The bones are particularly strong in the longitudinal direction; that is why many bones are aligned vertically in your body. Since the bones are so strong, one of their tasks is to carry your body weight. Have you or one of your friends had a broken bone before? Doctors probably put a hard and thick cast around the broken bone, so it can heal without being disturbed. Although the current casts are successful at protecting the bones and making them as strong as before, the casts are often uncomfortable because they are bulky. Additionally, since the cast completely covers the skin around the broken bone for a long time, undesirable skin reactions such as itches and rashes are unavoidable.
The student handout will be given to all students working on the design challenge. It gives a brief recap of the story, it helps the students identify what they are attempting to achieve, and it recaps the design process.
Bone Fracture Fixation TEK8 Instructor’s Guide
This Instructor’s Guide provides the instructor additional information on how to run the design challenge with alternatives for materials and test setups as well as information to help make the design challenge a good educational experience.
The Telling the Story Video conveys the societal impact of the student’s research that is the basis for the design challenge and will set the problem-solving context for students.
The Design Challenge Video leads students through the design process. It indicates materials available, states what the criteria are for success and any constraints. It also gives a second ‘level’ of the design challenge that allows ‘early completers’ to move on to a slightly more difficult challenge.
The presentation can be used in conjunction or in place of the Design Challenge Video.
