light lesson

Prepared and conducted by the teachers of the municipal educational institution "Secondary school of the village of Sergievsky of the Saratov district of the Saratov region" Mizyakina Olga Sergeevna,

Tikhonova Nadezhda Alekseevna,

Seryogina Maria Konstantinovna

• 2015 has been declared by the UN General Assembly as the International Year of Light and Light Technologies.
• The purpose of the initiative is to raise awareness of the world community in matters of light, to improve the understanding of new technologies that solve problems in the field of energy in all spheres of human life.
• The year 2015 was chosen as the year of light also because a number of important round dates related to the science of light coincide with it.

• At the request of the Russian Ministry of Education and Science and the Russian Ministry of Energy, UNESCO Director General Irina Bokova wrote down an appeal to teachers and schoolchildren.
• http://www.apkpro.ru/lightyear.html

• Subject:
• “New school - new technologies. Energy saving at school and at home»

The rapidly developing economy of the countries of the planet Earth in the 21st century requires more and more fuel and energy resources. The extraction of oil, coal, gas is increasing every year.

These sources until recently seemed inexhaustible.

Energy saving is an important task

for the conservation of natural resources

energy saving

• Energy conservation - the implementation of legal, organizational, scientific, industrial, technical and economic measures aimed at involving renewable energy sources in the economic circulation.

The main energy saving technologies can be divided into two parameters: spend less and spend smarter:

• 1. The use of energy-saving equipment, this includes energy-saving lamps, and energy efficient electrical appliances that have passed international certification. 2. Energy management at home using the smart home system 3. Insulation of the house will also save more than half of the energy spent during the cold season
• More about energy saving technologies can be found in the eco-house section.

State policy in the field of energy saving.

What is energy efficiency in school? Reducing energy consumption is additional money that can be spent on solving school problems. We believe that a secondary school can save up to 900,000 rubles a year.

YES. Medvedev

The first steps in solving the problem of energy efficiency are proposed to be taken by Russian schools. After all, it is schoolchildren who, having learned to take care of energy at school, will bring this knowledge home, teach everyone at home, and in the future will make a breakthrough in energy saving at

their jobs,

and therefore throughout the country.

• The use of electricity per day costs the state

150,000,000,000 rubles

Do you know that?

• Replacing incandescent lamps with modern energy-saving lamps, on average, can reduce electricity consumption in an apartment by 2 times!
• Up to 70% of a building's heat loss occurs through windows and doors. Batteries often "fry" to the fullest, we are forced to open the windows wide open. At the same time, heat also escapes through non-insulated windows. As a result, we use five times more fuel to heat one square meter than in Sweden, a no less cold country.

Do you know that?

• When the washing machine is not fully loaded, the energy overrun is up to 10-15%! With the wrong washing program - up to 30%.
• If you put a refrigerator in a room where the temperature reaches 30 °C, the energy consumption will double. It is unacceptable to put pots that have not cooled down in the refrigerator.

• When using a vacuum cleaner, a dust bag that is one third full reduces suction by 40%, respectively, the consumption of electricity consumption increases by the same amount.

Energy Saving Tips

at school and at home

• Don't throw money out the window

Taped windows reduce heat loss.

2. Do not block the heat

Not lined radiators are not always beautiful in appearance, but this is a guarantee that heat will freely spread in the room. Long curtains, poorly placed furniture in front of the radiators can absorb up to 20 percent of the heat.

3. More light with less energy

Energy-saving lamps use about 80 percent less energy than traditional incandescent lamps and last 8-10 times longer.

4. Conserve energy in the dining room

If the diameters of the pan and the burner are the same, then the heat is used optimally.

The stove and refrigerator or freezer are bad neighbors! Due to the heat dissipation of the plate, the refrigeration unit consumes more energy.

5. Observe the thermal regime

The heat regulator makes it possible to change the consumed heat depending on the outside temperature.

6. Turn off the light

Make sure that during breaks in the premises, when it is not necessary, the lighting devices are turned off.

Replace incandescent bulbs with modern ones

energy-saving lamps.

Turn off unused appliances

from the network (TV, computer).

Timely remove scale from the kettle.

Do not overdry the laundry, this saves on ironing.

Change dust bags in your vacuum cleaner more often.

