In expedition, we conducted an experiment to investigate how the volume of sound made is affected by the distance a rubber band is pulled back. We placed a rubber band around the carboard box and pulled it back different distances. We measured the sound it made using a sound meter. We then recorded these results in a table. We concluded that when the rubber band was pulled back further, it was louder. This was because the vibrations were larger. When the distance was shorter, it made a quieter sound. This was because the vibrations were smaller. We then used the results to draw a line graph. We used our recent maths knowledge (statistics) to help us figure out the scales for the axis. We were really resilient doing this and had some great line graphs!
