Hello there. I am seeing how many times | 0:00:59 | 0:01:01 | |
I can bounce this ball. Here we go. | 0:01:01 | 0:01:03 | |
One, two, three, four... | 0:01:03 | 0:01:06 | |
BEEP | 0:01:06 | 0:01:08 | |
I hear a beep, I see a flash. I wonder what they're going to ask. | 0:01:08 | 0:01:12 | |
-BOTH: Hi, Nina! -Hi. | 0:01:15 | 0:01:17 | |
We've got a question for you. | 0:01:17 | 0:01:19 | |
Why is a ball so bouncy? | 0:01:19 | 0:01:21 | |
That's a great question. | 0:01:21 | 0:01:23 | |
Why are balls so bouncy? | 0:01:23 | 0:01:25 | |
Bouncing balls is great fun. But what makes them bounce? | 0:01:25 | 0:01:28 | |
Why not come down to my lab and we'll investigate? | 0:01:28 | 0:01:32 | |
BOTH: See you soon. Bye! | 0:01:32 | 0:01:33 | |
Bye. | 0:01:33 | 0:01:35 | |
Well, I'll need some help to answer this one. | 0:01:35 | 0:01:38 | |
And I know just who to ask. OK, Neurons, time to get to work! | 0:01:38 | 0:01:42 | |
ALL: Neurons at the ready, Nina. | 0:01:56 | 0:01:58 | |
OK. Today's question is, why are balls so bouncy? | 0:01:58 | 0:02:02 | |
Which Neuron will be most useful in helping us find the answer? | 0:02:02 | 0:02:06 | |
ALL: Me! | 0:02:06 | 0:02:08 | |
Will it be fabulous Felix? | 0:02:08 | 0:02:11 | |
I can help so very much if you need the sense of touch. | 0:02:11 | 0:02:15 | |
Will it be beautiful Belle? | 0:02:15 | 0:02:17 | |
I send messages from brain to ear. | 0:02:17 | 0:02:19 | |
If there's a sound I'll help you hear. | 0:02:19 | 0:02:22 | |
Will it be lovely Luke? | 0:02:22 | 0:02:23 | |

I'll help you with your sense of sight. | 0:02:26 | 0:02:28 | |
Will it be awesome Olly? | 0:02:28 | 0:02:30 | |
If it's pongy or whiffy, but you can't tell, | 0:02:30 | 0:02:33 | |
my messages help your sense of smell. | 0:02:33 | 0:02:35 | |
Or will be baby Bud? | 0:02:35 | 0:02:37 | |
Sour, salty, bitter or sweet, | 0:02:37 | 0:02:40 | |
I'm your taste buddy whenever you eat. | 0:02:40 | 0:02:43 | |
It's Luke! | 0:02:47 | 0:02:48 | |
CHEERING | 0:02:48 | 0:02:50 | |
ALL: Go, Luke, go, Luke, go, Luke, go, Luke, go, Luke. | 0:02:50 | 0:02:55 | |
Go, Luke! | 0:02:55 | 0:02:56 | |
Cool, Nina! I'll be looking out to help ya! | 0:02:56 | 0:02:59 | |
Today's question is, why are balls so bouncy? | 0:02:59 | 0:03:02 | |
As we can see a ball bounce, Luke, our sight Neuron, | 0:03:02 | 0:03:06 | |
will help us. | 0:03:06 | 0:03:07 | |
But stand by, Neurons, I have a feeling I may need help | 0:03:07 | 0:03:11 | |
from all of you. I must get the lab ready | 0:03:11 | 0:03:13 | |
before the experimenters arrive! | 0:03:13 | 0:03:15 | |
Connor likes playing in the garden. | 0:03:17 | 0:03:20 | |
Sarah-Louise likes dancing. | 0:03:20 | 0:03:22 | |
Balls is fun. | 0:03:22 | 0:03:24 | |
We like bouncing balls very high. | 0:03:24 | 0:03:27 | |
But they both want to know, why are balls so bouncy? | 0:03:27 | 0:03:31 | |
So, today, for one day only, Sarah-Louise and Connor | 0:03:31 | 0:03:34 | |
become The Experimenters! | 0:03:34 | 0:03:38 | |
Hi, guys! | 0:03:41 | 0:03:42 | |
BOTH: Hi, Nina! | 0:03:42 | 0:03:44 | |
Welcome to my lab and thank you for your great question, | 0:03:44 | 0:03:47 | |
why are balls so bouncy? | 0:03:47 | 0:03:49 | |
To find out the answer, let's start by using our senses. | 0:03:49 | 0:03:52 | |
ALL: Whoop-whoo! A senses experiment. | 0:03:52 | 0:03:55 | |
We're ready, Nina! | 0:03:55 | 0:03:57 | |
We have some balls here. | 0:03:57 | 0:03:58 | |
Let's give then a bounce and see what happens! | 0:03:58 | 0:04:01 | |
