During the classes
1. Organizational moment.
The teacher greets the students. Filling out the journal, notes the missing.
2. Explanation of new material.
The teacher names the topic and the lesson plan. Theme of the lesson: "Global Internet". The teacher explains the material through presentations. Students write down new concepts and terms under the dictation of the teacher.
Internet - it is a global network of computer networks. There are main communication channels: cable, fiber optic, satellite radio. An appropriate protocol (IP) is required to organize interconnections. Protocol - it is a set of conventions that governs the exchange of data between different programs. An ISP is required to access the Internet. Provider is a company that provides end users with access to the Internet through its local area network.
Brief history of development.
The first non-departmental national computer network was called ARPANET. Its implementation took place in 1969. Its main purpose was the exchange of e-mail and files with scientific and design documentation. The second birth date of the Internet is considered to be 1983. This year saw revolutionary changes in computer communications software. The problem of stability of the global network was solved by the introduction of the TCP / IP protocol, which underlies the worldwide network to this day. So in 1983, the global network NSFNET was formed. In the mid-80s, academic and scientific networks of other countries began to actively connect to it, for example, the UK academic network JANET (Joined Academic Network). The years when the US National Science Foundation ran the global network also went down in history as an era of resolute struggle against attempts to commercialize the network. The network was funded by government funds. The National Science Foundation distributed them among the nodes and financially punished those who tried to make side income from the network. The Internet carries a huge potential for educational services. In the second half of the 80s, the world wide web was divided into domains according to the principle of ownership. The gov domain was financed by the government, the sci domain was financed by the scientific community, the edu domain was funded by the education system, and the com (commercial) domain was not funded by anyone, that is, its nodes had to be developed using their own resources.
The concept of TCP / IP. ARPANET
1972 - an international conference takes place, at which the first network of 40 machines was demonstrated. In 1982 the protocol ARPA arranged in a family TCP/IP(Transmission Control Protocol/Internet Protocol)- a set of multilevel network protocols.
After such events, the Internet "rises to its feet" and becomes the world's largest. By 1987 the network ARPANET
included 10,000 users, by 1989 - their number exceeded 100 thousand. 
In the 1990s, the ARPANET ceased to exist, but the Internet continued to exist. 
Internet today
So,Internet
(English)Internet
) is a global, all-terrestrial system of computer networks connected together, based on the use of a special IP protocol and the transmission (routing) of data packets. 
The Internet is a global information space and serves as the basis and foundation for the functioning ofworld wide web
and other systems . This term is also referred to as "Global Network", "World Wide Web". In abbreviated form, it is simply called "Inet".
At present, when the word "Internet" is used in everyday life, most often it refers to the World Wide Web and the information available on it, and not the physical network itself. 
Today, the Internet has firmly entered the life of a person. He was able to significantly change all spheres of human life in a short time. The Internet is now the fastest, most reliable means of and communication between people. 
With the help of the Global Network, it became possible to find any information of interest, wherever it is located - this is the general availability of materials on a global scale.
Chronology of events
The main Internet services can be divided into three large groups:
Broadcasting;
Interactive;
Search engines.
Broadcasting services are electronic newspapers and magazines. Interactive services include e-mail, various electronic and video conferences, and search services include a wide variety of search robots, catalogers and network rubricators.
Internet services are the basis for the implementation of Internet services. World Wide Web (WWW) - The World Wide Web, originally created in 1992 as a database. The WWW is just one of the important services of the Internet and should not be equated with the Internet itself. WWW is a hypertext multimedia system used for universal access to documents, it can operate with graphics, sound, video, with all types of data presented in computers. To work with the World Wide Web, a special protocol is used - HTTP - Hyper Text Transfer Protocol - a hypertext transfer protocol. In order to navigate the web, you need a web browser - a program for viewing Web pages on the screen.
