00:00I wanna know why things happen and how, and I wanna know everything now, oh yeah!
00:06How does this thing work? Why does that stuff change?
00:09How does that do what it just did?
00:11Hmm, what's up with the sky? Do you think I could fly?
00:14The world is spinning and I wanna know why!
00:16I got a lot of questions and big ideas!
00:19I'm Sid, the Science Kid!
00:22Ladies and gentlemen, please give it up for the one and only Sid!
00:30That's me! Thank you, thank you very much!
00:33Yeah! Hey Arnie, give me five, buddy!
00:37Okay, maybe later.
00:39Hey, welcome to my room!
00:44Oh no! Arnie, look!
00:47Oh, the frozen ice pop that my mom made me melted!
00:51I was gonna eat this, but I forgot about it.
00:55I guess the ice pop melted overnight.
00:58Doesn't it bother you when that happens?
01:01It bothers me.
01:03Now, I know ice pops melt, but why can't my ice pops just stay frozen?
01:10Why can't all things just stay frozen?
01:13I just gotta know.
01:15Why do my ice pops have to melt, melt, melt, melt, melt?
01:21Sid, breakfast time!
01:23Oh boy!
01:26Breakfast time!
01:29Mom, Dad!
01:32Look, I left my ice pop on my table overnight and it melted.
01:37You left an ice pop on your table?
01:39Uh-oh!
01:40Yes, which I shall clean up after breakfast.
01:44Thank you, Sid.
01:46You know, it's too bad it melted, but you could always make more.
01:50Really? We can make more ice pops?
01:53Sure you can.
01:55Um, how do ice pops freeze?
01:58That's a great question, Sid.
02:00I'll tell you what, I'll do some research on the computer so I can show you.
02:03Mom's really good at computer stuff.
02:06All righty, here we go.
02:08I'll read the directions and you and Dad can make some more ice pops.
02:11Oh, okay! I am on it!
02:14Yes, we are going to make ice pops!
02:17Yeah!
02:18I think there's some juice in the fridge.
02:20Come on, let's take a look.
02:21Oh boy!
02:22Okay, ready?
02:24Step one.
02:25First, you put a slice of banana at the bottom of a cup.
02:28Then, you poke an ice pop stick into the banana.
02:32That way the stick won't fall over.
02:34Next, pour in your juice.
02:37Then, put the cup in the freezer.
02:39Then, the really cold freezer freezes it up.
02:42Ah, before you know it, you have a yummy ice pop!
02:48Okay, two cups ready to go in the freezer.
02:51One for Sid, and one for his friend Gabriela.
02:55One for Gabriela?
02:57Yeah, you and Gabriela have a play date after school, remember?
03:00Oh yeah!
03:03Gabriela is my best friend in the whole wide world!
03:08Hey, let's put those cups in the freezer, it's ice pop time!
03:11It's ice pop time!
03:16Okay, all you have to do is wait for them to freeze, and you've got yummy ice pops!
03:24Hey, they're not ready.
03:26They need more time than that, Sid.
03:29Are they frozen now?
03:31Not yet.
03:33How about now?
03:35Sid, it's gonna take some time. You just have to wait, buddy.
03:40Okay.
03:41And you have to eat breakfast, because we have to hot-tail it to school soon.
03:45Oh yeah.
03:47I love my mom. My mom is cool.
03:50But now it's time for having fun in school!
03:53Yeah!
04:02I'm looking for my friends!
04:04I'm looking for you!
04:06There's Gabriela!
04:08Watch what I can do!
04:10La-la-woo!
04:12La-la-woo!
04:14Oh yeah!
04:15Wow!
04:16I'm looking for my friends!
04:18I'm looking for you!
04:20Hey, there's Cheryl!
04:21Yeah, check out my moves!
04:27I'm a rock star!
04:30I'm a rock star!
04:32Cool!
04:33I'm looking for my friends!
04:35I'm looking for you!
04:37Hey, there's Meg!
04:38May I show you how I groove?
04:45Hey!
04:46Ruby!
04:47We're looking for our friends!
04:49We're looking for you!
04:51Hey, there's Sid!
04:52Did you hear the one about the kid who wanted to know everything about everything?
04:56That's you!
04:58That's you!
04:59La-la-woo!
05:00La-la-woo!
05:01La-la-woo!
05:02Oh yeah!
05:04We're looking for our friends!
05:06And look what we found!
05:08We found each other!
05:10Friends!
05:11La-la-woo!
05:12And now it's time for the Sid Survey!
05:15Hello, I am Sid, roving reporter, with today's survey.
05:19The question?
