P1 Science Day 3 – Poo

Today we looked at how our body makes us poo. We started off the lesson by eating a jam sandwich.

Miss Stevenson demonstrated what happens in our mouth by mashing a jam sandwich up with a little water (saliva) in a bowl.

We then saw the sandwich work its way down the Oesophagus into the Stomach. In the Stomach a little Acid was added (Vinegar) and the Stomach was squeezed to break down the food.

The sandwich then left the Stomach and went into the Intestines. It travelled through the Intestines and the Nutrients (water) squeezed through the wall of the Intestines (tights) into the body. The pupils squeezed the digested sandwich along the “Intestine” and finally at the end watched the “poo” arrive.
