There is arising several problems doing the practical or laboratory works at school. One of them is that there are no laboratories fitted separated from classes. If the teacher wants to do practical or laboratory work he must ask the pupils to do a part of work at home. This separates the lesson; there are no possibilities to compare properly or to generalize the results of the work. The problem can be solved connecting the lessons; also, this is not always possible because of the elements of the education process organization. My experience shows that there are possibilities to do enormous spread of independent or exploratory work properly organizing the lesson, giving a chance to generalize the work and to make conclusions. When the school got the cameras for microscopes and when all of them were connected with computer the new possibilities have been arisen for education process (1 picture). There are possibilities to show microscopic objects exploring them during the lesson when computer is connected with television. This expands the possibilities of the lesson, saves the time, the work is getting more consequent (3 picture). I am presenting the one version of the lesson using the microscopic camera, computer and television in education process. The chosen structure and the methods of the lesson permit to use productively the time in the lesson. Even if there are no laboratories still there are possibilities to do and to generalize the work. The work groups having less practical working skills are doing their work properly because the information is public. There are enough time to divide the results of the resource and to compare them among the work groups. The data of the research are straighter because the micro-preparations and measurements using for counting are equal. The counting is very comfortable, undemanding for special efforts. The disadvantage of the lesson is that the lesson can be organized only when the equipment is prepared and for this teacher must spend the time. It is easier to do the work with the salt soak than with the sugar soak and this is not mirrors exactly the features of the osmosis.
