happy halloween my friends

[Laughter]

i know it's not halloween today

but can you guess what i'm going to talk

about

yes that's right

bones

zoom in

hey don't be scared that's not a ghost

that's just how your skeletal system

looks like come let's talk a little more

about the bones in your body

[Music]

let's start with the head

cranium

this is the cranium

it protects the brain from bumps

and knocks

[Music]

mandible

the lower part of the skull is called

the mandible

it is the largest and the strongest bone

of your face

scapula

it is a triangular shaped bone that is

protected by surrounding muscles

it is commonly called the shoulder blade

ribcage

the rib cage protects your heart and

lungs

it is actually very delicate and can be

damaged by accidents sports or even a

powerful sneeze

[Music]

the arm consists of three large bones

the humerus bone forms the upper arm

the radius and the ulna are the two

bones which form the lower arm

you have one radius and one ulna in each

arm the radius and ulna bones connect

between the elbow joint and the wrist

[Music]

your palm consists of three groups of

bones carpals metacarpals and

phallingers

fema the femur or thigh bone is the

longest heaviest and strongest bone in

the entire human body

all of the body's weight is supported by

the femurs during many activities such

as running

jumping

walking

and standing

patella the patella is also known as the

kneecap

it is a thick circular triangular bone

which covers and protects the surface of

the knee joint

fibula the fibula is the outer and

thinner bone of the lower leg

its main function is to provide

attachment for muscles however it

doesn't give much support and strength

to the leg

tibia the tibia is a large bone located

in the lower leg of the human body it is

also known as the shin bone and is the

strongest weight bearing bone

[Music]

just like your palm your foot also

consists of two groups of bones tassels

and metatarsals

trim your time

did you know that half of your body's

bones are in hands and feet

[Music]

and

an infant has 300 bones

whereas an adult has

206 bones

this is because some smaller bones fuse

together to form bigger bones

[Music]

okay kids got to go now

hey

hello friends

oh no

i guess that's a tsunami

come let me tell you all about it

zoom in

tsunamis are caused by sudden movements

of the ocean flow due to earthquakes

[Music]

landslides on the seafloor

land slumping into the ocean

large volcanic eruptions or

a meteorite crash on the ocean floor

when an earthquake

a landslide

or a volcanic eruption occurs on the sea

or ocean bed

a vertical jolt is created which

displaces the bed and causes extreme

tension in water

the water is pushed upwards but gravity

tries to pull it down

this causes an upsurge in the water

levels and the waves start moving away

from the point of tension

tsunamis are barely felt as a ripple on

the ocean surface as the water is quite

deep but

as and when those waves reach the land

the water becomes shallower and the

waves constantly increase in height

they hit the show and oh my cause a lot

of destruction

it is said the first wave of a tsunami

is not the strongest

but the successive waves are bigger and

stronger

oh

and tsunamis can travel at a speed of

about 500 miles per hour

which is almost as fast as a jet plane

and that's why tsunami waves are called

killer waves deadly isn't it

trivia time

did you know that a tsunami wave can be

less than 30 centimeters in height and

can pass off unnoticed

if you get stuck in a tsunami don't swim

because the currents will pull you in

the opposite direction

just hold on to a floating object and be

safe

so here's the deal go watch this video

to know more about earthquakes after all

that's one of the major causes of a

tsunami this is me

zooming out

[Music]

