Vibrations

Causation: How sounds are experienced.

This week we conducted a number of experiments to help the children understand that sound is made when something vibrates and causes sound waves to travel. We started by placing our hands on the side of our throats and made different sounds. The children were able to feel the different vibrations when they talked, hummed and whispered. The children began to understand that when they stopped making sound, the vibration on their throats stopped.
After conducting experiments, the children had a better understanding that when vibrations stop so does the sound. We concluded by making telephones.  There was lots of giggling as the children talked to one another using their phones. The children were amazed that the sound (vibrations) could travel from one end of the cup to the other.

Instrument Sounds

As we examined the sounds in our environment, the children asked to learn more about sound from musical instruments. I had a tray of instruments for the children to play and they took turns trying each instrument. The children tried playing the instruments in a variety of ways: tapping, rubbing, blowing.
Oliver: I like playing the bongo.  It's loud. Sophie: I like to play the xylophone. I make sound when I hit it. Jayla: I like playing the cymbals. Alan: I like the harmonica. It sounds like a train. Grace: You use air to make sound on the recorder. 

After taking turns, each child chose an instrument to play.  Grace said they sounded like a band when they played together.
We also played a game on the smartboard. The children had to listen to a sound and match it to the correct instrument.  Here is the link: http://boowakwala.uptoten.com/kids/boowakwala-adventures-orchestra-guessinstruments.htm




Sounds In Our Enviroment

On Wednesday afternoon, Sophie asked to have the vacuum turned off because the sound scared her. Her comment prompted our discussion today as to how environmental sounds cause certain feelings to arise.  We revisited the sounds we heard on our walk and discussed if any feelings arose from hearing these sounds.  None did but the children recalled hearing thunder the previous week.  The children found the loudness of the sound of thunder scary. We ended group time by playing charades.  We took turns expressing different emotions and ideas through the use of sound.


Listening Walk

What are the sounds in our immediate environment?

The children listed some sounds they thought they would hear on our listening walk:
Jayla - dogs
Grace - coyotes howling
Byron - cars
Tyreese - birds singing
Sophie - a horse
Esme - people sounds.

It was easy for the children to list what would be expressing sounds but difficult to describe these sounds with language. For example, when asked what sound people would make, the children stomped their feet. For myself, I never realized until today how difficult it is to describe sound!

Our listening walk was very enjoyable. We heard everything on our list except for the coyote! We also heard the wind blowing, leaves crunching under our feet and a garbage truck.
The most exciting part of our walk was when the children discovered
 they can make sounds using their bodies or other objects around them.  This led the children to begin tapping rocks to make different sounds. Esme suggested we sing a song.  While the children tapped rocks togethe…
