Class hour.

Topic: "Electrical safety of schoolchildren."

(Age group - 5-6 grade. Can also be used for students elementary school).

Developed by a teacher of the highest category MBOU secondary school No. 18 in Bryansk Zavadskaya E.V.

Tasks:

Culture instillation safe behavior on the street and at home. Inculcate a sense of responsibility for your actions.

Development of cooperation skills with adults and peers in different situations, especially in critical ones, the ability to find ways out of non-standard situations.

Goals:

Introduce students to electrical hazard warning signs. Learn how to behave in life situations related to electricity.

The course of the classroom.

Organizing time. Setting goals and objectives of the lesson.

Guys, today we will talk with you about the electrical safety of schoolchildren. What questions do you think we will consider today?

(Suggested answers for children: We will find out what electricity is and its history. Who discovered and when. What benefits and harms does electricity bring. Causes of electric shock. Signs warning of danger. How to behave in different everyday situations. Test work.)

According to the children's answers, the teacher draws up a "chamomile" on the board, which is a joint statement of the goals and objectives of the lesson and a plan for action.

Teacher: So. We live in modern world and in Everyday life we often meet with electricity. And where is this electricity "around us"?

Estimated student responses: These are various electrical appliances, household appliances, power lines, transformer boxes. And in nature there is electricity in the form of lightning discharges ....)

Teacher: Right. Guys, what is the use of electricity.

Students:(the guys supposedly answer that this is the progress of mankind. This is both television and the Internet. These are various objects household appliances that make our life easier. And, in general, this is a big step in the development of mankind.)

Teacher: What's the harm?

Students:(Children say that with the advent of electricity, life has become simpler and people have begun to move less. There is harm for environment. And also, due to inept handling, electricity can cause physical harm to a person.)

Teacher: Fine. Guys, electricity has such a feature as the absence of factors familiar to humans that cause anxiety or fear. For example, we see and hear approaching vehicles. We can recognize a gas leak by its characteristic smell. And electricity has no color or smell.

Teacher: In preparation for today's class hour, I instructed one of the students to prepare brief reference about electricity. Let's give him the floor.

Student: I learned that we will study electricity in physics lessons. There we learn that electric current can be direct and alternating. That current has power and resistance. And many more interesting facts.

I also learned that the fact of the action of email. current per person was installed in the last quarter of the 18th century. The danger of this action was first established by the inventor of the electrochemical high-voltage voltage source V.V. Petrov. The description of the first industrial electrical injuries appeared much later in 1863 - from direct current and in 1882 - from alternating current.

Teacher: Guys, what do you think, what are the causes of electric shock?

Students(presumptive answers): Touching uninsulated electrical appliances, metal parts of equipment that are energized as a result of damage. Lightning strike. If you climb into the electric booth ...)

Teacher: That's right. Tell me, how to warn about the danger?

Students: Tell about it. Or with signs.

Teacher. A group of students prepared a story about signs. Let's give them the floor.

Pupils show signs and talk about them.(the show is accompanied by presentation slides)

№1 : " Carefully! Electric voltage! - a permanent sign to warn of the danger of electric shock. Used in electrical installations. Attaches to the outside of the door

№2 Permanent warning sign "Caution! Electric voltage» It is used on reinforced concrete poles of overhead lines.

№3. Poster Stop! Voltage!" Used in electrical installations. It is hung out on temporary fences of current-carrying parts under voltage.

№4 Portable poster “Test. Life threatening". Used in electrical installations. It is hung out on fences and equipment of current-carrying parts that are energized in preparation for testing.

№5 Poster "Don't get in! Kill!" Hanging out next to a structure designed to lift personnel to a height

.

Teacher: Guys, do you like cartoons? Sometimes cartoon characters make mistakes too. I suggest you watch 2 plots and find the mistakes of the heroes.

(they watch a plot from the cartoon about Gena the Crocodile and Cheburash, where Gena helps the children organize their leisure time in the yard and climbs into the electric booth under voltage. He is shocked. And also from the cartoon “Well, you wait!” About the wolf and the hare in the studio.)

After watching the plot, a discussion is organized about what Gena and the Wolf did wrong.

5) Teacher: Guys, and now I invite you to show your Creative skills. We will split into groups. You receive a poster that depicts stories of misuse of electricity. You must quickly color it and present your work, accompanying it with poems, which are also offered to you. You can submit your poetry. You should have a mini-presentation scene. correct behavior.. Your task is to be artistic and convincing!

