Today was out final lesson on Animals including Humans and we finished with a bang or may we say a splash.
Today we recreated the human digestive system using household products. Using a rolling pin to simulate teeth, tube for the esophagus, bag for the stomach and a pair of tights for the intestines we then recreated a typical day.
Starting off with breakfast we used the rolling pin to crush and grind our cereal which was washed down with a glass of orange juice. The children then acted as the muscles to aid in the digestion of food in the stomach.
Next we had a quick snack of biscuits and another quick drink which was shortly followed by dinner consisting of a sandwich, crisps and yet another drink. We all then get a little hungry after a hard day of schooling and we had a few more crisps and few more biscuits followed by some juice. After each meal we had to grind down the food in the same manner our teeth work which is then taken down the esophagus into the stomach.
Next the food moved through to our large intestine which uses muscles to push the food through and onto the small intestine while all the time taking the nutrients out which are needed to help give us energy, help support growth and keep healthy.
The final process is that of excretion. The waste that our bodies can’t use are then expelled from our body for a one way trip down the toilet competing our journey through the digestive system.
