Level 2 Chemistry classes at LOLHS recently participated in the US Crystal Growing Competition 2016 sponsored by the organizations shown below and won second place nationally Overall for the second year in a row for grade 9-12 participants. We also placed 5th for Crystal Quality for grades 9-12 participants. Over 90 schools participated in this competition where students were challenged to grow the biggest single crystal of alum (aluminum potassium sulfate dodecahydrate) in 5 weeks. These crystals form large, clear octahedral shapes when grown under controlled conditions. Students used their knowledge of solutions discussed in class to first grow a seed crystal, then suspend it in the solution to grow a large, single crystal. They monitored their seed growth and made adjustments to maximize size and clarity of a single crystal- not an easy task.
