Foot and Leg Bones
Part 2 -- Begin by asking the students if there was anything that surprised them from part
1. Explain to them that they are going to compile their data onto a class data table in order to draw conclusions about the total number of bones in the body. Provide them with a data table that they can record their group results.
Skeletal Sections Arm
Class Data Table Group Totals
Explain: Once the totals have been recorded discuss the varying answers for each group. Ask them if it is possible that some bones were missed. After this discussion explain how averaging can help determine a more accurate count for each section. Average the results for each section and then total all of the averages together in order to obtain a skeletal grand total. Tell students that the correct number of bones in your body is 206. Discuss why their grand total may be different.
