We learned all about sound sources (things that make vibrations) and sound receivers (things that detect the vibrations) including how certain animals generate and receive "sound". Ask your kiddo how a fish, grasshopper, and snake communicate!
With the use of the tuning fork and long gong the boys and girls looked for vibrations at the sound source, identified sound receivers, and compared sound volume/vibration intensity. They explored the vibrations using the instruments as well as other tools such as a ping pong ball, water, paper, and their own cheek!
The main take away point from today was for the kids to not just understand but experience that sound is caused by vibrations :)
