Shadow Story Video Lecture | Mathematics for Class 2 (Joyful-Mathematics)

0:0:0: hello
0:0:1: students today we are going to study
0:0:3: chapter 4 of Class 2 which is Shadow
0:0:7: story so children let's start look at
0:0:12: this
0:0:13: video this is a shadow play known as to
0:0:16: Glo see how people behind the curtains
0:0:19: are making Shadows of RAM and telling us
0:0:22: the story of
0:0:23: ramayan beautiful isn't it you can make
0:0:27: shadows too with your hands
0:0:30: let's make some Shadows of animals with
0:0:33: our hands turn off all the lights of
0:0:36: your room use a torch and your hands and
0:0:39: follow the
0:0:40: video Let's Make a dog make your left
0:0:44: hand like this now put your right hand
0:0:48: on top of it like
0:0:55: this see it's a
0:0:57: dog now let's make a a deer make your
0:1:2: right hand like this this will be the
0:1:5: horns of the deer now put your left hand
0:1:8: like this under your right hand to make
0:1:10: deer's
0:1:12: head
0:1:14: great now where else have you seen your
0:1:18: Shadow when you are coming back home
0:1:20: from school in the
0:1:22: afternoon You See Your Shadow on the
0:1:25: road you also see the shadows of trees
0:1:28: and other things but the Shadows vanish
0:1:31: as soon as we enter our home let's see
0:1:35: why we see a shadow and why it
0:1:38: vanishes I have a cone here let's use a
0:1:42: torch and put light on it from the front
0:1:44: of the cone see it has a long and
0:1:47: triangular
0:1:48: Shadow now let's move the torch a bit up
0:1:53: the shadow is getting
0:1:55: smaller let's move the torch more up the
0:1:59: torch is now now on the top of the cone
0:2:2: see the cone has a very small Shadow now
0:2:6: let's look at Shadows of other shapes as
0:2:9: well look at this shadow of a
0:2:12: sphere how round it is look at this
0:2:16: shadow of a
0:2:17: cylinder and this cube when we put the
0:2:21: torch in the front of these shapes the
0:2:23: Shadows are the
0:2:25: longest but when we put the torch on top
0:2:28: of them the shadow gets
0:2:30: smaller this is the reason why we have a
0:2:33: very small shadow in the middle of the
0:2:36: day because the sun is on top of our
0:2:39: heads and we have a long shadow in the
0:2:42: evening when we go to play with our
0:2:45: friends because the sun is lower now and
0:2:49: the shadow vanishes when we are in the
0:2:51: dark because there is no sun or
0:2:54: light notice how the Shadows are flat
0:2:57: but the shape is not flat
0:3:0: see they are
0:3:1: solid we can also draw these flat shapes
0:3:5: by real
0:3:6: objects by
0:3:8: tracing let's do a fun
0:3:11: activity let's trace this glass on a
0:3:14: paper
0:3:15: see we get a circle after tracing a
0:3:19: glass now let's trace this crayon box
0:3:23: and see what shape we get we get a
0:3:26: rectangle see this brings us to the end
0:3:31: of this video we hope that you have
0:3:34: understood the chapter Shadow
0:3:36: story you can view the ncer solution of
0:3:40: this chapter on
0:3:42: adve you can learn with chapter notes
0:3:45: watch video lectures and solve ncer
0:3:48: based McQ tests of this chapter on
0:3:52: urv and that's not all you also get
0:3:55: amazing courses for Class 2 and much
0:3:58: more for your class 2 preparation
0:4:1: thank you
