Standards SPI 0707.T/E.3 Distinguish between the intended benefits and the unintended consequences of a new technology. SPI 0707.T/E.4 Differentiate between adaptive and assistive bioengineered products. SPI Explain the basic functions of a major organ system. What are the intended benefits and the unintended consequences of the new technology? Are we able to differentiate between adaptive and assistive bioengineered products? What is the basic function of the skeletal and muscular systems? How do they work together for survival? Essential Questions

Biomedical engineers use their knowledge of the human body to design technologies to solve problems related to biology, health, and medicine. Biomedical engineers collect and analyze data about the human body to help inform the design of various technologies, such as prosthetics and pacemakers. In this challenge, you and your team will take on the role of a biomedical engineer as you collect data for an athletic shoe company, design and create knee braces for an injured knee, and design and create biomechanical equipment for a specific sport. Your team will focus on the muscular and skeletal systems (i.e. musculoskeletal system) and how they interact with one another. Your knee brace must support a model injured knee to enable it to move like a healthy knee, while at the same time being cost- effective. The biomechanical equipment for a specialized sport must either enhance performance or prevent injury, while also being cost-effective.

Restate your problem State what you already know List any limitations or controls

Research the following topics: Biomedical engineering or bioengineering Biomechanics External parts of the foot Muscular and skeletal systems—specifically how they interact with one another Muscular and skeletal systems—specifically how they interact with one another Internal parts of the knee Action research on foot shapes, sizes, and arch heights Knee braces Knee braces Your selected sport & biomechanical equipment Brainstorm ideas with your team for each problem.

Goal: To work as biomedical engineers to design a knee brace for a model of an injured knee. Your knee brace has to help the injured knee move like a healthy knee. What do you need to know before you start designing your knee braces? Examples: What materials do we have available? How is the knee injured—what is wrong with it? How should a healthy knee move?

Create Create your knee brace according to your plan diagram. Test your knee brace on the injured model knee. Score your knee brace on range of motion, usability, and durability. Make improvements on your knee brace. Re-test your knee brace on the injured model knee. Re-score your improvements Each team member will turn in their final score. Improve

What aspect of your design did you try to improve? What did you change? Why? Did any parts of your total score increase (improve) on your new design? Did any parts of your total score decrease? Why do you think so?

Pick an Olympic sport (winter or summer) and design either a piece of equipment that will enhance the sport or help to prevent injury. You must research the Olympic sport in depth, including common injuries related to the sport.
