Science is mostly taught by lecture method and teacher centered method, where students' role is confined to listener. Consequently students memorize scientific concept but don't follow the scientific approach in their daily life. In order to develop scientific approach and attitude among students, It is necessary that science should be taught by employing modern experiment oriented or student centered method. There are many experiment oriented and student centered teaching approaches. Inquiry Based Teaching (IBT) is one of them. This approach discourage rote learning and cramming and ensure students' involvement in learning. Teacher only plays the role of facilitator.
