212/V-6 Simple Machines Hindi and English 12.55 12.30
This programme highlights different types of simple machines like lever, pulley, wheel and axil, inclined
plane, screw, wedge etc., commonly used in our daily life. The working principle of each machine has been
explained through graphics and diagrams. A few illustrations of complex machines like pump,sewing machine,
etc., have also been highlighted in the programme.
212/V-7 Atmospheric Pressure Hindi and English 11.35 11.18
This programme is about atmospheric pressure and its applications in our daily life. With the help of an
experiment, the programme explains that anything having weight pushes or presses other things. Besides
highlighting the factors affecting atmospheric pressure, the programme also displays the units and the
instruments used for measuring atmospheric pressure. Live shots as well as diagrams and animation have
been used to enrich the programme.
212/V-8 Electric Current Hindi and English 12.30 12.15
This programme starts with an introduction to electric current or electricity. The electrons and their flow
have been explained with the help of the experiments. The Coulomb’s Law and its applications have also
been described in the programme. Besides highlighting the conducting and some non-conducting substances,
the concept of resistance and unit of current have also been explained. Definitions, diagrams and equations
have been displayed through graphics and animations at different places.
212/V-9 Electromagnetism Hindi and English 10.35 11.00
The basic concept of electromagnetism and electricity, which we use for our domestic purposes, has been
explained in this programme. In the first half of the programme, electromagnetism has been introduced with
the help of three experiments. The generation of electricity due to the motion of a magnet and its applications
in different domestic appliances like electric motor, fan and generator have been highlighted. The working
principle and uses of electric generator have also been high-lighted. The programme deals with importance
of domestic wiring and highlights various types of wires and household circuits. The basic principle of
working of some of the electrical appliances of common use like electric bulb, electric iron and immersion
heater have also been explained with the help of diagrams and graphics.
212/V-10 Description of Motion Hindi and English 14.30 13.40
Besides describing the basic concept of motion, the difference between rest and motion has been explained
in the programme. The terms like distance displacement, speed and velocity have also been explained with
the help of examples. Further, with the help of live visuals, graphics and animation, uniform and nonuniform
motions have been differentiated. Before concluding, the programme explains acceleration and
retardation with the help of live examples and offers a recap of the programme.
