Mariner students engineer portable energy systems

Mariner Middle eighth-graders in Ronald Maiuri’s science class recently put their engineering skills to the test during a hands-on lab. Modeling Portable Energy Systems was part of the school’s Harnessing Human Energy unit.

Throughout the project, students explored how different power sources can be used to generate electricity for a small fan, gaining real-world insight into energy production and sustainability.

Working in teams, students designed and built three types of portable energy systems using a battery, a hand-crank generator and a solar panel. As they tested each model, students compiled a list of advantages and limitations for every energy source, comparing reliability, efficiency and ease of use.

The experience culminated in a creative challenge: applying what they learned to design and construct their own original portable energy system. This final project encouraged students to think critically, problem-solve and innovate, all skills that are essential in both STEM learning and the world beyond the classroom.

The lab strengthened students’ understanding of energy concepts, and also fostered collaboration and confidence as they brought their ideas to life.
