Physics of Sound!

Today we had a visitor who showed us what sound looks like!
Yes, you can actually se sound - if you have an Oscilloscope.

The class have been working with sound in science class for a while. Today K brought her stepfather D in to show us this. He is a physics professor at the University of Scranton and he brought in some instruments and things on the matter of sound. It was a really great opportunity for the students to get to see a demonstration of sound waves. We got to listen to sound resonating cylinders, and with the oscilloscope we could also see how the waves changed if the sounds had a high pitch or a low pitch, or a high or low amplitude (volume). It was really interesting and the students remembered a lot from their sciens classes. A lot of good questions were asked too!

Thanks K for this great idea, and thanks D for coming in to show us. It was a really nice and interesting lesson!
