In Science trios, we have begun testing the interesting the question: Does sound travel slower than light? To do this, we measured 150 m in three sections of 50m In turns, at each point, a person was holding a balloon and a pin. At the starting point, two children with synchronised stopwatches waited to either see or hear the balloon pop at each distance. When heard or seen, the stopwatches were pressed and the times compared to see if there was a difference. We predicted that the further the distance of the balloon popped, the slower the sound travel... We can't wait the receive everyone's results and compare for validity!
Sound Investigation - Can We Trick Our Auditory Nerves/Brain To Thinking Sound Waves Are Coming From A Different Direction?
After learning more about the outer, middle and inner ear, Willow Class took part in a sound investigation to see if we could catch sound waves and trick the auditory nerve/brain into thinking that the sound made is coming from the opposite direction! Interestingly, many members found they could by using well-structured funnels and transport tubing! Well done Willows!
After completing a sound investigation carousel which included observing how animal ears are formed, how some ears physically move to receive sound (almost like a funnel catching) and playing a variety of instruments to explore sound creation, we came to a collective scientific conclusion that sound is created through vibration. We also believe that ears sense this vibration somehow...
