7. Now can you guess why the ants behaved like that when you blocked their path?

2. How do you feel when you walk near a heap of garbage? Think of the children who spend the whole day picking things from such garbage.

THINK

1. Is there some link between the size of animals’ ears and their hearing?

Ans: Yes, animals with larger ears often have better hearing compared to animals with smaller ears. This is because larger ears can capture more sound waves and funnel them into the ear canal, allowing for enhanced detection of faint sounds and improved sensitivity to various frequencies.

TRY THIS

1. For this activity find a quiet place in your school. Tell one of your friends to stand at a short distance and ask him to say something softly. The rest of you should listen carefully. Then all of you put your hands behind your ears, as shown in the below picture. Let the same child say something again as softly as before. In which case was the sound sharper? Ask your friends too.

Ans: Placing your hands behind your ears can make sounds seem sharper or louder. This is because the hands act like a funnel, directing more sound waves into your ear canal.

2. Put your hands over your ears and say something. Can you hear your own voice?

Ans: Yes.

3. Sit near a desk. Tap the desk once with your hand. Listen carefully. Now put your ear on the desk as shown in the picture. Tap on the desk once again with your hand. Listen again. Was there any difference in the sound of the tap?

Ans: When you place your ear on a desk, the sound becomes clearer and sharper. This is because the hard surface of the desk conducts sound vibrations effectively.

WRITE

1. Can you understand the sounds of some animals? Which animals?

Ans: Yes, I can recognize the sounds that animals like dogs, cats, sheep, pigs, horses, and others make.

2. Do some animals understand your language? Which ones?

Ans: Yes, some pets such as dogs, cats, parrots, and cows can understand the words we say.

SAY IT WITH SOUNDS

1. Just like birds and dolphins you can also make your own language of sounds for giving messages. Remember you have to talk to your friends with only sounds and no words. How and when will you need to give an alarm call? For example, when the teacher is coming to the classroom!

Ans: To wake up our friends when the teacher is coming to the classroom, we can make sounds like ping-ping or tik-tik. Everyone can hear these sounds and know it's time to wake up.

SLEEPING - WAKING

1. Have you noticed that during the cold season you cannot see any lizard in the house? Where do you think they have gone?

Ans: Yes, I've seen that in winter, we don't see any lizards in the house because they probably moved to a warmer place to stay safe.

2. How will you show the clock for a house-lizard in winters?

Ans: The colored part indicates the sleeping time for lizards during winter.

3. Given here is the sleeping time of some animals. Write below each picture for how many hours a day that animal sleeps.

Ans: Cow sleeps for four hours a day.

Python sleeps for eighteen hours a day.

Giraffe sleeps for two hours a day.

Cat sleeps for twelve hours a day.

4. When you see different animals, do you have any questions about them? Make a list of ten such questions.

Ans: Yes. Some of the questions 

• How do they communicate with each other?

• What do they eat, and how do they find their food?

• Where do they live, and how do they build their homes?

• How do they protect themselves from predators?

• What is their lifespan, and how do they reproduce?

• How do they adapt to changes in its environment?

• What are the daily habits or routines of (specific animal)?

• How does it use its senses to navigate its surroundings?

• How do they contribute to its ecosystem?

• Are there any unique behaviors or abilities that have evolved?

5. The tiger is one of the most alert animals. And yet, today tigers are in danger. What do you think are some of the dangers to tigers in the jungle?

Ans: Even today, tigers in the jungle face several dangers. The primary threat comes from hunters who kill them for their skin. Additionally, lions pose a threat to tigers because they are stronger. Tigers also face dangers such as forest fires, habitat destruction due to deforestation, and human activities.

6. Can human beings also be a threat to animals? How?

Ans: Yes, humans pose a significant threat to animals. The growing human population has resulted in widespread deforestation, which diminishes natural habitats for wildlife. Sadly, humans also hunt animals for their valuable parts; deer for their skin, elephants for their tusks, rhinos for their horns, and tigers for their skin are just a few examples. These activities endanger many species and disrupt ecosystems worldwide.

FIND OUT

1. Where are other such National Parks in India?

• Ranthambore National Park

WHAT WE HAVE LEARNT

1. Have you noticed that sometimes singers put their hand on their ear when they sing? Why do you think they may be doing this?

Ans: Yes, I've noticed that singers sometimes place their hands on their ears to block out external noise and hear their own voices more clearly.

2. Give examples of animals that may have a very strong sense of sight, hearing or smell.

Ans: 

Sight:

• Eagle: Known for its exceptional vision, eagles can spot prey from very high altitudes.

• Owl: Owls have excellent night vision and can see in low-light conditions.

Hearing:

• Bat: Bats rely heavily on echolocation, using sound waves to navigate and locate prey in the dark.

• Elephant: Elephants can hear infrasound, very low-frequency sounds that travel long distances, helping them communicate over large areas.

Smell:

• Dog: Dogs have an incredible sense of smell, which they use for tracking, detecting explosives and drugs, and even identifying medical conditions in humans.

• Bear: Bears have a strong sense of smell that helps them locate food sources like berries, fish, and carcasses from long distances.
