It is not likely six of Oasis Middle School 's seventh -graders will be traveling to the moon anytime soon. But their wastewater recycling design could!
The team of girls collaborated and came up with a solution using three two-liter soda bottles. They cut the tops off and created one long tubular structure held up by wooden posts. The girls made a simulated wastewater by combining salt, baking soda, salt, vinegar, ammonia and baby shampoo.
The solution was poured through a filtration system including charcoal, sand, gravel, coffee filters and a paint filter. After its cycled through, the liquid sits in a bunch of crushed Moringa seeds. Moringa is a vegetable tree with a variety of potential uses.
And through the design process, Danielle Gabhardt, 13, remembered she learned about one of those uses through a trip to ECHO in North Fort Myers.
"Third-world countries use Moringa seeds and pour them into water in order to have a stable water supply," Gabhardt said.
Dunn noted that through the process, the seeds can take out 99 percent of the bacteria in water where there is no filtration system.
Even if they don't win the contest, the group members said they've been intrigued with the engineering process.
"We're proud of ourselves," said Brittany Skinner, 12. "This project isn't that easy to do."
