00:43	units of time . But before we start learning ,
00:48	we have some brand new kids comments . This first
00:50	one is from Nora and Boas , who live in
00:53	Hampton , Virginia , who share . We really enjoyed

02:36	. Be sure and watch this video to the end
02:39	to learn how you too , can be featured on
02:42	one of our videos . Just like Nora Boas .
02:44	Rishi , Miss Jessica's class in Ms Commodities class were
02:47	featured on this video . So as we mentioned earlier
02:54	today , we are going to learn about the units
02:57	of time . Mhm . There are three main units
03:03	of time in a day seconds , minutes and hours
03:08	. A second is the smallest unit of time .
03:13	It's so tiny a minute is a lot bigger than
03:17	a second , and then an hour is even bigger
03:21	. An hour is the biggest unit of time in
03:24	a day . We're going to look at each of
03:29	these individually , Okay ? It is going to be
03:34	a great time . It's funny , right ? First
03:44	, we're gonna learn about seconds . Mm . A
03:50	second is the smallest unit of time . It's extremely
03:54	short now , a fair warning to you . You're
03:57	about to see some very cute animals that are going
03:59	to help us understand just how long a second is
04:05	. Mhm . Hey , what did we say ?
04:07	We warned you the time that it takes this cute
04:12	little dog to jump is a second . It's just
04:16	like a moment . Boom . The dog jump swooped
04:20	in the air for a second down . And you
04:23	see how this dog is jumping over that pole ?
04:25	Really cool . Great dog . It takes just a
04:28	second to jump . That's the second . That's the
04:33	sound . That's the second . Okay , Another cute
04:38	animal . This is a cat and this cat is
04:41	blinking . The time it takes to blink is a
04:45	second not just for cats , for humans . Why
04:47	don't you give it a try ? Go ahead and
04:50	blink . Yeah , that's the second . Can you
04:53	blink again ? That's another second . Can you blink
04:57	again ? That's a second . It's so short .
05:01	It's such a short amount of time . Could you
05:03	blink again ? Okay , that will be the last
05:05	time . Okay . It's a second . It's a
05:07	second to blink . Oh , who doesn't love a
05:13	good seal ? Here's the seal in the water Sang
05:18	high by waving that wave takes just a second .
05:23	Did you know when we say hi That takes a
05:26	second to Why don't we give that a try ?
05:29	Say the word high . Hi . Hi . That's
05:35	a second high . That's a second high . Now
05:39	I don't want you annoy people around you , but
05:42	I want you to understand it just takes a second
05:44	to say hi or to waive . Waving usually takes
05:49	just a second . Yeah , on a clock seconds
05:56	are shown with the thinnest line . It's also the
05:59	line that moves the fastest because seconds are the shortest
06:03	period of time . Now you might not realize this
06:10	, but every unit of time has an abbreviation .
06:14	An abbreviation is a short form of a word and
06:19	seconds actually have two abbreviations . Mhm . Yeah .
06:25	The abbreviations of seconds are sec or just the letter
06:31	s . Here's an example . You could say one
06:35	second or if you wanted to write it with an
06:38	abbreviation , you could write one sec or just one
06:43	s . Here's another example . Five seconds could be
06:50	written five sec or five s . Now , you
06:54	don't always have to do that . You don't always
06:56	have to use an abbreviation . But if you want
06:59	to abbreviate and make seconds shorter , you can just
07:02	write five sec or five s . The final example
07:10	10 seconds can be written 10 sec or 10 s
07:15	. Sec or s are abbreviations of the word seconds
07:22	. Seconds are the shortest unit of time . Yeah
07:30	. Next , we're gonna talk about minutes . Yeah
07:34	, a minute is the next biggest unit of time
07:38	after seconds . Now , how much bigger is a
07:41	minute than a second ? Well , believe it or
07:46	not , a minute is 60 seconds . 60 seconds
07:51	. Sixties a lot . Now you might be wondering
07:53	how much is 60 ? I'd love to see that
07:56	. Well , look at this a lot . It's
08:01	a lot . Sixties . A lot . A minute
08:04	is 60 seconds Here's an example of something that takes
08:11	about a minute . A little girl blowing Bubbles takes
08:14	about a minute , about 60 seconds . For a
08:17	while . She'll blow these bubbles and then she'll be
08:20	done . She might spend a couple minutes where she
08:23	might just spend a minute . It's not too long
08:26	, but it's not too sure . It's a minute
08:30	. This little boy's tired . Maybe he played for
08:33	a long time , and he just wants to sit
08:35	down for a minute . This is something that might
08:37	take a minute , sitting down and just taking a
08:40	break . It wouldn't be enough of a break to
08:43	just take a second break , but a minute can
08:48	help him . Rest . A minute is 60 seconds
08:51	. It's enough time to take a break , to
08:53	breathe for a while and then to go back to
08:56	playing . Here's our final example of a minute .
