Amesbury: One of three teams of Amesbury High advanced math class leaves Lowell's Boat Shop on a field trip, part of a developing program funded by a $10,000 grant from AEFI. The students rowed the dories and used sextants to measure angles between objects along the river in order to calculate the height and distance of each landmark from one another, creating a more accurate scale for a map they have created during previous visits to the boat shop.
