The non-profit Center for Science Teaching & Learning runs the Spellman High Voltage Electronics Clean Tech Competition, in which teams of 1-3 students (ages 15-18), assisted by a parent/teacher/mentor, identify a problem within the theme of “Solving Climate Change” and then develop an original solution.  Teams should register by March 16 and submit their papers by April 13, and 10 finalist teams will prepare prototypes and presentations for prizes.
