1:00:05 > 1:00:08# If you've got a question and you don't know where to go
1:00:08 > 1:00:11# Ask Nina for some help Cos she's got a science show
1:00:11 > 1:00:15# She makes sense of her senses While helping all her fans
1:00:15 > 1:00:18# By doing her experiments with potions and with bangs
1:00:18 > 1:00:20# Touch your tongue! Fingers!
1:00:20 > 1:00:23# Eyes. Eyes! Ears. Ears! Nose. Nose!

1:00:29 > 1:00:32# Luke he helps us with our eyes And Felix with our touch
1:00:32 > 1:00:36# Ollie helps our smells and sense And Belle she hears so much
1:00:36 > 1:00:38# Bud is Ollie's brother, he helps us with our taste
1:00:38 > 1:00:42# They're Nina's little neurons and they're coming to your place

1:00:54 > 1:00:55# Oh yeah! #
1:00:56 > 1:00:59One, two, three, four. One, two, three, four.
1:00:59 > 1:01:01Oh, hello there.
1:01:01 > 1:01:03I've just been doing my daily exercises,
1:01:03 > 1:01:06but I think I should have taken my lab coat off first.
1:01:06 > 1:01:09- I'm really hot now. - BEEPING
1:01:09 > 1:01:14I hear a beep, I see a flash, I wonder what they're going to ask?
1:01:19 > 1:01:21BOTH: Hi, Nina!
1:01:21 > 1:01:25- Hi, guys!- We've got a question for you.
1:01:25 > 1:01:29Why is exercise good for us?
1:01:29 > 1:01:31That's a great question.
1:01:31 > 1:01:35I love doing exercise but why is it so good for us?
1:01:35 > 1:01:39Why don't you come down to the lab and we'll do some experiments.
1:01:39 > 1:01:43BOTH: See you soon, Nina. Bye.
1:01:43 > 1:01:46I'm going to need some help and I know just who to ask.
1:01:46 > 1:01:49OK, Neurons, time to get to work.
1:01:53 > 1:01:55MUSIC
1:02:06 > 1:02:08ALL: Neurons at the ready, Nina.
1:02:08 > 1:02:11Today's question is, why is exercise good for us?
1:02:11 > 1:02:14Which Neuron do you think would be most useful
1:02:14 > 1:02:16in helping us find the answer?
1:02:16 > 1:02:19ALL: Me! Me! Me!
1:02:19 > 1:02:21Will it be fabulous Felix?
1:02:21 > 1:02:25I can help so very much if you need the sense of touch.
1:02:25 > 1:02:27Will it be beautiful Belle?
1:02:27 > 1:02:32I send messages to brain from ear. If there's a sound I'll help you hear.
1:02:32 > 1:02:33Will it be lovely Luke?
1:02:33 > 1:02:36For looking and seeing day or night,
1:02:36 > 1:02:38I'll help you with your sense of sight.
1:02:38 > 1:02:40Will it be awesome Ollie?
1:02:40 > 1:02:43If it's pongy or whiffy but you can't tell,
1:02:43 > 1:02:45my messages help your sense of smell.
1:02:45 > 1:02:47Or will it be baby Bud?
1:02:47 > 1:02:52Sour, salty, bitter or sweet, I'm your taste buddy whenever you eat.
1:02:55 > 1:02:57It's Felix!
1:02:57 > 1:02:59CHEERING
1:02:59 > 1:03:05ALL: Go Felix! Go Felix! Go Felix! Go Felix! Go Felix! Go Felix!
1:03:05 > 1:03:06Marvellous!
1:03:06 > 1:03:10A little touch can mean so much, Nina.
1:03:11 > 1:03:14Today's question is why is exercise good for us,
1:03:14 > 1:03:17and because we feel our bodies moving when we exercise
1:03:17 > 1:03:19Felix will be helping me today.
1:03:19 > 1:03:22But stand by Neurons, I may need help from all of you.
1:03:22 > 1:03:26I need to get the lab ready before the experimenters arrive.
