Monday, Sept. 25
Today we are doing an experiment that models the human digestive system. We’re learning about mechanical and chemical digestion. In the experiment mechanical digestion is represented by breaking an antacid tablet into small pieces and timing how long it takes to dissolve in vinegar. Vinegar is the chemical digestive process. Students will develop an experiment to model this and determine what happens if you change the food particle size. Make sure and read Activity 14 found on pages B-19 to B-21 and watch the video below.
