"If you are a K-12 student in the United States, your challenge is to create a digital 3D model of an object that could be used by an astronaut to maintain physical health on a 3-year mission to Mars. Your design must be intended to be 3D printed and could be used for a range of medical needs including diagnostic, preventative, first-aid, emergency, surgical, and/or dental purposes. While exercise, psychological, and nutritional health are important, they are not priority areas for this challenge. Retired astronaut Scott Kelly�s historic one-year mission on ISS provided insights on how the human body reacts to long duration spaceflight, but the Journey to Mars will take approximately 30 months. What health-related items do you think an astronaut will need on that journey, and why would these items require a 3D printer? It�s time to start flexing your problem-solving and design skills to find a solution � good luck!"

"Game-based learning is moving into the mainstream as more platforms become available and more educators recognize the benefits of increased student engagement and achievement. On top of that, research shows some interesting side benefits. For instance, surgeons who play video games are 27 percent faster at advanced surgical procedures and make 37 percent fewer errors than colleagues who don't play. Educators can incorporate game elements, such as rewards and engagement, into learning in two ways: games and gamification."
