Can we have vibration without sound?

When we have a question about how something works, our first step to answering it is careful observation. We use the following phrases: "What do you notice about it?" "What do you think?" As inquisitive friends we are always fascinated by cause and effect. It encourages the asking of questions and the seeking of answers to those questions through investigation and exploration. 

We are constantly engaged in making meaning of the world and sharing our perceptions. Innately curious, we explore, manipulate, build, create, wonder, and ask questions naturally. We take a chance to question a firefighter whom we happens to be around our neighborhood. Being a supportive friend to our interests, the firefighter delightedly shares his knowledge and expertise with us unhesitatingly. 

Friends with inquisitive minds love explore new ways of thinking and apply them to the world around us - thus providing us with hands-on learning experiences and knowledge that we have discovered on our own. Interacting with natural environments allows us to learn by doing and experiment with ideas. In nature, we think, question, and make hypotheses - thereby developing inquisitive minds. 

In relation to our ongoing inquiry, we ask ourselves on how to recognize vibrations. Do we see it? Do we hear it? Or do we feel it?
A collection of various thoughts sparks around our group discussion area.
Vivaan: "We hear the vibration".
Felix: "We hear the vibration".
Brooks: "We feel the vibration".

Throughout our process of building-up a shared understanding on the relationships between sound and vibration, we discover there are so many elements of sound - pitch, resonance, etc. What are the connections among them? What are the differences?

We try to firsthand experience the relationships between vibration and sound in many ways. We refer to the musical instruments to experiment our wonderings.

We experiment with the shaker. We ask ourselves if we hear the sound or the vibration. 
“It’s only the vibration” - Nora.
Lukah encounters, "It’s only the sound”.
Vivaan attempts to identify the difference between the sound and the vibration by making some sounds.
​However, Felix agrees that vibration comes by itself.

Another interesting idea, to figure out, brings us to another learning experience - a medium of art. We attempt to understand whether we can encounter vibration without sound.

We always try to revisit our experiment and go deeper as much as we can. So this time, our focus is the sound, vibration and the air. We try to ask ourselves that what makes the bubbles move when we blow it?

This time we come up with a different material which is a straw, instead of a bubble blower. It helps us understand more about the role of air, going through the straw medium, for making our beautiful art.

Vivaan mentions, “There are three things happening which is sound, vibration and the air”. We extend his wondering and ask, “Does the vibration come together with the sound?" He says, “I can only feel the vibration and the air but the sound I can hear”. “ I can feel the vibration in my body when I blow the bubble”- Nora.

We believe in expressing our thoughts and wonderings through drawing. Today, we converse about how we actually see what we think. We ask ourselves what makes the bubble to come out?  Vivaan mentions about the air. So he draws his own imagination and exploration. He further mentions that vibration is louder than the sound and the air is quieter than the sound.

Wishing you a beautiful journey dear Elie! You will be sorely missed indeed. Your creative and insightful mind, loving and caring heart are always being part of who we are here at Children & Friends. Love you and hugs from all of us!

Kindest,
