Question

Where does acid rain come from?

Slide 26

Answer

Any rainwater has very weak degree acidity. However, during the combustion of natural fuel processing products - in automobile engines, factories and power plants - they are released chemical substances, greatly increasing the acidity of moisture contained in the atmosphere. This moisture eventually falls to the ground in the form of acid rain.

Text content of presentation slides: GAME TECHNOLOGIES in the process of environmental education and upbringing Since 1997, the Children's Ecological Center of the Olekminsky District has been conducting targeted educational and educational work in the field of ecology and natural science.
style.rotation
During this time, a number of original environmental games were developed: - “Thrown March across the Olekma Taiga”, - “Web of Life”, - “Taiga Landing”. These games have been tested at the regional and Russian level and include an element of movement and speed, which children really like. Questions in such games form knowledge about Yakut nature, about local species of animals and plants.

With development information technologies it became possible to apply these innovations in teaching, including using them in conjunction with gaming technologies. As a result, a number of visual electronic environmental games appear in the activities of the DEC: “About the Lesser Brothers...”, “Health Express”, “The Earth is Our Home”, etc. They are designed for students of different ages. We would like to present one of these games to your attention today.

Progress of the game

The game involves students in grades 7-8. Participants gather in assembly hall, a line is drawn. The organizers of the game speak with parting words and wishes for success. Team captains receive route sheets, which consist of several pages: a title page, information pages about the team’s progress through the stages of the game, indicating the composition of the participants, the number of points scored and their maximum quantity at each stage, referee's notes, penalty points, total points, jury members' notes.

The referee plays an important role in the conduct of the game. These are high school students who themselves have participated in such a game before; they have good knowledge and experience. Each of them has instructions for the stage that he is judging. When a team comes to the next stage, the referee is required to read out the instructions for the stage, that is, explain the task. At the end of the game, the results are summed up and the winners are awarded.

Problem 1

On every meter of the 30-kilometer journey to the elevator, a car loses 20 grains of wheat, which is 1 gram. Determine how much grain (in kg) or (in c) the machine loses in 10 trips.

Problem 2

Pigs were bred on neighboring farms, each farmer having 200 pigs. Each pig requires 2 tons of grain to raise. To deliver 1 ton of grain per 1 km, 2 rubles are spent, the distance from the granary to the 1st farm is 1 km, to the 2nd farm is 5 km. How much more money will the second farmer spend on raising pigs than the first?

Problem No. 3

In the southern regions of Ukraine, the most common cows are the Red Steppe breed. To maintain life, a cow needs to receive 4.5 kg of feed units per day. An animal requires 0.5 kg of feed units per liter of milk.

Question: You have 9 kg of feed at your disposal. How much can you get per day if you feed this feed equally to two cows, or give it entirely to one cow?

Problem No. 4

In the Stavropol Territory, prices for purchased sugar beets are set as follows. For each additional % increase in sugar content compared to the base price for 1 ton it increases by 3000 rubles; and for 1 ton of beets received above the plan - by 4,500 rubles.

What is more profitable: getting an additional harvest or achieving an increase in sugar content? Is the farm interested in improving the quality of its products?

Problem No. 5

Neighboring farms sowed 100 hectares of land with the same grain crops. Their lands are identical in fertility, but are located at different distances from the elevator: the first is 10 km, the second is 40 km.

Transporting 1 ton of grain to an elevator over a distance of 10 km costs 40 rubles. The yield on both farms is the same - 2 t/ha. The costs of growing grain are also the same. Determine the profit received first farming due to its proximity to the elevator.

Problem 6

Analyze the following information: one student notebook weighs 40 g; 60 kg of paper are produced from one mature tree; On average, about 500 mature trees grow on one hectare of forest.

Determine how much forest area (in hectares) can be saved if each family (on average 4 people) in our city saves one student notebook per month.

Teams present a song repertoire, instrumental accompaniment, etc. in any field.

Environmental quizzes for high school. Quizzes with answers.

Quizzes for grades 10, 11 on the topic “Ecology around us”

Quiz “Organism and habitat”

1. What is ecology? (Ecology is the science of the interaction of living organisms and their communities with each other and with the environment in which they live. A living organism is a microbe, an animal, and a person. Habitat is soil, forest, air, water - everything that surrounds organism, with what it interacts.)

2. What is the biosphere? (The definition of “biosphere” belongs to the Austrian geologist Eduard Suess (19th century). The doctrine of the biosphere was created by V.I. Vernadsky, an outstanding Russian scientist. The biosphere, according to Vernadsky, is a special active shell of the Earth. It is inhabited by living organisms. In the biosphere, the activities of all living beings together with the person is the most important factor, which transforms the planet.)

