0:00:53 > 0:00:55# Oh, yeah! #
0:00:57 > 0:01:01Oh, hello there. This is one of my favourite things.
0:01:01 > 0:01:05It's a model of our solar system and here's our planet, Earth.
0:01:05 > 0:01:10And all the planets spin around a huge sun in the middle.
0:01:10 > 0:01:16- ALARM BEEPS - Oh, I hear a beep, I see a flash. I wonder what they're going to ask?
0:01:20 > 0:01:22BOTH: Hi, Nina!
0:01:22 > 0:01:27- Hi!- We've got a question for you. - What planets are near us in space?
0:01:27 > 0:01:31That's a great question. What planets are near us in space?
0:01:31 > 0:01:34We can have lots of fun exploring this question.
0:01:34 > 0:01:37Why don't you come down to my workshop
0:01:37 > 0:01:41- and we'll investigate? - BOTH: See you soon, Nina, bye!
0:01:41 > 0:01:45Bye! Well, I'm going to need some help to answer this one
0:01:45 > 0:01:46and I know just who to ask.
0:01:46 > 0:01:49OK, Neurons, time to get to work.
0:02:03 > 0:02:05NEURONS: Neurons at the ready, Nina.
0:02:06 > 0:02:10OK, today's question is, what planets are near us in space?
0:02:10 > 0:02:13Which Neuron do you think will be most useful
0:02:13 > 0:02:17- in helping us find the answer? - ALL: Me! Me! Me! Oh, me!
0:02:17 > 0:02:20Will it be fabulous Felix?
0:02:20 > 0:02:23I can help so very much if you need the sense of touch.
0:02:23 > 0:02:25Will it be beautiful Belle?
0:02:25 > 0:02:27I send messages to brain from ear.
0:02:27 > 0:02:30If there's a sound, I'll help you hear.
0:02:30 > 0:02:32Will it be lovely Luke?
0:02:32 > 0:02:34For looking and seeing, day or night,
0:02:34 > 0:02:37I'll help you with your sense of sight.
0:02:37 > 0:02:38Will it be awesome Ollie?
0:02:38 > 0:02:41If it's pongy or whiffy but you can't tell,
0:02:41 > 0:02:45- my messages help your sense of smell. - Or will it be baby Bud?
0:02:45 > 0:02:50Sour, salty, bitter or sweet, I'm your taste buddy whenever you eat!
0:02:55 > 0:02:57It's Luke!
0:02:57 > 0:03:02NEURONS: Go, Luke! Go, Luke! Go, Luke!
0:03:04 > 0:03:08Cool, Nina. I'll be looking out to help you.
0:03:08 > 0:03:11Today's question is what planets are near us in space?
0:03:11 > 0:03:14Because planets are something we look at,
0:03:14 > 0:03:16our sight Neuron, Luke, will be helping us.
0:03:16 > 0:03:18But stand by, Neurons, I think
0:03:18 > 0:03:20I'll need help from all of you.
0:03:20 > 0:03:25Right, I need to get the workshop ready before the explorers arrive.
0:03:25 > 0:03:29Dylan loves street-dancing and Ewan loves finding crabs at the beach,
0:03:29 > 0:03:34but they both want to know what planets are near us in space?
0:03:34 > 0:03:38I want to find out about how big planets are.
0:03:38 > 0:03:40What planets are closest to Earth.
0:03:40 > 0:03:45So today, for one day only, Dylan and Ewan become the explorers!
0:03:49 > 0:03:50- Hi, guys.- BOTH: Hi, Nina
0:03:50 > 0:03:54Welcome to my workshop and thank you for your great question -
0:03:54 > 0:03:56what planets are near us in space?
0:03:56 > 0:04:00To find out the answer, let's start by using our senses.
0:04:00 > 0:04:04NEURONS: Woo! Woo! A senses experiment. We're ready, Nina!
0:04:04 > 0:04:07First, we need to explore what planets are,
0:04:07 > 0:04:09so let's have a closer look.
0:04:09 > 0:04:13- Can you tell me the name of the planet we live on?- BOTH: Earth.
0:04:13 > 0:04:16That's right, we live on the beautiful planet Earth.
0:04:16 > 0:04:18It's very special,
0:04:18 > 0:04:21it's the only planet we know about where things can live.
0:04:21 > 0:04:25Because they can breath air and there's enough food and water,
0:04:25 > 0:04:28it's not too hot and it's not too cold.
0:04:28 > 0:04:32- How would you describe Earth? - It looks like a big ball.
0:04:32 > 0:04:34Yes, and there are lots of planets near us
0:04:34 > 0:04:36and they're all shaped like a ball.
