Students discuss the functioning of the digestive system and the specific enzymes present. They observe the action of amylase on starch to identify characteristics of enzymes then perform an experiment on the effects of temperature on...

Students label main structures of the digestive system, describe each structure's function, and describe sequence of events involved in digestion.
