FSE students take science outside the classroom. Fourth grade students at Waller ISD’s Fields Store Elementary have been studying about the earth's volcanoes, rocks, minerals, and the effects of weathering during science lessons. March 14, students in Mr. Nesloney, Mrs. Mayfield, and Mrs. Eckermann’s classes ventured outside the classroom for some hands-on learning. They used their new Science Lab to construct their own volcano and fossil.
