Similarities and differences observed among the specimens lead to further discussions of form and function, trends in shared characteristics, and links between groups.

This classroom kit contains everything required for the dissections, plus a detailed instruction manual with reproducible blackline masters, background information, dissection guides for each of the 9 animals, reflection questions, and extension activities.
