0:00:53 > 0:00:55# Oh, yeah! #
0:00:58 > 0:01:00Oh, hello there.
0:01:00 > 0:01:03I'm just seeing which one of these can jump the furthest.
0:01:03 > 0:01:05And, the yellow frog won!
0:01:05 > 0:01:08- "Yeah, yeah." - BEEPING
0:01:08 > 0:01:14Oh, I hear a beep, I see a flash, I wonder what they're going to ask.
0:01:14 > 0:01:18- Hi, Nina.- Hi!
0:01:18 > 0:01:20We have got a question for you.
0:01:20 > 0:01:25- We like playing jumping games. - How do we jump further?
0:01:25 > 0:01:28That's a great question. How can we jump further?
0:01:28 > 0:01:31I think we're going to have fun finding out.
0:01:31 > 0:01:34Why don't you come to my lab and we'll investigate?
0:01:34 > 0:01:38See you soon, Nina. Bye!
0:01:38 > 0:01:40Bye!
0:01:40 > 0:01:44Well, I'm going to need help and I know just who to ask.
0:01:44 > 0:01:47OK, Neurons, time to get to work.
0:02:01 > 0:02:03ALL: Neurons at the ready, Nina.
0:02:03 > 0:02:07OK, today's question is, "How can we jump further?"
0:02:07 > 0:02:10Which Neuron do you think will be most useful in helping us?
0:02:10 > 0:02:13- Me!- Me, me!- ME!- Me!
0:02:13 > 0:02:15Will it be fabulous Felix?
0:02:15 > 0:02:19I can help so very much if you need the sense of touch.
0:02:19 > 0:02:21Will it be beautiful Belle?
0:02:21 > 0:02:26I send messages to brain from ear. If there's a sound, I'll help you hear.
0:02:26 > 0:02:28Will it be lovely Luke?
0:02:28 > 0:02:30For looking and seeing, day or night,
0:02:30 > 0:02:32I'll help you with your sense of sight.
0:02:32 > 0:02:34Will it be awesome Ollie?
0:02:34 > 0:02:37If it's pongy or whiffy but you can't tell,
0:02:37 > 0:02:41- my messages help your sense of smell. - Or will it be baby Bud?
0:02:41 > 0:02:46Sour, salty, bitter or sweet, I'm your taste buddy whenever you eat!
0:02:49 > 0:02:52- It's Felix! - CHEERING
0:02:52 > 0:02:55Go Felix, go Felix, go Felix!
0:02:55 > 0:02:59Go Felix, go Felix!
0:02:59 > 0:03:03Marvellous. A little touch can mean so much, Nina.
0:03:03 > 0:03:06Today's question is, "How can we jump further?"
0:03:06 > 0:03:09Because jumping is something we feel,
0:03:09 > 0:03:12Felix, our touch Neuron, will be helping us.
0:03:12 > 0:03:15But stand by, Neurons, I may need help from all of you.
0:03:15 > 0:03:19I need to get the lab ready before the experimenters arrive.
0:03:21 > 0:03:24Amna loves helping to tidy the house.
0:03:24 > 0:03:25Rachael likes making pizza.
0:03:25 > 0:03:27Katie loves riding her scooter.
0:03:27 > 0:03:29We like jumping up and down.
0:03:29 > 0:03:32Some people can do really big jumps.
0:03:32 > 0:03:34How can we jump further?
0:03:34 > 0:03:37But they all want to know, "How can you jump further?"
0:03:37 > 0:03:39So for one day only
0:03:39 > 0:03:43Katie, Rachael and Amna become... The Experimenters.
0:03:45 > 0:03:49- Hi, guys.- Hi, Nina. - Welcome to my lab.
0:03:49 > 0:03:51And thank you for your great question,
0:03:51 > 0:03:53"How can we jump further?"
0:03:53 > 0:03:57To find out the answer, let's start by using our senses.
0:03:57 > 0:04:01Woop-woo, a senses experiment! We're ready, Nina.
0:04:01 > 0:04:06The first thing we have to do is work out what happens when we jump.
0:04:06 > 0:04:09So let's jump up and down and see what we can discover.
0:04:09 > 0:04:12Let's get jumping!
0:04:15 > 0:04:19Oh, you guys are really good at this! OK, stop there.
0:04:19 > 0:04:23- Jumping takes quite a lot of effort, doesn't it?- Yes, Nina.
0:04:23 > 0:04:27And that's because our bodies are quite heavy.
0:04:27 > 0:04:31So we have to push very hard to launch ourselves off the ground.
0:04:31 > 0:04:33But how can we jump further?
0:04:33 > 0:04:37Well, let's look more closely at jumping, with this special machine.