4. One day, a naturalist scientist who was studying the life of birds noticed a very large nest on tall pine near the lake. He climbed a tree and saw in the nest big fish. It was fresh pike. What bird settled in this nest? (This nest belongs to a large bird of prey - an osprey. It hunts for fish, like an experienced diver: it rushes down, dives and grabs its prey.)

5. What do you know about Biosphere-2? (It is located in the Arizona desert. This is a huge structure. Created by American scientists. It is isolated from the environment. The purpose of the experiment is to obtain the information necessary for scientists to improve the state of affairs in the large biosphere. All systems of Biosphere-2 operate in accordance with the laws functioning of natural ecosystems based on closed cycles.)

6. Which plant is called a living traffic light? (This is a lungwort that is listed in the Red Book. Like all snowdrops, it is in a hurry to attract the attention of pollinating insects. It regulates insect visits like a traffic light, that is, it changes its color: it becomes alternately blue, purple and pink. Pink color informs insects that the sweet treat, nectar, has ended.)

7. What is the most important substance on Earth? (Water is a liquid without taste, color and odor. Water is part of all living substances, it is found in soil and air. No form of living organism can exist without water. Plants and animals contain from 50 to 99 percent water. Water - source of oxygen in the atmosphere (photosynthesis). Water is a factor that determines climate (it warms and cools slowly, hence the moderating effect on climate). The hydrosphere contains about 1.4 billion cubic kilometers of water; 5 thousand cubic kilometers of water are used annually and are polluted (due to the active technological activity of mankind) almost 10 times more.Some countries are experiencing a shortage fresh water. There is a lot of it on Earth, but people have not learned to use water rationally.)

8. What did Leonardo da Vinci call water? (He called water the juice of life on Earth.)

9. How much water does an adult need per day? (70 kilograms of human body weight contains 50 kilograms of water (70%!). If a person loses 12 percent of moisture, he may die. An adult’s body needs up to 10 liters of water daily. Of this, most of the body’s tissues create themselves (endogenous water), and a person should receive 2 liters of water as part of food or in its pure form.)

10. A unique lake in our country. (This is Lake Baikal. Its approximate age is 25 million years. The lake is fresh. In a clean and clear water Lake Baikal, you can observe objects with the naked eye at a depth of more than 40 meters. The inhabitants of this lake are Baikal omul, golomyanka, seal, sturgeon, taimen. The life of Baikal depends on phytoplankton (a community of algae), zooplankton (representative - the crustacean epischur) and the small fish golomyanka. The golomyanka accounts for 70 percent of the mass of all Baikal fish (about 200 thousand tons). Golomyanka is viviparous. It is in constant movement from top to bottom, to the deepest points of the lake. Thanks to its constant movement, the mass of water moves and is enriched with oxygen. Recently, scientists and environmentalists have increasingly had to raise their voices in defense of Lake Baikal.)

Quiz “Man and the Biosphere”

1. What is pollution? (Pollution is the entry of harmful substances into the environment. Some pollutants have bad influence for the development of the entire biosphere. Anthropogenic pollution (the result of active human activity) exceeds natural pollution, which can be caused by floods, earthquakes, volcanic eruptions, etc. Types of pollution: chemical, biological, electromagnetic, radiation, noise, thermal.)

2. Why is the climate changing? (Causes of climate change - Greenhouse effect, a decrease in the water-regulating capabilities of the land, which occurred due to deforestation large territory forests, draining swamps, plowing large steppe areas, building cities and roads. The control of water evaporation from the land surface is disrupted. Forests have the best water-regulating properties.)

3. Which sea is dying? (The Aral Sea. The beginning of this process is the 50s of the 20th century. This is all due to the increase in areas for cotton and rice crops. An extensive network of irrigation canals took water for crops from the Amu Darya and Syr Darya. The volume of water in the sea has decreased. The surface of the Aral Sea has become three times smaller. The water became salty, the fish died. Even the climate has changed. From the former seabed, the wind lifts dried salt into the air. The result of human activity is an environmental disaster. The yield of fields has decreased, and people’s health has deteriorated.)

4. What is one of the most dangerous sea pollutants? (This is oil. It goes into environment as a result of the mining process and various accidents. People and sea creatures suffer. But some bacteria find it tasty. These are oil-eating bacteria. But during accidents, an amount of oil spills out that bacteria cannot cope with. People have learned to artificially grow “healing” bacteria for the sea. They are stored dry. In case of accidents, they are sown on the oil slick.)

