In Science, we have been learning about the digestive system this half term. Last week, we looked at mechanical and chemical digestion. To support this learning, we created a model of the digestive system using scissors and potato mashers (representing incisors and molars) to begin the mechanical digestion of bread. The bread and water (saliva- chemical digestion) was then squeezed down the sock (travelled the oesophagus) into a plastic bag (stomach) where the children added further water (fluids in the stomach-chemical digestion) and really mixed the bread and chemicals together. The bread then travelled into the tights (small and large intestines) where the children could see the water coming out of the tights (nutrients being absorbed into the blood stream) before getting to the end of the sock (rectum) and being excreted as poo.