Put the refrigerator in the coolest place in the kitchen.

Use light curtains, wallpaper.

Do not cover with thick curtains

heating batteries.

IOrganizing time.

IIIntroduction to the topic.

The problem of energy conservation, as shown by recent events in the Crimea, is very relevant for the peninsula.

The modern period of human development is sometimes characterized through three "E": energy, economics, ecology. Energy in this series occupies a special place.

Energy plays an important role in the development of society. The growth of the world's population from 6.5 billion people at present to an estimated 8.7 billion by 2050 will be accompanied by an annual increase in energy demand by 1.7%.

Therefore, a very serious question has arisen before modern society: what kind of energy of the future will it be? Energy, based on the use of hydrocarbons, has largely exhausted itself. The reserves of hydrocarbons are constantly declining, and their use as an energy source worsens the ecological situation on the planet. Energy consumption is growing exponentially, fossil fuel reserves are also rapidly declining. It is urgent to find new, if possible, cheap, abundant (eternal), sufficiently powerful and environmentally friendly sources of energy.

Priority should be given to increasing the efficiency of electricity use, rather than increasing the capacity of power plants.

3. Energy saving

The growth of energy consumption gives rise to environmental problems: the burden on nature increases, natural resources are depleted. And in the future, perhaps, there will be a shortage of energy. And this can reduce the further development of our country.

Each person should carefully treat the consumed benefits of civilization, water, heat and light delivered to his house.
The problem of energy conservation is relevant not only for our families, schools, regions, countries, but also for the whole world. Saving energy makes it possible to reduce your own costs and have a lower impact on the environment. The need for energy in the world is constantly increasing. Currently, up to 90% of energy is generated from the combustion of organic fossils - coal, oil and gas, the reserves of which are limited and not renewable. How long will they last?

Today at the classroom hour we will talk about energy saving at school and at home. Why do people need to save energy today? The fact is that this problem has always been relevant, and especially now for the country, our school, and family.

What is energy saving?

Energy saving is the cheapest and most environmentally friendly "source" of energy. This is an approach to energy saving based on the use of energy-saving technologies, which are designed to reduce energy losses.

At present, energy saving is one of the priority tasks. This is due to the shortage of basic energy resources, the increasing cost of their production, as well as global environmental problems. The introduction of energy-saving technologies is one of the important steps in solving many environmental problems - climate change, atmospheric pollution (for example, emissions from thermal power plants), depletion of fossil resources, etc. Energy saving is an important factor that improves economic performance and environmental quality.

Energy saving in any area essentially boils down to reducing useless energy losses. At the moment, there are no universal ways to save electricity, but methods, technologies and devices have been developed that help bring energy saving to a qualitatively new level.

4. Ways to save energy

Energy-saving lamp: new century - new light

1. Use of advanced lighting technology (energy-saving lamps, lighting systems).

Advantages of energy saving lamps:

1) Consume 5 times less electricity than LN, with the same light output.

2) They have a long service life - 6-8 thousand hours or more (up to 15 thousand hours).

3) Less load on electrical networks.

4) Fireproof.

Allow to save up to 80% of electricity Economical use of lighting. After observing, I found out that a multi-lamp chandelier on the ceiling provides lighting for the entire room, but leads to unwanted shadow formation when working at a desk, sewing machine, in a corner with toys.

LED lamps LED lamps are the absolute leader in light quality, safety and energy saving. Energy savings reach 50% compared to fluorescent lamps and 90% compared to simple incandescent lamps.

LED life reaches 50,000 hours, which is 100 times the life of an incandescent lamp and 10 times the life of a compact fluorescent lamp. The LED is durable and resistant to mechanical stress and vibration. The LED lamp, unlike fluorescent lamps, does not contain mercury and other harmful substances and does not require any special destruction after use, does not flicker like a fluorescent lamp. In addition, the LED is a low-voltage electrical appliance that almost does not heat up, which means it is electrically and fireproof.
Using natural resources, think about what will happen tomorrow. Will it be “TOMORROW” at all? Today, our planet is on the verge of an ecological catastrophe, and its most formidable harbinger is the greenhouse effect. It is caused by an increase in the content of carbon dioxide in the atmosphere, which is formed in large quantities during the combustion of fuel. The same fuel that is used to provide our apartments with light, heat and water. This means that the fate of our planet depends on each of us, on all mankind, or rather, on how much we consume natural resources!

