Sound
Alder Class enjoyed investigating how sound travels through a solid using string telephones
We also investigated sound echoes in our outside classroom
Some of the Year 4s even chose to investigate the echoes in the tunnels during their own break time!
Investigating how sound travels through a liquid medium by tapping rocks together underwater and using a bottle to listen
Investigating how sound travels through a gas medium by listening to our partner's voice through a balloon
We conducted an experiment to see if dropping a marble onto a drum from a larger height made a louder sound
Alder Class enjoyed exploring how many decibels of sound there were in our classroom by conducting different simple activities using an online decibel meter
Conducting an experiment to see how sound fades as you get further away from the sound source by playing music through a speaker, measuring different distances away from it and using an online decibel meter to see what volume we hear at that distance.
