Many institutions around the world run programs to teach astronomy to young children (7 to 11 years old), but it is often very difficult to evaluate the efficiency of the methods and materials employed. Interviews and written tests are usually unsuitable, or at least impractical, for that purpose. Our group of researchers and students of the Observatório do Valongo (Universidade Federal do Rio de Janeiro - Brazil) have been teaching children basic notions of astronomy, especially about the solar system, through games and activities, and we have used children's drawings to evaluate our educational methods and didactic material. The artistic expression of children is strongly linked to their everyday life experiences. This way, their representation of the solar system is influenced by the manner that this concept was formed from their experiences at home and the notions learned at school. To evaluate this perception, before the educational activities take place, the students are asked to make drawings of the solar system, without any further instructions. After the activities at the Observatory, we then ask the children to make a new drawing using the new information that they acquired. Over 400 drawings have been collected and analyzed individually, and a database was developed to keep all the information obtained from them. In order to allow a statistical analysis of the whole sample of drawings, some objective topics were defined. These can be divided in two groups: the first is about the individual presence of components of the solar system (natural satellites, rings around giant planets, comets etc.), and the second is about the relative dimensions of the celestial bodies. For each of these topics, we applied a statistical test to check if there was a significant improvement from the drawings made before the activities to those collected after the activities. We concluded that there was a substantial improvement in most of the topics defined. The result of this analysis is being used to enhance our didactic practices, and improve our ability to introduce basic concepts about our neighborhood in the universe to young children.
