This document includes skeletons of early humans and Lucy and an article taken from National Geographic (credit to National Geographic) about Lucy and her discovery.
Read and discuss the article and skeletons with your students. Next, have your students compare their present day selves with Lucy. They will fill in a side by side chart with their dimensions compared to Lucy's. Some aspects they will compare are height, weight, gender, leg and arm shape, etc. There is also a spot for them to upload their own photo next to Lucy's.
A great way to read informative text and then relate the information to your students.
