Bats.
2
Hi friends!
3
Today we are going to learn all about bats.
4
And if you want to read along with us, check out learnbright.org to find this lesson plan.
5
What are bats?
6
The only mammals that fly are bats, which is why some people mistake them for birds when they are in the sky.
7
But bats are more closely related to you than they are to a bird.
8
Plus, bats don't have feathers.
9
Instead, they have fur in various colors, such as gray, tan, brown, or black.
10
While bats live worldwide.
11
Most of them live in the tropics.
12
And most of them like to rest in dark places like caves, hollow trees, or even in attics.
13
But a few like to rest on rocks or trees.
14
There are over 1,300 species or types of bats.
15
Depending on the species, when their wings are spread open, they can measure from 6 inches to 5 feet across.
16
That's probably taller than you!
17
Their wings, which are their hands, are made of thin layers of bare skin, which join their long fingers together.
18
Bat wings stretch from the end of their long hands down to their legs.
19
They also have huge ears that point forward.
20
Large groups of bats are called a collective, cauldron, or colony, when they are swarming.
21
Bats prefer to live in groups and hang upside down by their feet while sleeping.
22
Scientists think sleeping upside down helps them escape predators because they can quickly drop into flight.
23
In addition, they are nocturnal and prefer to sleep during the day and hunt for food at night.
24
What do bats eat?
25
If you are a night flying insect, watch out for bats.
26
Some bats eat mice, reptiles, birds, and other smaller bats.
27
But most bats eat nothing but insects.
28
Small bats, the size of an adult thumb, can eat about 4 to 8 grams, that's about 2 grapes, of insects each night.
29
You might be thinking that's not a lot.
30
And when you take one million bats that eat insects every night, that's a lot of insects.
31
It's actually about a thousand metric tons.
32
Other bats eat small animals, like birds, frogs, mice, or fish.
33
Many bats prefer to eat fruit, nectar, and pollen from flowers.
34
But the vampire bat of South and Central America feeds on the blood of large birds and mammals.
35
Other interesting facts.
36
While they are flying, bats send out a cry from their mouths or noses that is so high-pitched people cannot hear it.
37
The sound helps them figure out the distance they are from particular objects and the size of the object.
38
The sound of the cry bounces off of objects and echoes back to the bat.
39
Using the sound waves, they can create a picture of exactly what's around them.
40
This is called echolocation.
41
Echolocation enables bats to avoid flying into objects in their path and to locate insects to eat.
42
When they find an insect, they trap it with their wings or tail and then reach over to put it in their mouth.
43
Unfortunately, chasing and eating insects using echolocation often makes their flight pattern look erratic or uneven rather than smooth like birds.
44
The saying, blind as a bat,
45
is inaccurate because bats have excellent eyesight and extraordinary hearing.
46
The bat is so unique that some ancient civilizations worshipped them.
47
For example, the Aztecs had many different gods, and their god of the dead was called Mclantacutli,
48
and he had a scrunched bat-like face with clawed hands and feet.
49
Why are bats important to the environment?
50
Just like bees and butterflies, Bats are pollinators as they fly from plant to plant in search of food.
51
Hundreds of plants, like bananas, mangoes, and avocados, rely on bats to pollinate them.
52
Bats also help spread seeds for nuts, figs, and cacao, the main ingredient in chocolate.
53
Without bats, we might not have delicious chocolate desserts.
54
They also play an extremely important, or essential, role in pest control.
55
By eating literally tons of insects a night, they help stop crop damage and decrease pesticide use.
56
But sadly, bats are declining across the globe.
57
People kill bats when they don't have to, because they don't understand their importance to the ecosystem.
58
And because of human progress and activity, bats are losing many of their caves for shelter, causing habitat loss.
59
And since 2006, 5 million bats have died have died from White Nose Syndrome disease.
60
But with knowledge and protection, we can help the numbers of bats soar again.
61
We have just learned some pretty bat-tastic facts.
62
Let's review.
63
Why is the bat population shrinking?
64
Where did you find that information?
65
The bat population is shrinking because people kill bats when they don't have to, and because of human progress and activity.
66
Why do scientists think that bats sleep upside down?
67
Scientists think sleeping upside down helps them escape predators because they can quickly drop into flight.
68
True or false?
69
Bats are nocturnal.
