Capability developing can be conducted by different means. One of the most effective methods is to use experiments associated with practice. In this article, the author referred the process of conducting experiments associated with practice, investigated the reality of developing capability to apply chemical knowledge for students through practical experiments in some high schools, built assessment tool, from which we designed and used the system of experiments associated with practice in the lectures of Non-Metallic Chemistry, conducted pedagogical experiments and evaluated the effectiveness of developing the capability to applying knowledge for students. http://pubs.sciepub.com/education/8/10/2/education-8-10-2.pdf capability to apply knowledge developing the capability to apply knowledge experiments associated with practice non-metallic
