0:01:05 > 0:01:07# Oh yeah! #
0:01:08 > 0:01:11- Hi, everyone! - ALL: Hi, Nina!
0:01:11 > 0:01:16Now, today we're going to find out how much sugar is in food.
0:01:16 > 0:01:20I've got some leftovers from my lunch - there's some fish,
0:01:20 > 0:01:25some dried banana, and some jelly bears which were a special treat!
0:01:25 > 0:01:29You can't tell how much sugar's in each just by looking,
0:01:29 > 0:01:33so I need something else to help me, and I have just the thing.
0:01:33 > 0:01:38In these tubes is a chemical called potassium chlorate,
0:01:38 > 0:01:42and we have to be careful, because when it mixes with sugar,
0:01:42 > 0:01:47something very unusual happens! So, let's try our fish first.
0:01:47 > 0:01:51Now, do we think there's any sugar in this fish?
0:01:51 > 0:01:53ALL: No!
0:01:53 > 0:01:55Well, let's see!
0:01:55 > 0:01:58OK, I'm just gonna pop it into our test tube... Oh!
0:01:58 > 0:02:02I'll just need the stirring rod, Gaby.
0:02:05 > 0:02:06Oh!
0:02:06 > 0:02:09There's no sugar in fish, and we know that
0:02:09 > 0:02:11because nothing happened! Fantastic!
0:02:11 > 0:02:14We're moving on to the dried banana.
0:02:16 > 0:02:19Do you think there's any sugar in here?
0:02:19 > 0:02:21ALL: No!
0:02:21 > 0:02:24Well, I'm not sure. Let's have a look.
0:02:26 > 0:02:27Oh!
0:02:29 > 0:02:33Brilliant! There must have been sugar in the dried banana,
0:02:33 > 0:02:37cos when it mixed with the chemical, it went up in flames!
0:02:37 > 0:02:43Now, last but not least, let's try the jelly bear!
0:02:43 > 0:02:46Do we think there's sugar in the jelly bear?
0:02:46 > 0:02:48ALL: Yes!
0:02:48 > 0:02:51I think you're right, so I might stand back, OK?
0:02:51 > 0:02:54Go on, jelly bear!
0:02:54 > 0:02:57Oh, here it goes!
0:02:57 > 0:02:58Woo!
0:03:02 > 0:03:04It's burning brightly, isn't it?
0:03:04 > 0:03:07ALL: Yeah!
0:03:07 > 0:03:12Isn't that brilliant? There must be loads of sugar in the jelly bear!
0:03:12 > 0:03:14Oh! It's stopped!
0:03:14 > 0:03:17After all that, it's stopped!
0:03:17 > 0:03:20The jelly bear burned really brightly,
0:03:20 > 0:03:22and it lasted longer than the banana,
0:03:22 > 0:03:27so that tells us that the jelly bear definitely contains the most sugar.
0:03:27 > 0:03:31We know sugar's bad for our teeth, don't we?
0:03:31 > 0:03:32ALL: Yes!
0:03:32 > 0:03:36- So no more jelly bears for me! - APPLAUSE
0:03:36 > 0:03:40ALARM BEEPS
0:03:40 > 0:03:45I hear a beep, I see a flash, I wonder what they're going to ask?
0:03:51 > 0:03:56Hi, Nina, I'm Millie. I've got a question for you.
0:03:56 > 0:03:58Why do we need to eat?
0:03:58 > 0:04:02Oh, that's a great question, Millie. Why do we need to eat?
0:04:02 > 0:04:05We like eating because food tastes good,
0:04:05 > 0:04:08but why do we actually NEED to eat? Oh!
0:04:08 > 0:04:11Tell you what, I'll meet you at the shops.
0:04:11 > 0:04:15- That'll be a good place to start. - Thanks, Nina, see you soon. Bye!
0:04:15 > 0:04:16Bye!
0:04:16 > 0:04:19I'm going to need some help to answer this one,
0:04:19 > 0:04:24and I know just who to ask. OK, Neurons, time to get to work!
0:04:39 > 0:04:41ALL: Neurons at the ready, Nina!
0:04:41 > 0:04:44Today's question is, why do we need to eat?
0:04:44 > 0:04:48Which Neuron will be most useful in finding the answer?
0:04:48 > 0:04:51ALL: Me! Me! Me!
0:04:51 > 0:04:54Will it be fabulous Felix?
0:04:54 > 0:04:58I can help so very much if you need the sense of touch.
0:04:58 > 0:05:02- Will it be beautiful Belle? - I send messages to brain from ear,
0:05:02 > 0:05:05if there's a sound, I'll help you hear.
0:05:05 > 0:05:06Will it be lovely Luke?
0:05:06 > 0:05:09For looking and seeing, day or night,
0:05:09 > 0:05:12I'll help you with your sense of sight.