70
True!
71
Bats are nocturnal.
72
Fantastic work, friends!

इस वीडियो के साथ बोलने का अभ्यास करने का कारण क्या है?
बच्चों के लिए चमगादड़ों पर यह वीडियो एक अद्भुत संसाधन है जिसमें न केवल इन अद्वितीय प्राणियों की जानकारी दी गई है, बल्कि इसे सुनकर बोलने का अभ्यास करना भी एक मजेदार अनुभव है। अंग्रेजी शैडोइंग तकनीक का उपयोग करके, बच्चे इस वीडियो के साथ विचारों की स्पष्टता और आत्मविश्वास के साथ बोलने की क्षमता विकसित कर सकते हैं। जब आप वीडियो के संवादों का अनुसरण करते हैं, तो यह न केवल आपके वोकैबुलरी को बढ़ाएगा, बल्कि आपको सही उच्चारण और भावनात्मक अभिव्यक्ति को भी बेहतर करने में मदद करेगा।
संदर्भ में व्याकरण और अभिव्यक्तियाँ
- What are bats? - इस प्रश्नात्मक वाक्य का उपयोग ब्रह्मांड के ज्ञान को प्रस्तुत करने के लिए किया गया है। यह बच्चों को सवाल पूछने और जानकारी शेयर करने के लिए प्रेरित करता है।
- They prefer to live in groups - यहां ‘prefer to’ का प्रयोग विकल्प दिखाने के लिए किया गया है, जिससे बच्चों को अलग-अलग पसंद और प्राथमिकताओं को व्यक्त करना सिखाया जा सकता है।
- They have huge ears that point forward - इस वाक्य में गुण विशेषण का उपयोग बच्चों को विशेषताओं का वर्णन करने के लिए संलग्न करता है।
- Chasing and eating insects using echolocation - यह जटिल वाक्य उस क्रिया को दर्शाता है जिसमें बच्चों को क्रियाओं और उनके परिणामों के बीच संचार बनाना सिखाया जा सकता है।
सामान्य उच्चारण की कठिनाइयाँ
वीडियो में कुछ शब्दों का उच्चारण बच्चों के लिए चुनौतीपूर्ण हो सकता है, जैसे “echolocation”, “mammals”, और “nocturnal”। इन शब्दों में 'n' और 'l' ध्वनियों का सही उच्चारण करना आवश्यक है। संगीत की लय में बोलते समय बच्चों को अंग्रेजी उच्चारण में सुधार पर ध्यान केंद्रित करने के लिए प्रोत्साहित करें। Shadowspeak या shadow speech तकनीक का उपयोग करके, आप इन कठिन शब्दों को पुन: प्रस्तुत करके बच्चों को उच्चारण में सुधार में मदद कर सकते हैं।
इस वीडियो का व्याकरण
वक्ता जिन संरचनाओं का सबसे अधिक प्रयोग करता है, वीडियो के असली शब्दों के साथ:
| संरचना | वीडियो में |
|---|---|
| Passive voice be + past participle — ज़ोर इस पर कि क्या होता है, न कि कौन करता है | are spread · are made · are called |
| Present perfect have/has + past participle — बीता हुआ काम जिसका असर अभी भी है | have died · have just learned |
| Relative clauses who / which + उपवाक्य — व्यक्ति या वस्तु के बारे में अतिरिक्त जानकारी | bats, which is · wings, which are |
| “might / may” से संभावना might/may + क्रिया — जो हो सकता है पर पक्का नहीं | might be · might not have |
शैडोइंग तकनीक क्या है?
शैडोइंग (Shadowing) एक विज्ञान-समर्थित भाषा सीखने की तकनीक है जो मूल रूप से पेशेवर दुभाषिया प्रशिक्षण के लिए विकसित की गई थी। विधि सरल लेकिन शक्तिशाली है: आप मूल अंग्रेज़ी ऑडियो सुनते हैं और तुरंत इसे ज़ोर से दोहराते हैं — जैसे वक्ता की छाया 1-2 सेकंड की देरी से। शोध से पता चलता है कि यह उच्चारण सटीकता, स्वर, लय, जुड़ी हुई ध्वनियाँ, सुनने की समझ और बोलने की प्रवाहशीलता में काफ़ी सुधार करता है।
