Making Glass Sing

The last experiment in our sound unit was a fun one! The class tried to determine the best way to make a glass sing. Starting with the basic trick of rubbing a finger along the rim of a glass to create a high pitched ringing sound, they formed questions and designed experiments.

After groups decided on their question, they chose containers to use for their experiment.

Will it sing with pop in the glass?

What effect does the liquid in the container make on the sound?

Can you imagine what it sounded like in our classroom that day?

My apologies if any fifth grader brings this noisy activity home to the dinner table! :)
