The project by students from Middlebury’s Aurora School has been selected as one of 20 finalists in NASA’s “Waste Limitation Management and Recycling Design Challenge,” says the Addison Independent. Fifth- and sixth-graders at the school developed two water recycling systems as their solution to NASA’s challenge to maximize the conservation of water by astronauts heading to the moon.”We did (the project) in the mess hall in the kitchen, with recyclables and whatever parents and friends would donate for us to use,” teacher and project coordinator Danielle Levine said. The next step is a PowerPoint presentation and phone interview with a NASA review panel, from which the top three entries are selected. Entries will be judged on creativity, water quality testing results, and sustainability of the design. The prize is an all-expense paid trip to the Kennedy Space Center in Florida. The winner will be announced in May.