5. What are the dangers of increased energy use? (Increasing energy use is dangerous due to heating earth's surface and ground layers of the atmosphere. Modern technologies are such that approximately one third of the energy of thermal power plants and up to half of nuclear power plants is lost when the units are cooled. Waste water pollutes water bodies. Electromagnetic fields influence the development of living organisms. Average temperature Greenhouse gases also increase the earth's surface. Energy production pollutes the air with nitrogen and sulfur oxides. This contributes to the formation of acid rain.)

6. What is the most environmentally friendly source of energy? (This source is energy saving (opinion of the German scientist D. Seifried). To do this, it is necessary to build and produce houses and appliances with high thermal insulation.)

7. Why are synthetic detergents so dangerous? ( Washing powder, soap, shampoo, soda are serious pollutants of water and soil. They change the surface tension of water, disrupting the life of many organisms that live at the interface between water and air. Getting into water bodies, they impede the access of oxygen. Detergents have a detrimental effect on fish eggs and the development of amphibians. Phosphorus, which is so rich in detergents, promotes the growth of algae (water blooms). Detergents are made from synthetic substances, which makes them difficult to decompose in the natural environment.)

9. When did running water appear? (The Indians kept water in copper vessels. This was about 4 thousand years ago. In Ancient Egypt laid wooden and copper pipes. IN Ancient Rome there was a system of aqueducts. In the 11th century, a real water supply system was built in Novgorod. In the 15th century, a spring water supply system was installed for the Moscow Kremlin. A real water supply system in Russia was built in St. Petersburg in the second half of the 19th century.)

10. What do you know about radioactive fallout? (The polluted atmosphere returns to us the most dangerous consequences human activity (accidents at nuclear power plants, nuclear weapons testing) in the form of radioactive fallout. They are dust and drops of atmospheric moisture. Radioactive atoms (radionuclides) settle as dust on the soil. They also get into our homes, reservoirs, on the skin of animals and people, on the leaves of plants, etc. Radionuclides enter the human body and destroy living cells, weaken its resistance to disease, destroying the genetic apparatus.)

11. What do you know about ozone holes? (Ozone is a form of oxygen. The formula of oxygen consists of two atoms, and ozone - of three. Ozone, which is formed near the surface of the Earth, is harmful (formed during a thunderstorm, the operation of an X-ray machine, etc.). Sun rays, acting on ozone oxides, cause such a dangerous phenomenon as photochemical smog. Widespread use of freon leads to the appearance of ozone holes. The proportion of ozone in some places of the ozone shield is reduced by up to 50 percent. Ozone holes can move. And their existence was first established in the 80s of the 20th century. The holes allow excessive levels of ultraviolet radiation to pass through, leading to skin cancer.)

12. What are pesticides and nitrates? (Pesticides are pesticides that are used to protect plants from pests. Modern Agriculture uses up to 2 million tons of various types of pesticides. They pollute the soil, water and air. They also enter the human body and disrupt vital processes (cancer, allergies, kidney, liver, and stomach diseases). Nitrates are salts of nitric acid. Used as fertilizers. Nitrogen fertilizers increase crop yields. But their excess is deposited in plants in reserve and, together with food, enters the human body. Nitrates help form nitrosamine in the body, an active carcinogen that causes cancer.)

13. Why are accidents at nuclear power plants so dangerous? (Accidents at nuclear power plants are real environmental disasters. They harm the health of millions of people. During accidents, a huge amount of radioactive substances enter the air (isotopes of cesium, strontium - during the Chernobyl accident). The consequences of such accidents affect many decades. The soil is polluted, forest, water. Genetic changes occur in the bodies of animals and people. The human immune system and gene pool are under threat.)

Quiz "Nature Conservation"

1. When did the idea of ​​creating the Red Book arise? (In the 20th century, at the end of the 50s. The International Red Book was first published in 1966, the USSR Red Book in 1978 (six years later - a new, updated edition). The purpose of the Red Book is to identify endangered species of organisms, those that require special protection measures. There is also a Black Book for those species that have disappeared from the face of the Earth forever.)

2. Name a nature reserve near the Pacific Ocean. (This is the Sikhote-Alin Nature Reserve with its Ussuri taiga. The forest occupies more than 90 percent of the area of ​​the reserve. Here you can find rare plants and animals that are listed in the Red Book. Unfortunately, the taiga is being intensively inhabited by humans, which negatively affects its inhabitants.)

3. What do you know about tropical forests? (Their flora and fauna number up to 3 million species, of which only a sixth are described. More than 4 thousand scientists are studying. Tropical forests are rain forests. This is a storehouse of medicinal drugs, many chemical compounds which have great biological activity. The destruction of tropical forests will negatively affect the climate, clean air, water bodies and even food production.)

