Voyage Summary in English and Tamil

The Horse and the Tiger, The Ape and the Goat, Decided one morning,To hire a boat.

குதிரையும் புலியும் குரங்கும் ஆடும் ஒருநாள் காலையில் தீர்மானித்தன, ஒரு படகை வாடகைக்கு எடுக்க.

To leave their own country, And find a new one, Very much in the manner, Columbus had done.

அவர்களின் சொந்த நாட்டை விட்டுச் சென்று ஒரு புதிய நாட்டை கண்டறிய,கொலம்பஸ் கண்டுபிடித்த அதே மாதிரி தாங்களும் கண்டுபிடிக்க.

The boat went a-sailing, Away and away, It sailed and they sailed, For a night and a day.

படகு பயணித்தது தொலைவான தொலை தூரத்திற்கு அது பயணித்தது, அவர்களும் பயணித்தனர்,இரவு பகலாக பயணம்.

When all of a sudden, There blew a great gale, The Horse was a-tremble,The Tiger grew pale.

அப்போது திடீரென்று ஒரு பயங்கர காற்று வீசியது குதிரை பயத்தால் நடுங்கியது புலியின் முகமும் வெளிறிப்போனது

The Ape and the Goat, Nearly fainted together, But the boat went a-sailing, In spite of bad weather.

அந்தக் குரங்கும் ஆடும் ஏறக்குறைய மயக்கம் போட்ட நிலைக்கு போயின | ஆனால் அந்தப்படகு பயணித்துக்கொண்டே இருந்தது,மோசமான வானிலை இருந்தபோதிலும்.

A-sailing, a-sailing, A-sailing it goes, To a wonderful country, Which nobody knows.

பயணித்து, பயணித்து பயணித்துக்கொண்டே அது சென்றது,ஒரு அழகான நாட்டிற்கு , யாருக்கும் தெரிந்திராத நாட்டிற்கு சென்றது.

The Horse and the Tiger, The Ape and the Goat, Has found a new one, As Columbus had done.

குதிரையும் புலியும்குரங்கும் ஆடும் ஒரு புதிய நாட்டைக் கண்டுபிடித்தன, கொலம்பஸ் செய்ததைப்போலவே.

Question 1.
Why water is a good example for all states of matter?
Answer:
Water is unique because it is the only natural substance that can exist in all three states of matter at the temperatures normally found on Earth! Water is usually a liquid, but when it reaches to 0° C (32° Fahrenheit (F)), it freezes into ice. (Ice is the solid state of water.) When water reaches 100° C (212° F), it boils.

When it begins to boil, some of the water turns into steam. (Steam is the gas state of water, and is also called water vapour.) When steam comes into contact with cool air (which reduces energy), it can condense back into water droplets (liquid again). Those water droplets could then freeze into (solid) ice.

Question 1.
Discuss with your friends.
Rain water harvesting has an important role to protect our environment.
Answer:
Importance of Rainwater Harvesting :
Rainwater harvesting can be a permanent solution to the problem of the water crisis. This is particularly applicable in hilly areas where rainwater harvesting can be utilized for human consumption, for animals and also for farming.
A bad monsoon means low crop yield and shortage of food.

Even animals suffer from a scarcity of water. We face acute water crisis during the summer months. The farmers are the most affected because they do not get sufficient water for their fields. Rainwater harvesting, therefore, is an ideal solution for farmers who depend on monsoon for consistent water supply.

Unavailability of clean water compels the consumption of polluted water, giving rise to water-borne diseases and a high rate of infant mortality.

If rainwater, which comes for free, can be collected and stored, instead of letting it run off, it could be an alternative to back up the main water supply especially during dry spells.

Its importance will not be limited to an individual family but can be used by a community as well. It also creates a sense of social responsibility and awareness about the environment.

The importance of rainwater harvesting lies in the fact that it can be stored for future use. Harvesting rainwater checks surface runoff of water and reduce soil erosion.

