Problem-solving challenge

From left, Dominic Perkins, Shaneria Griggs, Tristen McMahon and Juan Sauls continue their work on a "paper roller coaster" as part of a science project in Kendra Wilcox's sixth grade classroom at Hacker Middle School on Thursday. Using nothing but cardstock and plenty of tape, the students spent time during the week building towers, support beams, ramps and curves that were later used to guide marbles down these pathways. The project required the students to use basic scientific principles and problem-solving skills to overcome obstacles that kept the marbles from completing their journey.
