The Secret of being always happy

Lippity-lippity, hippity-hoppity down the road, a monkey was found dancing on the streets. A poor dog watches him doing everyday and feels so depressed at his fete. He wished, if he could be as happy as the monkey.

One day, he approached the monkey and asked if there is any reason of being always happy. The monkey replied, you are seeing me everyday dancing on the streets and you thought I do not have any sorrows. But my dear friend, I am doing this all for my master who has trained me to dance. By dancing on the streets.

I am earning money for him and in return he feeds me and gives shelter. I am a slave and have no reason for being happy. At least you are free and master of your own will.

Quiz

Hello Kids, it is happy to hear from you people. I am happy how many of you send your answers

Q: What is the fastest running bird which cannot fly?

Ans: The fastest running bird is the ostrich, but it cannot fly. The ostrich is also the fastest two-legged runner of all the animals on Earth. The ostrich is the largest bird.

Fly

Bird locomotion is quite varied; most can fly, some can run very well, some swim, and some do combinations of these.

Most birds can fly. Flying birds' wings are shaped to provide lift, allowing them to fly. These light-weight animals have adapted to their environment by flying, which makes them efficient hunters, lets them escape from hungry predators (like cats), and takes them away from harsh weather (migration).

The peregrine falcon is one of the fastest birds, and has been clocked at 90 miles per hour in a dive (and some people say that they can dive at over 200 mph).

Birds

Here Kids, today we r going to talk about birds, different types, how they fly, run and swim.

What is a bird?
Birds are warm-blooded vertebrate animals that have wings, feathers, a beak, no teeth a skeleton in which many bones are fused together or are absent, and an extremely efficient,, one-way breathing system. Flying birds have strong, hollow bones and powerful flight muscles.

Most birds can fly. Birds have a very strong heart and an efficient way of breathing - these are necessary for birds to fly. Birds also use a lot of energy while flying and need to eat a lot of food to power their flight.

Flying birds' wings are shaped to provide lift, allowing them to fly. These light-weight animals have adapted to their environment by flying, which makes them efficient hunters, lets them escape from hungry predators (like cats), and takes them away from harsh weather (migration).

Not all flying animals are birds; and not all birds can fly. The ability to fly has developed independently many times throughout the history of the Earth.

How to Remember the Planets in Order

Easy ways to remember the order of the planets (and Pluto) are the mnemonics:
"My Very Excellent Mother Just Sent Us Nine Pizzas" and
"My Very Easy Method Just Simplifies Us Naming Planets"
The first letter of each of these words represents a planet - in the correct order.
  • Mars
  • Venus
  • Earth
  • Mercury
  • Jupiter
  • Saturn
  • Uranus
  • Neptune
  • Pluto
