Internet (International network) is initially developed as means for the exchange of data in CERN laboratories. Today, just 10 years after the beginning of its worldwide use, Internet has completely changed a way of creation and search for information. Although originated in the scientific community, Internet has very quickly become means for mass media and communication. In parallel with the development of the Internet, starts its use in education. Internet is today the biggest library and (virtual) laboratory in the world. Creative use of its resources can essentially improve quality of physics education.
Traditional physics lectures based on analytical solutions to known problems poorly reflects the professional activity of most physicists. They widely use computers in their research including search for data from the Internet. Use of Internet resources makes physics classes more attractive to students and gives them direction for lifelong learning. Besides, it enables activities that are not limited by class time.
Unfortunately, importance and all possibilities of Internet resources have not yet been fully recognized. Physics teachers should be trained to use educational resources from the Internet. It has to be part of university curricula, while older teachers can be thought at the seminars and meetings. One example of such activity will be given.
