Özet:

The purpose of this research is to reveal their pre-school knowledge about the concept of "light" in children. From the qualitative research methods, the study’s work group, which was carried out in accordance with the unique state pattern of the state study in the 2015-2016 educational year, formed 40 children of 60-72 months continuing to an independent kindergarten associated with the Ministry of National Education in the Etimesgut district of Ankara. The research data was obtained through the semi-configured conversation form created by the researchers; audio recordings were taken during the conversations. The data was analyzed by the method of content analysis and included quotes from the expressions of the children. The research found that the calls in the minds of pre-school children about the concept of "light" were artificial and natural sources of light, while the drawings were mostly placed in lamps/lamps. Children have defined light with various characteristics and aspects; most of them have pointed out that it is the color of light. Children expressed the purpose of the use of light as making the event to occur, enlightenment and entertainment. The form of light has not been explained by many children. It has also been determined that children are often unable to define the concept of "light source"; they are given examples of natural, artificial and reflective sources as a source of light. It has been seen that children are often unable to define the concept of "light pollution" and they think that light will not pollute the environment. Accordingly, it can be said that children in the pre-school period have some preliminary knowledge about the concept of "light"; with scientific knowledge about the concepts such as light, light source, light pollution, the child's awareness should be increased.
