The video begins with a light-hearted introduction, inviting viewers to explore the journey of food through the human digestive system. It highlights that digestion is a process where large, insoluble food particles are broken down into smaller, water-soluble molecules for absorption into the bloodstream, ultimately providing energy to the body.

Stages of Digestion

1. Chewing: The first stage of digestion occurs when food is chewed, breaking it down into smaller pieces. Saliva, which contains enzymes, further assists in the breakdown of food particles.

2. Swallowing: Once chewed, the tongue helps push the food down the throat, entering the esophagus, also known as the food pipe.

3. Stomach Processing: The food travels down the esophagus to the stomach, where it resides for about four hours. The stomach releases acids and enzymes, including Pepsin, which specifically helps digest proteins. This stage also serves to kill harmful bacteria, protecting the body from illness.

4. Small Intestine: After the stomach, the food moves to the small intestine. Here, juices from the liver and pancreas further break down the food. The liver produces bile to digest fats, while the pancreas releases various enzymes for different types of food.

5. Absorption: In the small intestine, the broken-down particles are absorbed into the bloodstream and transported throughout the body. Any unabsorbed particles then move to the large intestine.

6. Large Intestine: The large intestine absorbs water and remaining nutrients, preparing waste material for elimination from the body. Interestingly, it also produces antibodies that enhance immunity.

Fun Facts: The video concludes with trivia about the digestive system, including a fun fact about the lining of the stomach turning red when someone blushes, paralleling changes in facial color.

The video encourages healthy eating and digestion, emphasizing the importance of maintaining good dietary habits for overall health. It wraps up with a playful farewell, inviting viewers to return for more fun facts in the future.

To try this digestion science experiment all you need are a few simple items you probably already have on hand:

• 1 banana

• 6-8 crackers

• 1-2 Tablespoon lemon juice or clear vinegar

• ziplock plastic bag

• old pair of tights or stockings

• plastic funnel

• 2 paper or styrofoam cups

• gloves

• scissors

• tray or container to contain the mess

  
  

But why does it look so different when it comes out? It comes out a different color, texture, and ….. well it smells. Basically, all the healthy ingredients have been absorbed by your body as the food was broken down and all that is left is the leftover, unused waste. In this fascinating and memorable human body science project children will learn and visualize what happens to the food they eat.

For our digetsive system model we are going to jump right to step 4 when the food is in the stomach. For the digestion experiment, students will put the food (banana and crackers) directly into the ziplock stomach. Seal it and have kids squish it, along with the stomach acid lemon juice or vinegar around.

• extra liquid will come out (in your body it would be absorbed)

• the waste will go out the bottom hole in the form and shape of poop

“I’m worried sick!”

“I have butterflies!”

Or why

You need to go the loo more regularly when you experience fear or nerves!

You may have a stomach-ache when you are worry, overthink or feel frustrated!

Being physically active can work wonders on your child’s digestive system, for instance:

• Regular exercise stimulates intestinal muscles to contract, thus regulating his bowel movements.

• Help relieve constipation by moving food through his digestive system.

• Better absorb nutrients.

• Feel better while exercising.

• Helps gas pass through the digestivetract quicker.

Maintaining regular physical activity will help prevent obesity, indigestion, and diverticulosis.

Being physically active can work wonders on your child’s digestive system, for instance:

• Encourage an active lifestyle.

• Discourage extended periods of inactivity e.g. long hours playing computer games or watching TV.

• Limit screen time.

• Get them involved with household chores, sports, and other games.

• Teach them the importance of being physically active.

As parents, it is important to keep two main things in mind:

1. Ensure your own lifestyle incorporates physical activity (children tend to follow their parents’ lifestyle)

2. Keep a part of your child’s daily schedule free for physical activity such as games, sports, or any form of unstructured play

As the well-known proverb goes “We do not inherit the Earth from our ancestors; we borrow it from our children.” We can meet our needs today without compromising the ability of future generations to meet theirs. And this can be done very simply. Whether we are meat-eaters or vegetarians, by thinking about the way in which we eat we can create the solutions that will safeguard the future of this, our one and only planet. And there’s even better news: what’s healthy for the planet is generally healthy for people too.

PEAR Do you know what mate? I just got a bit bored hanging around. So it’s great to come somewhere different - have a change of scene. You know?

CUCUMBER Aye. It’s good to travel. Where is it you’re from?

PEAR Outside. There. In the garden.

CUCUMBER Ah! You’re a local. I’m pretty local too. Well, Scottish anyway. D’you wanna see my tattoo?

PEAR Not really, that’s not a tattoo that’s a sticker, pal.

CUCUMBER Oh…

PEAR Aye. It says “Product of Scotland”.

