When students design, build, test, and revise, STEM learning becomes authentic and memorable. In this session, participants will engage in hands-on STEM experiences that integrate technology, collaboration, and real-world problem-solving. We will model classroom-ready challenges that encourage curiosity, design thinking, and persistence across grade levels. Examples will include maker-centered tasks, interdisciplinary STEM connections, and technology-rich strategies that help students move from consumers to creators. Participants will reflect on how these experiences can be adapted for different contexts and learner needs. Attendees will leave with practical lesson ideas, implementation strategies, and a stronger understanding of how technology can deepen hands-on STEM instruction.
