Have your students develop their own classification system for a group of sample shells. The science process skill of classifying is critical for the understanding of later more complicated classification systems. Teacher instructions, scoring rubric, recording page, Science Notes with writing page and rubric, and open ended classification concept map, are included in this lesson.
