Answer:
The higher secondary stage is the most crucial and challenging stage
of school education because at this stage the general undifferentiated
curriculum changes into a discipline-based, content area-oriented
course. At this stage, students take up physics as a discipline, with
the aim of pursuing their future careers either in basic sciences or in
science-based professional courses like engineering, medicine,
information technology etc.
Physics deals with the study of matter and energy associated with the
inanimate as well as the animate world. Although all branches of
science require experimentation, controlled laboratory experiments
are of central importance in physics. The basic purpose of laboratory
experiments in physics, in general, is to verify and validate the
concepts, principles and hypotheses related to the physical
phenomena. Only doing this does not help the learners become
independent thinkers or investigate on their own. In view of this,
laboratory work is very much required and encouraged in different
ways.These may include not only doing experiments but investigate
different facets involved in doing experiments. Many activities as well
as project work will therefore ensure that the learners are able to
construct and reconstruct their ideas on the basis of first hand
experiences through investigation in the laboratory. Besides, learners
will be able to integrate experimental work with theory which they are
studying at higher secondary stage through their environment.
The history of science reveals that many significant discoveries have been
made while carrying out experiments. In the growth of physics,
experimental work is as important as the theoretical understanding of a
phenomenon. Performing experiments by one’s own hands in a laboratory
is important as it generates a feeling of direct involvement in the process
of generating knowledge. Carrying out experiments in a laboratory
personally and analysis of the data obtained also help in inculcating
scientific temper, logical thinking, rational outlook, sense of self-confidence,
ability to take initiative, objectivity, cooperative attitude, patience, self-
reliance, perseverance, etc. Carrying out experiments also develop
manipulative, observational and reporting skills.
