Station 1: Anatomy Posters (4) Station 4: Stethoscope, cups, water, timer

Station 2: Yarn, scissors, marker, ruler, tape Station 5: Disease Posters (5)
Station 3: Histology Posters (4) Station 6: Stool sample, Q-tip, test sheet

This is a station lab activity. There are 6 stations set up around the classroom. Each station will take
approximately 10-15 minutes.
Station 1: The Digestive System
Digestive System Anatomy – Using the “Digestive System Anatomy” chart, identify the organs or
parts of the organ labeled A-W in Table 1 below. If there are any that you cannot identify, use a
textbook or online resource. A smaller version of this chart is included here for later review.
