Students practically verify and discover the laws which govern a certain phenomenon and verify the laws which have been derived from a theory. The scientific study of forces such as heat, light, sound, pressure, gravity and electricity and the way that they affect objects helps them understand the facts and principles of science. Students learn to handle the equipment and apparatus, develop skills to analyse, calculate and measure and present the results with minimal permissible error using proper units. It is fun to learn by practical experimentation.