In areas having sparse and irregular rainfall, scarcity of water is a persistent problem. It cannot be completely resolved but can be mitigated through rainwater harvesting.

Bujju’s Brave Adventure Summary in English and Tamil

On a nice winter morning, Bujju family set out on a trip to the nearby hill. Bujju cousins Appu, Bala, Surya and Janani accompanied him. The kids were so excited to explore the place.

ஒரு இதமான குளிர்கால காலைப்பொழுதில் புஜ்ஜூவின் குடும்பம் அருகிலுள்ள மலைப்பகுதிக்கு பயணம் செய்ய புறப்பட்டார்கள். புஜ்ஜூவின் மாமாவின் பிள்ளைகளான அப்பு, பாலா, சூர்யா, ஜனனி ஆகியோரும் அவனுடன் சென்றனர். அந்த இடத்தைச் சுற்றிப் பார்க்க அந்தக் குழந்தைகள் மிகவும் உற்சாகம் கொண்டிருந்தனர்.

Mother : Look kids! Be around us. Never go anywhere alone

அம்மா : குழந்தைகளே கவனியுங்கள்! எங்களருகே இருங்கள். தனியாக எங்கேயும் எப்போதும் போகக்கூடாது.

Bujju : Yes ma!

புஜ்ஜு : சரி அம்மா!

Mother : First have your breakfast then, we will go there.

அம்மா : முதலில் காலை உணவை சாப்பிடுங்கள். பிறகு நாம் அங்கு போகலாம்.

Bujju : Ma! See the waterfall.

புஜ்ஜு : அம்மா! நீர்வீழ்ச்சியைப் பாருங்கள்!

Bujju mother started unpacking the food. Meanwhile, the kids could not wait for the parents to take them to the waterfall. So they ran away without informing the parents.

புஜ்ஜூவின் அம்மா உணவை எடுத்துவைக்க ஆரம்பித்தார். இதற்கு நடுவே, பெற்றோர் அவர்களை நீர்வீழ்ச்சிக்கு அழைத்துச் செல்லும் வரையில் குழந்தைகளால் காத்திருக்க முடியவில்லை. ஆகவே, பெற்றோருக்கு தெரியப்படுத்தாமல், அவர்கள் ஓடிவிட்டனர்.

Appu : Run… Run… Run….

அப்பு : ஓடு…… ஓடு……. ஓடு……

Appu : Oh! I feel too hungry. I have only one guava. I shall eat it myself.

அப்பு : ஓ! எனக்கு பசிக்கிறது. ஒரே ஒரு கொய்யா என்னிடம் இருக்கிறது. நானே அதை சாப்பிட்டுவிடப் போகிறே.

Surya : Hey Appu! What are you eating?

சூர்யா : ஹேய் அப்பு! நீ என்ன சாப்பிடுகிறாய்?

Appu : Nothing Surya

அப்பு : ஒன்றுமில்லை சூர்யா.

Appu swallowed and got hiccups. So, Surya and Appu returned to parents.

அப்பு கொய்யாவை விழுங்கினான். விக்கல் வந்தது. ஆகவே சூர்யாவும், அப்புவும் பெற்றோரிடம் திரும்பினர்.

Appa : Where did you go? What about others?

அப்பா : எங்கே போனீர்கள்? மற்றவர்கள் எல்லாம் எங்கே?

Surya : Don’t worry pa. They are playing nearby.

ஆர்யா : கவலைப்படாதீர்கள் – அப்பா . அவர்கள் அருகில்தான் விளையாடிக் கொண்டிருக்கிறார்கள்.

Without noticing, the other three kept running towards the waterfall. There Bala and Janani got diverted on seeing a naughty monkey.

எதையும் கவனிக்காமல் மற்ற மூவரும் நீர்வீழ்ச்சியை நோக்கி ஓடிக்கொண்டிருந்தனர். அங்கே குறும்புத்தனம் கொண்ட ஒரு குரங்கைப்பார்த்த பாலாவும் ஜனனியும் பாதையிலிருந்து திசை மாறினர்.

