This week we had a visit from our Four Winds volunteers, Heather and Susan! The topic was "sound". The class had the opportunity to explore sound waves. They used film canister shakers filled with things that produced different sounds to see if they could match those with the same sound. They also used tuning forks (and hand claps) to try and make sugar "dance" on plastic wrap covered cans. They were really excited to see the sugar dance when they brought the tuning forks close. One activity may bring back memories...they went into the hall to "talk" to each other using an old-fashioned "telephone" made with a long string and two soup cans! They also used unusual contraptions made with string and metal coat hangers to hear how sound travels when the hanger is tapped with a metal spoon. Our afternoon finished by enjoying a crunchy, noisy snack! By covering their ears while chewing, the sound becomes amplified! What a fun afternoon!
