4th EVS NCERT Chapter 2

– Animals and Their Characteristics: Students should study the characteristics of animals such as their food habits, habitats, and reproductive methods. They should understand that animals with visible ears typically have hair on their bodies and give birth to young ones, while animals without visible ears lay eggs【4:0†source】.

– Recognizing Animals by Ears: Students should learn about different types of animal ears, such as fan-shaped ears, leaf-shaped ears, ears on the top of the head, and ears on both sides of the head. They should understand that ears help animals hear and that some animals have ears that are not visible but still present【4:2†source】.

– Patterns on Animal Skin: Students should be able to recognize animals by their skin patterns, which are due to the presence of hair on their skin. They can engage in activities to match animals with the patterns of their skin and observe how animals without hair would look different【4:2†source】.
