Continue the Year 6 Science unit on electricity with this How Can We Change the Volume of a Buzzer? Investigation Lesson.

In this PowerPoint, pupils will recap key vocabulary linked to circuits and then learn about buzzers: what they are, where they might be encountered, what they produce and how it is measured. For their investigation, they will explore how changing the number of batteries affects a buzzer in a circuit by creating a simple series circuit with one battery and one buzzer, then changing the number of each component and recording how the buzzer's sound is impacted. They will present findings in a bar chart, draw a circuit diagram and analyse why the buzzer produced the loudest sound in a particular circuit, before thinking about how appliances with buzzers might be adapted for those with hearing issues.
