STEMsters, the Mars High School Chapter of a national nonprofit, strives to develop a love for STEM among young students through an interactive activity-based learning experience. A typical lesson from STEMsters starts with a presentation that goes over an experiment and the instructions. With a worksheet to track and plan out the experiment and review STEM concepts involved, students then build the project with instructors hands-on guidance. Experiments are tested and the science concepts behind the projects are explained.