Janani : Look at that naughty monkey! Let us act like it and have fun!

ஜன்னி : அந்த குறும்புக்கார குரங்கைப்பார்.அது செய்வது போலவே நாமும் செய்து மகிழலாம்!

Bala : I feel very hungry. Let’s go.

பாலா : எனக்கு பசிக்கிறது. வா, போகலாம்.

As Bala and Janani felt hunary, they returned to parents. But Bujju sped towards the waterfall. He was shocked to see that no one was there.

பாலாவும், ஜனனியும் பசி காரணமாக பெற்றோரிடம் திரும்பினர். ஆனால் புஜ்ஜு நீர்வீழ்ச்சியை நோக்கி வேகமாக ஓடினான். அங்கே யாருமே இல்லாததைப்பார்த்துஅதிர்ச்சியடைந்தான.

Bujju : Oh! No… I am alone. Surya, Appu, Janani, Bala… Where are you guys?

புஜ்ஜு : ஓ! நான் தனியாக இருக்கிறேன். சூர்யா, அப்பு, ஜனனி, பாலா…. நீங்கள் எல்லாம் எங்கே இருக்கிறீர்கள்?

Bujju : Is that a ROAR of a lion? Mummy!
புஜ்ஜு : அது என்ன, சிங்கத்தின் கர்ஜனையா? அம்மா!

Bujju : I shouldn’t be afraid. Let me find a way. I think these footprints will help me.

புஜ்ஜு : நான் பயப்படக்கூடாது. போகிற வழியை கண்டுபிடிக்க வேண்டும். இந்த காலடித்தடங்கள் எனக்கு உதவும் என நினைக்கிறேன்.

On his way he finds big footprints.

அவன் சென்ற வழியில் பெரிய காலடித்தடங்களை அவன் கண்டான்.

Bujju : I think these should be Appu’s footprints.

புஜ்ஜு : இவையெல்லாம் அப்புவின் காலடித்தடங்களாக இருக்க வேண்டுமென நினைக்கிறேன்.

Mother : Bujju, where were you? I was so worried.

அம்மா : புஜ்ஜு, எங்கே போனாய்? நான் மிகவும் கவலைப்பட்டுவிட்டேன்.

Bujju : Yes ma… I have found you all at last.

புஜ்ஜி : ஆம், அம்மா …. கடைசியில் நான் உன்னை கண்டுபிடித்துவிட்டேன்.

Now Bujju realised his mistake that he should not go alone without informing parents.

புஜ்ஜு தன் தவறை உணர்ந்தான், பெற்றோரிடம் சொல்லாமல் தனியாக எங்கேயும் போகக் கூடாது.

The Trick Robot Summary in English and Tamil

Vicky was a lazy boy. He never did his homework on time. He never kept his things back in the right place. He pleaded to his father to buy him a robot to do his work. Vicky’s father wanted him to become an active boy. So, he bought him a trick robot. Vicky did not know that it was a trick robot. He was glad to have a robot to do all his work.

தந்திரசாலி ரோபோ  விக்கி ஒரு சோம்பேறி. ஒருபோதும் அவன் தன் வீட்டுப்பாடத்தை சரியான நேரத்திற்கு  செய்ததில்லை. எடுத்த பொருளை சரியான இடத்தில் அவன் திரும்ப வைத்தில்லை. தன்னுடைய வேலைகளையெல்லாம் செய்துதர ஒரு ரோபோவை வாங்கித்தரும்படி அவன் தன் அப்பாவிடம் கெஞ்சினான்.

அவன் ஒரு சுறுசுறுப்பான பையனாக வர வேண்டுமென அவனது அப்பா விரும்பினார். ஆகவே அவர் தந்திரசாலியான ஒரு ரோபோவை அவனுக்காக வாங்கினார். அது ஒரு தந்திரசாலி ரோபோ என்பது விக்கிக்கு தெரியாது. தன் வேலைகளை எல்லாம் செய்ய ஒரு ரோபோ கிடைத்ததை எண்ணி அவன் மகிழ்ச்சியடைந்தான்.

