Dexterity With Optics


With a view to encourage, popularize and inculcate scientific temperament among the students, a practical workshop on optics – a branch of Physics that studies the properties of light and construction & use of instruments that detect it, was conducted on the school premises.

Students were exposed to light & lenses by a team spearheaded by Professor Keya Dharamvir, who is a Professor at Department of Physics PU & General Secretary of Society for Promotion of Science & Technology in India (SPSTI), Mr. V K Jindal, Emeritus Scientist, CSIR & Dept. Of Physics PU and Professor Suman Beri, who participated actively in front-line International High Energy Particle Physics Experiments and was the Principal investigator in Discovery of Higgs Boson (God’s Particle) announced on 4th July, 2012 world-wide.
The workshop engaged all the students of class I to IX who were divided into three groups.

Group “A” which comprised students of Class III, were put through a session on Kaleidoscope making, Periscope making, principle of light traveling in a straight line & scattering of light.

Group “B” was made up of students of Classes IV and V who had hands on experience with the Laws of reflection, refraction and they were introduced to lenses, mirrors and telescopes.

Group “C” had students of Classes VI to IX and learnt Telescope & Microscope making, Principles of reflection, mirage explanation, ways to measure velocity of light and the difference between laser source and normal light source among others.

According to Prof Keya Dharamvir
, General Secrearty, Society for Promotion of Science & Technology, SPSTI, “I appreciate the effort made by the school to organize the dexterity with optics workshop. We, at SPSTI, are working towards spreading awareness about science through our outreach programme and the session at Hallmark is part of this endeavour.” A very interesting Sun Gazing session was also held for students in which they saw through telescope the firmament and experienced its magnificence. The practical demonstration of how to use a telescope came to the fore at the activity conducted at the roof top by experts. Large telescopes had been put into place for the same.
Said Ayon Ghosh, A Student, “The workshop literally helped us ‘see light’, arouse the scientist within and certainly in becoming more confident about Physics which became a very friendly subject for us with today’s workshop conducted by luminaries of PU.”.

Mrs. Kavita Wadhwa, Principal said, “In Hallmark School our effort is always to invite the top names in their field to conduct such workshops. Therefore we are honoured to have the professors among our midst. The workshop saw students practically learning the science behind light, lenses and mirrors. Not just these aspects were dealt with by the experts but students even made microscopes and telescopes during the activity.”

Said Mr. Jivtesh Garg, Director, Hallmark School, “The students realized that learning about light and lenses theoretically is not as interesting as seeing and experiencing the real thing.” Apart from the professors, research scholars from Indian Institute of Science Education & Research (IISER), Mohali also participated in the workshop.