There is work in groups for 5-7 minutes, and then the presentation of team work.

Rushed only to the heights,

How did you get caught on the wire ....

Oh, what should we do, Denis!?

Long pole Denis lacks:

We must free them!

(Unfortunately, he does not know what this threatens him with!)

Children!!! Remember the main rule:

Whether with a stick, a branch, a pole - never

Do not touch the electrical wire

There might be a big problem!!

3rd group:

Standing somehow at the outlet

Little Fedot thought:

“I wonder who is in these

Lives in black holes?

Maybe tiny mice

Two girlfriends, two holes?

Or a tiny raccoon

Settled and lives?

And to check it all,

And to know it all

You need a carnation or a twig,

Or take a wire ... and .... "

Electrical safety rules

To distant villages, cities, Who is walking along the wires? Bright Majesty! This is ... (electricity)

The house is a glass bubble, And a light lives in it. During the day he sleeps, but when he wakes up, he will light up with a bright flame. And in the center of the ceiling the sun hangs, When darkness comes - A light bulb burns in it.

The light does not come from the ceiling, the light comes from my hand. - I turn it on and She, like a home moon, Shines near me, And I read under it. Night. But if I want, I'll click once - and I'll turn on the light.

I will say without boasting: I will rejuvenate all my friends! They come to me sad - With wrinkles and folds, They leave very cute - Cheerful and smooth! So, I am a reliable friend, Electric ... (iron) We have a robot in our apartment. He has a huge trunk. The robot loves cleanliness And buzzes like a liner: “Tu-u-u…” He willingly swallows dust, He doesn't get sick, he doesn't sneeze.

The dry wind dries Curls of my mother. I puff, puff, puff, I don't want to get warm anymore. The lid rang loudly: “Drink tea, the water has boiled!”

There is a box in the bathroom room, It looks with a transparent and round eye. It is interesting to look into the eye when water bubbles in this box. What a miracle, what a box? Himself - a singer and himself - a storyteller, And besides, at the same time Demonstrates a movie.

A hot iron is not a toy, An iron is more dangerous than a gun. Follow him carefully, But the fire is waiting ahead! Do not leave electrical appliances unattended!

If all the appliances at once, you turn on one outlet, You will fire the wiring right away In this room you will get it! Do not overload the power grid!

Spokes in the outlet shoved barely Sparks and flames to the ceiling! Do not put objects and fingers into the socket!

It is better not to turn on a faulty garland, so that firefighters and doctors are not called into the house. Do not use faulty electrical appliances!

Do not pull the plug from the socket by the wire!

Do not climb and do not even approach the transformer box!

Don't throw anything on the wires and don't play around!

Do not touch electrical appliances with wet hands!

Remember and follow the rules of electrical safety!

ELECTRIC ENERGY AND ELECTRICAL SAFETY Teacher of OBZH MKOU Gornobalykleyskaya secondary school: Kharlashin A.V.

Electricity at home

Thanks to electricity, a man flew into space

Thanks to the electric charge, the headlights and control devices of cars work.

Electricity is the engine of civilization development. This situation will continue in the future, although some methods of obtaining electrical energy and transmitting it over a distance will become more efficient, environmentally friendly and more convenient.

The phenomenon of static electricity has attracted the attention of people for many centuries.

Accumulates in a thundercloud electric charge huge values. Then there is a discharge in the form of a giant spark - lightning.

During a thunderstorm, in no case should you approach electrical objects. Often, during a strong wind, a lightning discharge breaks wires on power lines. REMEMBER! TO BROKEN WIRES ON THE GROUND, ON TREES, IN PUDDS DO NOT APPEAR CLOSE THAN 8 METERS!

POWER SUPPLY Energy system

Transformer substations are used to increase and decrease the voltage.

Such information tells people about the danger to life that lurks behind iron doors substations.

The action of electric current has a detrimental effect on the work of all internal organs person. Leads to burns and other serious consequences.

A strong electrical discharge causes cardiac arrest.

Work in electrical installations does not tolerate negligence. Only specially trained electricians can carry out any work on the lines.

Power engineers work only in special dielectric gloves

REMEMBER! It is FORBIDDEN to touch bare wires with bare hands!!!

At home, faulty household appliances are not a toy. If you see bare wires, sparkling sockets, tell an adult immediately. remember, that Electric Energy poses a significant danger to life!

Providing emergency assistance.

Observe electrical safety rules!