Father: Vicky, I have bought you a robot. This intelligent robot will do all your work. Enjoy!

தந்தை: விக்கி, நான் உனக்கு ஒரு ரோபோ வாங்கியிருக்கிறேன். இந்த புத்திசாலி ரோபோ உன் எல்லா வேலைகளையும் செய்யும்.

Vicky is excited to test his new robot.

அனுபவி! விக்கி தன் புதிய ரோபோவை சோதித்துப்பார்க்க ஆர்வப்பட்டான்.

Vicky: I am hungry. Cook some salad for me.

விக்கி: நான் பசியாக இருக்கிறேன். எனக்கு ஏதாவது கொஞ்சம் சாலட் செய்து கொடு.

Robot: I do not eat salad. So, I cannot make the salad.

ரோபோ: நான் சாலட் சாப்பிடுவதில்லை. ஆகவே என்னால் சாலட் செய்ய முடியாது.

Vicky: What? You are a robot. You cannot refuse me. Clean my room now!

விக்கி: என்ன? நீ ஒரு ரோபோ! நான் சொல்வதை நீ நிராகரிக்க முடியாது. இப்போது என் அறையை சுத்தம் செய்.

Robot: Do you want me to strain my back? I cannot do that.

ரோபோ: என் முதுகுபாதிக்கப்படவேண்டுமென நீ விரும்புகிறாயா? அதை என்னால் செய்ய முடியாது.

Vicky: Really? I cannot believe this! At least, charge my phone.

விக்கி: உண்மையாகவா? இதை என்னால் ‘நம்பமுடியவில்லை. குறைந்தபட்சம். என் கைபேசியையாவது சார்ஜ் செய்து கொடு.

Robot: Why don’t you do that yourself? I must make some calls.

ரோபோ: அதை ஏன் நீயே செய்யக்கூடாது? நான் சிலரிடம் போனில் பேச வேண்டியுள்ளது.

Vicky: Aah! I have a headache now. Get me a cup of hot tea.

விக்கி: ஆ! இப்போது எனக்கு தலை வலிக்கிறது. போய் சூடாக ஒரு தேநீர் கொண்டு வா.

Robot: My battery is draining by listening to you. First, you charge my battery.

ரோபோ: உன் பேச்சை நான் கவனித்ததாலேயே என் மின்கலத்தின் சக்தி குறைந்து போய்விட்டது. முதலில் என் மின்கலத்தை சார்ஜ் செய்.

Vicky: I am tired of you! Play me a pleasant song. I want to relax.

விக்கி: உன்னுடன் பேசி நான் களைத்து விட்டேன். ஒரு சந்தோஷமான பாட்டைப் போடு. நான் ஓய்வெடுக்க விரும்புகிறேன்.

Robot: That’s a great idea! Why don’t you play me one?

ரோபோ: அது ஒரு சிறந்த ஐடியா. எனக்காக நீ ஏன் ஒரு பாட்டு போடக்கூடாது?

Vicky : Oh no! Dad! Please sell this robot. It is totally useless.

விக்கி: அப்பா! தயவு செய்து இந்த ரோபோவை விற்றுவிடுங்கள். இதனால் ஒரு பயனுமில்லை.

Robot: Yes. This time please sell me to an active master. I don’t want to work for lazy people.

ரோபோ: ஆம். இந்தமுறை தயவுசெய்து என்னை ஒரு சுறுசுறுப்பான மாஸ்டருக்கு விற்றுவிடுங்கள். சோம்பேறிகளுக்கு வேலை செய்ய நான் விரும்பவில்லை.

Vicky: Really? Is that why you did not help me?

விக்கி: உண்மையாகவா? அதனால் தான் நீ எனக்கு உதவவில்லையா?

Vicky: No more robots for me! I will do all the work myself.

விக்கி: எனக்கு இனி ரோபோக்கள் தேவையில்லை. என் எல்லா வேலைகளையும் நானே செய்துகொள்வேன்.