0:04:37 > 0:04:39Come over here, girls.
0:04:41 > 0:04:44When I pull the spring back and let it go,
0:04:44 > 0:04:49the machine will launch the ball so it jumps into the air.
0:04:49 > 0:04:52There's the ball in.
0:04:52 > 0:04:55Oh, oh...
0:04:55 > 0:04:59Oh! What happened there?
0:04:59 > 0:05:01It went up in the air.
0:05:01 > 0:05:04It did. The ball jumped straight up into the air,
0:05:04 > 0:05:06just like when we were jumping straight up.
0:05:06 > 0:05:10- But it didn't go very far, did it?- No.
0:05:10 > 0:05:14No, I will mark this with a lovely little red marker, like that.
0:05:14 > 0:05:19OK. Let's see what happens if we change the position of the launcher,
0:05:19 > 0:05:21so the ball jumps forward.
0:05:21 > 0:05:22OK.
0:05:27 > 0:05:30That's the ball inside. There we go.
0:05:30 > 0:05:34Oh! What happened there?
0:05:34 > 0:05:37- It still didn't go very far. - That's right.
0:05:37 > 0:05:40That's because it was so close to the ground
0:05:40 > 0:05:44that it hit the sand quite quickly. That's where it landed.
0:05:44 > 0:05:46Rachael, can you grab the ball for me?
0:05:46 > 0:05:50Let's try one more position. Thank you very much.
0:05:50 > 0:05:51Let's see what happens
0:05:51 > 0:05:56if we point the launcher so the ball jumps up AND forward.
0:05:56 > 0:05:57OK. Here we go.
0:05:57 > 0:06:00Ball in place.
0:06:00 > 0:06:01Here we go.
0:06:05 > 0:06:07Oh! Now, what happened that time?
0:06:07 > 0:06:10It went really far.
0:06:10 > 0:06:17So for a really big jump you need to jump up and forward at the same time!
0:06:17 > 0:06:18That's right, Bud.
0:06:18 > 0:06:23But there's something else we can do that can help us jump even further.
0:06:25 > 0:06:29'Where do you think we're going today?'
0:06:29 > 0:06:32Nina said we're going to experiment with jumping.
0:06:32 > 0:06:37Maybe we are going to bounce on a giant trampoline. Woo-hoo!
0:06:37 > 0:06:42'We've arrived. That's definitely not a trampoline.'
0:06:46 > 0:06:48So you asked, "How can we jump further?"
0:06:48 > 0:06:52and we've discovered that jumping up and forward
0:06:52 > 0:06:54can help us jump further.
0:06:54 > 0:06:58So we've come to this athletics stadium to meet Joseph. Hi, Joseph!
0:06:58 > 0:07:00- Hi, Joseph.- Hi, guys.
0:07:00 > 0:07:03Now, Joseph has won lots of national medals
0:07:03 > 0:07:05at a sport called the long jump.
0:07:05 > 0:07:08And that means he can jump very far.
0:07:08 > 0:07:10Can he jump as far as me?
0:07:10 > 0:07:14- Yes, Bud, amazingly, he can.- Aw-w!
0:07:14 > 0:07:16In the long jump,
0:07:16 > 0:07:21athletes like Joseph jump as far as they can into a special sandpit.
0:07:21 > 0:07:25And their jump always starts from a white line on the track,
0:07:25 > 0:07:28like this one. And Joseph will help us work out
0:07:28 > 0:07:30how we can jump further.
0:07:30 > 0:07:32So, can I ask you to stand at the white line
0:07:32 > 0:07:35and when you're ready, jump as far as you can?
0:07:39 > 0:07:44- Oh-ho-ho-ho! - LUKE:- Wow, that is a long jump!
0:07:44 > 0:07:49It was, Luke, but Joseph can jump even further than that.
0:07:49 > 0:07:53In the long jump, athletes are allowed a run before they jump.
0:07:53 > 0:07:55So what do you think running before you jump
0:07:55 > 0:07:59- would do to the length of the jump? - Make it longer.
0:07:59 > 0:08:01- Shall we try and see?- Yes!
0:08:01 > 0:08:02OK, this time do it again
0:08:02 > 0:08:05but run as fast as you can before you jump.
0:08:05 > 0:08:06No problem.
0:08:20 > 0:08:23NINA GIGGLES
0:08:23 > 0:08:28- Wow! That was much further! Well done, Joseph.- Thank you.
0:08:28 > 0:08:31So, taking the run-up did help him jump much further
0:08:31 > 0:08:35and that's because he was already moving really quickly,
0:08:35 > 0:08:39which helped to push him up and forward, making his jump longer.
