To celebrate International Day of Light 2018 in advance and to fulfill the motive of the chapter “To learn, to teach and outreach”, the Manipal OSA Student Chapter went to “Sri Krishna Balaniketan”, an orphanage housing about 60 children of grade 1 to grade 10.
The chapter reached the orphanage on Friday, May 4, 2018 to find the children awaiting our arrival. The session started off with introduction of OSA, followed by the Manipal OSA Student Chapter and ultimately the introduction to LIGHT. Due to language constraint (local language being Kannada), we explained the simple concepts of light as a form of energy in Kannada.
We then divided the kids into 5 groups as per their age group such that the complexity of explanation could be determined for each group. Our team of 14 members showed them interesting science videos in Kannada to captivate their interest. Following that, we explained to
them concepts of reflection and refraction using Glass slab, prism and water filled glass, basics of Diffraction using the Diffraction grating, concepts of polarization using the polarizer, and the science of total internal reflection using the Hologram. Further, we also explained the working of thermal patch, fluorescence using “sunflower oil and blue laser” and periodic table elements. Most of the tools in the OSA kit and OSA suitcase were utilized and the kids were given hands on experience of the tools for clarification of understanding.
The 2 hour event was wound up giving some sweets and balloons to the kids and showing more science videos. The kids looked very enthusiastic about science towards the end and their fascination led to the satisfaction of our outreach team.
With the concepts of Light explained and having enlightened few kids with knowledge, the International Light Day 2018 was well celebrated, though in advance. We, the Manipal OSA Student Chapter, look forward to reach out to more people and drive their interest towards science.