Browser types
q Mosaic (1993-1995), University of Illinois, USA
q Netscape Navigator (1995 to 2002)
q Internet Explorer (versions 6.0, 7.0), included with Windows, 70%
q Mozilla FireFox (version 2.0), http://www.mozilla.org , 15%
q Opera (version 9.0), http://www.opera.com, 15%
The convenience of the Internet is that almost any information can be found in it, even when we do not know exactly where it is located. If the address of the page with the material of interest to us is unknown and there are no pages with suitable links either, we have to look for materials throughout the Internet. Search engines are used for this. Internet - special web-sites that allow you to find the desired document.
Each search engine has its own characteristics, and the quality of the result depends on the subject of the search and the accuracy of the query formulation. Therefore, when starting to search for information, first of all, you need to clearly understand what exactly and where you want to find. The interface of all search engines is built approximately the same. The user is prompted to enter a query in a special field, and then initiate a search by clicking on a button. The system searches and displays the results in a browser window. In addition, many search engines provide the user with the ability to specify additional search criteria. For example, you can search only in a certain subject category or only certain servers.
The most common search engines are: www.google.com, www.yandex.ru, .
3. Implementation of practical tasks.
The teacher uses a differentiated method of conducting the lesson. It is necessary to answer the question by searching the Internet for the answer, while writing down the address of the page used.

Presentation for the lesson
During the classes
1. Organizational moment.
Hello guys! Sit down!What do you guys think, what is the topic of today's lesson?
You will learn the topic of our today's lesson after you guess the rebus.
Right. This word is Internet. And the topic of our today's lesson is "The World Wide Web Internet"
Today in the lesson we should get acquainted with new concepts: the Internet, what it is intended for. Identify the positive and negative aspects of the Internet.
Motivation
After announcing the topic of the lesson, the teacher asks students to remember everything they know about the Internet, and write this information in the first column of the table “I know - I want to know - I learned (ZKhU)”:
Students in pairs introduce each other to the content of their notes. 2-3 students, at the request of the teacher, report the information they know about the means of storing, transmitting and processing information to the whole group, the rest, if necessary, make additions and clarifications. The teacher writes the basic information on the blackboard.
The teacher invites students to fill in the second column of the table, and to do this, formulate questions about the Internet to which the guys do not know the answers. As a support, students can be offered a list of interrogative questions.words: what, what, how, how much, where, why, when?
After completing the task individually, students discuss questions in groups and choose the most interesting and most important questions for understanding this topic. The teacher also writes them down on the board.
Good! As it turns out, you know a lot about the global Internet! However, can everyone immediately agree with the voiced opinions? Probably not.
So what needs to be done?(Check info.)
Learning new material.
The Internet was created in the 60s of the XX century. It was invented and implemented by the US intelligence agencies, and was supposed to be only for the use of the military, the FBI and no more. In the 80s-90s, many regional, sectoral, national global computer networks were created in different countries. Their association into an international network was called the Internet.
What do you think the Internet is?
Internet - worldwide computer network.
Internet - a combination of computers around the world into a single information network
What device is used to connect to the Internet?
Ordinary telephone lines and modem device, dedicated communication lines.
What is another name for the Internet?
World Wide Web, World Wide Web...
For the first time in the history of Mankind, the worldwide Internet network made it possible to freely exchange any information, without any restrictions (state borders, nationality and religious interests, etc.).
Let's start with the fact that the word Internet, for all of us has already become commonplace and familiar. Each of us can explain the meaning of this owl in different ways, but the meaning often remains the same. So one of the definitions:
Internet is a worldwide system of interconnected computer networks. The Internet is a network of networks!
Sometimes the Internet is also called:
Global network.
World Wide Web or Web.
There are also several well-known slang options:
Inet, no
But where did it all start?
In 1967, the US Department of Defense decided that they needed to create a reliable information transmission system. In turn, DARPA (US Defense Advanced Research Projects Agency) proposed to develop a network that connects remote computers.
The creation of such a network was entrusted to several American universities. The name of the first network was ARPANET (Advanced Research Projects Agency Network). Then the rapid development of computer networks begins.
