Hands on Science Sexto: Activity 3 - Intestines and Digestion

I don't think that many people think about how food gets chewed and mashed up in the digestive system.  This activity has the students being the muscles around the intestine physically digesting food, moving it along and finally doing a poo!  The activity focuses on the physical processes that enable food and nutrients to pass from the intestine into the blood stream.

This activity is connected to the Nutrition unit.  Ideas include the effect of saliva/liquid and chewing, cooking and how fast different component of food are absorbed.
