Remy Dou's high school students are developing plants that can survive in space. They are learning to master aeroponics, an engineering process in which a nutrient-rich mist is sprayed on the roots. Requiring no soil and very little water, the plants can grow even inside the International Space Station, though Planet Earth is also an option.
Dou, a 27-year-old teacher and science director at Miami Christian School in Florida, works project-based learning into a range of classes in botany, biology, chemistry, physics and environmental science.
Dou's students have designed inflatable boots to walk on water, catapults, popsicle stick bridges, and even gasoline-powered launchers that hurl one-pound weights. This last challenge was retired when some of the launcher designs proved to be dangerously powerful.
