As part of our preschool schedule we have Nature Study. My daughter has a science journal that we also use for our nature study since that is a part of science. In this journal she draws and records her experiments and nature findings. Yesterday we went out and gathered some rocks that she then inspected with her magnifying glass, and drew in her science journal.
I will always cherish her drawings from preschool. These are her renditions of the rocks she found and looked at.