05:20Have you ever eaten something frozen that melted?
05:25Hey, you can think about things that melt too.
05:29Oh, May!
05:30I have a survey question.
05:32Have you ever eaten something frozen that melted?
05:35Well, one time during the summer, I had an ice cream sandwich melt all the way down to my elbow.
05:41And my elbow was not very happy about it.
05:44Isn't that right, elbow?
05:45Yeah.
05:46Well, thank you, May.
05:48And elbow.
05:49You're welcome.
05:50Oh, Gabriella!
05:52Gabriella, have you ever eaten something frozen that melted?
05:56Actually...
05:58Yes!
05:59Once, I was eating a red, white and blue frozen ice pop.
06:02And it melted on my hand.
06:04And then, I had a red, white and blue hand.
06:07Whoa!
06:08Colorful!
06:09Thanks!
06:13Once, I was eating a big bowl of cherry banana chocolate chip ice cream.
06:19And it melted.
06:23Oh.
06:24And...
06:25So, it changed into cherry banana chocolate chip soup!
06:30That sounds yummy!
06:33It was so good!
06:37And now, the results of my survey.
06:40Gabriella's ice pop melted.
06:43May's ice cream sandwich melted all the way to her elbow.
06:47And Gerald says his big bowl of ice cream melted and changed into ice cream soup.
06:55And I hope you thought about something that melts too.
06:59So, there you have it.
07:01I am Sid, roving reporter and melting expert.
07:05Everybody, rug time!
07:07That's Teacher Suzie!
07:09It's rug time, come on in!
07:11Rug time, take a seat!
07:13Rug time, we're ready!
07:15Everybody, move your feet!
07:17Rug time, Teacher Suzie!
07:19Good times, on the way!
07:21Rug time, come on in!
07:23We've got a lot to learn today!
07:263, 2, 1, blast off!
07:31We're over here, Astronaut Gerald!
07:33Roger that, Teacher Suzie!
07:35Coming in for a landing!
07:37Oh, man!
07:38Make room!
07:41Oh, boy!
07:46So, how's everyone doing today?
07:48Oh, we were talking about frozen stuff that melted.
07:51Oh, yeah, because Sid left out his ice pop and it melted.
07:55Yeah.
07:56Yep, sad but true.
07:58Oh, sorry about your ice pop, Sid.
08:00But I bet all of you have had something frozen that melted, right?
08:04Yeah, I have.
08:05So, here's a question for everyone.
08:07If you wanted something to stay frozen, where's the best place to keep it?
08:13Oh, uh, somewhere c-c-c-cold!
08:18I think Gerald has the right idea.
08:20Where is somewhere really c-c-c-cold?
08:25Oh, in the freezer!
08:28Right!
08:31Oh, no, Sid!
08:32Your ice pops melted because they weren't in the freezer.
08:36Poor little ice pops.
08:38May's right.
08:39You know, when juice or something liquid like water is kept really cold,
08:44over time it freezes and changes to ice.
08:47Yeah, and then when it's not in a cold place, it melts, right?
08:52You got it.
08:53Hey, then can you freeze the water back into ice?
08:56Great question, Sid.
08:58Yes, you can.
08:59When something can change back and forth like that, it's called reversible change.
09:05Wow!
09:06So, water can freeze and become ice and then melt and then freeze back into ice.
09:14And that's reversible change.
09:16Yeah!
09:17I like that change.
09:18Me too.
09:20So, who wants to see what happens when something frozen starts to melt?
09:25We do!
09:27Well, I know the perfect place to investigate freezing and melting.
09:30Okay, scientists, you know where we're going.
09:33To the Super Fab Lab!
09:36Grab your journals and let's go!
09:38All right!
09:39Super Fab Lab!
09:48Super Fab Lab!
09:50Investigate!
09:52Explore!
09:53Discover!
09:55We're going to do an investigation called the Ice Block Investigation.
10:03And guess what?
10:05The fruit frozen inside the ice is going to be your snack today.
10:11How are we going to eat the fruit if we can't get to it?
10:14Well, what happened to Sid's ice pop?
10:17It melted!
10:20Aha! We'll wait for the block of ice to melt into water.
10:25Hold on.
10:27It takes a long time for ice to melt.
10:29Oh, no.
10:31Don't worry, frozen fruit. We'll get you out of there.
10:34Yeah, and then we'll eat you!
10:37I have an idea. Let's make the ice melt faster.
10:41Maybe we can put a block of ice in a microwave.
10:44That'll melt it really fast.
10:46Well, I'm afraid the block of ice is too big for a microwave.
10:50But I like the way you're thinking, May.