09:00	A little girl who's cuddling with her teddy bear .
09:04	Maybe she named him Mr Perkins , and maybe she'll
09:07	give him hugs every once in a while . But
09:09	now she's taking her time to cuddle him for 60
09:14	seconds a minute . Maybe she'll spend about a minute
09:17	. A second would just be too short to hug
09:20	, Mr Perkins , but cuddling for a minute .
09:23	She would take a minute to do that on a
09:29	clock . Minutes are shown with the longest line .
09:33	So when you look at a clock the longest line
09:36	called a hand on a clock that longest hand measures
09:40	the minutes . Now remember , every unit of time
09:46	has an abbreviation . And remember , an abbreviation is
09:50	just a short form of a word . The abbreviation
09:58	of minutes is men M I N men . Here's
10:03	an example . One minute would be abbreviated one men
10:09	, Look at this . 15 minutes would be abbreviated
10:14	. Five men , 10 minutes would be abbreviated .
10:23	10 men a minute is the next biggest unit of
10:29	time after seconds . The last unit of time we're
10:36	looking at today are ours . Ours are the largest
10:41	units of time in the day . In fact ,
10:44	in a day there's only 24 of them , not
10:47	many at all . Okay , so how long is
10:53	an hour , exactly ? Well , an hour is
10:55	60 minutes . Do you remember how big the number
10:59	60 is , right ? Oh , lots of minutes
11:04	. 60 minutes an hour is 60 minutes . Remember
11:08	, a minute is 60 seconds . So it's a
11:11	lot of time . Here's an example of an hour
11:15	. This girl playing out in the snow . This
11:18	girl would want to play out in the snow for
11:20	like an hour . Right ? 60 minutes one minute
11:23	wouldn't be enough playing out in the snow in one
11:26	second . Well , one second is like high ,
11:29	and that's the second . Remember , so an hour
11:32	, 60 minutes . It's a good long time to
11:34	play out in the snow . And that's how long
11:37	this little girl might be playing outside in the snow
11:43	. Oh , fun playing out in the water .
11:47	That's awesome . This is so much fun . This
11:50	little boy is probably going to want to play in
11:52	the water for about an hour . Right ? One
11:55	minute wouldn't belong to play in the water at all
11:58	. Remember , one minute is only 60 seconds and
12:02	one second Remember high . That's the second . So
12:05	when hours . A good , long time to play
12:07	out in the water to have a lot of fun
12:09	and to get some really great exercise . Here's our
12:15	final example of an hour . This little girl is
12:18	taking a nap . A nap oftentimes takes an hour
12:23	. One minute wouldn't be long enough for a really
12:26	good nap . and one second . Well , you
12:29	already know how long the second is . A second
12:31	wouldn't do it all either and hours a good long
12:34	time on the clock hours are shown with the thick
12:42	short line and that's the line on the clock that
12:46	moves the slowest . Because ours are so long now
12:53	as you remember before , every unit of time has
12:57	an abbreviation , and an abbreviation is a short form
13:02	of a word . Okay , these kids already know
13:06	this , okay ? And why is this penguin moving
13:08	? So the abbreviations of an hour our hr or
13:15	just h Here's an example . One hour could be
13:19	written one hr or one h now , five hours
13:27	could be abbreviated five hr or five age and 24
13:34	hours , which is how long a day is Could
13:37	be abbreviated 24 hr or 24 age . Well ,
13:43	there you have it . Those are the three main
13:46	units of time in the day , seconds , minutes
13:50	and hours . And now you understand them all .
13:52	And I think it's time for this to be done
13:55	. But we appreciate you being with us , and
13:58	we hope you'll join us again soon because we have
