During the first two years, students are introduced to exercises about practical life, such as spooning beans, pouring water, and polishing silver. These exercises satisfy the child's need to imitate adult behavior and increase their levels of independence. These exercises also lengthen attention span and aid in the development of fine motor coordination. As time goes by, practical life exercises evolve from care of self into care of others and the environment, which then can lead to activities such as science experimentation and discoveries.
