Grade 3CBSE

Review the key concepts, formulae, and examples before starting your quiz.

🔑Concepts

Animals are living beings that need food, H2OH_2O (water), and shelter to survive.

Classification: Animals are grouped as Wild Animals (living in forests like lions and tigers) and Domestic Animals (living with humans).

Domestic Animals: These include Pet Animals (dogs, cats) for companionship and Farm Animals (cows, goats, hens) for use.

Beasts of Burden: Animals like bullocks, camels, and donkeys that carry heavy loads are called 'Beasts of Burden'.

Animal Products: We get milk (rich in CaCa), eggs, and meat from animals. We also get wool from sheep and silk from silkworms.

Shelters: Different animals live in different homes; for example, a horse lives in a stable, a dog in a kennel, and a bird in a nest.

Care for Animals: We should provide them with clean food, fresh H2OH_2O, and medical care when they are sick.

📐Formulae

H2O (Water for hydration)H_2O \text{ (Water for hydration)}

O2 (Oxygen for respiration)O_2 \text{ (Oxygen for respiration)}

Ca (Calcium from milk)Ca \text{ (Calcium from milk)}

💡Examples

Problem 1:

Identify the source of silk and explain why it is important.

Solution:

Silk is obtained from the cocoons of the silkworm.

Explanation:

The silkworm spins a thread-like substance around itself called a cocoon, which is processed to make silk fabric for clothing.

Problem 2:

Why are cows and goats called 'Milch' animals?

Solution:

They are called milch animals because they give us milk.

Explanation:

Milk is a complete food that provides essential nutrients like Calcium (CaCa) for strong bones and teeth.

Problem 3:

How do honeybees help us?

Solution:

Honeybees provide us with honey and wax.

Explanation:

Honeybees collect nectar from flowers and store it in beehives as honey, which is used as food and medicine.