CUCUMBER Scottish and proud.

PEAR Oh.

CUCUMBER Oh!

THE GREAT SPOON That sticker tells shoppers where you came from. You come from Scotland so you haven’t had to travel far. That’s better for the environment. And it means you’re fresher too.

PEAR I don’t have a sticker but then I literally came from the human’s garden.

THE GREAT SPOON Some foods can be produced easily in Scotland. Some can only grow in greenhouses that are warmer. You grew in a greenhouse in Inverclyde and were driven fifty miles to the supermarket. That chocolate bar travelled here too, but from far, far away.

CUCUMBER I’ve actually never seen a chocolate bar tree! Where do they grow?

CHOCOLATE BAR There’s no such thing as a chocolate bar tree! I come all the way from Switzerland – that’s where I was made.

CUCUMBER Oh…

CHOCOLATE BAR Milk from Europe was mixed with sugar from Brazil and my main ingredient, cocoa beans from Ghana. That’s in Africa. I’ve properly travelled.

THE GREAT SPOON Cocoa beans need humid weather - warm and wet. That’s why they are grown in parts of Africa. Like so many other foods, cocoa beans get from where they grew to where they were processed using many methods of transport: a truck to the port then a boat to Europe then another truck. The journey can take weeks!

PEAR And now you’re in Scotland! You’re a very well travelled bar of chocolate!

CHOCOLATE BAR 6,400 miles in total.

CUCUMBER That’s a lot of food miles.

PEAR Food miles? What are food miles?

THE GREAT SPOON Travelling by boat, plane and truck all use up energy. And that releases greenhouse gases that add to global warming.

PEAR And to think, I grew just out there in the garden not even 10 metres away!

THE GREAT SPOON The fewer food miles the better. Local foods like you add less to global warming. Cutting down on foods with lots of food miles can help the environment.

PEAR People can still enjoy them, just not so often.

CUCUMBER Here’s an idea. We could plant chocolate bar trees and grow our own chocolate bars in the garden!

PEAR Pal, have you no been listening to anything anyone’s been saying?

THE GREAT SPOON Ladies and gentlemen, knives and forks…Tonight… We quiz!

EVERYONE CHEERS

THE GREAT SPOON There are five food groups. Each of you belong to one of these groups! In order to find out which group you belong to we shall quiz like we have never quizzed before! If you think the riddle is about you then, shout “ME!” and name the type of food you think you are.

EGG Me!

THE GREAT SPOON We haven’t started yet, Egg. OK so riddle one…

“Butter me, toast me, enjoy me for my vitamin B”

DAIRY CHEERS

THE GREAT SPOON Riddle three…

“I can be one of your five a day. I’m stuffed to my green tips with vitamin C and iron. I look like a tree but luckily I don’t taste like one!”

EGG Broccoli, you look a bit like a tree.

BROCCOLI Me! Fruit and vegetables!

THE GREAT SPOON Spot on! Nice one, Broccoli. Fruit and vegetables are stuffed with vitamins and fibre that keep the digestive system working. Go and take a seat with the other fruit and veg!

FRUITS AND VEGETABLES CHEER

THE GREAT SPOON Riddle four…

“Spread me, bake with me, keep me in the fridge. Once upon a time my main ingredient was inside a cow!”

BEANS Beans!

THE GREAT SPOON Ummmm, no, Beans. You’re a protein…and you’ve never been inside a cow…

BEANS Beans…

BUTTER Me! Butter! Fats and oils!

THE GREAT SPOON Correct! Fats and oils store energy, keep people warm and protect organs like their hearts and lungs. But they’re best enjoyed in small portions! Pull up a seat with the other fats and Oils.

FATS AND OILS CHEER

THE GREAT SPOON Time for our last riddle:

“Cracking me is good to get the gold goo inside! Scramble me or boil me and gobble up my nutrients.”

BEANS Beans…

EGG Me! Me! Protein!

THE GREAT SPOON Correct! It is your time to shine, Egg. Eggs, beans and other proteins help build and repair bones, muscles, skin, and even blood! Congratul–

EGG CRACKS

EGG Sorry… I got overexcited.

THE GREAT SPOON Not to worry wee one.

PROTEINs CHEER

THE GREAT SPOON So, a healthy diet has lots of fruits and vegetables like broccoli. It has plenty of carbohydrates like bread potatoes, or pasta.

Some portions of protein should be eaten everyday - like eggs, meat or fish…or beans! And also it is important to eat some dairy - milk, cheese, or yoghurt. Or grab an alternative, like soy milk or oat milk.

It’s healthy to have a small amount of fat and oil. And a bit of sugar. Not too much though or your body might not work as well as it should!
