By creating their own journal pages, children are able to depict their ways of seeing and understanding the science phenomena, constructing or reconstructing the phenomena through their own lens of experience (Shepardson, 1997). In this article, the authors describe their experience using science journals with nine first-grade students and seven second-grade students as part of a lesson exploring earth materials. Then they discuss what can be inferred about some of the students’ learning based on their journals’ content.
