Compare a Human and Chimpanzee Skeleton
This handout can be used in discussions on the evolution of bipedalism or in any unit on the skeletal system. Students label the bones of the skeleton and make comparisons between the forelimbs, hind limbs, and pelvis. I created this handout to compliment an evolutionary lesson and video from HHMI on the “Origin of Humans”…

Investigation: What Factors Affect Lung Capacity
In this investigation, students use balloons and rulers to estimate the vital capacity of lungs using test subjects within the class. To perform the test, subjects take a deep breath and blow into a balloon. The diameter is measured and a graph is used to estimate the volume of air expelled based on the diameter…
