Green Heart STEM Challenge 2024: Students Solve Water Justice Issues in Atlanta and Houston

Captain Planet Foundation celebrated the work of over 350 student finalists across metro Atlanta and Houston at the Green Heart STEM Challenge for Environmental Justice finale events. This program, designed by Captain Planet Foundation and its partners, challenges young people to explore and identify environmental justice issues in their communities and to design feasible solutions to address these problems.

In its second year, the 2024 Green Heart STEM Challenge engaged students across both metro Atlanta and metro Houston. Each year the challenge identifies a specific theme inspired by the Planeteer elements; and this year’s theme was Water Justice. Participating students spent three months learning about water pollution, flooding, and water scarcity and studying how these realities impact the places they call home. With the help of their teachers, each team identified the root cause of an issue, then designed a solution to address it in an effective way. 

At each finale event, three teams from each age group – Primary, Junior and Senior – pitched their solution to a panel of judges. The judging panels were made up of professionals from the environmental field who exemplify advocacy in environmental justice within their careers. Equally inspired by the work of the youth standing in front of them, judges helped the students consider various factors of implementing their solutions.

The winning teams from each age group receive an implementation grant of $1,000 to carry out their solution and will attend the Idea Incubator week-long summer camp, where they will work with professionals from Captain Planet Foundation transform their idea into reality.


The final events in both cities rallied excitement around solving water justice issues. As the students witnessed their peers create effective solutions for problems within their community, many gained a realization that the power to create change and stand against injustice was well within their reach.
