Bones, Muscles & Postures Video Lecture | Science for Class 2

0:0:0: hello children
0:0:2: are you ready to discover the secrets of
0:0:5: your body
0:0:6: or have you ever wondered what makes up
0:0:10: the different parts of the body
0:0:13: and how they are connected
0:0:17: well get ready to explore the amazing
0:0:21: world of bonsai muscles
0:0:25: in this video
0:0:27: we are going to learn about
0:0:30: our bowls muscles and how we stand up
0:0:35: straight
0:0:36: our bones are like the sticks that make
0:0:40: up our bodies
0:0:41: they keep us upright
0:0:44: and help us move
0:0:47: our muscles are like rubber bands that
0:0:51: attach to our bones and make their names
0:0:56: and our posture is how we stand up
0:1:0: straight with our shoulders back and our
0:1:6: head held high so
0:1:9: are you excited to learn more about them
0:1:13: let's begin
0:1:16: children let's try something fun
0:1:21: touch the front part of your leg below
0:1:24: the knee and then touch the back of it
0:1:29: did you feel the difference
0:1:32: the hard part at the front is actually a
0:1:36: bone
0:1:37: while the soft part at the back is a
0:1:41: muscle
0:1:43: and winner bones and muscles work
0:1:47: together they help us do all sorts of
0:1:51: amazing things like running
0:1:55: jumping and even dancing
0:1:59: so let's give up pink round of applause
0:2:2: to our bones and muscles
0:2:6: they are the real superheroes that help
0:2:9: us move and grow
0:2:13: let us learn more about bones
0:2:17: first up let's talk about the hard outer
0:2:20: narrow of bones that is made of
0:2:23: calcium
0:2:25: this lid is super strong and helps to
0:2:29: protect our body from injuries
0:2:33: and did you know that all of our bones
0:2:37: are connected with each other through
0:2:40: special meeting points called joints
0:2:45: these joints allow us to bend and move
0:2:48: our body in all sorts of cool ways but
0:2:53: here's something rainy cool
0:2:56: when we are born we actually have around
0:3:1: 270 bones
0:3:3: however as we grow up
0:3:6: some of these bones fuse together so by
0:3:11: the time they become adults we only have
0:3:15: 206 bones left
0:3:18: now let us learn about the softer part
0:3:21: of our body which is the muscles
0:3:26: did you know that without muscles or
0:3:30: bones wouldn't be able to move at all
0:3:34: that's right
0:3:36: muscles are the magic ingredient that
0:3:40: makes all the movement in our body
0:3:43: possible
0:3:45: in fact muscles make up nearly half the
0:3:49: weight of our body
0:3:51: and guess what
0:3:54: we have more than 600 different muscles
0:3:59: in our body
0:4:2: from the tiny muscles inside our ears to
0:4:6: the big ones in our legs at Arms muscles
0:4:11: are all around us and here's something
0:4:15: really cool did you know that if we
0:4:19: blink our eyes we are actually using 200
0:4:23: muscles at the same time
0:4:26: and there are over 30 muscles in our
0:4:30: face alone that help us smile
0:4:34: from and yawn
0:4:38: but students have you ever touched your
0:4:42: nose or earlobe and wondered what is it
0:4:46: made of
0:4:48: these body parts are not bones or
0:4:52: muscles but something called
0:4:55: cartilage
0:4:57: Karthik H is like a soft flexible
0:5:1: cushion that can bend at move
0:5:6: but the real key to keeping our bodies
0:5:9: healthy and strong is eating a healthy
0:5:13: meal
0:5:14: exercising regularly and maintaining
0:5:18: good posture
0:5:21: exactly is posture
0:5:24: it's the way we sit
0:5:27: stand or leave around
0:5:31: when we sit we need to keep our backs
0:5:35: straight
0:5:36: against the back of the chair and our
0:5:40: seat flat on the ground
0:5:43: and when we stand we should keep our
0:5:46: shoulders and back
0:5:48: straight
0:5:50: even when we are walking we should keep
0:5:54: our bodies straight and swing our arms
0:5:57: from the shoulders
0:6:0: ym got posture so important
0:6:4: [Music]
0:6:5: well
0:6:6: if we sit or stand in the wrong posture
0:6:11: or bones and muscles will get used to
0:6:15: that shape and we will find it difficult
0:6:18: to sit or stand
0:6:20: straight in the future
0:6:24: so let's practice good posture every day
0:6:27: until it becomes a habit
0:6:31: and always remember
0:6:34: healthy food
0:6:36: exercise and proper posture are the keys
0:6:41: to keeping us strong at
0:6:43: fit
0:6:44: so with this we have learned about our
0:6:49: bones and muscles and the importance of
0:6:53: good posture
0:6:56: now children let me tell you an
0:6:58: interesting way to learn more with the
0:7:2: Adidas app
0:7:4: do you know that you can read the notes
0:7:6: of this chapter and can also take the
0:7:9: McQ test with the edurev app
0:7:13: and why should you do that
0:7:16: tests in the eduriff app are like a game
0:7:20: and this can help you become the topper
0:7:23: of your class
0:7:26: and not just science
0:7:28: you also get courses for EVS maths
0:7:34: English
0:7:35: Hindi and on other subjects in the
0:7:39: edurips app
0:7:42: go ahead and join the editor app to
0:7:45: learn in the most interesting way
