Have your students practice the science process skill of inferring with shells. When you infer, you draw a conclusion based on information not directly observed. In this lesson, students are given a piece of a broken shell. They are asked to observe its properties and infer what the entire shell looked like before being broken, then complete their inference by drawing. Teacher instructions, scoring rubric, recording page, narrative writing page are included in this lesson packet.
This lesson is in the green book Rising to the Challenge of the National Science Education Standards, also sold on this website. This is lesson five that will also be available for purchase in a packet of nine process skill lessons on shells.
