Student-Designed Experiments Using Raspberry Pi and Micro:bit Environmental Sensors

Although low-cost computing platforms such as Raspberry Pi and Micro:bit are increasingly used in science classrooms, adaptable instructional materials that accommodate teachers across a wide spectrum of technological and pedagogical experience, support differentiated instruction, and enable student-designed, inquiry-based investigations remain limited. This article describes a classroom activity using Micro:bits and data sensors to help students design and conduct their own experiments in grades 6-8 environmental science classrooms. Working in small groups, students assemble kits, test sensors using common household materials, and design a testable experiment related to a local environmental issue. A free, online lab manual accompanying this activity provides step-by-step instructions, photos, and extension ideas. Teachers can adapt this activity to a wide range of NGSS standards, classroom settings, and student skill levels by adjusting pacing, providing scaffolds for beginners, and offering extensions for advanced learners. Strategies for differentiation, classroom management, and both formative and summative assessments are discussed. By combining interactive learning with affordable technology, this activity builds student engagement, critical thinking, and STEM skills while connecting science to real-world community issues.
