Anna's Extraordinary Experiments with Weather
"Foooo! Foooo!" Anna Mani blew out all eight candles on her birthday cake. "Happy Birthday, Anna!" shouted her brothers and sisters.
Anna had a big family and a big house on a hill. But on her birthday, she had only one small wish.
Anna tore open her birthday gift and peered in. There was something sparkling inside. "Diamond earrings? Aiyye!" She did not want diamond earrings. They were expensive and useless! Do you know what Anna really wished for? Books, books and more books!
"We have books at home!" said her brother. But Anna had already read those.
"There are more in the library!" pointed out her grandfather. But Anna had read those too!
She marched into her room. "Hmmph!"
Later that day, there was a knock on Anna’s door. But there was nobody outside!
Instead, there lay a big box at her doorstep.
"This better not be more jewellery!" she said loudly. It wasn’t. It was a brand new set of Encyclopaedia books!
"So many books. Hurray!" Anna ran around her house, hugging everyone.
Many years later, and many, many, many books later, Anna found a job in the laboratory of a famous scientist.
"What should I do here?" asked Anna. The scientist pointed to a box.
What do you think she found inside?

"Diamonds? Aiyyyye!" said Anna.
But this time, the diamonds were not to be worn. They were for experiments.
The scientist wanted Anna to find out what makes diamonds shine. So she read books about diamonds.
Books, books and more books!
Being a scientist was the best! She could study anything she wanted. Anna did like things that shine. And what shines brighter than diamonds? The sun! So Anna read books about the sun, sunlight and the weather. Books, books and more books!
Anna did hundreds of experiments. She built many gadgets that could measure the weather of a place.
How sunny is it in Bombay? Anna built a gadget to measure that.
How windy is it in Madras? Anna built a gadget for that too.
Her favourite gadget took many months to build.
It is a special balloon called an ozonesonde. It has a small machine fixed to it. The machine can measure a gas found in air called ozone.
It can fly really high.
Look, there goes Anna’s ozonesonde!
Guess how many gadgets Anna Mani built in all? Nearly one hundred weather gadgets!
She even had her own factory where these were made. It was as if she could build anything!
Anna Mani became one of the wisest weather scientists in India.
Even as she grew older and more well known, her best friends remained the same.
Books, books and more books!

Wonderful Weather Words
Meteorologist (say it like this: ‘meet-your-all-o- jist’): A meteorologist is a scientist who studies the weather and climate of a region. Anna Mani was one of the best meteorologists there ever was!
Ozonesonde (say it like this: ‘oh-zone-sond’): Ozonesondes are balloons which fly high up into the sky. The balloons have gadgets fixed to them which measure the amount of ozone present in the air. Ozone is important because it blocks out harmful light coming from the sun. Too little ozone high up in in the sky means we are in trouble!
If you could be a scientist, what would you want to study?