4. What do you know about folk traditions nature conservation? (Such traditions appeared in ancient times and were passed on from generation to generation. Many peoples, for example, have especially revered trees. For Russians this is birch. And in ancient times the Slavs revered oak. Entire groves were declared sacred. Until relatively recently, Arkhangelsk and Siberian peasants gathered at gatherings. At these gatherings they announced a ban on cutting down trees in forest lands for several years. The ban was called a reserve. This is where the word “reserve” comes from.)

5. Where is the largest nature reserve? (Antarctica is considered the largest reserve. Any human activity is prohibited on the continent and the adjacent expanse of water (according to international treaties). Despite the thickness of the ice, almost 800 plant species were discovered on the continent that were able to adapt to difficult and unfavorable living conditions (frosts up to 70 degrees). Bryozoan and Antarctic amulus are two species of flowering plants in Antarctica. Plants, including lichens, actively develop only a few weeks a year.)

6. Why do we need zoos? (Some people believe that a zoo is a prison for animals. But if you adhere to all the rules for keeping animals in captivity, then they can live in the zoo longer than in the wild. Many animals in the zoo give birth. In this way, a person saves rare animals. This way Moscow Zoo employees preserved the sable.)

7. What is the Noahide principle? (The Noah principle is the name of the theory of species conservation. The criterion of value is the existence of the species itself. This gives it the right to life. Man learns to see the beautiful and amazing on the planet. People have decided that the destruction of biological diversity is not profitable for them. The population of the Earth is growing. And it is necessary feed. And also solve many environmental problems.)

8. What do you know about the bird zoo? (It is located in the Canary Islands. Its area is more than 20 hectares. The zoo is specially equipped so that 300 species of animals and almost 500 species of plants can thrive there. The bird zoo is very popular among tourists.)

9. Tell us about the Askania-Nova nature reserve. (It is located in Ukraine (Kherson region). The area is 11 thousand hectares; 400 species of plants, more than 150 species of shrubs, peacocks, pheasants, eagles, parrots and ostriches feel good among the steppes. The water surface is for black swans, pink flamingos, geese and ducks. In the pastures you can meet Przewalski's horse and buffalo, camel and zebra, roe deer and deer. Scientists are working on creating new breeds of domestic animals.)

10. What do you know about the reserve in western Russia? (The Russian nature reserve in the southern part of the Bryansk forest has been protecting nature (since 1987). Area - 12 thousand hectares. All living things in the forest are protected by law. There are many species of mammals and fish in the reserve, almost 200 species of birds and about 20 species of reptiles and amphibians. Here black storks live - honorary members of the Red Book. Outsiders are prohibited from entering the reserve.)

11. What is the Children's Rainforest? (A 12-year-old Swedish boy named Roland Tiendsuu decided to make an attempt to save the rainforests. He really wanted them not to be lost while he grew up. Together with their classmates and their teacher, the guys began selling cookies for local residents. Things were going well, and they managed to buy 4 hectares of tropical forest in South America. This forest was purchased for a nature reserve in Costa Rica. Other Swedish schoolchildren followed suit and bought another 7 hectares. The grateful management of the reserve called this part of the forest “Children's Forest Forever.” The guys have followers in other countries.)

Development of an ecology event for high school students.

I. Organizational moment.
II. Introduction.

Against the background of the music “Wanderers” the poem sounds:

We cut down forests, arrange landfills,
But who will take everything under protection?
The streams are empty, there are only sticks in the forest.
Think about it, what awaits us next?
It's time for humanity to understand
Wealth from nature, taking away,
That the Earth also needs to be protected:
She is just like us - alive!

In recent years, the word “ecology” has been heard more and more often, more and more alarmingly. If earlier we did not really delve into the meaning of this concept, today we shudder at the terrifying facts of criminal persecution and murder of nature, and this means ourselves. This information bombards us daily, hourly, every minute. The air we breathe, the water we drink, the foods we eat do not in any way correspond to what eliminates illness, lifts our spirits, and gives us confidence in the future. Alas, the situation in Russia is so alarming that I want to shout: “Come to your senses, people, rumors about a global environmental disaster not exaggerated at all!” And in response there is silence...

Poem to the sound of bells:

There is just a temple
There is a temple of science.
And there is also a temple of nature -
With scaffolding reaching out
To meet the sun and winds.
He is light at any time of the day,
Open to us in the heat and cold,
Come here, be a little hearty,
Do not desecrate her shrines!

