This study analyzed the effects of differentiated experiments adapted to the differentiated and selective 7th curriculum on the development of inquiry ability. And this study studied the perception of students on differentiated experiments. For this study, differentiated inquiry activities on chemical reaction were developed and applied to the experimental group of 10th grade science circle students while the conventional extracurricular science activity lessons were applied to the control group. According to the results, it was found that the students treated with alternative differentiated experiments emphasizing social interactions got higher scores than those with conventional experiments in the test of inquiry ability and learning motivation. The difference was remarkable for the students at transitional and formal operational level, especially in the experimental planning ability. It seems that this ability comes from interactions in the selection process of experiments. And it also showed that students prefer an alternative differentiated experiments to the conventional experiments according to the survey of recognition on the alternative differentiated experiments.