12. Crockery with a curved bottom can lead to overrun:

10-30% electricity

40-60%. electricity

50-70% electricity

RIGHT ANSWERS:

Question #1

Replacing incandescent lamps with modern energy-saving lamps, on average, can reduce electricity consumption in an apartment by 2 times! The cost of their acquisition pays off in less than a year.

A modern energy-saving lamp lasts 10 thousand hours, while an incandescent lamp lasts 6-7 times less. The 11 W compact fluorescent lamp replaces the 60 W incandescent lamp. The costs pay off in less than a year, and it serves 3-4 years.

Question #2

The habit of leaving equipment in "standby" mode (standby mode) reduces your family budget. Turning off the TV, VCR, music center from the network will reduce electricity consumption by an average of 300 kWh per year.

A mobile phone charger that is left plugged in will become hot even if the phone is not connected to it. This is because the device still consumes electricity. 95% of the energy is wasted when the charger is plugged in all the time.

Question #3

The average cost of producing one cubic meter of water is equal to the cost of producing 1 liter of gasoline.

Question #4

In many European countries, the days of incandescent lamps are already numbered. Europeans will completely abandon them in 2012.

Question #5

The functionality of modern electronic meters allows you to keep records of electricity by zone of the day and even by season. The Regional Energy Commission divided the day into two tariff zones - day (from 7.00 to 23.00) and night (from 23.00 to 7.00) - and set a separate tariff for each. At the same time, the night tariff is significantly lower than the day one, which makes it possible for the population to reduce the cost of paying for electricity. A two-tariff metering system is equally beneficial for both subscribers and the power system. This would significantly reduce production costs, as well as postpone the commissioning of new generating capacities for some time by reducing electricity consumption during peak hours.

Question #6

At present, almost all European household appliances have a special euro sticker with the designation of the energy saving class.

Class "A" includes the most economical devices. Each energy saving class corresponds to a certain level of energy consumption.

For example, washing machines (according to Samsung).

When loading 1 kg of cotton underwear and a temperature of 95 degrees C:

With class "A" 0.19 kWh of energy is consumed;

With class "B", from 0.19 to 0.23 kWh of energy is consumed;

With class "C" it consumes from 0.23 to 0.27 kWh of energy.

Question #7

You have to heat water in any house. Well, if only for tea, otherwise you still have to heat water for washing dishes, laundry. For this, electricity is most often used, even in private homes.

Remember that the water that you do not use will have time to cool before it is needed again, and you will heat it again. Besides, you hardly need extra steam in the house, which you need to pay for? When water is heated on a rustic stove, the advice is also useful.

Question #8

Dusty glass can absorb up to 30% of light. Keep them properly clean!

Question #9

When using a vacuum cleaner, a third-full dust bag reduces suction by 40%, respectively, the consumption of electricity consumption increases by the same amount.

Question #10

Scale is formed as a result of repeated heating and boiling of water and has low thermal conductivity, so the water in the dishes with scale heats up slowly. As a result, energy losses are 20%.

Question #11

When the washing machine is not fully loaded, the energy overrun is up to 10-15%! With the wrong washing program - up to 30%.

Question #12

If the cookware does not match the dimensions of the burner of the electric stove, 5-10% of energy is lost. To save energy on electric stoves, it is necessary to use dishes with a bottom that is equal to or slightly larger than the diameter of the burner. Cookware with a curved bottom can lead to energy waste up to 40-60%. Use the burner at full power only for the time required for boiling. After boiling food, it is advisable to switch to a low-temperature cooking mode. When cooking, it is advisable to close the pan with a lid, since the rapid evaporation of water lengthens the cooking time by 20-30%.

6. Reflection

Living only for yourself does not mean living!
Therefore, we must try
Consume energy wisely
not only great-grandchildren should get it.
Energy is everywhere on earth:
In reserves of oil, gas, timber,
In the mighty winds, in the coal
And in the sun, in the depths of the sea.
Let's build a new world
Where there will be a lot of joy and light,
But the light from the sun, wind and water
And in the future we will achieve success,
And wind turbines forever
Let the nuclear power plants replace
There will never be pollution
And life will change for the better.

