P5 – 7 have linked with the Glasgow Science Centre to participate in their Body Works programme to learn how key body systems work. Today, we explored the digestive process.
To simulate digestion, we filled the mouth (a snack bag) with food (bananas and crackers) and stomach acid (orange juice + water). We mashed up the food to simulate our stomach muscles contracting and expanding to break down the food into smaller pieces. We then put the contents into our intestines (tights). The liquid nutrients passed through the small intestines (tights) into the body’s bloodstream (bowl). Water was reabsorbed back into the body through the large intestines. The waste food was then passed to the rectum (foot of the tights) and was excreted as faeces through the anus with our hands working as a muscle to aid the excretion of waste (hole in the toe of the tights).
It was a ‘guddly’ mess, but it certainly let us understand the process better.
Just look at Katie’s face! 😉