Now let's talk about what the Internet is used for.
A computer network can perform 2 functions:
- be a means of communication between its users -communication function.
- be a means of access to common information resources -information function.
The means of providing certain information services to network users are calledInternet services.
- Give examples of communication function?
Communication Services.
Email (e-mail).With its help, you can send messages, receive them in your e-mail box, reply to letters from your correspondents automatically using their addresses, based on their letters, send copies of your letter to several recipients at once, forward the received letter to another address, etc. .
- Teleconferencing Service -This is also mail. Letters in the teleconference are sent simultaneously to all conference participants. Each conference is devoted to a specific topic.
Direct Chat Forums(chat conferences). Communication between participants takes place in real time in writing. Participants of the chat-conference are also divided into thematic groups.
Internet telephony– Voice communication over the Web in real time.
Give examples of the information function?
Information Services.
File Transfer Service (FTP).FTP servers store files of various purposes (program files, graphics, sound, documents). These files can be viewed, sorted, copied to your disks.
- World Wide Web (World Wide Web)- a network of documents interconnected by hyperlinks. Each document that has an address is called a Web page. Each Web page is linked to other pages that are stored both on the same computer and on other computers on the Web.
A web page can contain text, pictures, sounds and is stored in a separate file.
Consolidation of acquired knowledge
You can find answers to the questions posed in different ways. Students list sources and search methods: you can refer to a textbook, to any Internet search engine. the teacher suggests visiting sites.
Students sit down at computers, go online, by e-mail, go to one of the virtual museums, study the material.
Students turn to the list of questions and mark those of them that were answered.
The teacher asks students to exchange information on the issues found, that is, organizes the consolidation of the knowledge gained.
Guys, please tell me, is the Internet good or evil for a person?
To do this, let's try to highlight the strengths and weaknesses of the Internet.
Advantages + | Flaws - |
Important source of information | Internet information may be inaccurate |
Communication with people from different cities | A person can go into the virtual world, invent an image for himself when communicating; addicted to the internet |
Purchasing goods and services without leaving home | Fraud by the organization |
Way to spread your knowledge | There are many viruses on the Internet that infect our computer. |
Highlight the virtues Internet and justify your opinion?
Operational search for information;
Communication without borders in real time;
Development of intelligence, creative abilities (a person realizes a new reality with the help of a PC, creates the world)
The possibility of distance learning….
What are the disadvantages of the Internet?
Possibility of false information;
Substitution of real communication with virtual (without realizing it, a person loses the line between the real and virtual world);
Internet addiction (a person falls into slavery to a car, his world moves to the world of a PC - one of the most dangerous dangers of the Internet);
Harm to health.
Results.
So what is the Internet for a person: good or evil? Each of you has your own opinion.
A modern person needs the Internet as a means of obtaining information, communication, but when using the Internet, do not forget about the people around you and your spiritual world!
Reflections.
What new did we learn today?
Was the information in the lesson helpful to you? What is its use?
Where can you use it? What do you think is the most interesting?
What did you learn from the topic?
What would you like to know? (or ask a question they didn't get an answer to).
Homework.
Make a crossword on the topic "Internet"
I also prepared an Internet addiction test for you. Test yourself, your friends and parents. The test is comic, but in every joke there is a share of a joke, and the rest is true!
Thank you for your work! Goodbye!
Final word from the teacher.
Well done! I hope that we have drawn the right conclusion for ourselves: everyone decides for himself whether the Internet is evil or good. We must try to make sure that he is still a friend to us.

Hello guys!
So, the topic of today's lesson is: “The global Internet. Search for information".
Presentation for the lesson (Appendix 1).
In the lesson, we will get acquainted with the Internet, look at the global computer network Internet from different angles, get acquainted with search engines and learn how to search for the information we need (slide 1).
Write the topic of the lesson in a notebook.
Introduction to the topic:
Prepare children for the perception of the topic;
Aim for productive work.
