Usedto designate a teaching procedure that uses experimentation with apparatus and materials to discover or verify facts and to study scientific relationship. Used not only in the physical sciences but also in home economics and manual arts. Defined as a teaching procedure dealing with firsthand experiences regarding materials or facts obtained from investigation or experimentation.
by John Walton (1966) Togive firsthand experience in the laboratory which may increase student interest Toprovide student participation in original research To develop skill in the use of laboratory equipment and instruments.
Experimental – aims to train pupils in solving with incidental acquisition of information and motor skill. Emphasis: discovery, original procedure, analysis, and solution of problems. Observational – the acquisition of facts is the dominant aim. Facts can be acquired through activities such as visit to museums, exhibits and art galleries, watching demonstrations, listening to lectures, viewing films, and going on field trips.
IntroductoryStep. Includes determination of the work to be done. The teacher should motivate the work at this stage. Work Period.

Explaining the nature and importance of the problem the group had worked on Reporting data gathered or other findings Presentingillustrative material or special contributions Special reporting and exhibition of work by those with individual projectsExhibiting various projects and explanation by their sponsors.
Laboratory exercises should be adapted to broader social needs. Material must be socially valuable and relevant. Problems should be real, interesting, and adapted to the learner’s level. Laboratory exercises must grow out of problems. Laboratory manual should be chosen with care The teacher must be a skillful director of problem solving and of study.
Learning by doing Impressionsthrough several sense make learning more effective Undergoing actual experience is more vivid It is a direct preparation for life.
Uneconomical way of learning Becomes mechanical – at times. The expensive materials sometimes does not justify results. Loss of time occurs due to indiscriminate overuse of the method.
