The theme of the international 2016 Clean Tech Competition is “Making an Impact.”  Teams of 1-3 students (ages 15-18), assisted by a parent/teacher/mentor, must identify a problem involving plastics and/or the need for clean energy and then develop an original solution.  Teams should register now and submit their papers by March 18, and 10 finalist teams will prepare prototypes and presentations for prizes.  The contest is sponsored by the Center for Science Teaching & Learning.
