00:00Today we are going to learn about the units of time.
00:05So as we mentioned earlier, today we are going to learn about the units of time.
00:14There are three main units of time in a day, seconds, minutes, and hours.
00:24A second is the smallest unit of time, it's so tiny, a minute is a lot bigger than a second,
00:31and then an hour is even bigger, an hour is the biggest unit of time in a day.
00:40We are going to look at each of these individually, okay?
00:45It is going to be a great time.
00:48Get it?
00:53That's funny, right?
00:57First we are going to learn about seconds.
01:03A second is the smallest unit of time, it's extremely short.
01:08Now a fair warning to you, you are about to see some very cute animals that are going
01:12to help us understand just how long a second is.
01:16Hey, what did we say?
01:19We warned you.
01:20Okay.
01:21The time that it takes this cute little dog to jump is a second.
01:28It's just like a moment.
01:30Boom.
01:31The dog jumps in the air for a second.
01:33Down.
01:34And you see how this dog is jumping over that pole.
01:37Really cool.
01:38Great dog.
01:39It takes just a second to jump.
01:42That's a second.
01:44That's the sound.
01:45Whoosh.
01:46That's a second.
01:48Okay, another cute animal.
01:50This is a cat.
01:51And this cat is blinking.
01:53The time it takes to blink is a second.
01:57Not just for cats.
01:58For humans.
01:59Why don't you give it a try?
02:00Go ahead and blink.
02:02Yeah.
02:03That's a second.
02:04Can you blink again?
02:06That's another second.
02:07That's another second.
02:08Can you blink again?
02:10That's a second.
02:11It's so short.
02:12It's such a short amount of time.
02:15Could you blink again?
02:16Okay.
02:17That will be the last time.
02:18Okay.
02:19It's a second.
02:20It's a second to blink.
02:22Oh, who doesn't love a good seal?
02:27Here's a seal in the water saying hi by waving.
02:32That wave takes just a second.
02:35Did you know when we say hi, that takes a second too?
02:39Why don't we give that a try?
02:41Say the word hi.
02:42Hi.
02:43Hi.
02:44Hi.
02:45That's a second.
02:47Hi.
02:48That's a second.
02:50Hi.
02:51Now, I don't want you to annoy people around you, but I want you to understand it just takes
02:55a second to say hi or to wave.
03:00It usually takes just a second.
03:06On a clock, seconds are shown with the thinnest line.
03:10It's also the line that moves the fastest because seconds are the shortest period of time.
03:16Now, you might not realize this, but every unit of time has an abbreviation.
03:26An abbreviation is a short form of a word, and seconds actually have two abbreviations.
03:37The abbreviations of seconds are sec or just the letter S. Here's an example.
03:46You could say one second, or if you wanted to write it with an abbreviation, you could
03:51write one sec or just one S. Here's another example.
04:01Five seconds could be written five sec or five S. Now, you don't always have to do that.
04:08You don't always have to use an abbreviation, but if you want to abbreviate and make seconds
04:12shorter, you can just write five sec or five S. The final example, ten seconds can be written
04:23ten sec or ten S. Sec or S are abbreviations of the word seconds.
04:35Minutes are the shortest unit of time.
04:42Next, we're going to talk about minutes.
04:46A minute is the next biggest unit of time after seconds.
04:51Now, how much bigger is a minute than a second?
04:56Well, believe it or not, a minute is 60 seconds.
05:0260 seconds.
05:0360 is a lot.
05:04Now, you might be wondering, how much is 60?
05:06I'd love to see that.
05:08Well, look at this.
05:10Ho, ho, ho, ho.
05:11It's a lot.
05:12It's a lot.
05:13It's a lot.
05:1460 is a lot.
05:15A minute is 60 seconds.
05:17Here's an example of something that takes about a minute.
05:24A little girl blowing bubbles takes about a minute.
05:27About 60 seconds.
05:29For a while, she'll blow these bubbles and then she'll be done.
05:32She might spend a couple minutes or she might just spend a minute.
05:36A minute.
05:37It's not too long, but it's not too short.
05:39It's a minute.
05:43This little boy's tired.
05:44Maybe he played for a long time and he just wants to sit down for a minute.
