It is known that environmental education, which is provided during the pre-school period, where curiosity and interest are at the highest level, raises awareness about the environment in the children. However, it was understood that the studies on environmental education were not at the desired level in this period which is the first stage of education. The purpose of the research in this framework is to identify renewable energy sources resources and to explain the necessity of renewable energy resources for a clean environment, to the pre-school children in the scope of environmental education. The study group of the research constitutes 12 children who are in the age group of 6 years which is training in public institution nursery. Qualitative and quantitative data have been used together in this research, which was prepared as a mixed method. The Environmental Scale (CATES-PV) on which validity and reliability studies were conducted, has been used by Gülay (2011) to obtain quantitative data. The answers that were given by the children to the open-ended questions prepared by the researchers and the pictures that were drawn by the children, constituted qualitative data. In the process of the analysis and interpretation of quantitative data, the pre-test and post-test scores were compared in the direction of answers that were given by the children to the Environmental Scale and a substantial difference was observed in favour of the post-test. As a result of the research, awareness has been raised to the environment as well as teaching the identification and varieties of renewable energy resources, which are abstract concepts. At the same time, museum education activities also played a big role in this result