10:52Thank you.
10:53Oh, we can blow hot air on it!
10:57Maybe not.
10:59Hey, what if we pour something warm on the big block of ice to make it melt?
11:03Good idea, Sid.
11:05Look around. Is there some sort of liquid we could use here in the Super Fab Lab?
11:14Warm water from the sink!
11:16Good thinking, Gabriela.
11:18I'll go get some warm water and we'll start our investigation.
11:21Yeah!
11:24Here is our ice block filled with fruit.
11:27Go ahead and touch it.
11:29How does it feel?
11:31Is the ice cold?
11:33Is it hard?
11:35Is it wet?
11:37Draw a picture of what the ice block looks like in your journal.
11:42Okay, here's your challenge.
11:45Try to get the fruit out of the ice.
11:47Go for it!
11:49Hmm, it isn't easy to break through the ice.
11:51It's frozen solid.
11:53Now an adult is going to pour warm water over the block of ice.
11:59Wow! What is the warm water doing to the ice?
12:02It's changing the ice. It's starting to melt.
12:05Go ahead and touch the ice block again.
12:07How does it feel now?
12:09I think we need to pour some more warm water over the ice.
12:12Look at that!
12:14It's starting to melt!
12:16Now pour some more warm water over the ice.
12:19Look! It's melting even more!
12:21Alright! The ice changed! It melted!
12:25Now you can reach the fruit.
12:31Go ahead. Enjoy your fruit snack.
12:34And when you're done eating, draw your observations in your journals.
12:38Remember what the ice was like when it was frozen.
12:41And then after we poured on the warm water and it melted.
12:47Mmm! These grapes are good and cold!
12:51Mmm! I'm glad you're all enjoying your chili fruit snacks.
12:54Oh, I can't wait to see what observations you made in your journals.
12:57Um, Sid, let's take a look at your journal first.
13:00Oh, okay.
13:02Um, here's the big block of ice before you poured on the warm water.
13:06And here's the ice after you poured the warm water.
13:09When the ice melted, it made a big puddle of water at the bottom.
13:12When the ice melted, it made a big puddle of water at the bottom.
13:15And all the fruit went for a swim.
13:18Oui!
13:19Good observation, Sid!
13:21Okay, Gabriela, let's see your journal.
13:24Oh, sure!
13:25You poured warm water on the ice, but it only melted a little bit.
13:29I poked at the ice and I still couldn't get to the fruit.
13:33Then you poured on more warm water and even more warm water.
13:37It took so long for the ice to melt so we could eat the fruit.
13:41Great observations, Gabriela.
13:43All of you scientists made great observations.
13:46So now I have a question.
13:48If we put the melted water into the freezer,
13:51do you think we could change it back into ice?
13:54Hmm...
13:56Yes, because ice can melt into water.
14:00Yeah, and then freeze back into ice.
14:02Yeah, and that's reversible change.
14:05Yes, I'm impressed!
14:07My scientists know so much about freezing, melting and reversible change.
14:12I think it's time to play with all your new ideas.
14:16Hooray!
14:18Go ahead.
14:19All right.
14:21It's time for...
14:23Good Laughter Noon!
14:29Why was the baby juice pop crying?
14:31I don't know! Why?
14:33Because he wanted his ice mom an ice pop!
14:38Knock, knock!
14:40Who's there?
14:41It's me, May!
14:43Sid, you're a really nice friend.
14:45Oh, um... Well, thanks, May.
14:47Uh, do you have a joke?
14:49Nope. Bye-bye!
14:53Hey, hey, Gabriela!
14:55Yes?
14:56What do you get when you mix water, frozen juice and slushy ice?
15:01Water, juice and slushy ice... Hmm...
15:05I don't know. What?
15:06You get a frozen, juicing, slushing, popper, schmopper, blabber, quabber, splabblabblabla...
15:16Now that's funny!
15:26Okay, let's play freeze.
15:29When I yell freeze, your whole body becomes frozen and you can't move.
15:35And when I say sun's out, that means it's warm and so you melt and dance around!
15:43I like this game!
15:45Ready? Freeze!
15:48I'm f-f-f-freezing!
15:52And now, the sun's out!
15:54Melt!
15:57I'm melting!
15:58We're changing!
16:00Now, freeze!
16:04Sun's out!
16:05Melt!
16:08Now, freeze!
16:11Sun's out!
16:12Melt!
16:13Freeze!
16:14Melt!
16:15Freeze!
16:16Melt!
16:17Freeze!
16:18Freeze!
16:19Melt!
16:20It's too fast!
16:22I'm just gonna melt!
16:28And now...