Let's bounce! | 0:04:01 | 0:04:04 | |
Yay! | 0:04:05 | 0:04:06 | |
Oh, I love that bouncy noise! | 0:04:06 | 0:04:09 | |
These balls are definitely bouncy. | 0:04:09 | 0:04:11 | |
But they bounce so fast | 0:04:11 | 0:04:13 | |
it's hard for us to see what happens. | 0:04:13 | 0:04:16 | |
Let's look at a ball bouncing slowly. | 0:04:16 | 0:04:18 | |
Look over here. | 0:04:18 | 0:04:20 | |
A special camera has taken these pictures | 0:04:20 | 0:04:23 | |
and then slowed them down so we can see what is going on. | 0:04:23 | 0:04:26 | |
Wow! When you slow things down, | 0:04:26 | 0:04:29 | |
you can see everything much better! | 0:04:29 | 0:04:31 | |
Can you see what happens to the bottom of the ball | 0:04:31 | 0:04:35 | |
-when it bumps onto the floor? -It goes flat. | 0:04:35 | 0:04:38 | |
Yes, the ball gets squashed when it bumps onto the floor. | 0:04:38 | 0:04:41 | |
But what happens next? | 0:04:41 | 0:04:43 | |
Does the ball stay squashed? | 0:04:43 | 0:04:45 | |
-No! -You're right. It only stays squashed for a moment. | 0:04:45 | 0:04:48 | |
So after it has bumped onto the floor | 0:04:48 | 0:04:51 | |
and been squashed, | 0:04:51 | 0:04:52 | |
it goes back into shape - | 0:04:52 | 0:04:54 | |
and it's this change of shape | 0:04:54 | 0:04:55 | |
that is a clue to find out how a ball bounces. | 0:04:55 | 0:04:58 | |
Let's take these balls back. | 0:04:58 | 0:05:01 | |
We will try to squash these balls like this. | 0:05:01 | 0:05:05 | |
Oh! It's quite hard. | 0:05:07 | 0:05:09 | |
How are you getting on? | 0:05:09 | 0:05:11 | |
It's really, really hard. | 0:05:11 | 0:05:13 | |
It is! Does it feel like the ball is pushing back against us? | 0:05:13 | 0:05:18 | |
-Yes! -That's exactly what's happening. | 0:05:18 | 0:05:20 | |
When a ball bumps onto the floor, it's squashed at the bottom, | 0:05:20 | 0:05:24 | |
then goes straight back into its round shape. | 0:05:24 | 0:05:27 | |
As the ball goes back into shape, it pushes against the floor. | 0:05:27 | 0:05:31 | |
It's this push that makes a ball bounce. | 0:05:31 | 0:05:34 | |
So, when a ball bumps onto the ground, | 0:05:34 | 0:05:37 | |
it gets squashed at the bottom. | 0:05:37 | 0:05:39 | |
But the ball goes straight back into shape! | 0:05:39 | 0:05:43 | |
Remember, Nina, we should be very careful | 0:05:43 | 0:05:45 | |
if we bounce balls inside. | 0:05:45 | 0:05:48 | |
You're right, Felix! | 0:05:48 | 0:05:50 | |
Why do balls bounce better on the playground than the grass? | 0:05:50 | 0:05:54 | |
Balls bounce better on the playground. | 0:05:54 | 0:05:56 | |
Let's do another experiment to find out more. | 0:05:56 | 0:05:59 | |
I know some expert ball bouncers who can help us. | 0:05:59 | 0:06:03 | |
Where do you think we're going today? | 0:06:05 | 0:06:07 | |
Maybe it's a playground. | 0:06:07 | 0:06:09 | |
Nina said we'll meet people who are experts at bouncing balls. | 0:06:09 | 0:06:14 | |
Then it has to be a playground! | 0:06:14 | 0:06:15 | |
Look, we've arrived! | 0:06:15 | 0:06:17 | |
This looks like a very different sort of playground. | 0:06:17 | 0:06:21 | |
So we want to find out why balls bounce better in the playground | 0:06:21 | 0:06:26 | |
than they do on grass. | 0:06:26 | 0:06:27 | |
We've come to this basketball court to find out why. | 0:06:27 | 0:06:30 | |
Basketball is a great sport | 0:06:30 | 0:06:32 | |
and the players have to bounce the ball a lot. | 0:06:32 | 0:06:35 | |
Yay! Hee-hee! | 0:06:41 | 0:06:45 | |
