Year 6 have had a very noisy afternoon in Science today, investigating voltage!

Our research question was: how does increasing the voltage change the volume of a buzzer?

The children started by making a simple circuit with a 1.5 volt battery and a buzzer. They then listened and predicted the volume in decibels (dB) before using the data loggers to measure the exact volume.

It was quite a challenge but our class showed amazing resilience and teamwork skills to collect their data – well done!
