All schools are now required to participate in Olympiads. Students are introduced to national competitions at a young age. Science Olympiad exams emphasize concept-based learning and logical thinking, allowing students to compete while also better understanding their own abilities in any subject. This chapter is very important from an olympiad perspective. In this article, you will get detailed information about science chapter 2 for class 4: Animals.

The Science Olympiad is a well-known exam that is held all over India. This test is divided into two levels. The first level is made up of fundamental scientific principles. At the second level, students are tested on sophisticated scientific theories. Students who pass the first round of the Olympiad exam move on to the second round.

So, let’s see detailed notes about science chapter 2 for class 4: Animals.


When we look around us, we notice various types of animals. Animals can be found all over the globe. They differ in size, shape, color, and the types of environments in which they live. Animals are living beings who require food, water, and shelter in order to survive.

Animal classifications include:

Wild Animals – A wild animal is an animal that lives in nature or the forest (without man-made shelter) and must obtain its own food and water. Some of the wild animals are on display at the zoo. Wild animals can be vicious and dangerous. The lion is known as the “King of the Jungle.” Foxes, deer, lions, bears, giraffes, and other animals are examples.

Domestic animal – Domestic animals are animals that rely on humans for shelter, food, water, and general care. House cats, dogs, parakeets, a cow, horse, sheep, pig, and other animals are examples.

Pet animal – Pet animals are domestic animals kept for companionship and entertainment. Pet animals include dogs, cats, parrots, and mynas, among others.

Farm animal – Farm animals are animals that are raised for a specific purpose, such as meat, milk, hair, or something else. Sheep, goats, cows, and buffalo are some examples.

Note: – The situation determines whether an animal is domestic or wild. People domesticate horses, so they are domestic animals, but horses can also be found in the wild, so they are wild animals.

Land animals – Land animals are animals that live almost entirely on land. Peacock, horse, rhinoceros, elephant, giraffe, buffalo, and other animals are examples.

Water animals – Water animals are animals that live in bodies of water. They breathe in water through specialized organs called gills or directly through their skin. Examples include whales, sharks, dolphins, seahorses, octopuses, and fish.

Birds: Birds are animals with feathers, wings, two legs, and a beak without teeth. The majority of birds fly, but some can also swim in the water. Consider the duck.

Insects: Insects are animals that have six legs and usually one or two pairs of wings. Insects are the most numerous animal group. Ladybirds, cockroaches, houseflies, butterflies, grasshoppers, and other insects are examples.

How can animals help us?

  • Animals help us in a variety of ways.
  • Ploughing the field is done with a variety of animals, including ox and bullock.
  • Donkeys, camels, and other animals are commonly used to transport goods from one location to another, particularly in villages.
  • Milk is provided by animals such as cows, buffalos, and goats.
  • We get eggs from chickens and ducks.
  • Sheep are raised for wool, and silkworms are raised for silk. Wool is used to make the clothes we wear. Silk is also used to make clothing.
  • Animals such as dogs guard our homes and make excellent companions for humans.