Wow! Look at how they bounce the ball! | 0:06:45 | 0:06:48 | |
That is really cool. | 0:06:48 | 0:06:50 | |
This basketball court is hard, like a playground, | 0:06:50 | 0:06:53 | |
and this mat is soft and spongy | 0:06:53 | 0:06:57 | |
like grass. | 0:06:57 | 0:06:58 | |
We will do an experiment to find out | 0:06:58 | 0:07:00 | |
how balls bounce on each of them. | 0:07:00 | 0:07:03 | |
You guys will drop the ball | 0:07:03 | 0:07:05 | |
from the line onto the floor | 0:07:05 | 0:07:08 | |
and we will measure how high they bounce. | 0:07:08 | 0:07:11 | |
First, let's find out what happens | 0:07:11 | 0:07:13 | |
when we drop a ball onto the hard floor. | 0:07:13 | 0:07:16 | |
Connor, go for it. | 0:07:16 | 0:07:19 | |
And...drop. | 0:07:19 | 0:07:22 | |
It dropped about there. | 0:07:22 | 0:07:24 | |
Let me just put a sticker on. | 0:07:24 | 0:07:26 | |
There we go. | 0:07:26 | 0:07:28 | |
And drop it. | 0:07:28 | 0:07:29 | |
I think it bounced about there. | 0:07:29 | 0:07:31 | |
Good dropping. | 0:07:31 | 0:07:34 | |
I think it bounced up to about there. | 0:07:34 | 0:07:36 | |
I think it came to about there. | 0:07:36 | 0:07:40 | |
And...drop it! | 0:07:40 | 0:07:42 | |
Oh, my goodness! | 0:07:42 | 0:07:44 | |
It just came to there. | 0:07:44 | 0:07:45 | |
Drop! | 0:07:45 | 0:07:47 | |
Oh! | 0:07:47 | 0:07:49 | |
Drop it! | 0:07:49 | 0:07:50 | |
I'm sure it went to there that time. | 0:07:50 | 0:07:54 | |
Drop it! | 0:07:55 | 0:07:56 | |
Hee-hee-hee! | 0:07:56 | 0:07:57 | |
It came to there. | 0:07:57 | 0:08:00 | |
Super work. | 0:08:00 | 0:08:01 | |
Well done, guys! | 0:08:02 | 0:08:04 | |
Did the balls bounce higher on the hard floor | 0:08:04 | 0:08:08 | |
or the soft floor? | 0:08:08 | 0:08:09 | |
The hard floor. | 0:08:09 | 0:08:10 | |
That's right. The balls bounced much higher | 0:08:10 | 0:08:13 | |
when they were dropped onto the hard floor than the soft floor. | 0:08:13 | 0:08:17 | |
The hard floor really squashes the ball. | 0:08:17 | 0:08:20 | |
When it goes back into shape, | 0:08:20 | 0:08:21 | |
it pushes against the hard floor and bounces really high. | 0:08:21 | 0:08:25 | |
The soft floor doesn't squash the ball as much, | 0:08:25 | 0:08:28 | |
so it can't bounce as much. | 0:08:28 | 0:08:30 | |
The harder we squash a ball, the more it bounces. | 0:08:30 | 0:08:33 | |
Let's see if the type of floor | 0:08:33 | 0:08:36 | |
makes a difference for playing basketball. | 0:08:36 | 0:08:39 | |
Our players will play some basketball | 0:08:39 | 0:08:41 | |
on the soft mats for us. Let's go. | 0:08:41 | 0:08:45 | |
-Hi, guys. -ALL: Hi. | 0:08:45 | 0:08:47 | |
Can you start playing basketball on these soft mats, please? | 0:08:47 | 0:08:53 | |
Oh! | 0:08:53 | 0:08:55 | |
-Oh, no, what is happening? -The ball is not bouncing very well. | 0:08:59 | 0:09:03 | |
You are right. This definitely proves | 0:09:03 | 0:09:06 | |
you need a hard floor to play basketball on. | 0:09:06 | 0:09:09 | |
That's because balls bounce higher on a hard floor, like a playground, | 0:09:09 | 0:09:14 | |
than a soft floor, like grass. | 0:09:14 | 0:09:16 | |
Some balls do not bounce as much as others. | 0:09:16 | 0:09:20 | |
Do you think this ball will bounce? | 0:09:20 | 0:09:22 | |
BOTH: No! | 0:09:22 | 0:09:23 | |
Well, let's see. | 0:09:23 | 0:09:25 | |
Ah, no. | 0:09:25 | 0:09:27 | |
SHE LAUGHS | 0:09:27 | 0:09:29 | |
Why does it not bounce? | 0:09:29 | 0:09:30 | |
That is a very good question. | 0:09:30 | 0:09:32 | |
Time for another experiment. | 0:09:32 | 0:09:35 | |
