As well as having interactive exhibits, the centres provided workshops on topics such as the human body and magnetism, and laboratory areas where learners carried out experiments.
Yn ogystal ag arddangosfeydd rhyngweithiol, cynhaliodd y canolfannau weithdai ar bynciau fel y corff dynol a magnetedd, ac roedd ganddynt labordai lle gallai dysgwyr gynnal arbrofion.
