry,
All her laws are holy,
She is not afraid of the devil and the devil.
Leading: And now the “Competition of team captains”.
Captains are offered test tasks.
1. ^ What simple substance is the hardest in some cases and very soft in others?

The intensity of the struggle and joy in the world of knowledge,
Support for your dear eyes.
Our KVN is not over here,
We will be resourceful everywhere.
We became friends at KVN very
And together we will be in happiness and in trouble!
And for life on the planet - everyone is responsible!
Facts that make us think
^ 1. Historical reference:
The first protection law environment can be considered an edict English king Edward 1, adopted in 1273, forbidding the use of coal for heating dwellings in London. Violation of the edict was punishable by death.
Under King Edward III, Parliament passed a law in 1336 prohibiting the dumping of rubbish into the Thames.
In the 18th century, Peter 1 forbade dumping garbage into the Neva.
1/3 of the surface of the world's oceans is covered with an oil film, plus industrial effluents and household waste.
changed dramatically chemical composition soil due to excess fertilizer, pesticides, various metals and their compounds, disposal of radioactive substances.
Industrial emissions of carbon monoxide and carbon dioxide, sulfur dioxide lead to air pollution.
In some areas of the planet, local climate changes are already occurring due to air pollution.
Photochemical smog is formed over cities, which includes carcinogenic organic substances that adversely affect the human body.
More than 600,000 tons of freon are released annually into the atmosphere, which leads to the destruction of the ozone layer, and this, in turn, delays UV rays and reduces the intensity of solar short-wave radiation.
Currently, 33% of salt, 60% of magnesium of world production is extracted from the world's oceans.
In the Middle Ages, people extracted only 18 chemical elements from the earth's crust, and at the end of the 20th century, more than 80.
Some countries are already importing fresh water and there are even projects to pump water from Greenland to Europe, and from Antarctica to South America and Africa.
American scientists have calculated that millions of plastic bags, bottles and plastic products. The fact that these objects are found in the stomachs of marine animals has become commonplace.
The Cologne Cathedral, Athens, the Acropolis and other historical buildings have suffered more in the last decade than in all previous centuries!
