Biomedical engineers play a very important role in medicine. They design technologies that help solve problems with the human body, which can include x-rays, artificial limbs, casts, braces, and even surgical instruments. They work closely with doctors and nurses to improve upon technologies that already help solve problems related to medicine and the human body.
Working in teams of three or four, fourth graders are planning their knee brace designs. They are thinking about the injured knee's range of motion and the materials they have available. Each group's plan had to be approved first. Notice how each team's plan is unique. This will give students an opportunity to think about how each design meets the criteria of the challenge, yet be designed differently. Each brace must allow for the range of motion of a healthy knee, be able to be put on and taken off in under an minute, and be durable enough to wear again and again.
