The pandit challenged the court to find out his mother tongue.

The pandit says, “ I can speak many different languages”.

I would have used a blade of grass to tickle the pandit’s ear.

He told his son that whenever he lost his temper, he had to hammer a nail into the fence.

Birbal says, “ The pandit’s mother tongue is Telugu”.

The pandit asks, “ Can anyone find out my mother tongue”?

I would have invited the Pandit for a sumptuous feast at my house. While he is relishing the dishes I would have pricked his thighs with a sharp needle. At that he would have cried out in pain in his mother tongue.

‘The Scholar’s Mother Tongue’

The given lesson The Scholar’s Mother Tongue is extracted from Akbar and Biral Stories’. One day Akbar drew a line on the floor of the open court and challenged his courtiers to make it shorter without erasing it. Everyone were puzzled. Birbal at once drew a longer line beside the’ first one, without touching the first one. All the courtiers and Akbar agreed that now the first line is shorter.

Once a learned scholar (Pandit) visits the court of Akbar and introduces himself as a master of many languages, and can speak many languages fluently. He challenges all present there to find out what his mother tongue is.

All the courtiers fail to find out the pandit’s mother tongue. Then Birbal tells the Pandit that he shall find out the Pandit’s mother tongue in a day or two. The pandit agrees. That night Birbal sneaks into the Pandit’s bedroom and finds him fast asleep. He whispers into the pandit’s ear, then he tickles his ear with a feather.

The pandit who was in deep sleep shouted out some words in his mother tongue. He shouts Tevaradi’ in Telugu which means ‘who is that? The next day Birbal declares that the Pandit’s mother tongue is Telugu in front of the whole court. The pandit agrees to it.

Akbar is astonished and congratulates Birbal and asks him how he found out the truth. Birbal explains that in times of difficulty a person speaks his mother tongue. Then he narrates the entire incident that took place in the pandit’s bedroom, the previous night. The Pandit accepts defeat and leaves the king’s court in dismay.

The house bees keep the houses clean and well ventilated . They build new combs to store honey. Field bees are older bees. They go away from the house. Their job is to search for nectar.

We use honey to calm a cough and soothe a sore throat. It kills bacteria.

Yes, the honey bees are hard working. At the time of honev gathering season they work very hard, as a result , a honey bee do not live longer than a month.

1. Bees visit flowers and collect nectar. They store the nectar in their stomachs and cany it to the beehive. The nectar mixes with the proteins and enzymes in their stomachs, The nectar is thus converted into honey. 

2. The bees then drop the honey into the honeycombs. To prepare for long-term storage, the bees fan their wings to evaporate and thicken the honey, and cap the honeycomb with wax.

A honey bee does not live longer than month.

A honeycomb is a hexagonal cell made of wax produced by the bees.

During the spring season, the plants will be full of colorful flowers. I use my long tube like tongue, to suck the nectar from the flower. I store the nectar in my honey sac. In the stomach the nectar get mixed with the proteins and enzymes produced by me and becomes honey.

Then I drop the honey into the honeycombs and fn my wings to make it thick. I fill each honeycomb with honey and cap it with wax.

Yes, I have tasted honey while taking medicinal powder for cough. Yes I have seen a bee hive and a honey comb.

Bees store the honey in the honey combs and cap them with wax.

To prepare for long-term storage, the bees fan their wings to evaporate and thicken the honey.

Honey is used as a natural sweetener. It is also used to make ayurvedic medicine to cure cough and sore throat. It is also used as an antiseptic to cure burns.

Honey contains sugar, protein, iron and calcium

Honey bees gather nectar from flowers and plants. They suck the nectar through their long, tube-like tongues from the flowers and store the nectar in their honey sacs and carry it to the beehive.

Camphor from salt: By sublimation method we can separate camphor from salt.

By crystallisation method, pure solid in the form of crystals can be separated.

Crystallisation is a process that separates a pure solid in the form of its crystals from a solution. The crystallisation method is used to purify solids. For example, the salt we get from sea water can have many impurities in it. To remove these impurities, the process of crystallisation is used.

Crystallisation technique is better than simple evaporation technique as

• some solids decompose or some, like sugar, may get charred on heating to dryness.
• some impurities may remain dissolved in the solution even after filtration. On evaporation these contaminate the solid.

Basic principle : 

To remove impurities from a mixture by first dissolving in a suitable solvent and then crystallising out one component. 

Solutions are sea-water and soda-water remaining is mixtures.

The salt present in sea water may contain impurities in dissolved form. Simple evaporation causes the water to evaporate, leaving the impurities with the salt. In crystallisation, pure solid is obtained in the form of crystals from a solution. So, crystallisation ensures the purity of the product obtained.

Salt from a sea water: To separate salt from sea water evaporation method can be used.
