4L have enjoyed getting very messy (sorry grown ups) to create the digestive system. We used a bag, a pair of tights, biscuits, banana, orange juice and water, we mixed all of the food and drink together in a bag (the stomach), then we sent the contents in the bag through the tights (small intestine) we soaked up all of the nutrients with a paper towel (large intestine) finally we cut a hole in the bottom of the tights, for the poo to come out.
I’m sure if you ask your children, they will tell you how disgusting it was!
