Hi, I'm Matthew.
00:00:09
Today on Experiment Time we're going to make a model of our stomach and our intestines,
00:00:20
parts of our digestive system.
00:00:26
So using a strong bag, some biscuits, a banana, a little water, some orange juice, a cup with
00:00:28
a hole in it and a stocking. We're going to show you what happens to food after we've
00:00:46
eaten it. We're going to show you a model of our intestines and stomach. What do you
00:00:53
think happens to food after we've chewed it and swallowed it? Let's find out. So, let's
00:00:58
say this bag is our stomach and this is our food. A little water for our saliva and some
00:01:05
orange juice for our gastric juice. There. So this is our model stomach. Okay, now I'm
00:01:31
going to break it down a bit more like this for about 30 seconds. So, this is the food
00:01:44
in our stomach. After the stomach, where does the food go? That's right, into the small
00:01:54
intestine. Look, I've got one here. It's a stocking. Now, can I have an assistant please?
00:02:01
Can you hold the stocking top open like this? Now I'm going to cut the stomach like this.
00:02:13
Oh wait, let's get a bowl because this will get messy. Now we're going to squeeze the
00:02:20
intestine a little to see how the small intestine works. Look, you can see the nutrients and
00:02:55
the water that our body needs. Okay, so now we're going to cut the knot and the food is
00:03:04
going to go into the large intestine where more water is absorbed. Then the food is going
00:03:27
to expel from our bodies like this. And this is the end of the food's journey. As you've
00:03:44
seen, this has only taken us a few minutes. How long do you think it takes in real life?
00:03:56
six to eight hours. So, that's how our digestive system works. Why not try it for yourselves?
00:04:02
See you later alligator.
