Blue Electrode: Turning Saltwater into Fresh Water

Princeton Charter School, New Jersey
2022–2023; Fourth Place National Challenge

This middle school team proposed pairing two purification methods: electricity to remove salt from water, and a special filter to block salt and other contaminants. By combining the methods, they aim to make the process more efficient, using less energy and creating less waste.

GraphTech Graphene Adhesive: Better Bonds, Less Waste

Hudson Middle School, Ohio
2022–2023; Third Place National Challenge

The innovation is in the mix: a small amount of graphene, a carbon-based material, added to adhesive. The team’s concept aims to make adhesives stronger and more reusable, helping labels and tape stick securely, then peel off more cleanly with less damage and residue.

SERE Concrete Solutions: Concrete That Repairs Itself

Jefferson Middle School, Michigan
2023–2024; Second Place National Challenge

The repair is built in: special bacteria inside the concrete create limestone when water enters a crack. The team’s concept aims to help seal cracks in roads, buildings, and bridges, making infrastructure safer while reducing waste and environmental impact.

Plaque Tracker: Spotting Trouble Before Cavities Start

Science Scholars Sandbox, Illinois
2025–2026; First Place National Challenge

A color change could provide an early warning for tooth decay. The team’s concept uses a special gel that changes color when plaque bacteria produce acid. A sensor sends the results to an app, helping users spot problem areas and take action before cavities develop.
