KOKRAJHAR: A science motivational outreach programme was organized by the Physical Society of the Department of Physics, Bodoland University. The programme was inaugurated at Nayekgaon Janapriya High School on Saturday. The objective of the programme was to attract the young and curious minds of school students towards the amazing fields of science through hands on simple demonstration of experiments and interaction with physics faculty of Bodoland University.
The programme is aimed to cover the schools of remote areas of BTR. The two-hour programme was designed with four demonstrations. The first attraction was the interaction of the Sun with the Earth through solar wind plasma. The Sun is an example of the fourth state of matter called plasma and the light and heat from the Sun supports the life systems in the Earth. Because of its very high temperature, the Sun sprays out charge particles called solar wind plasma in all directions. Earth has its ionosphere, forms beautiful aurora in the polar regions due to the interaction of its magnetic field with the solar wind plasma. These Sun-Earth interactions are demonstrated in an indigenously designed laboratory device by producing plasma inside glass chamber.
The second demonstration is for students to experience the basics of rocket science. A simple water rocket is designed and students will be trained to make and lunch the water rocket under expert supervision. The third experimental demonstration is on generation of alternative fuel/energy through breaking down of water molecule. Hydrogen gas is generated in a simple homemade reactor and showing its explosive power. Another simple device meant for demonstrating properties of light propagation through different medium is prepared. This is a teaching equipment made for visual experience of some of the properties of light propagation (reflection, reflection and total internal reflection).
