Code Title of Programmes Language in Hindi in English
312/V-1 Mechanical Energy Hindi and English 13.55 13.50
This programme aims to complement the relevant lessons in the course and presents the topics in
a lively and interesting way. The basic concepts of work power and energy have been explained with the
help of activities. In order to clarify the phenomenon of conservation of energy, working models available
in the National Science Centre have also been shown. The work done by a constant and a variable
force has been described with the help of real life situations to enunciate the two types of
energy – kinetic and potential. Some practical experiments, animation and diagrams have been included
for visualization.
312/V-2 Surface Tension Hindi and English 17.30 16.33
This programme complements the relevant lessons in the Senior Secondary course. The programme is
based on daily life activities. In this programme, small experiments relating to surface energy have been
conducted under the guidance of experts. Besides explaining the concept of surface energy of a liquid
through experiments/activities, animation etc., certain important phenomena such as capillary
effect and floating of a mosquito on water have been depicted to show the effects and application of
surface tension. Several other important applications of the phenomenon of surface tension have also been
depicted.
312/V-3 Electromagnetism Part-I English – 23.43
The programme is based on Electromagnetism through self induction. This phenomenon of producing the
induced current by changing the current in the same circuit has been shown. In Mutual Induction change in
magnetic flux is directly proportional to the change in current has also been discussed. This programme
enables the learner to understand how mutual induction is used in eddy current inspection.
312/V-4 Electromagnetism Part-II English – 15.37
The programme is based on magnetic effect of current and electromagnetism. The laws related to it and
their application have been described. The phenomena have been presented through demonstration.
Chemistry (313)
313/V-1 The Mole Concept Hindi and English 14.43 14.45
This programme clarifies the concept of mole with the help of demonstration of chemical reactions. It also
deals with how to calculate the number of moles of a substance. It concludes with a brief description of the
uses of molar mass followed by a summary of the concepts discussed in the programme. The programme
explains the meaning of Avogadro Number 3. It also describes the molar masses of different chemical
substances through demonstration.