0:05:12 > 0:05:15- Awesome Ollie? - If it's pongy or whiffy,
0:05:15 > 0:05:18but you can't tell, my messages help your sense of smell.
0:05:18 > 0:05:20Or baby Bud?
0:05:20 > 0:05:22Sour, salty, bitter or sweet,
0:05:22 > 0:05:25I'm your taste buddy whenever you eat!
0:05:28 > 0:05:32- Hee-hee!- It's Ollie and Bud!
0:05:32 > 0:05:34ALL: # Go Ollie, Go Bud!
0:05:34 > 0:05:36# Go Ollie, Go Bud!
0:05:36 > 0:05:38# Go Ollie, Go Bud!
0:05:38 > 0:05:39# Go Ollie! #
0:05:39 > 0:05:42Yippee! It's you and me, sis!
0:05:42 > 0:05:45Stand by for a taste and smell-a-thon!
0:05:45 > 0:05:49Thanks. The question is, why do we need to eat?
0:05:49 > 0:05:52Because food is something we taste and smell,
0:05:52 > 0:05:55Bud and Ollie will help us. But stand by,
0:05:55 > 0:05:57I may need help from all of you.
0:05:59 > 0:06:02OK, let's go!
0:06:23 > 0:06:27Millie's question is about eating - scrummy, runny food,
0:06:27 > 0:06:30crunchy, munchy food, and yummy messy food,
0:06:30 > 0:06:35so today, for one day only, Millie, David and her mum become...
0:06:35 > 0:06:36The Experimenters!
0:06:38 > 0:06:41That's me got my basket, now all I need to do
0:06:41 > 0:06:45is find Millie with her mum and her friend David.
0:06:45 > 0:06:48- ALL: Hi, Nina! - Hi, Millie! Hi, David!
0:06:48 > 0:06:51And hi, Mum! I see you've got a list of shopping to do!
0:06:51 > 0:06:54Yes, it takes a lot of food to feed this lot!
0:06:54 > 0:06:56Oh! I love eating too,
0:06:56 > 0:07:00and, Millie, your question was, why do we need to eat?
0:07:00 > 0:07:03- Why do you want to know? - Mum's always telling me
0:07:03 > 0:07:07it's important to eat all my dinner and I want to know why.
0:07:07 > 0:07:12The first thing we need to do is find out more about what we eat.
0:07:12 > 0:07:14Mum, carry on shopping,
0:07:14 > 0:07:17and Millie and David, will you help me?
0:07:17 > 0:07:19- BOTH: Yeah! - Let's go!
0:07:22 > 0:07:25We don't have much time to get what I need,
0:07:25 > 0:07:28so let's get moving!
0:07:28 > 0:07:30Can I have some cheese, please?
0:07:31 > 0:07:34Oh! I love shopping!
0:07:34 > 0:07:38Seeing all the yummy food makes me want to taste everything!
0:07:44 > 0:07:47Wow! Look at all that fabulous fruit!
0:07:47 > 0:07:52- So many beautiful colours!- You want to reach out and touch them!
0:07:55 > 0:07:59Oh, check out these potatoes, guys!
0:07:59 > 0:08:03- What is your favourite way to eat them?- Mashed and fluffy!
0:08:03 > 0:08:07- Baked potatoes from the oven! - Oh, that sounds lovely!
0:08:07 > 0:08:11You can do both, and also chop them, and that makes?
0:08:11 > 0:08:12BOTH: Chips!
0:08:12 > 0:08:15That's right! But no chips for us today,
0:08:15 > 0:08:17we've got to search for what I need.
0:08:19 > 0:08:22Oh, look, guys! Cheese!
0:08:22 > 0:08:25Oh! Cheese! Yummy!
0:08:25 > 0:08:27Cheese has lots of calcium in it,
0:08:27 > 0:08:30- and what's calcium's good for? - Teeth.
0:08:30 > 0:08:32It's also good for your bones.
0:08:32 > 0:08:36- Get some of that, Nina!- Sorry, cheese isn't on the list!
0:08:36 > 0:08:38I'm looking for something else
0:08:38 > 0:08:41which I think might be over this way.
0:08:44 > 0:08:47At last! This is just what I've been looking for -
0:08:47 > 0:08:50the delicious nuts and seeds.
0:08:50 > 0:08:53Can you pass me the sunflower seeds?
0:08:53 > 0:08:58Thank you very much! Well, after all that, this is all I need.
0:08:58 > 0:09:02- Oh, and it looks like your mum's finished as well.- Hi, guys!
0:09:02 > 0:09:08- Hi, Mum!- Hi! Oh, look at all this shopping you've got!
0:09:08 > 0:09:10Now, let's have a closer look
0:09:10 > 0:09:12to see what types of food you have.
0:09:12 > 0:09:19There's some fruit and veg, bread, cheese, yoghurts, meat,
0:09:19 > 0:09:22and fish as well. Oh! Oh, what's this?
