Sydney Pierce, 15, a freshman at Springdale’s Central Junior High School, reacts Tuesday after pulling her arm out of the cannula placed in a beef steer at the Pauline Whitaker Animal Science Center in Fayetteville. Pierce is a student in the pre-advance placement biology class participating in the field study. The cannula gave the students access to the rumen, front part of the digestive system, in the steer.