1:03:28 > 1:03:31Katrina likes butterflies and Luke likes the planets.
1:03:31 > 1:03:35But they both want to know why exercise is good for us.
1:03:35 > 1:03:41So today, for one day only, Katrina and Luke become the experimenters!
1:03:43 > 1:03:46- Hi, guys! - BOTH: Hi, Nina!
1:03:46 > 1:03:49Welcome to my science lab. Come in.
1:03:49 > 1:03:53Now you asked, why is exercise good for us?
1:03:53 > 1:03:56It's a great question but why do you want to know?
1:03:56 > 1:03:59We love running around and playing sports.
1:03:59 > 1:04:04Everybody says it's good for us but we want to know why.
1:04:04 > 1:04:08Exercise is really important for our brilliant bodies,
1:04:08 > 1:04:12so for our first experiment, we're going to use our senses.
1:04:12 > 1:04:17ALL: Woo-hoo! A senses experiment! We're ready, Nina.
1:04:17 > 1:04:19We've taken our lab coats off
1:04:19 > 1:04:22because we're going to do some exercise
1:04:22 > 1:04:24and we don't want to get too hot.
1:04:24 > 1:04:28- What kind of exercise do you like doing?- Football and playing.
1:04:28 > 1:04:29Swimming and dancing.
1:04:29 > 1:04:33Oh, yes. The water feels good when you first jump in.
1:04:33 > 1:04:37And it makes a smashing splashing sound.
1:04:37 > 1:04:41Swimming, skipping and playing games like hide and seek
1:04:41 > 1:04:42are great ways to exercise.
1:04:42 > 1:04:48In fact, anything that makes us move our bodies is exercise.
1:04:48 > 1:04:51Things like walking, climbing the stairs, and...
1:04:51 > 1:04:53MUSIC
1:04:53 > 1:04:55..dancing!
1:04:55 > 1:04:58Come on, experimenters, let's move!
1:05:06 > 1:05:08That was great!
1:05:09 > 1:05:13You see, exercising can be really great fun.
1:05:13 > 1:05:17- Now, how did that make you feel? - Out of breath.
1:05:17 > 1:05:20That's right. Exercise makes our bodies work really hard
1:05:20 > 1:05:22so you get out of breath.
1:05:22 > 1:05:26Now we know exercise can be anything that makes us move.
1:05:26 > 1:05:29But how do we move, Nina?
1:05:29 > 1:05:33Well, when we move, we use things called muscles.
1:05:33 > 1:05:37This picture shows the bones in our arm.
1:05:37 > 1:05:41And these pink things are our muscles.
1:05:41 > 1:05:43We've got muscles all over our body
1:05:43 > 1:05:47and they work with our bones to help us move around.
1:05:47 > 1:05:50But how do the muscles move our bones?
1:05:50 > 1:05:53Well, let's use these to find out.
1:05:53 > 1:05:57These tubes are a bit like the bones in our arms
1:05:57 > 1:05:59and this thread is like the muscles.
1:05:59 > 1:06:03So, let's see what happens when we pull the thread.
1:06:03 > 1:06:07OK, have you got your arm? And pull the thread. Oh!
1:06:07 > 1:06:12- Ha-ha! So, what happened? - They popped up.
1:06:12 > 1:06:16Yeah, they moved the tubes. And that's a lot like how muscles work.
1:06:16 > 1:06:19They're joined onto our bones and they pull them
1:06:19 > 1:06:22up and down, like these threads.
1:06:22 > 1:06:25So, now we know that when we exercise,
1:06:25 > 1:06:28we use our muscles to move the bones in our bodies.
1:06:28 > 1:06:29And remember,
1:06:29 > 1:06:33moving our bones and muscles makes our bodies work really hard
1:06:33 > 1:06:37which keeps us fit and healthy. It's also great fun.
1:06:37 > 1:06:42But who needs to exercise and what type of exercise is best?
1:06:42 > 1:06:44We need to go somewhere to find out more,
1:06:44 > 1:06:48so get ready to cheer at the tops of you voices.
