As education materials for service seminar, proposed are simple pendulum with circular disk, rocking semicircularcylinder, ring pendulum and bifilar suspension pendulum, which are very instructive to study physical pendulums.The isochronism of simple pendulum holds when initial angle is small, but breaks as it increases. This may be a statingpoint at the seminar for junior high school students. Rocking semi-circular cylinder works as roly-poly toy, when theposition of center of mass is below the center of geometry. Further mechanisms of pendulums will be revealed from modelanalysis and experiments for service seminar. The oscillation mechanisms used in various engineerings will be interestingitems for the students. The first seminar is reported in connection with the service learning for students of the department.
