In the World Solutions Challenge, students submit an action plan describing their solution and a supplemental item supporting their action plan. Teams of 2 to 4 students in junior grades 5 to 6 (ages 10-12) and middle grades 7 to 8 (ages 12-14) address a topic and solve for the biggest problem they find. In 2026, the supplemental item is required and may be a video of up to 3 minutes, an audio file of up to 3 minutes, or up to 4 pages of diagrams or graphics.
Below are samples of supplemental items submitted during the 2025 World Solutions Challenge addressing the topic of Rising Sea Levels.
