Chairman’s Note
My Dear Students,
Among the 84 lakh species of living beings, human being stands out unique, special and extraordinary, owing to his reasoning, logical thinking, analytical, comprehension skills and more than anything, his capacity to imagine!
Our vision is limited to a narrow bandwidth, our audibility is limited to a small bandwidth and capacities of our senses are greatly limited. Despite all these limitations, human being is able to climb the top of the evolution ladder. All these are possible because of his skills and intelligence.
There is a budding scientist in every student, who is highly inquisitive and curious about various things happening around him. This curiosity should move us to the next stage of experimentation, observation, analysis and comprehension.
I am sure that ‘Vagdevi Vilas Vignan Patrika’ will kindle the scientific spirit in every student and help to transform into a budding scientist.
I congratulate and thank all those who have contributed to this news bulletin becoming a reality.
- Shri. K. Harish

Imagination is more important than knowledge – Albert Einstein
LKG
What comes first- the hen or the egg?? That’s a rhetorical question. Thankfully our tiny tots are
quite oblivious to it!! While the adults mulled over this question, the little ones enjoyed
learning about the life cycle of the hen. They attentively listened to the story of the friendly hen
that laid eggs and sat on it to keep it warm. They were curious about why the eggs didn’t break,
but were too engrossed in watching the toy hen waddle around. They learnt that the chick and
the chicken are not the same, and that the chick eats it way and becomes a BIG FAT HEN!!!
UKG
This time around our dear tiny tots didn’t just learn about the parts of a bird, but they learnt to
draw one too. Their birds had big, round heads, two beady eyes, long, pointed beaks and oddly
rectangular bodies. They were quick to remind us that birds have a pairs of wings and a pair of
legs. It was quite a sight to watch them copy our actions as they drew.
This month was not just about birds, but about insects and butterflies too. “Insects are all not
scary and bad, there are some kind, gentle ones too” they understood. They were scared indeed,
but that didn’t deter them from learning about the creepy crawlies.
As they marvelled at God’s creation, they learnt about how a tiny egg becomes a beautiful
butterfly. They played with the paper caterpillar and straw butterfly. All in all, we managed to
awaken the ornithologists and entomologists in our little ones!!

All of us do not have equal talent, but all of us have an equal opportunity to develop our talent
-Dr.APJ Abdul Kalam
Bidriware (Kannada: ಬಿದ್ರಿ ಕಲೆ ) is a metal handicraft from Bidar.
It was developed in the 14th century C.E. during the rule of the
Bahamani Sultans. The term 'Bidriware' originates from the
township of Bidar, which is still the chief centre for the
manufacture of the unique metal ware. The metal used is a
blackened alloy of zinc and copper inlaid with thin sheets of pure
silver.
Process of making Bidriware
Bidriware is manufactured from an alloy of copper and zinc (in the ratio 1:16) by casting. The
zinc content gives the alloy a deep black color. First, a mould is formed from soil made
malleable by the addition of castor oil and resin. The molten metal is then poured into it to
obtain a cast piece which is later smoothened by filing. The casting is now coated with a strong
solution of copper sulphate to obtain a temporary black coating over which designs are etched
freehand with the help of a metal stylus.
This is then secured in a vise and the craftsman uses small chisels to engrave the design over
the freehand etching. Fine wire or flattened strips of pure silver are then carefully hammered
into these grooves. The article then is filed, buffed and smoothed to get rid of the temporary
black coating. This results in rendering the silver inlay hardly distinguishable from the
gleaming metallic surface which is now all silvery white.
It is said that the soil of Bidar is very special. No one knows exactly what is so special about it.
Some artisans feel that the soil is away from the sunlight and rain for years and therefore it has
great oxidizing properties. Others believe that the part of the fort from where soil is brought
was a mint and therefore metal extracts in the soil make it unique. The artisans say that the
quality of the Bidri earth is very important and the real art lies in testing the mud which is
necessary for making the articles. It is tasted by the artisans by their tongues and then decided
whether to use it or not. The bidriware is now ready for the final blackening process. Here, a
special variety of soil which is available only in the unlit portions of the Bidar fort is used .It is
mixed with ammonium chloride and water to produce a paste which is then rubbed onto a
heated bidri surface. The paste selectively darkens the body while it has no effect on the silver
inlay. – Compiled by