0:04:36 > 0:04:39But they're different sizes and colours.
0:04:39 > 0:04:41This planet is red, it's called Mars.
0:04:41 > 0:04:46And this planet over here, it's blue and it's called Neptune.
0:04:46 > 0:04:50And this one, it's all swirly with a big red spot
0:04:50 > 0:04:53- and it's called Jupiter. - How big are the planets, Nina?
0:04:53 > 0:04:58That's a great question, our next experiment will help to explain.
0:04:58 > 0:05:01We're going to pretend that these balls are planets
0:05:01 > 0:05:04and they're all planets that are near to us.
0:05:04 > 0:05:09Mercury, Venus and there we are on planet Earth, Mars, Jupiter,
0:05:09 > 0:05:12Saturn, Uranus and Neptune.
0:05:12 > 0:05:14Now, which one is the biggest?
0:05:14 > 0:05:17- The stripy one.- Yes, you're right!
0:05:17 > 0:05:20If the Earth was this size then the biggest
0:05:20 > 0:05:23planet near by would be the size of this big ball.
0:05:23 > 0:05:26It's ginormous and it's called Jupiter.
0:05:26 > 0:05:29- Which one of these is the smallest? - That one.
0:05:29 > 0:05:35Yes, if the Earth was this size then the smallest planet near by would be
0:05:35 > 0:05:41the size of this tiny bead and this small planet is called Mercury.
0:05:41 > 0:05:44All of these planets move in a circle around the Sun
0:05:44 > 0:05:47and scientists call this our solar system.
0:05:47 > 0:05:51- How big is the Sun, Nina? - Oh, that's a great question.
0:05:51 > 0:05:54the Sun is bigger than all of the planets.
0:05:54 > 0:05:59If these were the planets, the Sun would look something more like this.
0:06:01 > 0:06:04Look at this! Ha-ha-ha!
0:06:04 > 0:06:07The Sun is massive!
0:06:07 > 0:06:10NEURONS CHUCKLE
0:06:10 > 0:06:13How far away are the other planets, Nina?
0:06:13 > 0:06:14That's a great question
0:06:14 > 0:06:18and we need to go somewhere with a lot more space to find out.
0:06:22 > 0:06:24Off we go for another adventure.
0:06:24 > 0:06:27Nina said it's somewhere with lots of space.
0:06:27 > 0:06:32Maybe we're zooming up to the sky in space jet?
0:06:32 > 0:06:34Oh, no, that would make me all messy.
0:06:34 > 0:06:38We've arrived, but I don't see a spaceship.
0:06:38 > 0:06:42Now your question was, what planets are near us in space?
0:06:42 > 0:06:45Now we're going to explore how far away the planets are.
0:06:45 > 0:06:49The real solar system is really, really, really big, so we're
0:06:49 > 0:06:54going to pretend that this gigantic beach is our very own solar system
0:06:54 > 0:06:57and our pretend planets have been spread out
0:06:57 > 0:07:01along the beach and... Oh, look what we have over here.
0:07:01 > 0:07:04Can you remember what this is called?
0:07:04 > 0:07:05BOTH: The Sun.
0:07:05 > 0:07:08Yes, and the Sun is bigger than all the planets,
0:07:08 > 0:07:12so it's our job to find the planets. So let's go planet spotting!
0:07:18 > 0:07:22This is the smallest planet, can you remember its name?
0:07:22 > 0:07:24BOTH: Mercury!
0:07:24 > 0:07:28Yes, Mercury is the smallest planet and it's closest to the Sun.
0:07:28 > 0:07:30Let's see what's next.
0:07:30 > 0:07:31- Yeah!- Yeah!
0:07:33 > 0:07:37This is Venus, it's second closest to the Sun
0:07:37 > 0:07:40and a similar size to our planet Earth.
0:07:45 > 0:07:49Oh, now this looks familiar. Who know what this planet's called?
0:07:49 > 0:07:55- Me, me! I know, I know!- Yes, Bud? - That's our planet, Earth.
0:07:55 > 0:07:56Well done, Bud.
0:07:56 > 0:07:59This is planet Earth where we live and it's the
0:07:59 > 0:08:01third planet from the Sun.
0:08:07 > 0:08:10This is Mars and scientists call it the red planet.
0:08:10 > 0:08:12It's smaller than Earth
0:08:12 > 0:08:16and because it's further away from the Sun, it's also colder.
0:08:16 > 0:08:19Now, the next planet is really, really far away.
0:08:19 > 0:08:22I think we need some help to get there.
0:08:22 > 0:08:24Seat belts on, everyone.
0:08:32 > 0:08:35Now, explorers, what do you remember about this?
0:08:35 > 0:08:37It's gigantic Jupiter.