16:29It's time...
16:30For Suzy...
16:31To sing!
16:33Go Suzy!
16:38Why, thank you!
16:39Thank you and thank you!
16:43You know, all this talk about reversible change reminds me of a couple penguin friends of mine.
16:53In the summertime we dip and dive
16:55In the clear blue water that shimmers
16:59The sun shines down and we splash around
17:02You won't see happier swimmers
17:05Then winter brings the cold and so the water starts to freeze
17:08We don't mind when it turns to ice
17:11Can we slide on our belly sleeves?
17:15On Penguin Pond, things keep changing
17:18From ice to water and water to ice, back and forth
17:21We live in a changing paradise
17:23What was water now is ice
17:25Till the summer sun melts the ice and then
17:28We'll be swimming once again
17:30On Penguin Pond
17:34We swim and slide on the same pond
17:36We don't find it strange
17:38Water turns to ice and back to water
17:41That's called reversible change
17:44On Penguin Pond, things keep changing
17:47From ice to water and water to ice, back and forth
17:50We live in a changing paradise
17:52What was water now is ice
17:54Till the summer sun melts the ice and then
17:57We'll be swimming once again
17:59On Penguin Pond
18:27Just frozen water, right?
18:29You're right!
18:30And the icy pond melts to water
18:33And then freezes back into an icy pond
18:36That's called reversible change
18:40Oh, I'm so impressed with all my scientists
18:43You're all reversible change experts
18:46OK, let's get ready to go home
18:48And you can tell everyone about freezing and melting
18:51All right!
18:52Come on, Gabriella, you've got a play date at my house today
18:55Yeah, a play date!
18:57All right, it's time to go home
19:02Backseat driving with Grandma
19:08So, a play date today, you guys are lucky
19:11Yeah, we're really lucky
19:13My ice pops in the freezer, we'll be ready
19:15Hey, Sid's grandma, did they have freezers when you were a little girl?
19:19Oh, of course we had freezers
19:21But when my grandma was a little girl
19:23That's a different story
19:26When my grandma was growing up, she didn't have a freezer
19:29She had an ice box
19:30And do you know what was inside?
19:32Ice!
19:35It was a big old box with an ice block
19:37And everything next to the ice stayed cold
19:39And when it was hot outside, the ice inside the box would melt
19:43Sometimes you'd open up the door
19:45And all you'd find was a big old puddle of water
19:48Water! Yeah, how do you like that?
19:50And then, to keep things cold, you had to put in a brand new block of ice
19:55Hey, that's what happened to my ice pops
19:57They melted
19:59Uh, Grandma, do you think my new ice pops are frozen yet?
20:02I don't know, let's go find out!
20:04Yay!
20:07My grandma's the coolest grandma in the whole world
20:12We learned something cool, something cool today
20:15We know it upside down and inside out
20:17We learned all about
20:20Reversible change
20:26Two scientists in the house
20:30Back!
20:37Do you think they're frozen yet?
20:39I'm not sure, do you think they're frozen?
20:41I don't know!
20:42I don't know either
20:43Well, there's only one way to find out if they're frozen
20:46Here we go
20:47Juice!
20:48Please, please, please, please be frozen
20:50Oh, pretty, pretty, pretty, please be frozen
20:52Uh-oh, guess what?
20:54You have frozen juice pops!
20:56Yay!
20:58Ice pops!
20:59Oh, and they look really good
21:02So, I say, eat up, kids!
21:05Yum!
21:06Thank you!
21:07Thanks!
21:08You're welcome
21:09Yum, yum, yum!
21:39What if I wanted to make a really big juice pop
21:42that wouldn't fit in the freezer?
21:44How would I do that?
21:48I've got it!
21:49Okay, here's my super-duper-ooper-schmooper big idea!
21:55I'm going to invent the biggest juice pop in the whole world
21:58So first, I'll need a super-huge tank of orange juice
22:02Then, I'll take a helicopter and fly the tank to the South Pole
22:06where it's really, really cold
22:09The whole place is like a giant outdoor freezer
22:12Then the big tank of juice will freeze into a giant juice pop
22:17But here is the best part
22:19I'm going to carve my giant juice pop into a special shape
22:23When I'm all done, I'll have the world's biggest ice pop
22:27in the shape of my favorite stuffed animal dinosaur, Arnie!
22:32And that's my super-duper-ooper-schmooper big idea!
22:37Thank you!
22:39Oh, hey, watch this!
22:46Yoo-hoo!
22:50It's cold, I'm ice
22:52Now it's hot, I'm water
22:55I am Sid
22:58I am Sid, the Science Kid
