As the children come to the end of the topic on the animals including humans, the children have been learning about the digestive system. How the teeth are the first process and one of the most important to the stomach and the intestines.
Today we learnt about stomach acid and how our stomach actually works. Taking a jar half filled with red food colouring we simulated the stomach filling with acid in the form of oil. We then added an effervescent tablet to start the stomach acids dissolving process. The children made predictions about what they thought may happen and then it was time to digest.

Dropping the tablet into the make shift stomach they were able to see the effects that take place within their own bodies. We then experimented with different size jars as not all stomachs are the same in size.

Next week the final stages of the digestive system.
