00:00Good morning, good afternoon, good night!
00:08Good morning, good afternoon, good night!
00:16Good morning, good afternoon, good night!
00:18Did you notice the pattern?
00:20Well, I'm Dr. Jeff, and today on 3 to Wonder,
00:24we'll explore patterns in the sky!
00:26Here we go!
00:30Today, we'll learn that the sun rises in one part of the sky
00:35and sets in another part.
00:38That the moon and stars also rise in one part of the sky
00:43and set in another part.
00:46These movements are patterns because they repeat each day.
00:55Good morning, Dr. Jeff.
00:56Good morning, Dr. Jeff!
01:00Hi, Addison. Hi, EJ.
01:03How's it going? It's the morning already?
01:06The sun is already up, just like it is every morning.
01:09And you did say to meet you here bright and early,
01:13so we're here and we're ready to learn about the patterns in the sky.
01:16Well, great! It's time to head into our imaginations!
01:21Follow me!
01:27Here we go!
01:31In 3, 2, 1, there!
01:34Our imaginations are amazing!
01:41I bet we can observe all kinds of cool patterns here.
01:44Yep, any pattern we can imagine.
01:47But first, let's talk about what a pattern is.
01:51A pattern is when something repeats the same way over and over again.
01:57Because it repeats the same way, you can predict what happens next.
02:01That's right! It lets you predict the future!
02:05Watch this!
02:09Whoa! A blue triangle!
02:12And a yellow one!
02:14And another blue one!
02:16And a yellow one again!
02:20It's a pattern!
02:22Patterns repeat in the same order again and again.
02:27And when we see patterns, we can predict what will come next.
02:32Let me try!
02:33I predict that the next triangle will be a blue one.
02:39Cool! I predict the next shape will be a yellow one.
02:44Excellent!
02:45Once we know what the pattern is, we can tell what will come next.
02:50That's right!
02:51Now, Addison, what was it you said back at the lab about the sun?
02:56I said the sun is up just like it is every morning.
03:00That sounds like a pattern!
03:02Let's learn more about them using more of our imagination!
03:11Let's observe this pattern!
03:13Every day the sun rises in one spot and starts moving across the sky from east to west.
03:21The sun is highest in the middle of the day.
03:25That's lunchtime for me!
03:26Yum!
03:27The sun gets lower in the afternoon.
03:31Then it sets in the west at night. That's when we go to sleep!
03:36Hmm! I think you're right, EJ!
03:39And the next day, the sun comes back up again in the morning!
03:49The sun moves across the sky in a pattern.
03:51Yesterday, the sun moved from east to west.
03:54And today, it came up again, just like before.
03:57So, can we predict that it will follow the same path as yesterday?
04:01We can!
04:03Because it's a pattern, we can make predictions from what we observe.
04:06I predict that the sun will set.
04:13I predict that it will rise again in the morning.
04:16It's like knowing the future!
04:22Here in our imaginations, the pattern of the sun moving across the sky happens fast.
04:30But in real life, it takes a full day.
04:33Observing patterns helps us know what's going to happen next.
04:37Are there other patterns we can see in the sky at night?
04:40Well, sure! After the sun goes down, it gets dark.
04:46And we can see that, just like the sun, the moon moves across the sky in a pattern!
04:52The moon comes up in one place and moves across the sky.
04:58And then it sets in another place.
05:00It does it again every night!
05:03So, just like with the sun, we can predict how it will move each time.
05:08So, if it rises in the east and sets in the west, then the next day it will follow the same pattern.
05:18That's right! The sun and the moon both follow the same pattern!
05:24It looks like the stars do too, but only at night!
05:28Well, stars are always out there!
05:30There's enough stars to fill the whole sky!
05:34They're always up there!
05:36So, why can't we see them in the daytime?
05:39We can't see most stars in the daytime because the sun is just too bright!
05:45It lights up everything around us and makes it hard to see the stars!
05:50But different stars are still out there, even during the day?
05:54Yep! We can see a whole bunch of stars with our eyes at night!
05:59And the telescope can magnify things that are far away so we can see them!
06:05Let's see how stars look through our telescope!
06:11Whoa! There are so many!
06:13And in our imaginations, our telescope can magnify things even more than a real one!
06:20And what do you think we would see if we watched these stars all night?
06:26They move across the sky in a pattern too!
06:29You got it!
06:30Stars move across the sky really slowly!
06:34You may not have noticed before!
06:36So, the sun, the moon, and the stars are all things we can observe moving across the sky!
06:42They move in the same way every day!
06:45And from these patterns, we can predict how they'll move tomorrow!
06:49We sure can!
06:50Now it's time to do it yourself!
06:58The sun moves across the sky in a pattern from east to west!
07:03So today, we're going to keep track of how it moves!
07:06All you need is some chalk in a nice sunny place to use it!
07:10First, find a good place to stand!
07:14Then, have a friend draw your shadow for you!
07:23Come back a few hours later and then trace your shadow again!
07:28As the sun moves across the sky, your shadow will move too!
07:35This happens because the sun moves across the sky in the same pattern every day!
07:40Try it yourself!
07:42And now you know!
07:43Until next time, I'm Dr. Jeff!
07:46I'm EJ!
07:46I'm Madison!
07:47And remember, always question, always wonder!