GBOU "Special boarding school in Gryazi"

Class hour on energy saving

"Energy saving at home"

Class teacher: M. A. Gladkaya.

2016-2017 academic year year.

Target: attracting the attention of pupils to the problems of energy use, saving energy and energy resources.

Tasks:

· involve schoolchildren in useful activities for energy and resource saving;

· stimulate interest in scientific research and practical application of knowledge acquired at school.

GOOD HOUR

I. Introductory speech by the class teacher

Hello dear guys!

1. Steel cookware with a thick, even bottom ensures good contact with the stove and saves energy. An uneven bottom lengthens the cooking time by 40%. Energy losses with incorrectly selected dishes are 10-15%;

2. The dimensions of the dishes must match the dimensions of the stove. If the dishes are small, you will need more time to cook. If the dishes are large - you lose up to 10% of energy;

3. when cooking in open dishes, energy consumption increases by 2.5 times.

4. Heat loss is the same for slightly ajar dishes and for dishes without a lid and is 2-6%;

5. using a lot of water, you increase the cooking time and spend more energy by 5-9%;

6. by turning off the electric stove 5 minutes before the end of cooking, you rationally use the residual heat and save 10-15% of energy;

7. the use of special utensils - pressure cookers, boilers, coffee makers - allows you to save up to 30-40% of energy and up to 60% of time;

8. use microwave ovens more efficiently. In them, heating and cooking occur due to the absorption of the energy of electromagnetic waves. In this case, the product is heated not from the surface, but immediately throughout the volume;

9. Remove scale from dishes in a timely manner. Scale has a low thermal conductivity, so the water in a scaled dish heats up slowly.

Classroom teacher: Let's give the floor to the fifth speaker with a report on the topic "Consumption and recycling".

Consumption and recycling

In Russia, industry consumes the largest share of energy. What it produces is to a large extent used by other enterprises to produce goods that are consumed by the population or exported abroad. The consumption of goods forms a significant share of our total energy consumption.

What can be done to save energy?

Sometimes you can avoid buying a new thing by fixing the old one. The most energy efficient solution is to use existing things.

If a thing has become unusable, it remains possible to use the materials from which it is made. Recycling for many materials is a great way to reduce landfills and conserve energy. The production of metals of all kinds is very energy intensive, but they can be recycled with much less energy. You can recycle 20 kg of aluminum with the same amount of energy it takes to produce 1 kg of aluminum.

If the best environmentally friendly alternatives (recycling and recycling) are not possible, then incineration for heat production can be discussed. But incineration of garbage is often highly polluting. Mixed waste should never be burned. It is necessary to properly sort the garbage so as not to poison everything around, and burn garbage only in special equipment.

Classroom teacher: Guys, what, in this case, measures should be taken? (ANSWERS OF STUDENTS)

Simple Measures

1. Repair and keep using old things instead of buying new ones.

2. Recycle everything that can be recycled where you live.

3. Buy paper and other things made from waste.

4. Use waste in the production of goods.

III. Behavior of the outcome of the seminar

Energy is all around us in different forms. It has existed since the formation of our universe and will exist as long as the universe exists, turning from one form to another. For life and activity, a person constantly needs energy. Not all forms of energy are equally suitable for practical use by man in his activities, that is, they have different qualities.

A person needs energy in the right form, in the right place and at the right time.

We get the energy we need from energy sources, which are renewable and non-renewable. There are fewer and fewer non-renewable sources. Renewable sources will exist as long as the Sun shines and the Earth exists, but they are obviously not used enough and cannot yet meet the energy needs of modern mankind.

When we use energy to do useful work, some of it inevitably turns into heat and, in the end, is uselessly spent on heating the Universe. We cannot return it from there. In this sense, we can say that part of the energy is lost to us. These are quantitative losses. When transporting energy from the source to the consumer, a considerable amount of energy is also lost.

When energy is converted from one form to another, its quality generally decreases. These are quality losses. As we consume more and more energy, we lose more and more of it. So you can, in the end, lose it all! We are far from the first generation living on Earth and, hopefully, far from the last. But if our predecessors could not think about the consequences of their activities, then we cannot afford it. The skyrocketing energy consumption has not only depleted non-renewable natural resources, but has also harmed nature so much that it sometimes becomes uninhabitable. It's time to think: who are we on Earth and what will we leave behind? Mountains of waste and bare ashes are like careless tourists on a picnic, or, like diligent hosts, a comfortable house with everything necessary for the life of our descendants?

