Over the past two days, first graders have been exploring sound vibrations through the use of tuning forks! After mastering how to get the tuning fork vibrating and making a sound, they did a few experiments which made the vibrations much more visible to them - they touched the vibrating tuning fork to a piece of paper, to a "drum" with glitter on it, to a dish of water, to a ping-pong ball, and to their elbow while their finger was gently placed in their ear. All produced some very fun and clear results! Ask your child about them!