Today I suggest you hold a tournament of experts on nature, its protection and conservation. Three teams will participate in our tournament. The jury will judge the correctness of answers and completion of tasks. (jury presentation)

Round 3. Baba-Yaga's story.

Let's move on to the third round. (The appearance of Baba Yaga.)

B.Ya. Hello, here I am.
Q. Where did you come from?
B.Ya. Guess where it came from. Now I’ll tell you a riddle.
Its spring and summer
We saw him dressed.
And in the fall from the poor thing
All the shirts were torn off.
B.Ya. Of course I came to you from the forest.

Oh, how I remember. Recently Leshiy and I went to a nearby forest for a picnic. We had such a great time.
Q. I have already heard your story and was horrified. What did you do in the forest? The children will have the task of listening carefully to the story and finding out what Baba Yaga and Leshy did in the forest. Whoever finds the most errors wins. For each correct answer the team receives 1 point.
B.Ya. So it is!

With cheerful music we notified the forest that we had arrived.(Loud music scares away animals and birds). The days were hot, but the heat was not felt so much in the forest. A familiar path led us to a birch grove. Along the way we often came across mushrooms - porcini, boletus, russula. The goblin and I pulled mushrooms out of the ground for distillation. All the mushrooms that we didn’t know were knocked down with sticks.(You should not pull out or knock down mushrooms - the mycelium is destroyed). Halt. We quickly broke branches and lit a fire. (Dry wood is collected for the fire. Fires should not be lit in hot and dry weather.)We brewed tea in a pot, had a snack and moved on. Before leaving, Leshiy and I had a competition to see who could throw away the empty cans and plastic bags next. Well, the microbes will destroy them anyway.(These substances take 100-200 years to break down)the burning coals of the fire winked at us goodbye.(The coals should be covered with earth or filled with water)in the bushes we found a nest of some bird. They held the warm bluish testicles and put them back.(You should not touch bird eggs)the sun rose higher above the horizon. It was getting hotter. We found a small hedgehog at the edge of the forest. Deciding that his mother had abandoned him, they took him with them, maybe he would come in handy.(There is no need to take chicks and animals from the forest)We're already pretty tired. There are quite a lot of anthills in the forest. Leshy decided to show how formic acid is extracted. He planed some sticks and began to pierce the entire anthill with them. A few minutes later we were already happily sucking on ant sticks.. (You should not push anything into the anthill.)Gradually, clouds began to roll in, it began to get dark, lightning flashed, and thunder roared. Went pretty heavy rain. But we were no longer afraid - we managed to run to the lonely standing tree and hide under it.(hiding under a lonely tree during a thunderstorm is dangerous.)We returned to our forest with armfuls of meadow and forest flowers.(Meadow and forest flowers should not be picked.)It was a fun day.

B. Fill out the answer sheets and turn them in to the jury. In the meantime, while the jury is checking the answers, let's say all the mistakes out loud one by one.

B.Ya. I realized what Leshiy and I had done. I’ll run to him right now and tell him everything.

They write poems and songs about everything,
But above all was the legend.

Now the teams will receive a task - legends. They must guess what these legends are about.
1. According to legend, these flowers arose from the tears of Eve, who was expelled along with Adam from the Garden of Eden. The ancestor of the human race wept bitterly, and wherever her tears fell, these flowers bloomed. It was with this flower in his hand that the Archangel Gabriel appeared to the Virgin Mary on the day of the Annunciation to announce to her the birth of a Son who would be great and would be called the Son of the Most High. This flower was on the banners of the French knights. (lily)

2. Its name comes from the word “dulbash” - Turkish turban. In the 17th century, these flowers came to Holland. Their bulbs were terribly expensive. In England, it was believed that their flowers served as cradles for little elves and fairy children, who were rocked and lulled by the wind in these flower cradles. (tulip)

3. Ancient Greek legend narrates: Pan, the god of forests and meadows, once met the beautiful river nymph Sirina, the gentle messenger of the morning dawn. And I was so enchanted by her gentle grace and beauty that I forgot about everything. Pan decided to speak to Sirina, but she got scared and ran away. Pan ran up behind her, wanting to calm her down, but the nymph suddenly turned into a fragrant bush with tender flowers. purple flowers. These bushes are beautiful at night, when it seems that spring itself has plunged into their fragrant sea. They are also good at dawn, when the furry clusters seem to grow from dawn to fog. Lilac.

Oh, you little river,

You won't catch a bass.

Can only be caught with a hook

Either a package or a shoe.

Oh alive read in the water,

Where can I get one?

If you drink from the tap,

You will go to the doctor!

Look here and there -

Where people are, there is rubbish and disgrace.
