In this interactive session, participants will explore how to seamlessly integrate Social-Emotional Learning (SEL) into STEM activities for K-5 classrooms. Through hands-on experiences, attendees will engage with challenges paired with SEL strategies that foster empathy, resilience, teamwork, and problem solving. Participants will collaborate in small groups to craft collaborative STEM challenges that are infused with SEL competencies to enhance the learning process. By the end of the session, participants will have practical lesson ideas, a curated list of SEL focused STEM books, a list of participant-generated STEM challenge ideas and tools to assess SEL growth. Participants will leave prepared to create a learning environment where young engineers can develop both technical skills and emotional intelligence, preparing them for future academic and personal success.