1:06:48 > 1:06:50- Let's go, experimenters. - ALL: Yeah!
1:06:53 > 1:06:59- Off we go for another adventure. - Nina says we've got to cheer.
1:06:59 > 1:07:04I bet I cheer the loudest. HURRAY!
1:07:04 > 1:07:06But cheer at what?
1:07:06 > 1:07:10I don't know, Felix, but it looks like we're about to find out.
1:07:10 > 1:07:14OK, experimenters, we know we should all do exercise
1:07:14 > 1:07:17because it's good for us but the exercise we choose
1:07:17 > 1:07:20depends on what we like and what we're able to do.
1:07:20 > 1:07:25Because everyone's different. Follow me. It's time to start cheering!
1:07:37 > 1:07:41Wow! Just look how fast those guys are going.
1:07:41 > 1:07:45Yes. I expect you need to be very fit indeed to play that game.
1:07:45 > 1:07:50They use wheelchairs cos their legs don't work quite like ours do.
1:07:50 > 1:07:53They're using sports wheelchairs to play basketball,
1:07:53 > 1:07:56which is great for exercise and learning teamwork.
1:07:56 > 1:08:01- So, let's cheer them on. - ALL: Yeah!
1:08:01 > 1:08:06Well done, Jo! What is it you like about playing wheelchair basketball?
1:08:06 > 1:08:10It's just so fun, Nina, and it helps me stay fit too.
1:08:10 > 1:08:14You use your arms a lot. Are the muscles there really strong?
1:08:14 > 1:08:17- Let me show you.- Oh! They are!
1:08:17 > 1:08:22Jo's arm muscles have grown bigger because she uses them all the time
1:08:22 > 1:08:24to play basketball.
1:08:24 > 1:08:27Wow! I wish I had arms as strong as that.
1:08:27 > 1:08:32- Shall we teach you some moves? - ALL: Yes please!- Grab a chair.
1:08:33 > 1:08:35Ho-ho-ho!
1:08:35 > 1:08:38There are lots of different wheelchairs.
1:08:38 > 1:08:41Some are used for everyday things like getting around
1:08:41 > 1:08:43and some, like these,
1:08:43 > 1:08:47are specially designed for playing sports like basketball.
1:08:47 > 1:08:50This is called a U-turn.
1:09:22 > 1:09:28- Oh! Yeah!- Yeah! - Thanks, Jo.- No problem, Nina.
1:09:28 > 1:09:31Phew! My arms are very tired.
1:09:31 > 1:09:35That's because your arm muscles have been working really hard.
1:09:35 > 1:09:37Team games are a great way to stay active.
1:09:37 > 1:09:41Everyone can find an activity to help them exercise
1:09:41 > 1:09:43and stay fit and healthy.
1:09:43 > 1:09:46There's one more reason exercise is good for us.
1:09:46 > 1:09:49- Let's go to the lab to find out what it is.- ALL: Yeah!
1:09:51 > 1:09:55Remember all the fun we had dancing and playing basketball?
1:09:55 > 1:09:57- Yes.- Yeah.
1:09:57 > 1:10:00That's because exercise makes us feel happier.
1:10:00 > 1:10:04In fact, scientists have proven that a healthy body
1:10:04 > 1:10:07gives us a healthy mind, which is another word for our brain.
1:10:07 > 1:10:12You see, when we exercise, it makes us feel more awake
1:10:12 > 1:10:16and our brains start to make something inside our heads,
1:10:16 > 1:10:18something called endorphins.
1:10:18 > 1:10:24- End of what?- Endorphins, Bud.- They're things that make us feel happy.
1:10:24 > 1:10:28OK, these exercise bikes are really special.
1:10:28 > 1:10:31And, Katrina, once we start peddling, we'll find out why.
1:10:31 > 1:10:34I'm just going to dim the lights.
1:10:34 > 1:10:38OK, Katrina, let's start peddling.
1:10:40 > 1:10:43Whoo-hoo-hoo! Faster!
