Ear to Ear
Class 4 · Environmental Studies
3 ideas in Class 4 Environmental Studies, explained in plain words, with games and quizzes to practise.
Visible and Hidden Ears
Part of: Animal ears
Some animals have outer ears that are easy to notice. A bird's ears are not seen like a cat's ears; small openings on the sides of its head are usually covered by feathers. Tiny openings on a lizard's head are also ears, and a crocodile's ears can be hard to notice.
Why it matters. A body part may be hard to see without being absent. Looking carefully helps children classify animals without assuming that every animal's body is built like a familiar pet's.
Try it in two minutes
- Look at pictures of a cat, a bird and a lizard.
- Ask which animal has an outer ear that stands out clearly.
- Look for the small openings described for birds and lizards.
- Discuss why not seeing an outer ear does not prove that an animal cannot hear.
Try at home. Choose three animal pictures and sort them into visible outer ears and ears that are difficult to see.
Hair, Feathers and Skin Patterns
Part of: Animal ears
Animals can have different coverings. Birds have feathers, while many familiar animals have hair on their skin. The patterns shown on animal skins are linked to hair. Hair may be difficult to notice on a cow or buffalo from far away, and an elephant also has hair even when its skin looks smooth.
Why it matters. A close look can reveal features that are easy to miss from a distance. Comparing coverings helps children describe animals more carefully than simply judging by colour or size.
Try it in two minutes
- Look at pictures of a bird, cow and elephant.
- Ask which animal has feathers and which have hair on their skin.
- Compare the animal patterns shown in the chapter.
- Discuss why getting closer can help someone notice fine hair.
Try at home. Sort animal pictures into feather-covered and hair-covered groups, then describe one visible pattern.
Eggs, Babies and Animal Groups
Part of: Animal ears
Animals do not all have young in the same way. In the examples grouped in this chapter, a hen lays eggs, while a cow gives birth to babies. The animal list lets children compare reproduction with other visible features, such as feathers, hair and outer ears. These are patterns in the examples, not a rule that every animal can be classified by one feature alone.
Why it matters. Sorting examples helps children notice similarities among animals while avoiding a quick guess from just one clue. Looking at more than one feature makes a classification more careful.
Try it in two minutes
- Name a hen and a cow and ask how each has its young.
- Place pictures of a sparrow, duck and buffalo into two groups by how they have young.
- Compare one animal's body covering with its group.
- Ask why one clue alone may not describe every animal.
Try at home. Choose four animal pictures from the chapter and make two groups: animals that lay eggs and animals that give birth to babies.