0:08:37 > 0:08:40Yeah, Jupiter is the biggest planet
0:08:40 > 0:08:44and it's much further away from the Sun that the Earth is.
0:08:54 > 0:08:58- This is Saturn and what's Saturn famous for?- It has rings around it.
0:08:58 > 0:09:01Yeah, Saturn is well known for its rings.
0:09:11 > 0:09:14Wow, we've travelled quite a distance to find this planet.
0:09:14 > 0:09:17This is called Uranus and because Uranus is
0:09:17 > 0:09:20so far away from the Sun, it's a very cold planet.
0:09:20 > 0:09:23Explorers, we're doing really well.
0:09:23 > 0:09:25We found the Sun and seven planets,
0:09:25 > 0:09:28which means we've got one more planet to discover.
0:09:28 > 0:09:31- Do you know what it's called? - Neptune.
0:09:31 > 0:09:34That's right and Neptune is the furthest away planet
0:09:34 > 0:09:37from the Sun, so I hope we can find it.
0:09:40 > 0:09:42ALL: Yay!
0:09:42 > 0:09:44NEURONS: Hooray!
0:09:44 > 0:09:45We found Neptune!
0:09:45 > 0:09:50And, as we can see, Neptune is very, very far away from the Sun.
0:09:50 > 0:09:51Wowee!
0:09:51 > 0:09:55The solar system is massive!
0:09:55 > 0:09:58But there's much more to find out about planets.
0:09:58 > 0:10:02It's time for another experiment, let's go, explorers.
0:10:04 > 0:10:08Now, all planets move around the Sun like this.
0:10:09 > 0:10:14And we're going to pretend that our big beach ball is the Sun
0:10:14 > 0:10:18and you guys are going to be planets, using those bouncers.
0:10:18 > 0:10:20So, Dylan, you're going to be the Earth.
0:10:20 > 0:10:22The Earth is quite close to the Sun,
0:10:22 > 0:10:25so you'll be following the blue flags around the Sun.
0:10:25 > 0:10:29Ewan, you're going to be Neptune, the furthest planet
0:10:29 > 0:10:33from the Sun, so you'll follow the yellow flags around the Sun. OK?
0:10:33 > 0:10:35Now go and grab your bouncers.
0:10:39 > 0:10:42Ready, steady, go!
0:10:47 > 0:10:51Bouncing around the solar system, cool, man.
0:11:01 > 0:11:03That's it!
0:11:03 > 0:11:05And stop, Dylan, well done.
0:11:05 > 0:11:09Ewan, you've got further to go than Dylan.
0:11:13 > 0:11:16- And stop! Yeah! - NEURONS: Hooray!
0:11:18 > 0:11:22Well done, that was fantastic! How did it feel being planets?
0:11:22 > 0:11:23It was great.
0:11:23 > 0:11:27Dylan, you were the Earth and, Ewan, you were Neptune.
0:11:27 > 0:11:31- Which planet went round the Sun quicker?- It was me, Earth.
0:11:31 > 0:11:34That's right, let me show you.
0:11:34 > 0:11:37Earth is nearer the Sun, so that journey was quicker.
0:11:37 > 0:11:40Neptune took longer because it's much further away.
0:11:40 > 0:11:42That's right, the time
0:11:42 > 0:11:46it takes the real Earth to go round the Sun is called one year.
0:11:46 > 0:11:49A year is the time we have to wait between birthdays.
0:11:49 > 0:11:52Because Neptune is so far away from the Sun,
0:11:52 > 0:11:55it takes 165 years to make the same journey.
0:11:55 > 0:11:57You'd be waiting a really,
0:11:57 > 0:12:00really long time for a birthday on Neptune, Nina.
0:12:00 > 0:12:03He-he, that's right, Bud.
0:12:03 > 0:12:06# Nina and the Neurons. #
0:12:07 > 0:12:11So your question was, what planets are near us in space?
0:12:11 > 0:12:13And I think we've answered it.
0:12:13 > 0:12:17We've discovered there are eight planets in our solar system.
0:12:17 > 0:12:22The further a planet is from the Sun, the longer it takes to go around it.
0:12:22 > 0:12:27Earth, is the third from the Sun and its journey takes one whole year!
0:12:27 > 0:12:32Planets are all different sizes, some are much bigger than Earth.
0:12:32 > 0:12:35And they're shaped like massive colourful balls!
0:12:35 > 0:12:37So I hope that's answered your question.
0:12:37 > 0:12:40BOTH: Thanks, Nina, bye!
0:12:40 > 0:12:41You're welcome, bye!
0:12:44 > 0:12:48If you want to know more about the science all around us,
