The present study aimed at investigating the development of children's conception of life, and putting the developmental study to the guide of curricular design. Children's conception of life divides into four successive steps, i.e., the conception of personified life, vitalism, mechanism, and the conception of life regarded as a system. This paper gives a brief illustration of elementary and secondary biology curriculum materials.
