With their plans officially approved, fourth graders are off creating their own knee brace designs. With a wide-variety of materials, students are creating a knee brace according to the following criteria.
1. The injured model knee with the knee brace attached must move with the same range of motion as a healthy knee.
2. The knee brace must be usable. That means it has to be put on and taken off in a specific period of time. Room 306 agreed upon 45 seconds and Room 308 agreed upon a minute.
3. The knee brace must be durable over time. This means that the injured knee with the attached brace must perform the same way after multiple uses.
