Therefore, it would be logical and reasonable for teachers to incorporate children's drawings into building science concepts. To demonstrate how drawings are utilized to help a child to acquire a science concept, the article first presents a vignette of an interaction between an adult and a 5-year-old boy, focusing on the science concept of the physical characteristics of a spider. It is then followed by several analytical explanations of how drawings build children's understandings. Not only are the introduced strategies useful for one-on-one interactive communication, but also applicable to a small group of young children.