0:09:22 > 0:09:26"With ingredients to give a lovely, glossy coat"?
0:09:26 > 0:09:29You don't have your coats with you!
0:09:29 > 0:09:31No, Nina! It's food for the dog!
0:09:31 > 0:09:34And we've got cat food and fish food.
0:09:34 > 0:09:38So you mean, there's not just food for people in here?
0:09:38 > 0:09:42There's food for pets as well? And I see you've bought
0:09:42 > 0:09:44another type of food - plant food?
0:09:44 > 0:09:47Yes, plants need feeding too, Nina!
0:09:47 > 0:09:49From Mum's basket, we've found out
0:09:49 > 0:09:52that we eat lots of different types of food.
0:09:52 > 0:09:55But it's not just people that need food.
0:09:55 > 0:09:59All living things need food, too.
0:09:59 > 0:10:02But we still don't know why, so we should pay for this
0:10:02 > 0:10:05- and go back to the lab to find out. - ALL: Yeah!
0:10:08 > 0:10:10I wonder where they are?
0:10:12 > 0:10:15Sorry we're late, we had to put petrol in the car.
0:10:15 > 0:10:18That's OK, no worries at all. You see,
0:10:18 > 0:10:21petrol is like food for your car. It's a fuel,
0:10:21 > 0:10:26and you put fuel into something to give it energy to make it work.
0:10:26 > 0:10:28- What do we use? - BOTH: Food!
0:10:28 > 0:10:34Exactly! So let's find out how food gives us energy.
0:10:34 > 0:10:38I bought some sunflower seeds - mm, they're great as a healthy snack...
0:10:38 > 0:10:41..and I also happen to have with me
0:10:41 > 0:10:44a fan and a radio. So, let me see if the radio works.
0:10:44 > 0:10:47SILENCE
0:10:47 > 0:10:48- Hear anything? - BOTH: No.
0:10:48 > 0:10:52Oh! There's no batteries in the radio!
0:10:52 > 0:10:54Batteries have chemicals
0:10:54 > 0:10:58that give out energy to make things work. Without batteries,
0:10:58 > 0:11:02we need something else to make the radio work,
0:11:02 > 0:11:06- like these!- Sunflower seeds? - Yes, sunflower seeds!
0:11:06 > 0:11:10How can sunflower seeds make the fan move?
0:11:10 > 0:11:12I'm just going to...
0:11:12 > 0:11:17put a nice big pile of sunflower seeds on the tripod.
0:11:17 > 0:11:22Lovely. Now, I need to put my goggles on for the next bit...
0:11:22 > 0:11:27and I'll keep a glove handy. I'm just gonna put my blowtorch on.
0:11:27 > 0:11:30Woo-hoo!
0:11:36 > 0:11:39There we go.
0:11:39 > 0:11:43So, I'll just pop my glove on...
0:11:43 > 0:11:48and move this underneath our fan.
0:11:49 > 0:11:52Now, let's see what happens.
0:11:52 > 0:11:55- Oh! Look at that! - SHE LAUGHS
0:11:55 > 0:12:00Would you look at that? The fan has started to work!
0:12:00 > 0:12:04The seeds are giving loads of energy to the fan to make it work!
0:12:04 > 0:12:06Let's try the radio.
0:12:06 > 0:12:08MUSIC PLAYS
0:12:09 > 0:12:11BELLE: I can hear the radio!
0:12:11 > 0:12:16The seeds are giving the radio energy and making it work!
0:12:16 > 0:12:20- FELIX:- Very impressive, Nina. - Food is so cool!
0:12:20 > 0:12:22Not only does it taste nice,
0:12:22 > 0:12:26but it has loads of energy inside it, too!
0:12:26 > 0:12:30That's brilliant, isn't it? So our food does have energy in it,
0:12:30 > 0:12:33and that made the fan and the radio work,
0:12:33 > 0:12:37and it's how our bodies work. That's why we need to eat.
0:12:37 > 0:12:41Food is our fuel. Without it, we wouldn't have any energy.
0:12:46 > 0:12:49So, you asked, why do we need to eat?
0:12:49 > 0:12:53We found out most things need fuel to give them energy to work,
0:12:53 > 0:12:57and humans need to eat, because food is OUR fuel.
0:12:57 > 0:13:00Eat lots of healthy food to give you
0:13:00 > 0:13:02energy so you can do fun things!
0:13:02 > 0:13:03ALL: Thanks, Nina!

0:13:50 > 0:13:56My favourite was when Nina showed us how food has lots of energy in it!
0:13:56 > 0:13:57I've had a brilliant day,
0:13:57 > 0:14:00especially when the radio came on!
0:14:00 > 0:14:02That was fab!
0:14:02 > 0:14:06We've had a sensational time. I hope you've enjoyed it.
