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.

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

Science is nothing but trained and organised common sense - Thomas Huxley

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.