hello

it's quite windy today so i thought i'll

take a quick flight

it sure is windy

oh no it's a storm

you mean hurricane

pumpkin stop whatever just run

you mean fly oh forget it just calm down

oh okay well that reminds me that

today's topic is hurricane

zoom in

whoa

a hurricane is a huge storm that

generally forms over warm ocean waters

near the equator

the warm air above the ocean rises

upward

thus creating an area of low pressure

below

air from the surrounding areas push in

and try to fill the area with low air

pressure

which now becomes warm and moist and

rises too

as the moist air rises the surrounding

air again tries to fill in

and this process continues till the

water in the air forms clouds

soon the clouds and winds spin around

fueled by the ocean's heat and water

vapor

therefore hurricanes could also be

called giant engines that use warm and

moist air as their fuel

when we see from the top hurricanes can

be as huge as 300 miles wide

the center of the hurricane is called

the eye of the hurricane which is the

calmest part

the eye wall surrounds the eye where the

most damaging winds are found

it can range anywhere from 5 to 30 miles

then comes the rain bands which surround

the eye wall

these bands are a series of dense clouds

that give a pinwheel-like appearance to

the hurricane

which range from 50 to 300 miles

hurricanes are divided into five

categories

depending on the speed of their wind

here take a look

category three

four

and five are the most dangerous ones

trivia time

a huge hurricane can release energy

equivalent to 10 atomic bombs per second

hurricanes in the pacific ocean are

known as typhoons

so this is me zooming out

twinkle twinkle little star

oh i wonder what you are

like the baby star has slept but hey you

don't go to sleep because i'm here to

tell you about different types of stars

in space exciting isn't it

so tell me how many stars do you think

are there in the universe

oh come on you can do it

yes

well the answer

will be given at the end of this episode

zoom in

so there are different kinds of stars

the big ones even bigger than the sun

small ones some very odd ones and some

new ones

but did you know that they are

classified in groups

yes there are some specific types of

stars

the red dwarf stars they are relatively

smaller in size compared to the other

stars and therefore they burn at a lower

temperature which helps them have a long

sustainable life

some say a trillion years

nearly 70 percent of the stars in the

universe are red dwarf stars

but hey since they don't shine so bright

it gets difficult for humans to see them

with naked eyes

the yellow stars

these are medium-sized stars and

therefore burn at a medium temperature

there are yellow dwarf stars as well

that are not giant stars

our sun is one of them

these stars become quite large just

before they completely start running out

of fuel

the santu will completely lose its fuel

someday but don't worry that won't

happen before 5 billion years

blue giant stars

as the name suggests

these are big stars and hens burn at a

high temperature

leaving them with a short span of life

from 10 000

to 100 000 years

most of the stars you see in the sky are

blue giant stars

when these stars die unlike other stars

they don't shrink but explode

and this type of explosion illuminates

the entire sky

there are all sorts of other stars like

giant and super giant stars

which are extremely big

have the shortest life span and shine

the brightest

trim your time

every sun that you see in the sky is

actually bigger than the sun

proxima centauri a red dwarf star is the

nearest star to earth after the sun

[Music]

so

remember the question i asked you

how many stars do you think are there in

the universe

well the answer is

a hundred billion

isn't that a shocker

i can see stars in your eyes

so this is me zooming out

whoa

oops

i gotta be more careful

oh hello friends

i am in space today but you know why

to tell you about these magnificent

solar objects

comets

let's zoom in

[Applause]

comets are one of the most rare objects

in the solar system often known as the

dirt balls of the solar system

that's because they are made of dust and

ice

wrapping themselves around a small rocky

core

astronomers believe that comets are

leftovers from the beginning of the

solar system

but hey

they don't look like leftovers at all

they appear magical when they reflect

light from the sun

that's right

comets do not have their own light

they are reflectors of light

when a comet travels towards the sun the

radiation and heat cause solar winds

which often blow the gas and dust of the

comet and therefore it appears as if the

tail is behind the comet

and when the comet travels away from the

sun

the tail is formed in front of the comet

well

have you ever wondered where are comets

usually found yes yes they do orbit

around the sun mostly but they spend

billions of years in the kuiper belt or

in the wood clouds

the kuiper belt is found beyond the

orbit of neptune the wood clouds are

found in the outermost reaches of the

sky

and comets live here because it's cold

here

unfortunately they don't live long once

they enter the warmer part of the solar

system

traveling through the inner solar system

eventually kills them

and after several thousand years

they melt

all

trim your time

i know you wouldn't but if you ever plan

to go inside a comet you'll be hit by

microscopic pieces of dust

the name comment was given by aristotle

meaning hair of the head

[Music]

hey all my teeny tiny friends

the most famous comet the halley's

comment will appear in the sky in 2061

but don't worry you don't have to wait

that much to see me the next time

this is me zooming out

[Music]

oh

it's dark here

and i can't see you

oh wait

hey there

wonder what we do without lights right

so come on let's talk about light today

zoom in

light is a form of energy made of

photons

a photon is the smallest unit of visible

light

now you ask me how does light travel

well light is unique as it behaves both

like a particle and a wave that behaves

differently with different kinds of

matter

if light hits an object and passes

through it

that object is known as a transparent

object

let's do one thing take a glass of water

and switch on a torch

see the light passing through

well

this proves that water is transparent

there are certain objects through which

light cannot pass and it changes its

path after hitting the object

these objects are called opaque objects

such as wood

the mobile you're using right now and

you as well

yeah

humans are opaque as well

some objects allow light to pass through

them partially and they are known as

translucent objects such as plastic

butter paper

and frosted glass

and do you know what travels the fastest

no not a space rocket

well

it's light in vacuum where there's no

obstacle

light travels at a speed of more than

0.1 million miles per second

okay so the distance between the sun and

earth is 93 million miles

but it takes only eight minutes for

light to reach the earth that's a

whopping speed isn't it

when light travels through different

mediums it slows down and sometimes

bends and this bending of light is known

as refraction

take a beaker filled with water and

place a pencil in it

now look carefully

do you see a bend in the pencil

[Music]