05:48This is something that might take a minute, sitting down and just taking a break.
05:53It wouldn't be enough of a break to just take a second break, but a minute can help
06:00him rest.
06:01A minute is 60 seconds.
06:03It's enough time to take a break, to breathe for a while, and then to go back to playing.
06:10Here's our final example of a minute.
06:12A little girl who's cuddling with her teddy bear.
06:16Maybe she named him Mr. Perkins and maybe she'll give him hugs every once in a while,
06:21but now she's taking her time to cuddle him for 60 seconds.
06:26A minute.
06:27Maybe she'll spend about a minute.
06:29A second would just be too short to hug Mr. Perkins, but cuddling for a minute.
06:35She would take a minute to do that.
06:40On a clock, minutes are shown with the longest line.
06:44So when you look at a clock, the longest line called a hand on a clock.
06:48That longest hand measures the minutes.
06:55Now remember, every unit of time has an abbreviation.
06:59And remember, an abbreviation is just a short form of a word.
07:04The abbreviation of minutes is min, m-i-n, min.
07:14Here's an example.
07:15One minute would be abbreviated one min.
07:19Look at this one.
07:20Five minutes would be abbreviated five min.
07:32Ten minutes would be abbreviated ten min.
07:36A minute is the next biggest unit of time after seconds.
07:46The last unit of time we're looking at today are hours.
07:49Hours are the largest units of time in the day.
07:54In fact, in a day, there's only 24 of them.
07:58Not many at all.
08:02Okay, so how long is an hour exactly?
08:05Well, an hour is 60 minutes.
08:08Do you remember how big the number 60 is, right?
08:11Ooh!
08:13Ah!
08:15Lots of minutes.
08:1660 minutes.
08:17An hour is 60 minutes.
08:19Remember, a minute is 60 seconds.
08:21So, it's a lot of time.
08:25Here's an example of an hour.
08:26This girl playing out in the snow.
08:29This girl would want to play out in the snow for like an hour, right?
08:3360 minutes.
08:34One minute wouldn't be enough playing out in the snow.
08:37And one second, well, one second is like, hi!
08:40And that's a second, remember?
08:42So, an hour is 60 minutes.
08:44It's a good long time to play out in the snow.
08:47And that's how long this little girl might be playing outside in the snow.
08:55Ah!
08:56Fun!
08:57Playing out in the water!
08:58That's awesome!
08:59This is so much fun!
09:01This little boy is probably going to want to play in the water for about an hour, right?
09:06One minute wouldn't be long to play in the water at all.
09:09Remember, one minute is only 60 seconds.
09:12And one second, remember?
09:14Hi!
09:15That's a second.
09:16So, an hour is a good long time to play out in the water, to have a lot of fun, and
09:21to get some really great exercise.
09:23Here's our final example of an hour.
09:28This little girl is taking a nap.
09:31A nap oftentimes takes an hour.
09:34One minute wouldn't be long enough for a really good nap.
09:38And one second, well, you already know how long a second is.
09:41A second wouldn't do it all either.
09:43An hour is a good long time.
09:47Hours are shown with the thick, short line.
09:53And that's the line on the clock that moves the slowest because hours are so long.
10:03Now, as you remember before, every unit of time has an abbreviation.
10:08An hour is an abbreviation.
10:09And an abbreviation is a short form of a word.
10:14Okay?
10:15These kids already know this.
10:17Okay?
10:18And why is this penguin moving so fast?
10:21The abbreviations of an hour are HR or just H.
10:27Here's an example.
10:28One hour could be written 1 HR or 1 H.
10:36Now, five hours could be abbreviated 5 HR or 5 H.
10:44And 24 hours, which is how long a day is, could be abbreviated 24 HR or 24 H.
10:53Well, there you have it.
10:55Those are the three main units of time in a day.
10:59Seconds, minutes, and hours.
11:01And now you understand them all.
11:03And I think it's time for this to be done.
11:06But we appreciate you being with us.
11:09And we hope you'll join us again soon because we have so many fun things to learn.
11:13We'll see you soon.
11:14Bye.
11:15Bye.
11:16Bye.
11:17Bye.