It is really quite a lot of fun and super simple. For this bit of spooky science, you will need:
A piece of tissue paper
A balloon
Scissors
A head of hair
Spooky Music (optional)
1. First cut out a ghost shape in the tissue as shown about 1.5 inches (4 cm) long and add
some eyes with a marker. If you are using 2-ply tissues, peel apart the 2 layers to get the
tissue as thin as possible. Cut out a few ghosts for more fun and place them on a flat
surface. You might want to make some out of regular paper to compare
2. Blow up the balloon and tie it. Then rub it really fast through your hair for about 10
seconds. This will add a static charge.
3. Slowly bring the balloon near the ghost, and the ghost will begin to rise toward the
balloon. If the balloon is charged enough, the ghost will rise and float right up to the
balloon, even when it is several inches away. With a little practice, you can get the ghost
to rise, float, and even dance around.
How it works?
When you rub the balloon through your hair, invisible electrons (with a negative charge)
build up on the surface of the balloon. The electrons have the power to pull very light
objects (with a positive charge) toward them – in this case, the tissue ghost!
Isn’t it a nice Halloween science idea

We cannot solve our problems with the same thinking we used when we created them-Albert Einstein
13
Quantum mechanics (QM; also known as quantum physics or quantum theory) including
quantum field theory, is a fundamental branch of physics concerned with processes involving, for
example, atoms and photons. In such processes, said to be quantized, the action has been observed to
be only in integer multiples of the Planck constant, a physical quantity that is exceedingly, indeed
perhaps ultimately, small. This is utterly inexplicable in classical physics.
Quantum mechanics gradually arose from Max Planck's solution in 1900 to the black-body radiation
problem (reported 1859) and Albert Einstein's 1905 paper which offered a quantum-based theory to
explain the photoelectric effect (reported 1887). Early quantum theory was significantly reformulated
in the mid-1920s . According to Planck, each energy element (E) is proportional to its frequency (ν):
Max Planck is considered the father of the quantum theory.
The mathematical formulations of quantum mechanics are abstract. A mathematical function, the
wave function, provides information about the probability amplitude of position, momentum, and
other physical properties of a particle.
Quantum mechanics has had enormous success in explaining many of the features of our universe.
Quantum mechanics is often the only tool available that can reveal the individual behaviours of the
subatomic particles that make up all forms of matter (electrons, protons, neutrons, photons, and
others). Quantum mechanics has strongly influenced string theories.
Quantum mechanics is also critically important for understanding how individual atoms combine
covalently to form molecules. The application of quantum mechanics to chemistry is known as
quantum chemistry. Relativistic quantum mechanics can, in principle, mathematically describe most
of chemistry. Quantum mechanics can also provide quantitative insight into ionic and covalent
bonding processes by explicitly showing which molecules are energetically favourable to which
others and the magnitudes of the energies involved. Furthermore, most of the calculations performed
in modern computational chemistry rely on quantum mechanics. A great deal of modern
technological inventions operates at a scale where quantum effects are significant. Examples include
the laser, the transistor (and thus the microchip), the electron microscope, and magnetic resonance
imaging (MRI). The study of semiconductors led to the invention of the diode and the transistor,
which are indispensable parts of modern electronics systems and devices

This experiment is great for testing if hot water molecules really move faster than cold ones. Pour
some water and food colour then compare the result.
What you'll need:
A clear glass filled with hot water
A clear glass filled with cold water
Food color
An eye dropper
Instructions:
1. Fill the glasses with the same amount of water, one cold and one hot.
2. Put one drop of food color into both glasses as quickly as possible.
3. Watch what happens to the food colouring.
What's happening?
If you watch closely you will notice that the food color spreads faster throughout the hot
water than in the cold. The molecules in the hot water move at a faster rate, spreading the
food color faster than the cold water molecules which mover slower.