no no the pencil didn't bend

the light rays just got refracted

that's why you see the pencil bent

trim your time

did you know that humans are

bioluminescent which means that they

emit light

but their glow is one thousand times

weaker than what the naked eye can

register

light takes approximately 1.2 seconds to

reach the moon from the earth

so friends did i not light up your

tickling brain cells today

hi friends did you just see that mighty

beast

well

that's a shark

hey that's not done i'm no beast dr

bynox i mean look at my voice and look

at me i'm a tiny little being

oh i'm sorry mr shark i was kidding i

know you are not a beast but a lot of

people think you are so why don't you

clear that myth today my friend

that's a good idea

friends wanna bust some myths about

sharks today i know you do

come zoom in

it is said that most sharks are

man-eaters and they deliberately hunt

humans

which is not completely true

mook sharks tend to eat fish or

invertebrates such as squids or clams

if sharks happen to kill humans it's

mostly because of mistaken identity

sharks mostly mistake humans to be some

fish or another animal

i'm sure you would have heard the sharks

have lots and lots of sharp pointed

teeth

well

not all sharks have icicle-like thief

the basking shark has tiny teeth

which it does not even use for hunting

or feeding and the horn shark has

molar-like teeth

which is used to crush its hard-shed

prey

it is often believed that sharks are

indiscriminate killers

but most of the times they are victims

of massive hunting for their fins which

is made into shark soups

oh

people claim that shark fins are tasty

and have a lot of nutritional value

which is absolutely untrue

shark fins are tasteless with absolutely

no nutritional value

and if you think sharks have no

predators

you're wrong

humans are their biggest predators

if you actually look at numbers you'll

be surprised to know that sharks kill

approximately six humans in one year

whereas humans kill about 100 billion

now

that's called being indiscriminate

sharks also help a lot in maintaining

the balance of life

since they are the top of the food chain

they keep the marine population in check

trivia time

there are approximately 500 species of

shark out of which white sharks tiger

sharks and bull sharks are the most

dangerous ones

sharks have an extremely strong sense of

smell almost two-thirds of its brain is

dedicated to the sense of smell

so friends now you know that sharks are

a lot more than their scary teeth

you're right dr biodox thanks for

clearing the silly myths about me i owe

you one

oh come on let's drink some soup

uh oh really soup

not shark fin soup

oh there you go

so this is me zooming out

hello kids

won't it be great if we could just pack

up bags and keep flying from place to

place

hey but you can't do that because you

don't have wings like me

oh yes you're right but there's one

major difference between you and my

friends out there and that is

you're a migratory bird silly

oh

oops why didn't that strike me

doesn't matter you go take your flight

and i'll tell my friends all about birds

like you

oh i feel so special dr binox

come friends let's know more about

migratory birds

zoom in

migratory birds are those birds that

travel from one place to another at

regular intervals over long distances

and they migrate to escape the cold

harsh winter weather in search of food

and a warm cozy shelter

there are various types of migratory

birds

resident birds pigeons and doves are

good examples

these birds just don't migrate they are

able to find food and a warm shelter

where they are staying

we might not travel a lot dr binocks but

we do spread love all around from place

to place

short distant migrants

robins are short distant migrants

as the name suggests

these birds move only a short distance

from lower elevations to

mountainside hey

but don't you mistake me for a

nightingale i might look like one but

i'm not okay oh my friends won't they

are very smart aren't you guys

distant migrants

these birds travel over distances that

cover several states

they don't really travel a lot but not

that they won't travel less isn't it mr

blue jay hmm you seem to know me quite

well dr bynox but there's one more

secret about me wanna know

sure tell us

we are all waiting

hmm i'm quite mischievous dr binox

because i hunt more than i can eat

long distant migrants

these birds travel typically from united

states and canada to wintering grounds

in central and south america the arctic

turn is an example of long-distance

migrants and i am the record holder for

covering the longest distance of 44 000

miles oh my that's huge

just to let you know the circumference

of the earth is approximately 29 000

miles

so imagine

how much these birds travel

trim your time

before migrating many birds enter a

state of hyperphasia where the hormone

levels compel them to drastically

increase their body weight to stow fat

to use as energy while traveling

and some birds also have the ability to

sense the earth's magnetic field to help

them navigate

so i need to travel now wait till i come

back next

i feel plants are the nicest beings on

this planet

they never harm anyone rather they get

eaten all the time

oops

i guess some eat too

and that's why i'm here today to tell

you about plants that eat meat

come with me

zoom in

plants that capture preys such as

insects spiders mites and eat meat for

their survival are known as

insectivorous or carnivorous plants

most of the carnivorous plants live in

wet buggy areas where the soil doesn't

have much nutrients

they derive their nutrients from their

preys

and whatever little nutrients available

to them through soil

they have a strong digestive system

which helps break down complex food

items