An active energy conservation policy can significantly reduce the consumption of non-renewable energy sources and minimize environmental pollution. These are not nice words, there are specific examples of successful application of energy-saving technologies in the world. It is important to understand that it is necessary to pursue an energy conservation policy at all levels of society - from the United Nations and governments of countries to every citizen.

IV. Reflection

On the board - drawings of light bulbs in three colors: white, yellow, red.

Classroom teacher: If you agree with the words spoken, then go to the green light bulb. If you think that adults should think about energy saving, and not you, then go to the yellow light bulb. And if you think that you don’t need to save energy at all, then go to the red light bulb.

Listen, please, to the words of the authors of the Factor Four report: “A book cannot change the direction of progress. This must be done by people - consumers and voters, leaders and engineers, politicians and journalists. People don't change their habits unless there is good reason to do so. The ecological state of the world requires urgent action. Otherwise, the world may face unprecedented disasters and catastrophes.”

Guys, I think you remember how to save energy. Tell your parents, relatives and friends.

Now it's up to you!

Guys, and now I will ask you to leave your feedback about the class hour.

All those who answered the questions correctly will be called by representatives of the organizers and invited to the prize draw.

And now, attention! Right answers:

1. How many times can energy-saving lamps reduce energy consumption in an apartment? Answer: 2

Replacing incandescent lamps with modern energy-saving lamps, on average, can reduce electricity consumption in an apartment by 2 times! The cost of their acquisition pays off in less than a year.

A modern energy-saving lamp lasts 10 thousand hours, while an incandescent lamp lasts 6-7 times less. The 11 W compact fluorescent lamp replaces the 60 W incandescent lamp. The costs pay off in less than a year, and it serves 3-4 years.

2. What percentage of electricity is wasted if a cell phone charger is left plugged in? Answer: 3

The habit of leaving equipment in "standby" mode (standby mode) reduces your family budget. Turning off the TV, VCR, music center from the network will reduce electricity consumption by an average of 300 kWh per year.

For example, if you watch TV 6 hours a day, then its consumption in standby mode is 297 Wh per day, and almost 9 kWh per month. Similar calculations for a music center give almost 8 kWh per month, a VCR - almost 4 kWh per month. In total, only for three devices - almost 21 kW / h per month.

A mobile phone charger that is left plugged in will become hot even if the phone is not connected to it. This is because the device still consumes electricity. 95% of the energy is wasted when the charger is plugged in all the time.

3. The average cost of producing one cubic meter of water is equal to the cost: Answer: 2

The average cost of producing one cubic meter of water is equal to the cost of producing 1 liter of gasoline.

4. In what year was the presentation of the Edison incandescent lamp? Answer: 2

The "presentation" of Edison's incandescent lamp took place on the eve of 1880. Three thousand people who came to Menlo Park that evening were shocked by what they saw: hundreds of light bulbs shone brightly on a wire stretched between the trees.

5. In what year was the energy-saving lamp invented? Answer: 2

For almost the entire 20th century, Edison lamps had no worthy competitor. A breakthrough in household lighting was made only in 1976, when the inventor Ed Hammer presented to General Electric a fundamentally new lamp, which later became known as an energy-saving lamp.

6. In what year will Europe ban incandescent light bulbs? Answer: 1

In many European countries, the days of incandescent lamps are already numbered. Europeans will completely abandon them in 2012.

7. What types of electricity meters are more profitable to use in everyday life? Answer: 2

The functionality of modern electronic meters allows you to keep records of electricity by zone of the day and even by season. The Regional Energy Commission divided the day into two tariff zones - day (from 07:00 to 23:00) and night (from 23:00 to 07:00) - and set a separate tariff for each. At the same time, the night tariff is significantly lower than the day one, which makes it possible for the population to reduce the cost of paying for electricity. A two-tariff metering system is equally beneficial for both subscribers and the power system. This would significantly reduce production costs, as well as postpone the commissioning of new generating capacities for some time by reducing electricity consumption during peak hours. This metering system allows you to significantly save on electricity bills if you properly organize the use of some household electrical appliances.

