We have been learning about the digestive system in Science, and the children have found this a fascinating topic. We sparked even more interest with this very messy and hands-on experiment to help them understand the processes continually going on inside us - mostly without us even knowing it!
Accompanied by a great deal of "Yuk!" and "Ugh!" this experiment showed the journey of crackers and bananas through the stomach (a bag which had to be squeezed), tights (playing the part of the small intestine), cups (in the role of the large intestine) and finally children all had a turn pushing the waste through a hole in the cup - excretion. One of the children commented, "This is the best lesson ever!" and one declared Science was his "absolute favourite, it's the best!" All the children are now able to describe each organ's role and the order in which they form the digestive system.