the different types of carnivorous

plants are

pitfall traps

popularly known as pitcher plants they

are pitcher plants because they look

like pitcher-shaped vessels

filled with fluid

the insect is lowered by the syrupy

fluid and just when they come to drink

it they get drowned some pitcher plants

have a lid on them to trap their preys

fly paper traps

some fly paper traps have leaves covered

with a sticky substance on which the

prey gets caught

these plants also digest their preys

through their leaves

other kind of fly paper traps use

tentacle-like stalks covered with glands

to trap and digest insects

their stalks have digestive soup on them

to absorb the nutrients

snap traps

venus fly trap is the most popular snap

trap

here the plant has mouth-like leaves

that literally snap shut when an insect

or spider lands on it

there are some snap traps that are found

under water

and they are known as water wheel plants

they do the same thing but under water

bladder traps

plants of this kind work in the most

interesting way

where there are sacks on the plant known

as bladders

that create vacuum and suck the insect

to digest it later

lobster pot traps

the plant first lures its insects with

its sweet smelling nectar

once the insect is trapped inside

it sees light shining through the leaves

which looks like exits

to escape the insect travels towards the

light which is nothing but another trap

this is the plant's way of actually

misdirecting the insect to the inside of

the pitcher where it is caught and eaten

by the digestive liquids

trim your time

some pitcher plants are so large they

can catch and consume rats

and frogs

some carnivorous plants reflect

ultraviolet light to attract their

praise

hey don't go there

wait i'll help you

let go

[Applause]

[Music]

so this is me zooming out

who's that hey you're disturbing the air

around us

sorry i know i'm farting a lot today

oops

hmm

guess you took in a lot of carbon

dioxide for lunch yesterday

oh yeah could be

did you just hear them friends oh no not

their thoughts

and that reminds me that i need to tell

you about the process of excretion in

plants

come with me

zoom in

just like humans plants to feel the need

to remove all sorts of waste material

from their bodies however plants have a

much simpler process of excretion

hey did you know that plants sweat well

yes

just like humans have sweat glands

plants have small openings under their

leaves

called stomata

that release water and oxygen

just how the pose of your body release

sweat

but

their waste material is a lot more

useful than us

[Music]

plants also release waste by

accumulating it in the vacuoles of aging

leave cells the leaves then fall off

eventually removing the waste material

this process is known as abscission

don't you sometimes have dry skin that

eventually falls off

yep kind the same

have you noticed leaves changing their

color in autumn

this happens mostly because of the waste

pigments that start getting stored

inside the leaves

see the sticky fluid

well

this is another kind of waste produced

by the plants

which is often oozed out from the bark

of trees apart from the sticky fluid

there are other waste products like

resins

gums

and latex

but hey

you got to be careful because sometimes

these products can be poisonous

but most of the other times they are

quite useful for example latex is used

to produce gloves and clothing

trim your

time the bark of a willow tree produces

a chemical that helps in the making of

aspirin

a medicine for pain and fever

oak leaves turn brown due to the waste

material in them

so friends plant more and more trees

because they are the reason why you can

breathe

[Music]

breathe in breathing out that's what i

say throughout breathe in

breathing out that's what i say

throughout

[Music]

oh so you've been watching me work out

eh

rather breathe in and breathe out

oh this is tiring

so anyways

why don't we talk about breathing today

still can't get a hint

well today we talk about the human

respiratory system zoom in

all right do this right now i'm watching

you

just start running wherever you are run

run run run run run

now stop

isn't your breathing heavy

well that's because right now your body

needs more oxygen to breathe and you get

oxygen from the air around you

without oxygen you'd be like a car

without fuel

a waterless spool

and wouldn't that be uncool

one of the major reasons why you're

alive is

oxygen

so

take a deep breath in

[Music]

when you breathe in you take an oxygen

present in the air the air then passes

through your nostrils

there are tiny hair present in your

nostrils that obstruct

[Music]

all the dust particles

then the air travels to the windpipe

also called the trachea which filters

the air inhaled

the trachea branches out to two tubes

called bronchi

where tiny hair called cilia move back

and forth moving the mucus inside

the mucus is a sticky substance that

collects germs and other particles that

might harm the lungs

the bronchi then carry air into each

lung

the right lung has three lobes whereas

the left lung has two lobes

the left lung is slightly smaller in

size to give space to the heart

these lobes are filled with small and

spongy air sacs called alveoli

where the exchange of oxygen and carbon

dioxide happens

it is here the blood picks up oxygen and

lets go of carbon dioxide

just beneath the lungs there is a

dome-shaped muscle called diaphragm

that contracts when you breathe in and

expands when you breathe out

it also separates the chest cavity from

the abdominal cavity

trivia time

[Music]

the lungs are the only organs that can

float on water

a person breathes approximately 20 000

times in one day

so friends

didn't you just gasp and grasp all the

facts

this is me

zooming out
