One at a time, each student lifts his or her hands up and then down.  

Explanation:

In a transverse wave, the vibrations are perpendicular to the direction of motion.

If the students are standing in a circle, the direction of motion is around the circumference.  

One direction perpendicular to the direction is up and down.

Thus, if each student raises their hands up and down, they are simulating a transverse wave.
