Science teacher Earnie Olsen, center in background, carries 10th-grader Billy Gomez as other students from the Academy of Environmental Science hold hands and encircle Olsen and Gomez during an Amoeba Race at Fort Island Gulf Beach in Crystal River on Friday. The race is a team building activity that is part of the orientation process for the new semester at the academy, according to director Lisa Merritt. Two groups of students race against each other, she said. Students hold hands and form a cell membrane that encircles the nucleus, in this case Gomez. If any of the students forming the outer ring fall or break their ring, the cell membrane is ruptured and they must all stop and regroup before proceeding. After his team won the first race, Gomez said it was difficult. "It takes a lot of brains to figure it out because you have to make sure that everyone works together," he said. From left, students encircling Olsen and Gomez are Ashly Lindsey, John Boscarino, Mike Lewis, Amber Lawson and Jennifer Shear.
