The Digestive System

 In this activity, students were learning about the different stages of digestion.  First, students were asked to place a cracker in their mouth for 3 minutes.  Within that time, the cracker disappeared due to the saliva.  Students then mimicked the mouth by using a fork (teeth) and water (saliva) to break down the food creating a suspension.  Lastly, students transferred the suspension to a plastic bag which was designed to mimic the stomach and turn the suspension into a solution.
