00:05If you've got a question and you don't know where to go,
00:08Ask Nina for some help, cause she's got a side show.
00:11She makes sense of her senses by helping all her fans,
00:14By doing her experiments with motions and with baths.
00:17Touch your tongue, fingers, eyes, ears, nose.
00:23Nina and her neurons find out what you need to know.
00:26Nina and her neurons find out what you need to know.
00:29Look, he helps us with our eyes and Felix with our touch.
00:32Ollie sniffs our smells and sends some bells he hears so much.
00:35But he's Ollie's brother, he helps us with our taste.
00:38Then he has little neurons and they're coming to your face.
00:41Touch your tongue, fingers, eyes, ears, nose.
00:47Nina and her neurons find out what you need to know.
00:50Nina and her neurons find out what you need to know.
00:53Oh, yeah!
00:57Oh, hello there!
00:59I'm just seeing which one of these could jump the furthest.
01:02And the yellow frog won!
01:05Yeah, yeah!
01:08I hear a beep, I see a flash, I wonder what they're going to ask.
01:15Hi, Nina!
01:16Hi!
01:17Hi!
01:17We have got a question for you.
01:20We like playing jumping games.
01:23How do we jump further?
01:25That's a great question.
01:26How can we jump further?
01:28I think we're going to have a lot of fun finding out.
01:31Why don't you come down to my lab and we'll investigate?
01:34See you soon, Nina!
01:36Bye!
01:38Bye!
01:39Well, I'm going to need some help to answer this one and I know just who to ask.
01:43OK, neurons, time to get to work!
02:01Neurons at the ready, Nina!
02:03OK, today's question is how can we jump further?
02:07Now, which neuron do you think will be most useful in helping us find the answer?
02:10Me!
02:11Me!
02:12Me!
02:12Me!
02:13Will it be Fabulous Felix?
02:15I can help so very much, if you need sense of touch!
02:19Will it be Beautiful Belle?
02:21I send messages to Grain from ear, if there's a sound, i'll help you hear.
02:25Will it be Lovely Look?
02:27For looking and seeing, day or night, I'll help you with your sense of sight.
02:32Will it be Awesome Ollie?
02:34If it's Polly or Whiffy, but you can't tell, my messages help your sense of smell.
02:39Will it be baby Bud?
02:40Sour? Salty? Bitter or sweet? I'm your taste buddy whenever you eat.
02:48It's Felix.
02:59Marvellous. A little touch can mean so much, Nina.
03:03Today's question is how can we jump further?
03:06Because jumping is something we feel, Felix, our touch neuron will be helping us today.
03:11But, standby neurons, I have a feeling I may need help from all of you.
03:15Right, I need to get the lab ready before the experimenters arrive.
03:21Anna loves helping to tidy the house.
03:23Rachel likes making pizza.
03:25Katie loves riding her scooter.
03:27We like jumping up and down. Some people can do really big jumps.
03:32How can we jump further?
03:33But they all want to know how can we jump further?
03:37So today, for one day only, Katie, Rachel and Amna become the experimenters!
03:44Hi guys!
03:46Hi, Nina!
03:48Welcome to my lab and thank you for your great question, how can we jump further?
03:53To find out the answer, let's start by using our senses.
03:56Whoop-whoop! A senses experiment!
03:59We're ready, Nina!
04:01The first thing we have to do is work out what happens when we jump.
04:06So let's jump up and down and see what we can discover.
04:09Let's get jumping!
04:11That's it, go for it!
04:14Oh, you guys are really good at this!
04:16Oh, you stop there!
04:19Jumping takes quite a lot of effort, doesn't it?
04:21Yes, Nina!
04:23And that's because our bodies are quite heavy.
04:27So we have to push very hard to launch ourselves off the ground.
04:30But how can we jump further?
04:33Well, let's look more closely at jumping with this special machine.
04:37Come over here, girls.
04:41When I pull the spring back and let it go, the machine will launch the ball so it jumps into
04:47the air.
04:49There's the ball in.
04:52Whoop-whoop!
04:56Ha-ha-ha!
04:57What happened there?
04:59It went up in the air!
05:01It did! The ball jumped straight up into the air, just like when we were jumping straight up.
05:06But it didn't go very far, did it?
05:09No.
05:09No, I will mark this with a lovely little red marker like that.
05:14OK, let's see what happens if we change the position of the launcher so the ball jumps forward.
05:21OK.
05:27That's the ball inside, there we go.
05:30Oh!
05:31Ha-ha-ha!
05:32What happened there?
05:33It still didn't go very far.
05:36That's right, and that's because it was so close to the ground that it hit the sand quite quickly.
05:41That is where it landed.
05:43Rachel, can you grab the ball for me and bring it back to the beginning?
05:46Let's try one more position.
05:48Thank you very much.
05:50Let's see what happens if we point the launcher so the ball jumps up and forward.
05:55OK, here we go.
05:57Ball in place.
06:00Here we go.
06:04Oh-ho-ho!
