Ask the class to note whether there seems to be a relationship between the size of the bone and the length of healing time. Back to Top For younger students, you might want to utilize a simpler graphing project. The survey could only collect data about which students had ever broken a bone and which bones they broke. You could then have the class create a bar graph for the various bones, indicating how often each had been broken for class members. The graph would then indicate which bones seemed to be the most and least likely to break.
Students can also develop individual graphs depicting the information they have gathered.
When they are finished, they can share their graphs with the rest of the school. Back to Top 1. Discuss how the x-ray machine has changed the treatment of broken bones. Healthy bones are always growing. Our bodies repair them when they age.
