POPULARISATION OF BASIC SCIENCE BY PRACTICAL TRAINING CLASSES

As a part of its extension activities programme, the Department of Physics, Sri S. Ramasamy Naidu Memorial College, Sattur – 626 203 conducted practical training classes for the twelfth-standard students of Government Higher Secondary School, N. Subbiahpuram, Sattur Taluk, Virudhunagar District, on 27-12-2024.

On 27-12-2024 at 10:00 AM, 35 students from the Government Higher Secondary School, N. Subbiahpuram, both boys and girls, came to visit our department with their teacher Ms. C. Hanimen@Sangaiah, PG Assistant in Physics. The college provided transport facilities to the students. Faculty members and the department’s senior students were engaged in conducting practical training classes for the students.

After the demonstration, the school students were allowed to do the experiments independently by forming themselves into several batches. The following is the list of experiments demonstrated and done by the students.

1. Determination of the specific resistance of the material of the given coil using a metre bridge.
2. Determination of the value of the horizontal component of the Earth’s magnetic field using a tangent galvanometer.
3. Comparison of emf of two cells using a potentiometer.
4. Determination of the refractive index of the material of the prism by finding the angle of the prism and the angle of minimum deviation using a spectrometer.
5. Determination of the wavelength of a composite light by normal incidence method using diffraction grating and spectrometer (The number of lines per meter length of the grating is given).
6. Investigation of the voltage-current (V-I) characteristics of the PN junction diode.
7. Investigation of the voltage-current (V-I) characteristics of the Zener diode.
8. Investigation of the static characteristics of an NPN Junction transistor in common emitter configuration.
9. Verification of the truth table of the basic logic gates using integrated circuits.
10. Verification of De Morgan’s theorems using integrated circuits.

The event lasts about six hours. Refreshments have been provided to the participants by the college.

            This initiative served as a valuable learning experience for the school students, enhancing their understanding of physics concepts and fostering their interest in the subject. The program highlighted the college’s commitment to community engagement and educational outreach.
