Learning about the Digestive System

P6DigestiveSystemOne of the Primary 6 topics this term was the human body. To start off the topic, we learned about digestion. As a fun way to learn how food travels through the human body, all the classes got together and got put into teams. Then the teachers told us what to do first, and we got started.

To begin with, one person from each group went up to a table in the middle of the playground, and on it various items had been placed. They got cornflakes, half a banana and a bowl. We were all told to mash the cornflakes and banana together in the bowl, to represent the food which would travel down the digestive system. Then we got a cup of water to pour in the bowl to represent saliva. We then poured the mixture from the bowl into a plastic bag, to represent the food traveling down the oesophagus into the stomach [plastic bag]. Then we went up to the table again to collect green coloured water, to represent bile, red coloured water to represent enzymes, and yellow coloured water to represent acid. Then we shook it all up.

P6DigestiveSystemAt that point, the food had turned into a sloppy yellow mush. For the final part of the activity, first we had to get a pair of tights and scissors. We cut a corner of the plastic bag, first making sure that our cornflakes-banana mush would fall directly into the pair of tights. The pair of tights was representing the large intestine. After all the mush had fallen into the tights, we held the tights over the bowl and squeezed. We squeezed all the water out. Then came the slightly disgusting bit. We cut open the tights and scraped out what was left of the cornflakes and banana. What was left was the colour of scrambled eggs and was a sort of paste. The paste was meant to represent poo.

After that we all went inside to wash our hands and then we were allowed to play outside in the playground until home time. Then we went home to tell our families all about it!