8. What is the most economical class of household appliances: Answer: 1

At present, almost all European household appliances have a special euro sticker with the designation of the energy saving class.

Class "A" includes the most economical devices. Each energy saving class corresponds to a certain level of energy consumption.

For example, washing machines (according to Samsung).

When loading 1 kg of cotton underwear and a temperature of 95 degrees C:

With class "A" 0.19 kW / h of energy is consumed;

With class "B" it consumes from 0.19 to 0.23 kW / h of energy;

With class "C" it consumes from 0.23 to 0.27 kW / h of energy.

9. What water is easier and faster to clean the lime from the floor? Answer: 2

You have to heat water in any house. Well, if only for tea, otherwise you still have to heat water for washing dishes, laundry. For this, electricity is most often used, even in private homes.

Remember that the water that you do not use will have time to cool before it is needed again, and you will heat it again. Besides, you hardly need extra steam in the house, which you need to pay for? When water is heated on a rustic stove, the advice is also useful.

Use hot water for domestic purposes only where it is indispensable. Wherever possible, use cold.

For example, fat is washed off much better with hot water, but if you need to wash off lime from the floor or objects, then it will be easier and faster to do this with cold water. Cold settled water is also more useful for watering flowers.

10. What percentage of sunlight is absorbed by dirty windows? Answer: 1

Dusty glass can absorb up to 30% of light. Keep them properly clean!

11. A full dust bag in a vacuum cleaner increases energy consumption: Answer: 3

When using a vacuum cleaner, a third-full dust bag reduces suction by 40%, respectively, the consumption of electricity consumption increases by the same amount.

12. Scale in an electric kettle increases energy consumption: Answer: 2

Scale is formed as a result of repeated heating and boiling of water and has low thermal conductivity, so the water in the dishes with scale heats up slowly. As a result, energy losses amount to 20%.

13. When the washing machine is not fully loaded, the energy overrun is: Answer: 1

When the washing machine is not fully loaded, the energy overrun is up to 10-15%! With the wrong washing program - up to 30%.

14. Cookware with a curved bottom can lead to overrun: Answer: 2

If the cookware does not match the dimensions of the burner of the electric stove, 5-10% of energy is lost. To save energy on electric stoves, it is necessary to use dishes with a bottom that is equal to or slightly larger than the diameter of the burner. Cookware with a curved bottom can lead to energy waste up to 40-60%. Use the burner at full power only for the time required for boiling. After boiling food, it is advisable to switch to a low-temperature cooking mode. When cooking, it is advisable to close the pan with a lid, since the rapid evaporation of water lengthens the cooking time by 20-30%.

Recovery days!

We live in the days of recovery!
Acts 3:21 promises us that before Jesus comes, God will bring about a great restoration on the earth. This will be the time when God, in the truest sense of the word, will restore everything! And this is also a Jewish concept! The Jews believe in the coming times when the entire universe will be restored. The Hebrew word for such a restoration of everything is Tikkun ha Olam! I believe that this recovery time has already begun!

This is partly seen in the revival of Messianic Judaism. God brings the Jews to their Messiah! But God also wants to see the revival of His church! God's presence cannot dwell in a pagan-filled church! He encourages the church to return to its roots. He restores our lost heritage! He is calling His church to BECOME the "One New Man" when Jews and Gentiles enjoy the riches of God's New Testament together!

In Ephesians 5, God portrays the Church as the bride of Christ. It also promises that in preparation for His coming, God will do an incredible work to prepare His bride! God will wash her in the Word and cleanse her so He can present her to Himself as a glorious bride without spot or wrinkle.
I believe we are living in a day when what is written in this passage is being fulfilled. God is preparing His bride! He is restoring His CHURCH!

I believe that we will see the church rise in power and glory such as we have not seen since the 1st century. It won't be like the church we knew at all. And many people from traditional churches will be the first to oppose it. But for those who yearn for God, this will be the fulfillment of their deepest yearnings!

We live in one of the most wonderful days in all of history! The power of God is restored! His Spirit is poured out! God invites YOU to join the recovery process!
Let God bring you back to your ROOTS!
Let God bring you back to His PRESENCE!
THE MESSIAN CHURCH is back!
