The digestive system is amazing: it takes the foods we eat and breaks them into smaller components that our bodies can use for energy, cell repair and growth. This lesson introduces students to the main parts of the digestive system and how they interact. In addition, students learn about some of the challenges astronauts face when eating in outer space. Engineers figure out how to deal with such challenges.

Just trying to take a drink or eat a meal in outer space can be very challenging. Scientists and engineers who work for NASA have designed special devices to help astronauts eat in microgravity. Students learn about some of these devices designed to help solve practical problems, and in the associated activity “Lunch in Outer Space,” they design and create their own inventions for easier eating in space --- just like engineers.List the major components of the digestive system.Draw a basic diagram of the digestive system.Explain how engineers work to resolve the challenges of eating in outer space. 30TeachEngineering.orgSara BornAbigail WatrousDenali LanderMalinda Schaefer ZarskeJanet Yowellhttp://www.teachengineering.org/collection/cub_/lessons/cub_human/cub_human_lesson04_map.pdfhttp://www.teachengineering.org/collection/cub_/lessons/cub_human/cub_human_lesson04_map.dochttp://www.nasa.gov/audience/forstudents/5-8/features/F_No_Pizza_in_Space_5-8.htmlhttp://www.spaceflight.nasa.gov/living/spacefood/index.htmlhttp://www.dupagehealth.org/health_ed/types.htmlFox, Stuart Ira.
