The study object was consisted of 22 sixth grade students from one elementary school of Ta-Tong District, Taipei. The researcher used the courses designed self and semi-structured interviews to obtain the conception cognition of Force and Lever on sixth graders of elementary school. This study was to confer the conception cognition of Force and Lever on sixth graders of elementary school and investigate the understanding, application and difference between different gender, social background and learning achievement. The outcomes of the study were as the following. 1. Most of sixth graders of elementary school just knew the Force can transform the motion condition of the object, could describe the macro-phenomenon of the Force, could accord with the understanding cognition stage of the Force, could use spring’s variations to presume the relationship between two difference objects, could design that conform with experience or practical application. 2. The samples couldn’t realize the effect that Force can transform the shapes of the object, couldn’t describe the micro-phenomenon of the Force, assorted the Force by their intuition or experience, couldn’t accord with the application cognition stage of the Force, couldn’t use spring’s variations to presume the real weight of objects, couldn’t realize the principle about action and reaction, and couldn’t design that lack originality. 3. There were four mistakes among the samples. First, the samples regarded the Force as energy. Second, the samples explained the Force by chinese stylevocabulary. Third, they regarded physical ache and numb as the phenomenon of the Force. Fourth, they usually interpreted the Force by their intuition or experience. 4. Boys expressed copiously and conformed to the concept of Force, describe the phenomenon of the Force, and understand the principle about action and reaction. Girls expressed copiously and conformed to assort the Force, and design about the application of the Force.
