Year 4 Computing: Measuring Sound with BBC micro:bits

This week in Year 4 computing, pupils became real digital investigators as they programmed BBC micro:bits to create their own noise meters. Using simple coding, the children learned how to program the micro:bits to measure and display sound levels, developing their understanding of inputs, outputs, and algorithms.

Once their programs were working, pupils explored different areas around the school to collect sound readings. They worked collaboratively and responsibly, taking measurements in classrooms, corridors, and quieter spaces. The data they gathered helped them answer a key enquiry question: “What is the quietest part of the school?”

This practical lesson encouraged pupils to apply their computing skills in a real‑world context while also developing teamwork, problem‑solving, and evaluation skills. Pupils were challenged to think carefully about accuracy, repetition, and fairness when collecting their data.

The lesson generated plenty of excitement and thoughtful discussion, and pupils were proud to see their coding skills having a real purpose. Year 4 showed fantastic curiosity and resilience as they explored how technology can be used to investigate and answer meaningful questions.