0:08:39 > 0:08:45I'd do a much longer run-up. That way, I'd jump even further.
0:08:45 > 0:08:47Oh, interesting idea, Bud.
0:08:47 > 0:08:52I wonder if taking a longer run-up would make your jump longer.
0:08:52 > 0:08:55Let's do one more experiment to find out.
0:08:55 > 0:08:57Experimenters, it's your turn.
0:08:57 > 0:09:00You're all going to do three long jumps
0:09:00 > 0:09:03but the length of the run-up will change each time.
0:09:03 > 0:09:06First, let's start with the shortest run-up
0:09:06 > 0:09:09and I want you to run as fast as you can.
0:09:10 > 0:09:13Oh, good jump! Walk round and back.
0:09:13 > 0:09:15I'll measure that.
0:09:18 > 0:09:21Good jump! Excellent jump.
0:09:25 > 0:09:26Those were good jumps
0:09:26 > 0:09:30but were you running at your fastest speed when you jumped?
0:09:30 > 0:09:34- No, we only took a few steps. - That's right.
0:09:34 > 0:09:38You didn't have enough space to get up to your fastest running speed.
0:09:38 > 0:09:43OK, let's try this again but this time with a longer run-up.
0:09:43 > 0:09:48- LUKE:- Wow! they have a very long way to run this time, Nina.
0:09:48 > 0:09:50Woo-hoo! Well done!
0:09:55 > 0:09:59Well done, Katie! Good job.
0:09:59 > 0:10:00Woo-hoo-hoo-hoo!
0:10:00 > 0:10:04Those were also good jumps, but what happened?
0:10:04 > 0:10:07- I got tired. - I couldn't run any more.
0:10:07 > 0:10:11Gosh, The Experimenters are out of breath.
0:10:11 > 0:10:14You're right, Belle. The Experimenters are out of breath.
0:10:14 > 0:10:17We'll let you have a rest and a drink.
0:10:20 > 0:10:24On your last jump, you started off brilliantly.
0:10:24 > 0:10:26You reached your fastest running speed
0:10:26 > 0:10:29but because you had such a long way to go,
0:10:29 > 0:10:33it was really hard to keep running at your fastest so you slowed down.
0:10:33 > 0:10:36And because you'd slowed down,
0:10:36 > 0:10:40you didn't have as much speed to push your body up and forward.
0:10:40 > 0:10:42So I think we need to do it again.
0:10:42 > 0:10:45- Are you up for it?- Yeah!
0:10:45 > 0:10:48Your run-up will be longer than the first one,
0:10:48 > 0:10:50so you can reach your top speed,
0:10:50 > 0:10:52but shorter than the last one,
0:10:52 > 0:10:54so you don't get tired and slow down.
0:10:54 > 0:10:56Have you all got your breath back?
0:10:56 > 0:11:01- Yes!- OK, run as fast as you can. Go for it!
0:11:04 > 0:11:07Whoo! What a good jump! Well done!
0:11:12 > 0:11:15Woo-hoo! Good jump, Katie!
0:11:15 > 0:11:17Well done. High-five!
0:11:18 > 0:11:21Woo-hoo-hoo! Well done!
0:11:23 > 0:11:25Well done, Experimenters.
0:11:25 > 0:11:29This time you've all jumped much further.
0:11:29 > 0:11:32And that's because the run-up was just the right length -
0:11:32 > 0:11:36long enough to reach your fastest running speed when you jumped.
0:11:36 > 0:11:40That speed helped to push your body up and forward,
0:11:40 > 0:11:42making your jump longer.
0:11:42 > 0:11:44So to jump really far,
0:11:44 > 0:11:49you need to be running at your fastest speed when you jump.
0:11:49 > 0:11:51That's right, Bud.
0:11:51 > 0:11:55# Nina and the Neurons! #
0:11:55 > 0:11:58So your question was, "How can we jump further?"
0:11:58 > 0:12:00and I think we've answered it.
0:12:00 > 0:12:05When we jump, we bend our knees and launch ourselves into the air.
0:12:05 > 0:12:09If we jump up and forward at the same time, we can jump further.
0:12:09 > 0:12:13If we take a run-up before we jump, we can jump even further.
0:12:13 > 0:12:16But it can't be too long a run-up
0:12:16 > 0:12:19or we get out of breath and begin to slow down.
0:12:19 > 0:12:23We need to be running at our fastest speed when we jump
0:12:23 > 0:12:26to make sure we go really, really far.
0:12:26 > 0:12:30- So I hope that's answered your question.- Thanks, Nina.
0:12:30 > 0:12:33- Bye!- You're welcome. Bye!
0:12:35 > 0:12:39If you want to know more about the science all around us,