The world has really changed with the advent of the global computer network Internet. Today, without leaving your home, you can meet and communicate with people who are far beyond the borders of your country, purchase various goods and services, and much, much more.
Pay attention to the following statistics. Here we can see how many people currently use the global Internet. And you will surely agree with me that the Internet has become an integral part of our lives (slide 2).
Let's try to find out what is the Internet?
You have been given a definition, but some words are missing from it. Try to restore these words yourself, and then we will write the correct definition in a notebook (2 minutes).
The Internet is ... ... a network that includes ..., ... and ... networks and connects millions ... around the world (slide 3).
Now let's try to highlight the strengths and weaknesses of the Internet.
Advantages
Flaws
Important source of information
Internet information may be inaccurate
Communication with people from different cities
A person can go into the virtual world, invent an image for himself when communicating; addicted to the internet
Purchasing goods and services without leaving home
Fraud by the organization
Way to spread your knowledge
There are many viruses on the Internet that infect our computer.
Now you will be divided into 2 teams. The first group are Internet supporters, and the second group are opponents.
Within three minutes, you need to highlight the main advantages (for group 1) and disadvantages (for group 2) of the Internet.
Analysis, comparison, generalization and statement of own positions.
Team captains prepare a short (2 minutes) speech in which they substantiate the theses of their position.
Speech by the captain of the team of supporters.
Speech by the captain of the opposing team.
The speeches of the captains of the teams show the importance of the Internet in our days and set the rational use of it in order to avoid negative consequences.
Conclusion: We managed to look at the global computer network Internet from different angles. Both positive and negative qualities of it are revealed. Summarizing all of the above, we can conclude that the Internet is a very important source of information, which you certainly need to use, but you should not forget about the problems that a computer network carries..
Restore the definition, write it down in a notebook with the teacher.
They are divided into groups.
Group work.
Retrieve your positions.
Lesson topic:
Learn how to search for information on the Internet;
Consider Internet search engines.
And now we turn to the study of the topic. In the course of my story, you yourself write down the information you need (slides 5-6).
Working in the network, you need to quickly navigate the available amount of information.
There are basically three main types of information retrieval:
Indication of the page address; (slide 7)
This is the fastest way to search, but it can only be used if you know exactly the address of the document or the site where the document is located.
This is the least convenient method, since it can be used to search for documents that are only similar in meaning to the current document.
Access to the search engine (slide 9).
Search server addresses are well known to everyone who works on the Internet. Currently, the following search servers are popular in the Russian-speaking part of the Internet: Yandex(yandex.ru), Google(google.ru) and Rambler(rambler.ru).
Search system provides the ability to search for information on the Internet.
Most search engines look for information on World Wide Web sites. (slide 10)
Guys, what search engines do you know? (yandex.ru, Rambler.ru, Google.ru and many others) (slides 11-12).
Yandex. en
Yandex is a Russian web search engine. The company's website, Yandex.ru, was launched on September 23, 1997.
A distinctive feature of Yandex is the ability to fine-tune the search query. This is implemented through a flexible query language (slide 13).
Google. en
The leader of search engines on the Internet. According to one version, Google is a distorted spelling of the English word googol. "Googol (googol)" is a mathematical term denoting a unit with 100 zeros (slide 14).
Rambler. en
Rambler was founded in 1996.
The Rambler search engine understands and distinguishes between Russian, English and Ukrainian words. By default, the search is conducted by all forms of the word (slide 15).
The main things are written down in a notebook (on their own !!!)
Fixing the material
And now there will be work in pairs. You sit down at computers. You will be given cards on which problematic questions are written. You need to find different points of view on this issue on the Internet, and write down on the cards the url addresses and search engines in which you found the answer to the question posed (Appendix 2).
Individual work on computers.
Summing up the lesson:
systematization of knowledge gained in the lesson
What is a global computer network?
What is a search engine?
What search engines do you know (recognized)?
Evaluation of children for practical work.
