A MIRACLE CALLED HUMAN BODY

The speeding impulse of a brain cell racing at 250 miles-per-hour… the quivering dance of hairs in our ear, so small that 10,000 bunched together are thinner than one strand of hair from our head… the 100-mile trek of a red blood cell, only thousandths of an inch in size, through our vast, tangled network of veins, arteries and capillaries… or the miraculous genetic fusion of parental DNA that signals the beginning of a unique new life. All these extraordinary occurrences are routine events for our bodies, yet almost all are hidden from our view. This miracle is called human body.

Anecdote...Ramanujan's Life

The arithmetic class was in progress. The teacher was solving questions on division. On the backboard were drawn three bananas.
"We have three bananas," the teacher said, "and we have three boys. Can you tell me how many each will get?"
A smart boy in the front row replied, "Each will get one."
"Right," the teacher said. "Now, similarly, if 1,000 bananas are distributed among 1,000 boys, each will get one, isn't that so?"
While the teacher was explaining, a boy sitting in one corner raised his hand and stood up. The teacher stopped and waiting for the boy to speak.
"Sir," the boy asked, "if no bananas is distributed among no one, will everyone still get one banana?" There was roar of laughter in the class. What a silly question to ask!
"Quite," the teacher said loudly and thumped the desk. "There is nothing to laugh at. I will just explain what he means to say. For the division of bananas, we divided three by three, saying that each boy will get one banana. Similarly, we divided 1,000 by 1,000 to get one. What he is asking is that if zero banana is divided among zero, will each one get one? The answer is 'no'. Mathematically, each will get an infinite number of bananas!"
Everyone laughed again. The boys understood the trick arithmetic had played upon them. What they could not understand was why the teacher later complimented the boy who had asked that absurd question.
The boy had asked a question that had taken mathematicians several centuries to answer. Some mathematicians claimed that zero divided by zero was zero. Others claimed it to be unity. It was the Indian mathematician Bhaskara who proved that it is infinity. The boy who asked the intriguing question was Srinivasa Ramanujan. Throughout his life, whether in his native Kumbakonam or Cambridge, he was always ahead of his mathematics teachers.

Memory game for class vi

Dear friends
You can try a simple memory game with your friends to memorize the lists of certain concepts generally. It helps students to memorize big lists faster and permanently. For example while learning about the simple machines U can ask ur the friends to sit in groups which are already made. The first friend speaks "the name of an example of a lever" say........... a sea-saw, the second one says sea-saw and A pair of scissors and the third one says ......"sea-saw, A pair of scissors and lemon squeezer and so on .U will love to play this game and also are able to memorize a long list of examples easily.

Play & learn about biosphere

Dear students,
Here is a small activity U can perform to learn the components of biosphere while playing.

U can perform this activity with ur friends and can learn about habitatwise classification of animals. U can draw three circles on the floor and labelled them as "land", "air" and "water". Now make animal masks and wear them or write the name of an animal on a paper and pin it up on ur shirt. Ask ur friends to settle themselves into those circles according to the living place of the animals they are acting as. They will love and enjoy this activity a lot. And in the meantime U & ur friends will learn about the habitatwise classification of animals in biosphere. . Bye for now!

struggle leads to sucess

Dear friends,
Here I am sharing with U a small story which makes us learn a very useful lesson of life that it is struggle and hard work which makes us achieve sucess in life. so I expect all of U to work hard and achieve ur goals in life.Here is the story for U.

A biology teacher was teaching his students how a caterpillar turns into a butterfly.she told the students that in the next couple of hours,the butterfly would struggle to come out of the cocoon,but no one should help the butterfly.then she left.
The students were waiting and it happened. The butterfly struggled to get out of the cocoon and against the advice of the teacher,one of the students took pity on it and decided to help the butterfly out of the cocoon.he broke the cocoon to help the butterfly so it didn't have to struggle anymore.but ,shortly afterwards ,the butterfly died.
When the teacher returned,she was told what had happened.she explained to the student that it is law of nature that the struggle to come out of the cocoon actually helps, develop and strengthen the butterfly's wings.by helping the butterfly,the boy had deprived the butterfly of its struggle and the butterfly died.
Apply this same principle to our lives.Nothing worthwhile in life comes without a struggle .As parents we tend to hurt the ones we love most because we don't allow them to struggle to gain strength.

So all the best for ur coming session & hope that U'll apply this principle & will achieve ur sucess through hard work & efforts.
