It’s difficult to think of a tool we use in science classes that provides as much for student learning as a science notebook. It supports the development of science skills, processes, and understanding as well as literacy, numeracy, and attitudes. It helps students understand the scientific endeavor through modeling the work of scientists—recording information and data while providing predictions and personal analysis of discoveries. Add to that the success reported when using science notebooks to enhance science content and process skills with English language learners. However, this foolproof tool must be structured carefully with the developmental age of students and goals clearly in mind.
