The results of space studies are used in many applications, including the education. Work with the schools is a natural method to inform the general public about the role and value of space studies for humanity. The first Russian- Australian scientific- educational micro-satellite "Kolibri -2000" of total mass of 20,5 kg, on 20 March, 2002, has been injected into orbit of International Space Station (ISS) by separation from the transport vehicle 'Progress'. It began the development of tasks for scientific- educational micro-satellite (SEM). In spite of small size, SEM had 3.6 kg of scientific payload, which provides an opportunity to carry out rather wide scientific studies both in the field of "classical" space physics and for the space weather, atmosphere- ionosphere connections etc., it serves also for the tasks of space education. According to the preliminary ballistic calculations, "Kolibri-2000" had to fly about 4 months; however, 17-20 April of 2002 the rapid reduction of its height began, first of all due to the increase in the Sun activity. In this paper we address the influence on the ionosphere of the processes, which occurred on the Sun of 14-24 April of 2002; changes in the flows of energetic particles, magnetic and electric fields has been examined.
