As part of our Y4 sounds topic in science, The Puffins and Golden Orioles decided to plan an investigation to see how long it takes for sound to travel 150m. We signalled to the other class, then clashed cymbals to create a very loud noise. The action was logged immediately, and stopwatches were used to time the sound at the other end of the field. Our findings? Using our maths skills, we worked out the average, which was approximately half a second!