06:06Now what happened that time?
06:07It went really far.
06:10So for a really big jump, you need to jump up and forward at the same time.
06:16That's right, Bud.
06:17But there's something else we can do that can help us jump even further.
06:26Hmm...
06:26Where do you think we're going today?
06:29Nina said we're going to experiment with jumping.
06:31Maybe we're going to bounce on a giant trampoline!
06:35Woo-hoo!
06:37Woo-hoo!
06:37But we've arrived.
06:38That's definitely not a trampoline.
06:45So you asked how can we jump further, and so far we've discovered that jumping up and forward can help
06:52us jump further.
06:53So we've come to this athletic stadium to meet Joseph.
06:57Hi, Joseph.
06:58Hi, Joseph.
06:59Hi, Joseph.
06:59Hi, guys.
07:00Now, Joseph has won lots of national medals at a sport called the long jump.
07:05And that means he can jump very far.
07:08Can he jump as far as me?
07:10Yes, Bud.
07:11Amazingly, he can.
07:13Aww!
07:14In the long jump, athletes like Joseph jump as far as they can into a special sandpit.
07:21And their jump always starts from a white line on the track like this one.
07:26And Joseph's going to help us work out how we can jump further.
07:29So, Joseph, can I ask you to stand at the white line?
07:32And when you are ready, jump as far as you can.
07:38Oh!
07:40Wow!
07:41That is a long jump.
07:44It was, Luke.
07:45But Joseph can jump even further than that.
07:49In the long jump, athletes are allowed a run before they jump.
07:52So what do you think running before you jump would do to the length of the jump?
07:56Make it longer.
07:58Shall we try and see?
07:59Yes.
08:00OK, Joseph, this time, can you do it again, but run as fast as you can before you jump?
08:05No problem.
08:19Oh.
08:21Oh!
08:21Oh!
08:23Wow!
08:24That was much further!
08:25Well done, Joseph.
08:27So, taking the run up did help Joseph jump much further.
08:31And that's because he was already moving really quickly, which helped to push him up and forward, making his jump
08:38longer.
08:39I do a much longer run-up! That way I jump even further!
08:45Whoa, interesting idea, bud. I wonder if taking a longer run-up would make your jump longer.
08:51Let's do one more experiment to find out.
08:53Good. Experimenters, it's your turn. You're all going to do three long jumps, but the length of the run-up
09:01will change each time.
09:03First of all, let's start with the shortest run-up, and I want you to run as fast as you
09:07can.
09:09Oh, good jump! Walk round and back. Measure that.
09:18Good jump! Excellent jump!
09:25Those were good jumps, but where are you running at your fastest speed when you jumped?
09:30No, we only took a few steps.
09:32That's right! You didn't have enough space to get up to your fastest running speed.
09:38OK, let's try this again, but this time with the longer run-up.
09:42Wow! They have a very long way to run this time, Nina!
09:47Woo-hoo! Well done!
09:54Well done, Katie! Good job!
09:58Woo-hoo-hoo! Those were also good jumps, but what happened?
10:04I got tired.
10:05I couldn't run any more.
10:07Gosh! The experimenters are out of breath!
10:10You're right, Belle. The experimenters are out of breath.
10:14We'll let you have a rest and a drink.
10:20On your last jump, you started off brilliantly.
10:24You reached your fastest running speed, but because you had such a long way to go,
10:29it was really hard to keep running at your fastest, so you slowed down.
10:33And because you slowed down by the time you jumped,
10:36you didn't have as much speed to push your body up and forward.
10:40So I think we need to do it again. Are you up for it?
10:43Yeah!
10:44This time, your run-up will be longer than the first one,
10:47so that you can reach your top speed,
10:49but it'll be shorter than the last one,
10:52so that you don't get tired and slow down.
10:54So, have you all got your breath back?
10:56Yes!
10:58OK, run as fast as you can. Go for it!
11:03Woo-hoo! What a good jump! Well done!
11:12Woo-hoo! Good jump, Katie! Well done! High five!
11:17Woo-hoo-hoo-hoo! Well done!
11:23Well done, experimenters!
11:25This time, you've all jumped much further,
11:28and that's because the run-up was just the right leg.
11:32It was long enough so you could reach your fastest running speed when you jumped.
11:36That speed helped to push your body up and forward,
11:40making your jump longer.
11:41So, to jump really far,
11:44you need to be running at your fastest speed when you jump!
11:49That's right, bud.
11:50No!
11:55So, your question was, how can we jump further?
11:58And I think we've answered it.
12:00When we jump, we bend our knees and launch ourselves into the air.
12:04If we jump up and forward at the same time, we can jump further.
12:09And if we take a run-up before we jump, we can jump even further.
12:13But it can't be too long a run-up, or we get out of breath and begin to slow down.
12:19We need to be running at our fastest speed when we jump
12:23to make sure we go really, really fast!
12:26So, I hope that's answered your question.
12:28Thanks, Nina. Bye!
12:31You're welcome. Bye!
