Comparing the human skull to other primates and extinct hominids is considered an important lab activity in high school biology. There are many versions of this lab available, where students can compare the similarities and differences between the different species and observe the pattern of the gradual accumulation of traits over time, leading to modern humans.

Unfortunately, skull models can be very expensive; some sets can cost thousands of dollars. This investigation is cost-prohibitive for many educators and families. The Teacher Institute for Evolutionary Science has created a skull comparison investigation that can be completed at no cost. The activity includes a slide show explaining each measurement the students will take (facial slope, prognathism, cranial cavity capacity, etc.); as well as informational handouts, a blank data tables for collecting data, links to Smithsonian’s 3D skull collection, and final assessment questions.

During this session, Ms. Vazquez will show the attendees where to access all the free materials to successfully complete this activity and walk the attendees through the basics of the lesson, so that they are able complete it with their learners in their home or co-op.
