In this unit, students learn how to program a sound, a soil-moisture, and an environmental sensor using a micro:bit--a learning tool used by millions of young learners worldwide to get hands-on experiences with computer science and technology. In so doing, students gain a deep understanding of how sensor systems work and how they can be used to collect, analyze and display scientific data to support scientific investigation.
Students work in expert groups focusing on one sensor and then share findings with the class to build knowledge collaboratively. The unit leverages proven pedagogical strategies such as a driving question board and conceptual model development; group work, collaboration, and accountable talk are emphasized throughout the unit. The unit concludes with an in-depth project where students build a display or conduct an investigation that is personally meaningful.
