Year 4 (Class 11) - Science - Vibration Strength

Class 11 have been looking at sound in science this half term. Today they decided what experiment they could conduct to answer the question “How does the strength of vibration effect the volume of sound?”

They worked in groups to decide how the experiment should be conducted. As a class they wanted to play an instrument, softly then hard, and record the volume in decibels.

They made sure they played the instrument from the same distance away from the data logger each time.

Together we recorded the results. We found the hard the instrument was played the louder the volume.
