Ask students to staple together the construction paper with the previously cut window and the paper with the complete drawing. The papers should be stapled on one side such that they can be flipped open. Moreover, the fossil fragment diagram should only show through the construction paper window. This format enhances the presentation of original (fossil fragment) and completed diagrams to other students (see Figures 8 and 9).

Ask students to make an oral presentation in which they describe the habitat, diet, behavior, and other characteristics of the organisms they have extrapolated from the fossil fragments. At this point you might ask whether some students knew in advance what organism their fossil fragment came from (e.g., coral). Ask those students, if any, whether their knowledge affected the inferences they made about the habitat, diet, etc., of the complete organism that they inferred from the fossil fragment.

You might want to explain that scientists’ prior knowledge often influences their interpretations of the data and affects their conclusions. It would be interesting to compare those organisms that different students have inferred from similar or identical fossil fragments.

Continue by asking: “Is it possible that scientists face a similar situation?” “Can scientists differ in the inferences they derive from evidence?’ “If yes. How can such differences be settled?” Explain to students that all too often scientists may reach deferring conclusions based on the same evidence, just as the students have done in this activity. Scientists also often hold their views strongly and do not give them up easily.