1:10:44 > 1:10:45Brilliant!
1:10:45 > 1:10:49The lights have come on because they're wired up to these bikes.
1:10:49 > 1:10:53And when we peddle fast enough, the lights light up.
1:10:53 > 1:10:58When we exercise, our brains begin turning on the endorphins,
1:10:58 > 1:11:03just like these exercise bikes are turning on the lights.
1:11:03 > 1:11:05Endorphins make us feel happy.
1:11:05 > 1:11:09Well, I'm feeling happy just looking at all those pretty lights.
1:11:09 > 1:11:13- OK, Luke, would you like a go?- OK. - Okaydoke, swap over.
1:11:13 > 1:11:18Oh! These experimenters do love to exercise.
1:11:19 > 1:11:22Remember to keep peddling to keep those lights on, Luke.
1:11:24 > 1:11:26Exercise makes us happy
1:11:26 > 1:11:30because it switches on the happy endorphins in our brains.
1:11:30 > 1:11:34And the more we exercise, the better we feel.
1:11:34 > 1:11:37- So, are you feeling happy, Luke? - Yeah!
1:11:37 > 1:11:40Ha-ha! Me too. What a brilliant experiment.
1:11:45 > 1:11:49So, your question was, why is exercise good for us?
1:11:49 > 1:11:52I think we've answered it. We discovered that exercise
1:11:52 > 1:11:56can be anything that makes us move our bodies.
1:11:56 > 1:11:59To move our bodies, we need to use our muscles.
1:11:59 > 1:12:04When we different types of exercise, we use different types of muscles.
1:12:04 > 1:12:07We used our arm muscles to play wheelchair basketball
1:12:07 > 1:12:10and our leg muscles on the exercise bikes.
1:12:10 > 1:12:14Exercise is good for us because it keeps our bodies fit and healthy
1:12:14 > 1:12:17and also makes our minds feel happy
1:12:17 > 1:12:19because, when we exercise,
1:12:19 > 1:12:23our brains start to make something called endorphins,
1:12:23 > 1:12:25which make us feel happy inside.
1:12:25 > 1:12:28That's another reason why we should all do
1:12:28 > 1:12:30whatever exercise we can.
1:12:30 > 1:12:35- I hope that's answered your question.- BOTH: Thanks, Nina. Bye.
1:12:35 > 1:12:36Bye.
1:12:40 > 1:12:43Want to find out more about the science all around us?
1:12:43 > 1:12:48Go to the Nina section on the CBeebies website. Have fun!
1:12:48 > 1:12:53- Hearts beating.- Lungs breathing. - Fingers feeling.- Mouths eating.
1:12:53 > 1:12:54And don't forget your brain.
1:12:54 > 1:12:57# Brilliant bodies, brilliant bodies
1:12:57 > 1:13:00# Inside and ou-ou-out
1:13:00 > 1:13:03# Brilliant bodies, brilliant bodies

1:13:05 > 1:13:08# Our happy hands and bendy knees
1:13:08 > 1:13:10# Stretchy backs And noses that sneeze
1:13:10 > 1:13:15- # We all have brilliant bodies - Brilliant bodies!
1:13:15 > 1:13:17# Every part has a job to do
1:13:17 > 1:13:20# Even scabs and ear wax too

1:13:33 > 1:13:37# And don't forget to exercise. #
1:13:37 > 1:13:39Oh, I've had a brilliant day.
1:13:39 > 1:13:42I loved it when Nina was dancing.
1:13:42 > 1:13:44The music sounded great!
1:13:44 > 1:13:50I've had a fabby day! The wheelchair basketball was so cool.
1:13:50 > 1:13:54Oh, it's been such a great day, man.
1:13:54 > 1:13:57Watching the little lights on the exercise bikes
1:13:57 > 1:13:59getting brighter, made me so happy.
1:13:59 > 1:14:04Remember, everyone's body is different but they're all brilliant.
1:14:04 > 1:14:06- See you again soon. Bye.- ALL: Bye.
