Why Open-Sourced and Free

At FLOWERS, we believe water, engineering, research, and science education should be accessible to every student — regardless of background, school district, or financial situation.

That’s why our curriculum, activities, and worksheets are open-sourced and free to use. Teachers, parents, and community organizations can access our materials, adapt them, and bring hands-on STEM learning into their classrooms.

By keeping FLOWERS free, we ensure that cost is never a barrier to sparking curiosity, building skills, and inspiring the next generation of leaders in water and engineering.

How We Started

The FLOWERS Program was created at the University of South Florida in the College of Engineering to inspire the next generation of STEM leaders. Founded in collaboration with Dr. Maya Trotz and student mentors, FLOWERS connects young learners to the world of water, engineering, research, and sustainability.

Our first cohort launched in Summer 2025 with students from across Tampa Bay. Through weekly lessons, projects, and field trips, students explored the science of water and how it connects to their everyday lives and future careers.
