Students often struggle with the concept of homologous and analogous structures, especially in on-level Biology classes. This activity is designed to provide both virtual and hands-on options for teachers based on the needs and strengths of their students. Students will compare and contrast the morphology of vertebrate forelimbs, and will use this knowledge to draw conclusions about their common ancestor and descent with modification. Students will also consider adaptation and how structure is shaped by selection pressures to suit the necessary function of limbs.

I love the idea of having physical models for the students to explore in addition to virtual/digital resources. How did you print the 3D models in creating your physical "limb puzzles"? How did you attach the magnets? Looking forward to trying this activity.
