The Siemens Foundation, Discovery Education, and NSTA are partnering for the third year of this national sustainability challenge, which has expanded to include high school students. The challenge encourages K-12 students to team with their classmates to create replicable solutions to environmental issues in their schools
(grades K-5), community (grades 6-8), and world (grades 9-12). Student and teacher/mentor prizes, which vary according to grade level, include savings bonds, school grants, and trips. For more information, visit “We Can Change The World”
