Ahmet, another student in the same class who participated in the research, drew a round object the inner side of which was painted black which was considered as “pollen” as placed/stuck on stigma, related to the concept of "pollination" in his first drawing he made course teaching. Regarding pollination, it can be said that he had the knowledge about the fact that the pollen should somehow come and settle on stigma.

Ahmet did not write more descriptive information about both concepts in addition to his drawing. The following Picture 3 presents Ahmet’s first drawing before the instruction:Figure
