This is one of a set of curriculum guides for the Stoneham Elementary School Science Program (see SE 012 153 - SE 012 158). Each guide contains a chart illustrating the scope and sequence of the physical, life, and earth sciences introduced at each grade level. For each of the topics introduced at this grade level, an overview of the topic, a list of concepts to be developed, motivating ideas, suggested activities to develop each concept, a reading list, a list of supplies needed, and examples of student work sheets are provided. In most activities, the teacher is expected to involve all students in experimenting and applying scientific thinking. The topics covered in the grade two guide are: animal structure, molecules, plant diversity and structure, animal diversity and structure, and fossils and evolution. (AL)
