Waves of light, Waves of sound

"It feels like the ocean over here."

The November workshop was designed to interact with light. 

Light tables, projectors, translucent and transparent materials, and reflective materials, were available for messing about. 

During the square phase (discussion phase) of the workshop we discovered we were talking about sound: 

We wondered why a workshop about light would lead us to a conversation about sound. One participant offered: 

"It felt so quiet this time."


"I noticed that when I started to do something a little louder, I felt almost bad that I would disturb people."

"In my classroom I notice that I am so careful to honor the children who need quiet."


"Can we think about shaping the environment to honor the children who need loud as well?"

"As I was driving over, I was pondering light and that it is made of waves. 
Sound is waves as well - different lengths of waves."

"A wave can be described as a disturbance that travels through a medium from one location to another location. 
A Wave Transports Energy and Not Matter" - the Physics Classroom

How can we explore this connection between waves of light and waves and sound as teachers? In the classroom? What other types of waves can we explore? How can we use light waves and sound waves to transport energy in the classroom?
