THE SCIENCE, TECHNOLOGY, INDUSTRY AND ENVIRONMENT PAVILION (STIP)

The pavilion is more than a science museum. In science museums, the visitors are expected to see things which are exhibited. They are not expected to touch the exhibits. But in STIP, the visitors are welcome to interact with the exhibits so that the scientific principles involved are made clear to them. Almost all basic scientific experiments for school children are arranged in the pavilion so that the children can actually do the experiments leisurely. Apart from routine experimental setups, some of the systems kept ready in the pavilion are,

1
 Demonstration of Resonance
2
Sympathetic vibrations and transfer of energy
3
 Simple Harmonic Motion from Circular motion: Phase and phase difference concept.
4
 Storing of energy by a spring
5
Centre of gravity: Demonstration kit
6
Colours: Newton's colour disc
7
Spectrum: Spectrometer
8
Telescope
9
Electromagnetic Induction: Faraday's experiment
10
