Ahhhhhh!!! That's all I heard after I downloaded the sound meter app on my phone. The girls wanted to make their screams get up to as much decibels as they could on the meter. Can you tell we are learning about sound this week? We've learned all about sound waves and how sound travels. Oh and ofcourse, the measurement of sound. We did some music fun, too. We made music with water and glasses. Each of the glasses had a different tone when hit with a spoon. The glass with the most water had the lowest pitch while the glass with the least water had the highest pitch. The girls understood that the vibrations are made when you hit the glass, this creates sound waves which travel through the water. More water means slower vibrations and a deeper tone.
