UAF engineering students Jordan Merkes and Zach Alkire improved the OneTree reverse osmosis unit for their senior design project. "We increased the efficiency modification for birch sap reverse osmosis," Merkes explained. The machine, created by SNRE graduate student Tricia Kent, purifies birch sap and concentrates it down so it can be cooked into syrup.
A special treat occurred with OneTree Alaska Director Janice Dawe arrived from a visit to Juneau with historic pieces of mahagony from the Baranof Hotel and oak from the governor's mansion. OneTree will use them to make special knitting needles. Upon glancing at the historic wood, one of the seventh graders was so moved, he exclaimed, "I'm going to cry!"
Forbes got funding for the service learning component through a student achievement grant from Youth Service America and State Farm Insurance.
