Discover how to engage students in scientific inquiry and coding by designing a digital mood ring! This hands-on session will guide participants through the process of creating a “mood ring” that changes color based on temperature readings from a sensor. With simple coding teachers will explore foundational science concepts—such as temperature sensing, data collection, and thermodynamics—while introducing students to basic coding and data visualization skills. No coding or advanced technical experience is needed; this session is designed to equip all teachers with the tools and confidence to bring this interactive project into their classrooms. Teachers will leave with a project outline, sample code, and step-by-step instructions, making it easy to replicate in a science or STEM curriculum.
