Sound - liquid audio

This week we were learning a bout sound how it travels and  what it is. We discovered that sound is vibrations traveling through the air and into our ears which are like satellite dishes picking up the sound waves and decoding them in our brains. One of our experiments was covering a speaker in a plastic bag and putting liquid on the speaker. Then we played a song to see what the results were. We each discovered something about sound and it was a fun way to learn.
