These resources include detailed notes, interactive exercises, and practical examples that cover the entire spectrum of key concepts. From fundamental principles of recognizing different animals by their ears, to understanding their unique characteristics, the materials encourage observation and critical thinking. Through engaging activities like identifying animals based on ear shapes and sizes, students learn about the diversity of animal species. The resources also promote awareness of how these features help animals adapt to their environments.

The concept of “Ear to Ear” in Class 4 EVS delves into the foundational principles of life by exploring the essential characteristics that define animal diversity through the study of their ears. It encourages students to observe and appreciate how different animals have varied ear shapes, sizes, and positions, which are crucial for their survival and adaptation. This lesson highlights the role of ears in sensing the environment, communication, and protection. By understanding these features, students gain insight into the broader themes of evolution and biodiversity, fostering a deeper connection with the animal kingdom and nature’s complexity.

Objectives of Learning Chapter 2: “Ear to Ear” in Class 4 EVS

There are various objectives of learning the chapter “Ear to Ear”. These include-

• Identify and Recognize Animal Diversity:
  The chapter “Ear to Ear” will help students identify and classify animals by their ear shapes, sizes, and unique features, introducing them to the vast diversity in the animal kingdom.
• Develop Observation Skills:
  The “Ear to Ear” chapter from class 4 EVS encourages keen observation as students learn to distinguish animals based on visible and hidden traits, like ears and skin patterns, fostering closer attention to detail.
• Explore Animal Adaptations:
  By studying “Ear to Ear,” students understand how different ear structures help animals sense their surroundings, communicate, and protect themselves, adapting uniquely to their habitats.
• Understand Sensory Organs and Survival:
  “Ear to Ear” provides insight into how animals use sensory organs, particularly ears, to survive, interact, and thrive in their ecosystems.
• Appreciate Biodiversity:
  This chapter, “Ear to Ear,” emphasizes the diversity among animal species and encourages appreciation for the unique adaptations that each animal possesses.
• Connect Physical Features with Ecosystems:
  “Ear to Ear” allows students to explore the relationship between animals’ physical characteristics, such as ear structures, and the ecosystems they inhabit, building a foundation in environmental science.
• Encourage Critical Thinking and Curiosity:
  Through the engaging activities in “Ear to Ear,” students are inspired to think critically about the natural world and ask questions about the role of physical traits in animal adaptation and survival.

These objectives aim to provide Class 4 students with a well-rounded understanding of animal characteristics, the role of adaptation, and the importance of biodiversity.

Who Has Got My Ears?

In this section, we explore the concept of identifying animals based on their ears. The artist has drawn animals with incorrect ears! Let’s help the animals get their correct ears by filling the table below.

Different Animals Have Different Kinds of Ears

Among the given animals as mentioned in the chapter Ear to Ear, which ones have visible ears, and which do not? Let’s categorize them in the table.

Visible and Hidden Ears:

Do animals without visible ears really lack ears? No! Even though we cannot see the ears of some animals, they still have them. For example, birds have tiny holes on both sides of their heads, usually covered by feathers. Similarly, lizards and crocodiles also have ears, but they are not easily visible. 

Recognizing Animals by Their Skin

Just as we can identify animals by their ears, we can also recognize them by their skin patterns as mentioned in the chapter Ear To Ear. Let’s match the animals with the patterns of their skin.

Match the Animals with Their Skin Patterns

• The different patterns on animals are due to the hair on their skin. Imagine how an animal would look without hair—there would be no patterns! 

Ears and Skin: Observation

In this activity, we categorize animals based on whether we can see their ears or not and whether they have hair or feathers on their skin.

Do cows and buffaloes have visible hair? Yes, but you might need to get closer to notice it. Even elephants, which seem hairless from a distance, have hair on their skin! 

Egg Layers or Baby Givers?

Let’s classify the animals based on whether they lay eggs or give birth to babies.

Animal Classifications:

From this, we observe that animals whose ears are visible usually give birth to babies and have hair on their bodies. On the other hand, animals whose ears are not visible often lay eggs and do not have hair.

Observing Animals Around Us

Have you ever observed small animals around your house or school? Write down the names of these animals and find out more about them. If you or someone you know has a pet, answer the following questions:

• What animal is it?
• Does it have a name? Who named it?
• What does it like to eat?
• How many times a day does it get food?
• Does it have hair or feathers?
• Does it lay eggs or give birth to babies?

Draw a picture of the pet and give it a name of your choice! 

Creative Activities

Color the Animal

In this activity, you are asked to color specific parts of an animal in the picture. Once completed, find out the name of the animal by following the pattern! 

Learning About Dinosaurs

Class 4 EVS chapter 2 Ear To Ear Also covers that millions of years ago, dinosaurs roamed the Earth. While they are extinct today, we can still learn about them through books, photos, and films. Have you seen any animals that resemble dinosaurs? Ask your elders about them and share your findings with your friends. 

Our National Animal

Do you know which animal is our national animal? It is the Tiger! Tigers are found in forests and their numbers are decreasing in India. Discuss with your classmates why this is happening and what we can do to protect them. 

Make Your Bird

In this fun activity, use colored paper to make a bird. The paper should have different colors on both sides to make your creation look more vibrant!

Here’s how you can complete the “Make Your Own Bird” activity given in the chapter Ear to Ear Gather the materials below and follow the steps to create a colorful paper bird.

Materials Needed:

• Colored paper (different colors on both sides)
• Scissors
• Glue or tape
• Markers or crayons (optional, for additional decoration)
• Googly eyes (optional)

Steps:

1. Choose Your Paper
   Select a piece of colored paper with different colors on each side. This will give your bird a vibrant look!
2. Create the Body
   • Cut an oval or circular shape from the paper for the bird’s body.
   • Fold the shape in half to give the bird a bit of dimension.
3. Make the Wings
   • Cut two smaller ovals (or leaf shapes) from the paper for the wings.
   • Glue or tape the wings to each side of the bird’s body. If you want, angle them slightly to look as if the bird is in motion.
4. Add the Beak
   • Cut a small triangle from the paper and fold it in half.
   • Glue the folded edge of the triangle onto the bird’s face to create a beak.
5. Attach Eyes
   • Draw eyes on each side of the bird’s head with markers, or glue on googly eyes for a fun touch.
6. Add a Tail (Optional)
