Drawingunderstanding teaching theory and practice of research, combined with small subject sciencecurriculum of basic idea and goal, this article theoretically constructed the basic model ofelementary school science understanding teaching, including the goal determination ofunderstanding, understanding of standards and evaluation, learning activities of theorganization, understand the learning evaluation of five parts. Next apply the pattern to theelementary school science grade three part ii the second unit "the life of the plants in thecomprehension teaching design, and through the application of experimental test and discussthe effect of comprehension teaching science in primary schools. Application experimentresults show that:1. The comprehension teaching can help improve students’ science learning attitude；2. Understanding the teaching helps to develop student’s scientific cognition, promote thetransformation of the concept of students’ science, caused the deep understanding of students；3.