There are lots of types of ball, made of lots | 0:09:37 | 0:09:40 | |
of different things, | 0:09:40 | 0:09:41 | |
but we will look at balls with air in them. | 0:09:41 | 0:09:44 | |
Let's give these balls a bounce to make sure they're bouncy. | 0:09:44 | 0:09:49 | |
Go for it! Down and catch. | 0:09:49 | 0:09:52 | |
Good! | 0:09:52 | 0:09:54 | |
Are they bouncy? | 0:09:56 | 0:09:57 | |
Yes! | 0:09:57 | 0:09:59 | |
We can't see the air inside them, | 0:09:59 | 0:10:01 | |
but we can feel it. I'll show you. | 0:10:01 | 0:10:03 | |
Put that one here. | 0:10:03 | 0:10:05 | |
Thank you. | 0:10:05 | 0:10:06 | |
Just open this bit up here. | 0:10:06 | 0:10:08 | |
Can you hold your hands out for me, please? | 0:10:08 | 0:10:11 | |
Can you feel the air from inside the ball? | 0:10:11 | 0:10:14 | |
It feels like a balloon. | 0:10:14 | 0:10:16 | |
I love that sound! | 0:10:16 | 0:10:18 | |
SHE BLOWS | 0:10:18 | 0:10:19 | |
That's tickling my cheek! | 0:10:19 | 0:10:22 | |
Lots of balls have the inside them to help make them bouncy. | 0:10:22 | 0:10:26 | |
The basketballs were filled with air, too, like these clear balls. | 0:10:26 | 0:10:30 | |
What do you think will happen now we've let some air out of this ball? | 0:10:30 | 0:10:34 | |
Will it still bounce? | 0:10:34 | 0:10:36 | |
BOTH: No. | 0:10:36 | 0:10:37 | |
Let's try. | 0:10:37 | 0:10:39 | |
-Did it bounce? -BOTH: No. | 0:10:39 | 0:10:41 | |
You're right. | 0:10:41 | 0:10:43 | |
When the ball was full of air, it bounced really well. | 0:10:43 | 0:10:47 | |
Now it has less air in it, it hardly bounces at all. | 0:10:47 | 0:10:50 | |
Let's find out why. | 0:10:50 | 0:10:52 | |
We can't see air, | 0:10:52 | 0:10:54 | |
so I have filled these balls | 0:10:54 | 0:10:56 | |
with little white beads and we will pretend | 0:10:56 | 0:10:59 | |
the beads are air. | 0:10:59 | 0:11:01 | |
This ball is full of our pretend air. | 0:11:01 | 0:11:04 | |
This ball is only half-full. | 0:11:04 | 0:11:07 | |
We know that the harder it is to squash a ball, | 0:11:07 | 0:11:11 | |
the more it bounces. | 0:11:11 | 0:11:13 | |
Let's give these a squash and see what happens. | 0:11:13 | 0:11:17 | |
Try and give them a squash. | 0:11:17 | 0:11:19 | |
That's it. Have a good feel and a good push. | 0:11:19 | 0:11:22 | |
Oh! | 0:11:22 | 0:11:24 | |
Hm. Which ball was harder to squash? | 0:11:24 | 0:11:28 | |
The full ball. | 0:11:28 | 0:11:30 | |
Yes, if you squash a full ball, | 0:11:30 | 0:11:32 | |
it won't stay squashed | 0:11:32 | 0:11:34 | |
because the air inside will push it back out | 0:11:34 | 0:11:37 | |
and make the ball round again. | 0:11:37 | 0:11:39 | |
That is why it is bouncy. | 0:11:39 | 0:11:41 | |
But when you squash a half-full ball, | 0:11:41 | 0:11:44 | |
it stays squashed because it doesn't have enough air inside it | 0:11:44 | 0:11:49 | |
to push it back into shape so it can't bounce. | 0:11:49 | 0:11:52 | |
# Nina and the Neurons! # | 0:11:52 | 0:11:56 | |
Your question was, | 0:11:56 | 0:11:59 | |
why are balls so bouncy? I think we have answered it. | 0:11:59 | 0:12:02 | |
When a ball bumps to the ground, | 0:12:02 | 0:12:04 | |
it gets squashed at the bottom. | 0:12:04 | 0:12:06 | |
It pushes hard against the floor | 0:12:06 | 0:12:09 | |
and goes back into shape, and that is what makes it bounce. | 0:12:09 | 0:12:12 | |
Balls bounce much better on hard floors than soft floors. | 0:12:12 | 0:12:16 | |
Lots of balls have air inside them | 0:12:16 | 0:12:19 | |
